Comparison of effectiveness of three surgical methods in treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients

To compare the effectiveness of three surgical methods in the treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients, in order to provide reference for clinical selection of appropriate surgical methods. The clinical data of 103 patients with Pauwels type Ⅲ femoral neck fracture who met the selection criteria between June 2018 and December 2021 were retrospectively analyzed. The fractures were fixed with hollow screws in an inverted triangular shape (37 cases, hollow screw group), hollow screws in an inverted triangular shape combined with eccentric shaft screw (34 cases, eccentric shaft screw group), and hollow screws in an inverted triangular shape combined with medial support plate (32 cases, support plate group). There was no significant difference in age, gender, cause of injury, body mass index, time from injury to operation, side of the fracture, and Garden classification, whether they were in traction preoperatively, and other baseline data between groups ( P>0.05). The operation time, intraoperative blood loss, the number of fluoroscopy, the length of hospital stay, early postoperative complication and postoperative weight-bearing time of the three groups were recorded. Harris score was used to evaluate joint function at 6 and 12 months after operation, and the difference between the two time points (change value) was calculated for comparison between groups. X-ray films were reviewed to evaluate the quality of fracture reduction (Garden index) and healing, as well as the occurrence of internal fixation failure and femoral head necrosis. The patients of the three groups were successfully completed. Compared with the hollow screw group and the eccentric shaft screw group, the operation time and intraoperative blood loss of the support plate group significantly increased, the number of fluoroscopy reduced, and the quality of fracture reduction was better, the differences were significant ( P<0.05). The operation time, intraoperative blood loss, and the number of fluoroscopy of the hollow screw group were less than those of the eccentric shaft screw group, the differences were significant ( P<0.05). There was no significant difference in the length of hospital stay between groups ( P>0.05). All patients in the three groups were followed up 21-52 months, with an average follow-up time of 36.0 months, and there was no significant difference between groups ( P>0.05). The incisions of all patients healed by first intention. Imaging reexamination showed that there was no significant difference in the incidence of fracture nonunion between groups ( P>0.05). The fracture healing, partial weight-bearing, and full weight-bearing were significantly earlier in the eccentric shaft screw group and the support plate group than in the hollow screw group ( P<0.05). There was no significant difference in change value of Harris score, the incidence of postoperative deep venous thrombosis and femoral head necrosis between groups ( P>0.05); however, the incidence of internal fixation failure in the support plate group and the eccentric shaft screw group was significantly lower than that in the hollow screw group ( P<0.05). The incidence of postoperative lateral thigh irritation in the support plate group was significantly lower than that in the hollow screw group ( P<0.05); there was no significant difference between the eccentric shaft screw group and the other two groups ( P>0.05). The overall incidences of postoperative complications in the eccentric shaft screw group and the support plate group were significantly lower than that in the hollow screw group ( P<0.05). For young and middle-aged patients with Pauwels type Ⅲ femoral neck fracture, compared with simple hollow screw fixation in an inverted triangular shape, combined with medial support plate or eccentric shaft screw internal fixation can shorten the fracture healing time, reduce the incidences of postoperative complication, more conducive to early functional exercise of the affected limb; at the same time, the operation time and blood loss of combined eccentric shaft screw internal fixation are less than those of combined medial support plate internal fixation, so the hollow screw in an inverted triangular shape combined with eccentric shaft screw fixation may be a better choice.

Comparison of the safety and efficacy of robotic natural orifice specimen extraction surgery and conventional robotic colorectal cancer resection: a propensity score matching study.

Robotic resection is widely used to treat colorectal cancer. Although the novel natural orifice specimen extraction surgery (NOSES) results in less trauma, its safety and effectiveness are relatively unknown. In the present study, we used propensity score matching to compare the effectiveness and safety of NOSES and robotic resection for treating colorectal cancer. Present retrospective cohort study included patients who underwent robotic colon and rectal cancer surgery between January 2016 and December 2019 at the Department of Gastrointestinal Surgery, the Second Xiangya Hospital of Central South University. The intraoperative time, intraoperative bleeding, postoperative recovery, postoperative complications, and survival status of the conventional robotic colorectal cancer resection (CRR) (78 patients) and NOSES (89 patients) groups were compared. These results showed that no significant differences were observed between the two groups in terms of early postoperative complications, operation time, and the number of lymph nodes dissected. Compared with the CRR group, NOSES group had shorter postoperative exhaust time [3.06 (0.76) vs. 3.53 (0.92)], earlier eating time [4.12 (1.08) vs. 4.86 (1.73)], lesser intraoperative bleeding [51.23 (26.74) vs. 67.82 (43.44)], lesser degree of pain [80.8% vs. 55.1%], and shorter length of hospital stay [8.73 (2.02) vs. 9.50 (3.45)]. All these parameters were statistically significant (P < 0.05). However, no significant differences were observed in the 3-year overall survival rate and disease-free survival rate between both groups (P > 0.05). Collectively, robotic NOSES is a safe and effective approach for treating rectal and sigmoid colon cancers, could decrease intraoperative bleeding and postoperative complications, and accelerate the speed of intestinal function recovery.

Minimally invasive surgery is safe and effective for advanced HCC patients receiving perioperative adjuvant therapy: a real-world retrospective study

BackgroundCombining surgery and perioperative adjuvant therapy, including tyrosine kinase inhibitors (TKI), anti-PD-1 antibody, and interventional therapy, can prolong the survival of patients with advanced hepatocellular carcinoma (HCC). Adverse reactions to adjuvant therapy, surgical trauma, and surgical complications are challenging for this combined treatment mode. This study aims to explore whether minimally invasive hepatectomy is safe or appropriate in patients with advanced HCC.MethodsThis retrospective study involved patients with advanced HCC who underwent minimally invasive surgery (MIS group, n = 31) or open surgery (OS group, n = 35) from August 2020 to April 2023 from four medical groups at two medical centers. Operation-related indicators, early postoperative complications, and postoperative drug tolerance were compared between the two groups.ResultsSixty-six patients were enrolled. Between the MIS group and the OS group, there were no significant differences in Barcelona Clinic Liver Cancer (BCLC) tumor staging (P = 0.44), surgical difficulty (P = 0.29), and R0 resection rate (P = 0.34). Compared with the OS group, the MIS group had less blood loss (101.9 mL vs. 209.0 mL, P = 0.003), shorter average operation time (165.7 min vs. 224.5 min, P = 0.000 4), shorter postoperative fasting time (1.5 d vs. 2.4 d, P = 0.002), shorter postoperative bed time (1.7 d vs. 3.0 d, P < 0.0001) and length of hospital stay (7.1 d vs. 9.4 d, P = 0.001), lower incidence of complication (Clavien-Dindo grade II–III, P = 0.03), better nutritional status, and earlier postoperative adjuvant treatment.ConclusionMinimally invasive hepatectomy is safe for patients with advanced HCC after conversion therapy and may improve tolerance to combination treatment relative to open surgery.Graphical

Evaluation of post-operative complications and adjuvant treatments following immediate prepectoral versus subpectoral direct-to-implant breast reconstruction without acellular dermal matrix

BackgroundIn immediate breast reconstruction (IBR), it is unclear whether there is any difference in the complication rates between prepectoral versus subpectoral implant placement without acellular dermal matrix (ADM). AimTo compare the rates of early post-operative complications and time to initiation of adjuvant treatment in patients undergoing IBR between prepectoral and subpectoral implant placement without ADM for the two surgical procedure. MethodsWe retrospectively retrieved data of patients who underwent IBR with prepectoral versus subpectoral implant placement between January 1, 2020 and December 31, 2022 in a large cancer center in France. ResultsWe included 192 patients: 119 in the prepectoral and 73 in the subpectoral group. Their clinical characteristics were similar. Thirty patients (15.6%) received adjuvant chemotherapy, among them 27 (14.1%) received it within 12 weeks, and there was no difference between the groups (p = 0.12). In the prepectoral group, 39 patients (32.8%) received adjuvant radiotherapy versus 5 (6.8%) in the subpectoral group (p < 0.001), but there was no significant difference in time to treatment commencement. Overall, 35 patients (29.4%) in the prepectoral group and 17 (23.3%) in the subpectoral group experienced post-operative complications (p = 0.44). Using multivariable analysis, the only factor associated with post-operative complications was determined to be mastectomy weight (odds ratio 1.98 (1.10–3.59) for weight ≥500 g; p = 0.02). ConclusionPrepectoral implant placement without ADM can be proposed to patients undergoing IBR with an indication for adjuvant treatment. However, in our study, the reoperation rate with this technique was slightly higher (p = 0.008). This is partly due to the learning curve for surgeons using this new technique.

Early safety outcomes of laparoscopic one anastomosis gastric bypass in patients with class III, IV, and V obesity.

The extremely obese patient deserves special consideration: significant comorbidities, technical difficulties, and increased postoperative morbidity and mortality are all expected in this patient population. The study compared early postoperative complications (≤30-day) following one-anastomosis gastric bypass (OAGB) morbidity in patients with morbid obesity class IV obesity, body mass index (BMI) ≥50-59.9kg/m2, and class V obesity, BMI ≥60 patients. We retrospectively reviewed perioperative OAGB outcomes in three BMI groups. Operative time, length of stay (LOS), and overall early postoperative complication rates were studied. Patient-reported complications were ranked by Clavien-Dindo Classification (CDC). Between January 2017-December 2021, consecutive patients with obesity class III (n=2950), IV (n=256), and V (n=23) underwent OAGB. BMI groups were comparable in sex, age, and associated comorbidities. Mean operative time was significantly longer in the higher BMI groups: class III (66.5±25.6min), IV (70.5±28.7min), and V (80.0±34.7min), respectively (p=0.018); no difference in LOS. In respective BMI classes, ≤30-day complication rates were 3.2%, 3.5%, and 4.3% (p=0.926). The respective number of patients with CDC grades of one to two were 45 (1.5%), 6 (2.3%), and 1 (4.3%), p=0.500; and in grade ≥3a, 25 (0.8%), 1 (0.4%), 0 (0.0%), p=0.669. There was 0.06% mortality (n=2 in 3229), both in BMI class III. OAGB is a safe BS procedure in patients with class III, IV, and V obesity in the perioperative term with comparable ≤30-day morbidity in the three BMI groups.

Elevated Hb A1C level and revisional bariatric surgery complications

BackgroundElevated Hb A1C is a modifiable risk factor for postoperative complications. However, in bariatric surgery, as published by our group and others, elevated preoperative Hb A1C may not be associated with increased postoperative complications. Previous literature has focused on primary bariatric surgery and has excluded the higher-risk revisional surgery cohort. ObjectiveTo assess the impact of Hb A1C on early postoperative outcomes in patients requiring revisional bariatric surgery. SettingMetabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. MethodsWe undertook a retrospective review of patients undergoing revisional bariatric surgery between 2017 and 2018 from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. Two groups were studied, defined by Hb A1C cutoff, ≤8% versus >8% and ≤10% versus >10%. Early postoperative complications were compared at each threshold, with the primary outcome defined as a composite of all complications. Propensity score matching (PSM) was used with one-to-one matching for covariates, and the complication rates before and after PSM were calculated and assessed by Fisher’s exact test and conditional logistic regression, respectively. ResultsA total of 16,234 patients had undergone revisional bariatric surgery. After PSM, elevated Hb A1C was not associated with worse outcomes. No significant difference was seen in the composite outcomes for Hb A1C ≤8% versus Hb A1C >8% (P = .22) or for patients with Hb A1C ≤10% versus Hb A1C >10% (P < .46). There were no differences in individual outcomes such as surgical-site infections, cardiopulmonary complications, or readmissions/reinterventions. ConclusionIn this study of revisional bariatric patients, elevated Hb A1C >8% or >10% was not associated with increased postoperative complications. Prospective studies are needed to investigate this further.

Premalignant cystic neoplasms and neuroendocrine tumors of the pancreatic head-Is the Kausch-Whipple resection an adequate treatment?

Currently, the most frequently used surgical treatment for symptomatic, benign, premalignant cystic and neuroendocrine neoplasms of the pancreatic head is the Whipple procedure or pylorus-preserving pancreatoduodenectomy (PD). However, when performed for treatment of benign tumors, PD is amultiorgan resection involving loss of pancreatic and extrapancreatic tissue and functions. PD for benign neoplasm is associated with the risk of considerable early postoperative complications and an in-hospital mortality of up to 5%. Following the Whipple procedure anew onset of diabetes mellitus is observed in 14-20% and new exocrine insufficiency in 25-45%, leading to metabolic dysfunction and impairment of quality of life persisting after resection of benign tumors. Symptomatic neoplasms are indication for surgery. Patients with asymptomatic pancreatic tumors are treated according to the criteria of surveillance protocols. The goal of surgical treatment for asymptomatic patients is, according to the guideline criteria, interruption of the surveillance program before the development of an advanced stage cancer associated with the neoplasm. Tumor enucleation and duodenum-preserving pancreatic head resection, either total or partial, are parenchyma-sparing resections for benign neoplasms of the pancreatic head. The first choice for small tumors is enucleation; however, enucleation is associated with an increased risk of pancreatic fistula B + C following pancreatic main duct injury. Duodenum-preserving total or partial pancreatic head resection has the advantage of low postoperative surgery-related complications, amortality of < 0.5% and maintenance of the endocrine and exocrine pancreatic functions. Parenchyma-sparing pancreatic head resections should replace classical Whipple procedures for neoplasms of the pancreatic head.

Impact of recipient and donor pretransplantation body mass index on early postosperative complications after lung transplantation

BackgroundPrior studies have assessed the impact of the pretransplantation recipient body mass index (BMI) on patient outcomes after lung transplantation (LT), but they have not specifically addressed early postoperative complications. Moreover, the impact of donor BMI on these complications has not been evaluated. The first aim of this study was to assess complications during hospitalization in the ICU after LT according to donor and recipient pretransplantation BMI.MethodsAll the recipients who underwent LT at Bichat Claude Bernard Hospital, Paris, between January 2016 and August 2022 were included in this observational retrospective monocentric study. Postoperative complications were analyzed according to recipient and donor BMIs. Univariate and multivariate analyses were also performed. The 90-day and one-year survival rates were studied. P < 0.05 was considered to indicate statistical significance. The Paris-North Hospitals Institutional Review Board approved the study.ResultsA total of 304 recipients were analyzed. Being underweight was observed in 41 (13%) recipients, a normal weight in 130 (43%) recipients, and being overweight/obese in 133 (44%) recipients. ECMO support during surgery was significantly more common in the overweight/obese group (p = 0.021), as were respiratory complications (primary graft dysfunction (PGD) (p = 0.006), grade 3 PDG (p = 0.018), neuroblocking agent administration (p = 0.008), prone positioning (p = 0.007)), and KDIGO 3 acute kidney injury (p = 0.036). However, pretransplantation overweight/obese status was not an independent risk factor for 90-day mortality. An overweight or obese donor was associated with a decreased PaO2/FiO2 ratio before organ donation (p < 0.001), without affecting morbidity or mortality after LT.ConclusionPretransplantation overweight/obesity in recipients is strongly associated with respiratory and renal complications during hospitalization in the ICU after LT.

202 The Role of Surgical Management for Prolactinoma in the Era of Dopaminergic Agonists: An International Multicenter Report

INTRODUCTION: Although first-line prolactinoma (PL) management typically involves dopamine agonists (DAs), the role of surgery as a primary therapeutic is being reconsidered given the undesirable side effects of long-term DAs. METHODS: Patients surgically treated for PL from January 2017 through December 2020 were identified. Preoperative characteristics and postoperative outcomes were assessed. Multivariate models adjusting for tumor characteristics and surgery complexity identified factors predictive of complications and long-term adverse outcomes. RESULTS: Among 272 patients identified (65.1% female), the mean age was 38.0 ± 14.3 years. Overall, 54.4% of PLs were macroadenomas. Most PLs were managed microscopically (69.9%) and fewer endoscopically (29.0%). Although 29.8% of patients experienced at least one early postoperative complication, most were minor (39.3%), with less being major complications (4.4%). The most common major complications were epistaxis and worsened vision. Most minor complications involved electrolyte/sodium dysregulation. Based on available data on follow-up, disease remission on long-term follow-up imaging was achieved in 94.8% of cases, and residual/recurrent tumor was seen in 19.3%. Reoperations were required for 2.9% of cases. Upon multivariate analysis, previous surgery was significantly predictive of intraoperative complications (6.14 OR, p &lt; 0.01) and major complications (14.12 OR, p &lt; 0.01). Previous pharmacotherapy (0.27 OR, p = 0.02) and cavernous sinus invasion (0.19 OR, p = 0.03) were significantly prohibitive against long-term endocrinological cure. Knosp classification was highly predictive of residual tumor or PL recurrence on 6-month follow-up imaging (4.60 OR, p &lt; 0.01). CONCLUSIONS: Our results evaluate a modern, multicenter, global series of patients treated for PL. This data serves as a benchmark to compare with DAs and demonstrates that surgery offers high rates of remission with low rates of complications and recurrence. It may be reasonable to consider surgery as an alternative to DAs.

Evaluation of risk factors for postoperative neurologic intensive care admission after brain tumor craniotomy: A single-center longitudinal study.

Perioperative variable parameters can be significant risk factors for postoperative intensive care unit (ICU) admission after elective craniotomy for intracranial neoplasm, as assessed by various scoring systems such as Cranio Score. This observational study evaluates the relationship between these factors and early postoperative neurological complications necessitating ICU admission. In total, 119 patients, aged 18 years and above, of either sex, American Society of Anesthesiologists (ASA) grades I-III, scheduled for elective craniotomy and tumor excision were included. The primary objective was to evaluate the relationship between perioperative risk factors and the incidence of early postoperative complications as a means of validation of the Cranio Score. The secondary outcomes studied were 30-day postoperative morbidity/mortality and the association with patient-related risk factors. Forty-five of 119 patients (37.82%) required postoperative ICU care with the mean duration of ICU stay being 1.92 ± 4.91 days. Tumor location (frontal/infratemporal region), preoperative deglutition disorder, Glasgow Coma Scale (GCS) less than 15, motor deficit, cerebellar deficit, midline shift >3 mm, mass effect, tumor size, use of blood products, lateral position, inotropic support, elevated systolic/mean arterial pressures, and duration of anesthesia/surgery were associated with a higher incidence of ICU care. Maximum (P = 0.035, AOR = 1.130) and minimum systolic arterial pressures (P = 0.022, Adjusted Odds Ratio (AOR) = 0.861) were the only independent risk factors. Cranio Score was found to be an accurate predictor of complications at a cut-off point of >10.52%. The preoperative motor deficit was the only independent risk factor associated with 30-day morbidity (AOR = 4.66). Perioperative hemodynamic effects are an independent predictor of postoperative ICU requirement. Further Cranio Score is shown to be a good scoring system for postoperative complications.

Extrapleural pneumonectomy for sarcoma: Outcomes of adult patients at a specialized center.

Extrapleural pneumonectomy (EPP) is a complex surgical procedure involving en-bloc resection of the parietal and visceral pleura, lung, pericardium, and ipsilateral diaphragm. Small case series of pleural-based sarcoma of predominantly pediatric patients suggest EPP may be a life-prolonging surgical option. We aimed to describe the characteristics and outcomes of adults who underwent EPP at a specialized sarcoma center. Clinicopathologic variables, surgical details, and follow-up information were extracted for patients undergoing EPP for pleural-based sarcoma between August 2017 and December 2020. Primary outcomes were event-free survival (EFS) and overall survival (OS) from the date of EPP. Secondary outcomes were disease-free interval (DFI) prior to EPP, and early and late postoperative complications. Eight patients were identified, seven with soft tissue sarcoma and one with bone sarcoma. Patients had either localized disease with a primary thoracic sarcoma, sarcoma recurrent to the thorax, or de novo metastatic disease. All patients underwent resection of their pleural-based sarcoma by an experienced cardiothoracic surgeon, and some patients had pre or postoperative treatment. The perioperative morbidity was comparable with previously published reports of EPP performed in mesothelioma patients. At median follow-up of 22.5 months, median EFS was 6.0 months and OS was 20.7 months. Six patients (75%) had disease recurrence; five (62.5%) died of progressive disease. Two patients (25%) had not recurred: one died of a radiation-related esophageal rupture, and one was alive with no evidence of disease at 37.0 months. Characteristics of those with the longest EFS included low-grade histology and achieving a metabolic response to preoperative chemotherapy. In adults with pleural-based sarcoma, EPP is rarely curative but appears to be a feasible salvage procedure when performed at specialized centers. Patient selection is critical with strong consideration given to multimodal therapy to optimize patient outcomes. In the absence of a confirmed response to neoadjuvant treatment, long term survival is poor and EPP should not be recommended.

Impact of preoperative infection on the outcomes of liver transplant recipients: a national propensity score-matched retrospective cohort study in China.

Impact of preoperative infection on liver transplantation (LT) needs further investigation. From January 1, 2015 to December 31, 2022, 24,122 eligible patients receiving LT were enrolled from the China Liver Transplant Registry database. The outcomes of LT were compared after using the propensity score-matched analysis. Compared to the non-infection group, patients in the infection group were more likely to have postoperative effusion, infection, abdominal bleeding and biliary complications (all P<0.01), and they had shorter 30-day, 90-day survival and overall survival (OS) (all P<0.01). Cox proportional hazards regression analysis revealed that MELD score and cold ischemia time were risk factors for the OS in the infection group (both P<0.05). Besides, compared to the non-pulmonary group, patients in the pulmonary group were more likely to have postoperative effusion and infection (both P<0.0001), and less likely to have postoperative abscess and early allograft dysfunction (both P<0.05). Patients in the non-abdominal group also had a higher proportion of postoperative infection than those in the abdominal group (P<0.05). Furthermore, compared to the number=1 group, patients in the number≥2 group were more prone to postoperative effusion and infection (both P<0.01), and they also had shorter 30-day and 90-day survival (both P<0.05). Preoperative infection can result in a higher incidence of early postoperative complications and shorter survival in liver transplant recipients. The types and number of infection sites will also influence the prognosis of liver transplant recipients.

Pelvic Exenteration - Past, Present and Future.

Background: Bearing in mind that the open procedure is already validated by multiple studies, the article aims to prove that pelvic exenteration performed in a minimally invasive fashion might offer better survival and to potentially identify prognostic factors for the outcome of these patients. Material and Methods: Data regarding past and present classifications and surgical indications are presented. Patient data were collected retrospectively. Results: The most frequent diseases treated with pelvic exenteration, in terms of the hystological type, were gynecological malignancy and squamous cell carcinoma. Recurrent pelvic disease was found in 68.2% of patients. R0 resection was achieved in 72.7% of patients in the MI group, and in 73.7% of patients in the OP group. Peri-operative morbidity was reported to be 56.6% for open surgery, and 18.1% for minimally invasive. Average DFS was 20.15 months, ranging from 1.5 to 70.3 months, while the OS was calculated to be 38.1 months (0.33 1508) up until November 2023. Conclusion: Pelvic exenteration is a continuously improving surgical procedure, open approach being favored to minimally invasive one. On the other hand, hospitalization and morbidity are reduced when choosing the latter. R0 and lymph node status are important predictors for overall survival, as well as major early postoperative complications. All in all, pelvic exenteration is still a promising surgical procedure to extend cancer patients lives.

Compare the surgical outcome of Fistulectomy and Mucoal advancement flap in perianal fistula.

Objective: To compare the fistulectomy with mucosal advancement flap in treatment of perianal fistula in terms of mean hospital stay, frequency of anal incontinence and wound healing time. Study Design: Randomized Control Trial. Setting: Surgical OPD, DHQ and Allied Hospital, Faisalabad. Period: 1st March 2019 to 28 February 2020. Methods: Conducted on 120 (60 in each group) patients with fistula in ano presenting. Sampling technique was Non probability consecutive sampling. All the Patient age ranges from 20-55 years of either gender having perianal fistula which are low lying fistulas and with single external opening are included in study. Patients having perianal abscess, pilonidal sinus, Inflammatory bowel disease (Crohn’s disease, Ulcerative colitis) or with history of tuberculosis, HIV disease, Complex high lying fistulas with multiple external openings are excluded. Results: In our study, group A underwent fistulectomy while on group B we perform mucosal advancement flap. About 56.67%(n=34) in Group A and 50%(n=30) in Group B were between 20-40 years of age while 43.33%(n=26) in Group A and 50%(n=30) in Group B were between 41-55 years of age, mean+SD was calculated as 38.78+9.07 years and 40.12+8.89 years respectively. According to gender division 86.67%(n=52) in Group A and 78.33%(n=47) in Group B were male while 13.33%(n=8) in Group A and 21.67%(n=13) in Group B were females, mean hospital stay was calculated as 93.93+4.56 hours in Group A and 107.95+4.66 hours in Group B, p value was calculated as 0.0001 showing a significant difference between the two groups. Comparison of anal incontinence in both groups was done showing that 13.33% (n=8) in Group A and 23.33%(n=14) in Group B had anal incontinence, p value was calculated as 0.15. At one month postoperative follow-up only 4 patient (6.7%) in group A showed complete wound healing while in group B 28 patients out of 60(46.6%)showed complete wound healing, P value was calculated as 0.00167 showing a significant difference while there is no significant difference in incidence of early post-operative complications. Conclusion: We concluded that hospital stay was significantly decreased in cases with fistulectomy when compared with MAF while there was no significant difference regarding anal incontinence in both groups.

Analysis of 5,070 consecutive pedicle screws placed utilizing robotically assisted surgical navigation in 334 patients by experienced pediatric spine deformity surgeons: surgical safety and early perioperative complications in pediatric posterior spinal fusion.

This study evaluates the intraoperative and short-term complications associated with robotically assisted pedicle screw placement in pediatric posterior spinal fusion (PSF) from three surgeons at two different institutions. We retrospectively reviewed 334 pediatric patients who underwent PSF with robotic-assisted navigation at 2 institutions over 3 years (2020-2022). Five thousand seventy robotically placed screws were evaluated. Data collection focused on intraoperative and early postoperative complications with minimum 30-day follow-up. Patients undergoing revision procedures were excluded. Intraoperative complications included 1 durotomy, 6 patients with neuromonitoring alerts not related to screw placement, and 62 screws (1.2%) with documented pedicle breaches, all of which were revised at time of surgery. By quartile, pedicle breaches statistically declined from first quartile to fourth quartile (1.8% vs. 0.56%, p < 0.05). No breach was associated with neuromonitoring changes or neurological sequelae. No spinal cord or vascular injuries occurred. Seventeen postoperative complications occurred in eleven (3.3%) of patients. There were five (1.5%) patients with unplanned return to the operating room. Robotically assisted pedicle screw placement was safely and reliably performed on pediatric spinal deformity by three surgeons across two centers, demonstrating an acceptable safety profile and low incidence of unplanned return to the operating room.

Surgical rehabilitation of patients with Crohn’s disease

Objective — to enhance the outcomes of surgical rehabilitation for patients with Crohn’s disease through the improvement and implementation of organisational measures as well as general and specialised surgical strategies.&#x0D; Materials and methods. The study focused on the development of organisational measures as well as general and specialised surgical rehabilitation procedures for Crohn’s disease. The research was conducted to determine the scope of radical surgical interventions for complications resulting from segmental lesions with extensive damage to the intestinal tract. The study also aimed to develop methods of restorative, reconstructive and restorative operations that would reduce the frequency of postoperative complications, disease recurrence, digestive disorders in the intestinal tract, malabsorption, and anal incontinence. Additionally, the study aimed to improve the functional outcomes and quality of life for operated patients.&#x0D; Results. A total of 53 patients with Crohn’s disease — 28 (52.8%) men and 25 (47.2%) women — were operated on using specially designed surgical rehabilitation techniques. The patients undergoing surgery ranged in age from 19 to 45. 32 (60.4%) patients had segmental resections, while 21 (39.6%) had extensive resections. 8 (15.1%) patients underwent restorative operations, while 40 (75.4%) had reconstructive operations. A lifelong ileostomy was formed in 5 (9.4%) patients. Postoperative complications were observed in 12 (22.6%) patients, and disease relapses in 5 (9.4%) patients. One (1.8%) patient died after surgery. Positive functional outcomes, including improved digestion in the intestinal tract, normal absorption, and preservation of anal retention, were noted following restorative and reconstructive‑restorative operations.&#x0D; Conclusions. Organisational measures as well as general and specialised surgical rehabilitation strategies for Crohn’s disease allowed for more effective diagnosis and treatment of postoperative complications, better prevention of disease recurrence, improved digestion in the intestinal tract, normalised absorption processes, and preservation of anal retention. Following the implementation of specially designed surgical rehabilitation techniques, 20.7% and 1.8% of patients experienced early and late postoperative complications, respectively. Additionally, there were occurrences of postoperative mortality in 1.8% of patients and relapses in 9.4%. Severe forms of reflux ileitis, postcolectomy syndrome, and secondary anal incontinence syndrome were not observed.&#x0D;

Comparative evaluation of robot-assisted, laparoscopic and open surgical interventions in the combined treatment of stomach cancer

Introduction. Gastric cancer ranks fifth in incidence and fourth in mortality among all oncological diseases worldwide. According to recent clinical data, for stage cT2N0 and beyond, a combined approach using various schemes and regimens of anticancer drug therapy is recommended. Currently, indications for the use of minimally invasive techniques in the surgical treatment of locally advanced gastric cancer are not defined. Research objective. Comparative assessment of the immediate outcomes of robot-assisted, laparoscopic, and open surgical interventions in patients with gastric cancer of different localizations who underwent neoadjuvant polychemotherapy. Materials and methods. The study is based on a retrospective analysis of 81 medical histories of patients with locally advanced gastric cancer of different localizations operated on from 2018 to 2022 in the Department of Abdominal Oncology of City Hospital №40 in St. Petersburg. All patients underwent preoperative cycles of anticancer drug treatment within perioperative polychemotherapy schemes: FLOT – 64 (79%) patients, mFOLFOX6 – 9 (11.1%) patients, and FLOT+Тrastuzumab – 8 (9.9%) patients. Laparoscopic, traditional open, and robot-assisted surgical interventions were performed using the da Vinci surgical system. Results. Thirty-seven (45.7%) robot-assisted operations were performed, (22/27.2% – distal subtotal resections of the stomach (DSRS), 15/18.5% – gastrectomies (GE), 19 (23.5%) laparoscopic (11/13.6% – LDSRS, 8/9.9% – LGE), and 25 (30.9%) operations via laparotomy (9/11.1% – DSRS, 16/19.7% – GE). All patients underwent D2 and D2+ lymphadenectomy. Statistically significant differences were noted in groups for parameters such as operative intervention time, intraoperative blood loss, and length of hospital stay. Open surgical intervention group had significantly higher blood loss volume – median 275 (90.00; 300) ml (p&lt;0.001) and postoperative hospital stay duration – median 10.00 (9.00–14.00) days (p=0.017). Operation time was significantly shorter compared to minimally invasive interventions – median 150.00 (97.50–210.00) minutes for distal resections and 150.00 (96.25–207.50) minutes for GE (p&lt;0.005). There were no statistically significant differences in complication rates (p&gt;0.05) and the number of removed lymph nodes (p=0.334). However, the percentage of early postoperative complications, including lethal outcomes, was higher in the open intervention group (n=4/16%) compared to laparoscopic (n=2/10.5%) and robot-assisted (n=2/5.4%). The overall frequency of postoperative complications IIIA–V according to the Clavien-Dindo classification was 9.9%. One (1.2%) case had a lethal outcome after open gastrectomy. Histological examination showed no tumor growth in the resection margins (R0) for all patients. Complete regression of the gastric tumor (CAP-0) was noted in one case (1.23%) after combined treatment. Nearly complete response to therapy was observed in 13 cases (16%) (CAP-1), partial response in 28 cases (34.6%) (CAP-2), and no response to neoadjuvant therapy in 39 cases (48.1%) (CAP-3). Conclusions. Minimally invasive surgical interventions in the combined treatment of locally advanced gastric cancer are feasible, safe, and oncologically justified. Robot-assisted surgery demonstrates advantages over open and laparoscopic surgery in parameters such as intraoperative blood loss, number of removed lymph nodes, activation and hospitalization periods.

Retrospective Comparison of Postoperative Complications of Different Types of Urethroplasty in Patients with Long Urethral Strictures and Obliterations

.The objective: is to evaluate postoperative complications after various types of urethroplasty. Material and methods. The clinical data of the medical histories of 176 patients with long urethral strictures and obliterations were retrospectively assessed. Regarding the types of surgical operations, patients were divided into 3 groups: 1 group – buccal plastic urethra (BPU) – 93 (52.8%), 2 group – urethro-urethro- or urethro-prostate anastomosis (UUA) – 67 (39.8%), 3 group – replacement plastic surgery with a skin-fascial flap (PSF) – 16 (9.1%). In the postoperative period, the presence of early and late postoperative complications was assessed. Complications were evaluated according to the Clavien-Dindo scale. According to this classification, 3 groups were formed: group A – patients without complications or with class I complications – 110 (62.5%), group B – patients with postoperative complications II–IIIa according to the Clavien-Dindo classification – 36 (20.5%), group C – men with class IIIb-IV complications – 30 (17.0%). There were no class V complications after surgery. Results. When evaluating the length of urethral strictures and obliterations of patients of group A, it ranged from 2 to 7 cm in 46 (41.8%) cases, and in 59 patients the strictures were longer than 7 cm, in 5 (4.5%) patients the length was less than 2 cm. In all three groups, the majority of strictures were more than 2 cm: in group B, 50% of strictures were from 2 to 7 cm, and in 44.4% more than 7 cm. In group C, 16 patients (53.3%) the strictures were more than 7 cm long. But when comparing the average length of the urethral stricture between the groups, a significant difference is observed between group A and group B, as well as between group A and group C. In group A, according to the type of surgical treatment performed, most patients were divided into 41 (37.3%) UUA and 59 (53.6%) BPU among all patients who underwent surgical interventions. There were 10 (9.1%) group A patients after PSHFL. Group B patients with class II-IIIa complications were more numerous after BPU – 24 (66.7%), 10 (27.8%) patients were after UUA, and 2 (5.5%) patients were after PSHFL. When evaluating the difficulty of urethral strictures, the highest score was found in group C of patients 8.6±1.4, in group B it was slightly lower at 8.3±1.7 points. In group A, the complication score was lower and was 7.1±2.2, indicating that most of the urethral strictures in our study were complicated. There is a probable difference between groups A and B, and groups B and C. Conclusions. Statistically significant risk factors for the occurrence of postoperative complications are length, the presence of 2–3 degrees of spongiofibrosis, the complexity of stricture/obliteration of the urethra.

The utility of Martius fat pad in the repair of urogenital fistulae: review of current evidence.

To present the contemporary evidence on transvaginal urogenital fistulae (UGF) repair withMartius fat pad (MFP), compared to direct graftless fistula repair. We reviewed all available studies reporting lower UGF repair via the transvaginal approach in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). The primary outcome of interest was the fistula closure rates. When available, patients' baseline characteristics, indications for surgery, and early and late postoperative complications with focus on MFP-related complications are reported. In obstetric fistulae, tissue interposition has been almost completely abandoned, with contemporary large series reporting closure rates of >90% with graftless repair, even for complex fistulae. Similarly, most simple, non-irradiated iatrogenic fistulae can be closed safely without or with tissue interposition with success rates ranging between 86% and 100%. However, MFP is valuable in fistulae with difficulty achieving tension-free and layered closure, with significant tissue loss, urethral involvement and with poorly vascularised tissues after radiotherapy, with reported success rates between 80% and 97% in those challenging situations. A UGF repair should be individualised after considering the specific characteristics and complexity of the procedure. MFP interposition is probably unnecessary for the majority of low (obstetric) fistulae within otherwise healthy tissues. However, MFP may still have a place to maximise outcomes in low-income settings, in select cases with higher (iatrogenic) fistulae, and in most cases with radiotherapy.

Elevated alkaline phosphatase independently predicts early postoperative complications in noninfectious revision total shoulder arthroplasty.

This study investigates the association between preoperative serum alkaline phosphatase levels and 30day postoperative complications following noninfectious revision total shoulder arthroplasty (TSA). We hypothesize that elevated alkaline phosphatase levels are significantly associated with an increased 30day postoperative complication rate. The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent noninfectious revision TSA from 2015 to 2022. The study population was divided into two groups based on preoperative serum alkaline phosphatase: normal (44-147 IU/L) and elevated (> 147 IU/L). Logistic regression analysis was conducted to investigate the relationship between elevated alkaline phosphatase levels and postoperative complications. Compared to normal levels, elevated alkaline phosphatase was independently associated with a significantly greater likelihood of experiencing any complications (odds ratio [OR] 2.54, 95% confidence interval [CI] 1.41-4.55; P = .002), sepsis (OR 9.96, 95% CI 1.67-59.29; P = .012), blood transfusions (OR 3.77, 95% CI 1.48-9.61; P = .005), readmission (OR 3.65, 95% CI 1.48-9.01; P = .005), and length of stay > 2days (OR 2.37, 95% CI 1.31-4.30; P = .004). Elevated preoperative alkaline phosphatase was associated with a greater rate of early postoperative complications following noninfectious revision TSA.
