Woven EndoBridge Device Migration and Microsnare Retrieval Strategy: Single Institutional Case Reports with Technical Video Demonstration.

The Woven EndoBridge (WEB) (MicroVention/Terumo) device is a treatment option for wideneck bifurcation aneurysms. An uncommon adverse effect is WEB device migration. While certain bailout strategies for WEB recovery have been described, there is still a paucity of information on optimal strategies to maximize both short and long-term post-operative outcomes. We add 2 cases at our institution to the existing literature of WEBectomy in the setting of complicated intracranial aneurysm treatment. We discuss the long-term imaging outcomes with additional fluoroscopy video demonstrating our technique. Our findings reflect a clear benefit for the use of the Amplatz GooseneckTM microsnare (Medtronic) device as a means of WEB recovery, coupled with potential stent-assisted WEB embolization to remove the aneurysm from the parent circulation, while minimizing recurrence and thromboembolic complications.

Valve-in-valve/valve-in-ring transcatheter mitral valve implantation vs. redo surgical mitral valve replacement for patients with failed bioprosthetic valves or annuloplasty rings: A systematic review and meta-analysis

BackgroundValve-in-valve (ViV)/valve-in-ring (ViR) transcatheter mitral valve implantation (TMVI) is a less invasive alternative to redo surgical mitral valve replacement (SMVR). To further verify its feasibility, we aimed to appraise early clinical outcomes after either ViV/ViR TMVI or redo SMVR for failed bioprosthetic valves or annuloplasty rings, as a comparison of long-term follow-up results are not available for these procedures. MethodsWe systematically searched PubMed, Cochrane Controlled Trials Register, EMBASE, and Web of Science to identify studies that compared ViV/ViR TMVI and redo SMVR. Fixed- and random-effects meta-analyses were used to compare the early clinical results between these two groups. ResultsA total of 3,890 studies published from 2015 to 2022 were searched, and ten articles comprising 7,643 patients (ViV/ViR TMVI, 1,719 patients; redo SMVR, 5,924 patients) were included. In this meta-analysis, ViV/ViR TMVI significantly improved in-hospital mortality (fixed-effects model: odds ratio [OR], 0.72; 95% confidence interval [CI], 0.57–0.92; P = 0.008) and for the matched populations (fixed-effects model: OR, 0.42; 95% CI, 0.29–0.61; P < 0.00001). ViV/ViR TMVI also outperformed redo SMVR in 30-day mortality and in rates of early postoperative complications. ViV/ViR TMVI resulted in less time spent in the ICU and hospital, whereas it showed no significant difference in one-year mortality. A lack of comparison of long-term clinical outcomes and postoperative echocardiographic results are important limitations of our results. ConclusionsViV/ViR TMVI is a reliable alternative to redo SMVR for failed bioprosthetic valves or annuloplasty rings as a result of lower in-hospital mortality, higher 30-day survival, and lower early postoperative complication rates, although there is no significant difference in 1-year mortality.

Frontofacial Features of Unilateral Lambdoid Craniosynostosis: A Multicenter Assessment

Background: Unilateral lambdoid craniosynostosis is differentiated from deformational plagiocephaly primarily by assessing the cranium from posterior and bird’s-eye views. Findings include posterior displacement of the ipsilateral ear, ipsilateral occipitomastoid bossing, ipsilateral occipitoparietal flattening, contralateral parietal bossing, and contralateral frontal bossing. Diagnosis based off facial morphology may be an easier approach because the face is less obstructed by hair and head-coverings, and can easily be assessed when supine. However, frontofacial characteristics of unilateral lambdoid craniosynostosis are not well described. Methods: A retrospective cohort review of patients with isolated, unilateral lambdoid craniosynostosis from the Children’s Hospital of Pittsburgh and the Children’s Hospital of Philadelphia was performed. Preoperative frontal and profile photographs were reviewed for salient characteristics. Results: Nineteen patients met inclusion criteria. Eleven patients had left lambdoid craniosynostosis, and eight had right lambdoid craniosynostosis. All patients were nonsyndromic. Patients demonstrated contralateral parietal bossing and greater visibility of the ipsilateral ear. Contralateral frontal bossing was mild. The orbits were tall and turricephaly was present in varying severity. Facial scoliosis as a C-shaped deformity was present in varying severity. The nasal root and chin pointed to the contralateral side. Conclusions: The combination of greater visibility of the ipsilateral ear, contralateral parietal bossing, and C-shaped convex ipsilateral facial scoliosis are hallmark frontofacial features of unilateral lambdoid craniosynostosis. Although the ipsilateral ear is more posterior, the greater visibility may be attributed to lateral displacement from the mastoid bulge. Evaluation of long-term postoperative results is needed to assess if this pathognomonic facial morphology is corrected following posterior vault reconstruction.

Skeletal muscle mass and quality before preoperative chemotherapy influence postoperative long-term outcomes in esophageal squamous cell carcinoma patients

Infinitesimal Periangular Pterygomasseteric Transectioning Approach for the Base Fractures of the Mandibular Condyle: A Technical Note and Quality of Life Outcome.

Purpose Infinitesimal Periangular Pterygomasseteric Transectioning Approach (IPPTA) is a minimal access surgical approach utilized for the management of base fractures of the mandibular condyle. The aim of the study was to evaluate and report the long-term post-operative functional outcomeusing this surgical access approach. Materials and method A prospective clinical study involving 20 patients was undertaken to evaluate the post-operative functional and aesthetic outcome for the patients that underwent surgery for base fractures of the mandibular condyle using IPPTA. The various parameters assessed were wound healing, marginal mandibular nerve injury, diet intake, mandibular function, and any other complications at twelfth post-operative month. Results IPPTA provided adequate exposure to the condylar base fracture for open reduction and internal fixation (ORIF) and was found to have an uneventful post-operative recovery phase in terms of functional and aesthetic outcomes. Conclusion IPPTA involves utilizing a smaller incision and provides adequate exposure to the condylar base region for ORIF to establish a satisfactory form and function with a predictable outcome.

The Impact of Preoperative Sagittal Imbalance on Long-term Postoperative Outcomes Following Minimally Invasive Laminectomy

Background: Postoperative sagittal alignment has been shown to be associated with patient-reported outcome measures (PROMs) following open lumbar decompression procedures, although it is unknown whether preoperative sagittal imbalance affects clinical outcomes of minimally invasive surgical (MIS) decompression only surgery. Purpose: We sought to evaluate the impact of preoperative pelvic incidence-lumbar lordosis (PI-LL) imbalance on PROMs after MIS laminectomy for the treatment of neurogenic claudication symptoms. Methods: We conducted a retrospective cohort study of adult patients undergoing MIS laminectomy for degenerative lumbar spinal stenosis between April 2017 and April 2021 at a single institution. Of the 52 patients included (mean follow-up, 17 months) radiographs were taken prior to surgery and assessed for sagittal alignment parameters. Patients were grouped based on the preoperative PI-LL (balanced vs unbalanced). Changes in PROMs were compared between unbalanced PI-LL and balanced PI-LL groups. Minimal clinically important difference (MCID) for Oswestry Disability Index (ODI) was also assessed. Results: Of the 52 patients, 17 (32.7%) had unbalanced age-adjusted preoperative PI-LL. There was no significant difference found in PROMs between unbalanced and balanced PI-LL groups preoperatively or at final follow-up. Compared with those with unbalanced PI-LL, patients with balanced PI-LL were shown to have no added benefit in achieving MCID for ODI at long-term follow-up and no added benefit in the time to achieving MCID. Conclusion: These retrospective findings suggest that patients with unbalanced preoperative PI-LL may experience significant benefit in long-term clinical outcomes following MIS laminectomy, similarly to those with balanced PI-LL at baseline. The findings also suggest that the presence of sagittal imbalance preoperatively may not appreciably influence the long-term clinical outcomes following MIS laminectomy. Prospective study involving a larger population is warranted.

Clinical Impact of Ischemic Time of the Pancreas or Kidney Graft on Simultaneous Pancreas-Kidney Transplantation: A Single-Institution Study in Japan

Total ischemic time (TIT) potentially affects graft survival in organ transplantation. However, in simultaneous pancreas-kidney (SPK) transplantation, the impact of TIT of the pancreas (P-TIT) and kidney graft (K-TIT) on posttransplant outcomes remains unclear. This study investigated the impact of P-TIT and K-TIT on postoperative outcomes in patients after SPK at our institution in Japan. This study included 52 patients who underwent SPK at our hospital from April 2000 to March 2022. Of this patient group, the 52 patients were divided into a short P-TIT group (n=25), long P-TIT group (n=27), short K-TIT group (n=42), and long K-TIT group (n=10). Short- and long-term postoperative outcomes were compared between the groups. The long K-TIT group had a significantly higher rate of patients who did not urinate intraoperatively (50% vs 7%; P=.0007) and those requiring postoperative hemodialysis (80% vs 38%; P=.0169), as well as a significant longer duration of postoperative hemodialysis (97 ± 147 days vs 6 ± 9 days; P=.0016). These were not significantly different between the short and long P-TIT groups. Kidney or pancreas graft survival was not significantly different between the short and long P-TIT or K-TIT groups. Patients with prolonged K-TIT during SPK exhibited poor short-term outcomes, but no significant influence of K-TIT was identified on long-term outcomes. The P-TIT did not affect any significant outcomes. These results indicate that shortening K-TIT may improve short-term outcomes after SPK.

Nutrition of neonates and infants with severe congenital heart disease - the review of the literature

CHD is the most common birth defect with an incidence of 9 per 1,000 live births. The severity of the disease and the choice of treatment depend on the underlying anomaly. Despite advances in medical and surgical treatment that have led to more children with CHD reaching adulthood, disorders such as intestinal dysfunction, poor nutrition, and growth failure are still common in infants with CHD. Increased metabolic demand, decreased caloric intake, malabsorption, genetic factors, and fluid restriction can all result in an energy imbalance that negatively impacts morbidity and mortality in these patients. On the other hand, malnutrition is an important risk factor for adverse postoperative consequences. The state of nutrition affects growth and development, wound healing and the functioning of the immune system. Malnutrition affects both short-term and long-term postoperative outcomes. Recurrent infections caused by impaired immune system function and delayed healing of surgical wounds are considered short-term effects, while impaired growth, physical and cognitive development are seen as long-term effects. High postoperative mortality and morbidity, such as increased rates of hospitalization, delayed growth, prolonged recovery time, and longer hospital stays are associated with preoperative malnutrition. Appropriate nutrition protocols tailored to the requirements of patients with congenital heart disease help to improve short and long-term treatment outcomes. Nutritional and metabolic changes are age-dependent, and since this is a high-risk population, enteral and/or parenteral nutrition is difficult. Sources of increased metabolic demand in CHD include greater workload on the heart, pulmonary hypertension, and increased catecholamine secretion.

Bone-based versus soft-tissue free flaps in lower extremity reconstruction

BackgroundMost lower extremity defects and minor bone defect wounds requiring a free flap are treatable with soft-tissue flaps, whereas large bone defect wounds are treated with bone-based flaps. This study aimed to compare bone-based and soft-tissue-free flaps in terms of operative procedures and postoperative complications, including long-term outcomes of lower extremity reconstruction. MethodsThis two-center retrospective cohort study collected data from all lower-extremity reconstructions with free flaps performed between March 2014 and February 2022; the level of evidence is considered to be therapeutic level III. We investigated the operative procedure and postoperative complications classified as being related to either bone-based or soft-tissue flaps. The data were further classified into the trauma and non-trauma groups and the long-term postoperative outcomes of patients who were followed up for ≥12 months were analyzed. ResultsA total of 122 free flaps were included: 29 bone-based flaps (1 scapular and 28 fibular flaps) and 93 soft-tissue flaps (22 muscle-based and 71 fasciocutaneous flaps). There was no significant difference in postoperative complications, including long-term outcomes, between the free flap types, regardless of etiology. Vein grafts were used more often for bone-based flaps than for soft-tissue flaps (20.7% vs. 7.5%; p = 0.045). The donor veins of bone-based flaps were more often anastomosed to superficial veins than were those of soft-tissue flaps (37.9% vs. 10.8%; p < 0.001). ConclusionsUsing bone-based free flaps resulted in no significant differences in postoperative complications, including long-term outcomes, despite involving more complicated operative procedures than soft-tissue flaps. Thus, the use of vein grafts and anastomosis to the superficial venous system of the vascularized fibula graft may help avoid flap-related complications in bone-based free flaps.

Increasing obesity is associated with lower postoperative bleeding in coronary bypass patients

Despite inherent comorbidities, obese cardiac surgical patients paradoxically had shown lower morbidity and mortality, although the nature of this association is still unclear. Thus, the authors intended in this large registry-based study to investigate the impact of obesity on short- and long-term postoperative outcomes, focusing on bleeding and transfusion requirements. Retrospective registry study. Three university hospitals. A cohort of 12,330 prospectively compiled data from coronary bypass grafting patients undergoing surgery between 2007 to 2020 were retrieved from the Western Denmark Heart Registry. The parameters were analyzed to assess the association between body mass index (BMI) and the selected outcome parameters. The crude data showed a clear statistically significant association in postoperative drainage from 637 (418-1108) mL in underweight patients with BMI <18.5 kg/m2 to 427 (295-620) mL in severely obese patients with BMI ≥40 kg/m2 (p < 0.0001, Kruskal-Wallis). Further, 50.0% of patients with BMI <18.5 received an average of 451 mL/m2 in red blood cell transfusions, compared to 16.7% of patients with BMI >40 receiving 84 mL/m2. The obese groups were less often submitted to reexploration due to bleeding, and fewer received perioperative hemostatics, inotropes, and vasoconstrictors. The crude data showed increasing 30-day and 6-month mortality with lower BMI, whereas the one-year mortality showed a V-shaped pattern, but BMI had no independent impact on mortality in logistic regression analysis. Patients with high BMI may carry protection against postoperative bleeding after cardiac surgery, probably secondary to an inherent hypercoagulable state, whereas underweight patients carry a higher risk of bleeding and worse outcomes.

Orbital resection by intranasal technique (ORBIT): A new classification system for reporting endoscopically resectable primary benign orbital tumors.

The Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) staging system has become the gold standard for outcomes reporting in endoscopic orbital surgery for orbital cavernous hemangiomas (OCHs). A recent systematic review demonstrated similar outcomes between OCHs and other primary benign orbital tumors (PBOTs). Therefore, we hypothesized that a simplified and more comprehensive classification system could be developed to predict surgical outcomes of other PBOTs. Patient and tumor characteristics as well as surgical outcomes from 11 international centers were recorded. All tumors were retrospectively assigned an Orbital Resection by Intranasal Technique (ORBIT) class and stratified based on surgical approach as either exclusively endoscopic or combined (endoscopic and open). Outcomes based on approach were compared using chi-squared or Fisher's exact tests. The Cochrane-Armitage test for trend was used to analyze outcomes by class. Findings from 110 PBOTs from 110 patients (age 49.0±15.0 years, 51.9% female) were included in the analysis. Higher ORBIT class was associated with a lower likelihood of gross total resection (GTR). GTR was more likely to be achieved when an exclusively endoscopic approach was utilized (p<0.05). Tumors resected using a combined approach tended to be larger, to present with diplopia, and to have an immediate postoperative cranial nerve palsy (p<0.05). Endoscopic treatment of PBOTs is an effective approach, with favorable short-term and long-term postoperative outcomes as well as low rate of adverse events. The ORBIT classification system is an anatomic-based framework that effectively facilitates high-quality outcomes reporting for all PBOTs.

AVERAGE LONG-TERM OUTCOMES OF LAPAROSCOPIC INGUINAL HERNIA REPAIR

Objective: to determine the long-term postoperative outcomes of inguinal hernias using the TAPP approach with the internal ring suturing. Materials and methods. The design is a randomized multicentre clinical study. The study is based on a survey of 268 patients aged 18 to 84 years (mean age 59.2±10.6 years), including 46 (17.2%) women, 222 (82.8%) men with primary inguinal hernias. A total of 187 (69.8%) patients had a normal body mass index, 72 (26.9%) were overweight, 9 (3.3%) were obese. Interventions supposed the open techniques (Liechtenstein technique - 118 patients or Shouldice technique - 29 patients) and laparoscopic technique by TAPP approach (total 121), and specifically the modification with the internal ring suturing (12). The frequency and severity of chronic postoperative pain (up to 1 year) and the recurrence rate of inguinal hernia (up to 2 years) had been determined. Results.The incidence and severity of chronic pain syndromewas moderate and in most caseswere found to have no any intergroup significant differences. Single case showed the significant differences in incidence between open hernioplasty by Liechtenstein technique and TAPP (χ2 =4.241, p=0.040). The recurrence rate of hernias over the 2-year follow-up period was 3.0%. There were no significant differences whichever surgical method to be used. There was not any single case of relapse in the TAPP-IRS target group. The age of patients related to the most crucial risk factor; the intervention technique ranked number two. Account must be taken of the TAPP-IRS subgroup, where any recurrence not reported. The type of intervention had a minimal effect on the risk of recurrence, in particular due to interventions techniques restricted by open operations only. Conclusions. When performing open and laparoscopic hernioplasty for indirect inguinal hernia, the incidence and severity of postoperative pain after 1 month is lower with the laparoscopic method, and after 12 months it remits and has comparable characteristics. The TAPP-based internal ring suturing does not affect the postoperative pain syndrome. The recurrence rate of inguinal hernia after open and laparoscopic hernioplasty found to have no significant differences. When using TAPP-IRS, no relapses were reported.

Abstract P3-05-06: Prognostic impact of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis-related liver fibrosis on postoperative long-term outcomes of breast cancer

Abstract Background: Obesity, the modern ‘epidemic’, has shared correlation with fatty liver disease and breast cancer. However, previous studies on the relation between fatty liver and breast cancer have shown conflicting results on the impact of fatty liver on the survival and recurrence of breast cancer patients. And there was no attempt to find out the effect of liver fibrosis, which is the consequence of fatty liver disease, on female breast cancer patients. So we attempted to investigate the prognostic value of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis(NASH)-related liver fibrosis in patients with breast cancer undergoing surgery, using noninvasive tools like liver-to-spleen attenuation(L/S) ratio and Fibrosis-4(FIB-4) score, respectively. Methods: A total of 933 patients diagnosed with primary invasive breast cancer and receiving surgery at the university-affiliated referral center between April 2006 and December 2019 were included. After excluding patients who had significant alcohol consumption and hepatitis viral infection,838 patients were divided into two groups according to the L/S ratio of 1 measured by the preoperative low-dose computed tomography: 91 patients(10.9%) with a L/S ratio&amp;lt; 1 vs 747 patients(89.1%) with a L/S ratio≥1. They were also divided into two groups based on the FIB-4 score of 2.67: 804 patients (95.9%) with a FIB-4 score&amp;lt; 2.67 vs 34 patients (4.1%) with a FIB-4 score≥2.67. The Cox proportional hazards model was used to calculate the hazard ratio (HR) and the 95% confidence interval (CI). Results: Patients with NAFLD were older, had higher BMI, and had a higher proportion of mastectomy and hyper-transaminasemia. They showed worse overall, disease-free, and regional recurrence-free survivals compared to those without NAFLD (p=0.008, 0.043, and 0.017, respectively), but no significant differences in local recurrence-free, systemic recurrence-free, and contralateral breast cancer-free survivals. The survival outcome of breast cancer did not show any relationship with NASH-related liver fibrosis (overall survival; p=0.061, disease-free survival; p=0.557). NAFLD was a significant risk factor for mortality in multivariable analysis (HR, 2.077; 95% CI, 1.052–4.102; p=0.035). After stratifying for subtypes of breast cancer, the L/S ratio remained a significant predictor of overall, disease-free, local recurrence-free, and regional recurrence-free survivals in only the hormone receptor-positive/HER2−negative subtype (p=0.007, 0.005, 0.009, and &amp;lt; 0.001, respectively). Conclusion: NAFLD is significantly associated with decreased overall survival, disease-free survival and increased regional recurrence in patients with breast cancer especially the hormone receptor-positive/HER2−negative subtype. NASH-related fibrosis was not associated with survival. Therefore, NAFLD should be assessed in the preoperative setting for predicting long-term prognoses of breast cancer patients Citation Format: Hyunsu Yeoh, Siwon Jang, Jong-Ho Cheun, Jin Ah Kwon, Myoung Seok Lee, Bumjo Oh, In Sil Choi, Sohee Oh, Jongjin Kim, Jeong Hwan Park, Won Kim, Ki-Tae Hwang.

Short- and Long-Term Outcomes of the Minimal Proximal Resection Margin in Total Gastrectomy for Siewert II Adenocarcinoma of the Esophagogastric Junction.

This study aimed to investigate the feasibility of the minimal proximal resection margin (PRM) in total gastrectomy (TG) for Siewert II adenocarcinoma of the esophagogastric junction (AEG). This study finally included 178 Siewert II advanced AEG patients who underwent TG from January 2017 to September 2020. According to the PRM length, patients were divided into 20-25mm group and 30-35mm group. Intraoperative, short-, and long-term postoperative outcomes were compared between two groups. The PRM of the 20-25mm group had significantly less operation time compared with the PRM of the 30-35mm group (P < .001), but the amount of blood loss, management of the diaphragmatic crura, and the incidence of positive resection margin were not significantly different between two groups (P > .05). In short-term postoperative outcomes, first gas-passing time, gastric-tube removal time, start time of diet, hospitalization, postoperative complications, and body weight loss were similar between two groups (P > .05). During the follow-up, the 3-year overall survival rates and the recurrence rates were not significantly different between the PRM of 20-25mm and 30-35mm groups (81.2% vs 83.5%, P = .695; 18.8% vs 15.5%, P = .812, respectively). With less operation time and more preserved esophagus, the minimal PRM length of 20-25mm could be an appropriate option in TG for patients with Siewert II advanced AEG.

Principles and outcomes of gender-affirming vaginoplasty.

Vaginoplasty is the most frequently performed gender-affirming genital surgery for gender-diverse people with genital gender incongruence. The procedure is performed to create an aesthetic and functional vulva and vaginal canal that enables receptive intercourse, erogenous clitoral sensation and a downward-directed urine stream. Penile inversion vaginoplasty (PIV) is a single surgical procedure involving anatomical component rearrangement of the penis and scrotum that enables many patients to meet these anatomical goals. Other options include minimal-depth, peritoneal and intestinal vaginoplasty. Patient quality of life has been shown to improve drastically after vaginoplasty, but complication rates have been documented to be as high as 70%. Fortunately, most complications do not alter long-term postoperative clinical outcomes and can be managed without surgical intervention in the acute perioperative phase. However, major complications, such as rectal injury, rectovaginal fistula, and urethral or introital stenosis can substantially affect the patient experience. Innovations in surgical approaches and techniques have demonstrated promising early results for reducing complications and augmenting vaginal depth, but long-term data are scarce.

Simultaneous surgery for upper gastrointestinal cancer and cardiovascular diseases

To analyze the immediate and long-term results of simultaneous surgical treatment in patients with upper gastrointestinal cancer and cardiovascular diseases. There were 9 patients with upper gastrointestinal cancer and cardiovascular diseases who underwent simultaneous surgical treatment. We assessed safety and efficacy of this approach. Mean age of patients was 65.7±5.7 years. Coronary artery disease was diagnosed in 3 patients, aortic valve disease - 1 patient, abdominal aortic aneurysm - 2; 4 patients suffered from isolated mitral valve disease, stenosis of the left vertebral artery, internal and external carotid arteries and Leriche syndrome. Considering immediate and long-term postoperative results, we can emphasize advisability of simultaneous surgeries in appropriate patients.

Management and Morbidity of Major Pelvic Hemorrhage in Complex Abdominopelvic Surgery

Introduction: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management, and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdominopelvic surgery. Methods: Patients who had major intraoperative pelvic hemorrhage during complex abdominopelvic surgery at 11 tertiary referral centers between 1997 and 2017 were included. Patient characteristics, management strategies to control bleeding, short- and long-term postoperative outcomes were evaluated retrospectively. Results: There were 120 patients with a mean age of 56.6 ± 2.4 years and a mean BMI of 28.3 ± 1 kg/m². While 104 (95%) of the patients were operated for malignancy, 16 (5%) of the patients had surgery for a benign disease. The most common bleeding site was the presacral venous plexus 90 (75%). Major pelvic hemorrhage was managed simultaneously in 114 (95%) patients. Electrocauterization 27 (23%), pelvic packing 26 (22%), suturing 7 (6%), thumbtacks application 7 (6%), muscle welding 4 (4%), use of energy devices 2 (2%), and topical hemostatic agents 2 (2%) were the management tools. Combined techniques were used in 43 (36%) patients. Short-term morbidity and mortality rates were 48 (40%) and 2 (2%), respectively. High preoperative CRP levels (p = 0.04), history of preoperative radiotherapy (p = 0.04), longer bleeding time (p = 0.006), and increased blood transfusion (p = 0.005) were the factors associated with postoperative morbidity. Conclusion: Postoperative morbidity related to major pelvic hemorrhage can be reduced by optimizing the risk factors. Prehabilitation prior to surgery to moderate inflammatory status and prompt action with proper technique to control major pelvic hemorrhage can prevent excessive blood loss in complex abdominopelvic surgery.

Diagnostic Procedures and Surgical Treatment of Craniodorsal Coxofemoral Luxation in a dwarf rabbit

To our knowledge, there are no sufficient reports on the full management of hip luxation in rabbits, including descriptions of the diagnostics procedure with the use of computed tomography, surgical procedure, and postoperative management with a measurable assessment of the results. The objective of this study was to report on a computed tomography examination of a coxofemoral joint in a rabbit, a surgical technique for the repair of craniodorsal coxofemoral dislocation, as well as short- and long-term postoperative outcomes. Craniodorsal coxofemoral luxation was diagnosed by physical examination and radiographic examination. A craniodorsal luxation of the femoral head and the presence of an intact femoral neck were confirmed by computed tomography. An ostectomy of the femoral head and neck was performed using a craniolateral open approach. The coxofemoral luxation was successfully reduced, and reluxation did not occur. At short- and long-term follow-ups, in parallel with clinical examination, an extensive pain assessment protocol was applied. CT proved to be a simple and effective technique and should be considered as an alternative to radiographic examination for diagnosis of coxofemoral luxation in rabbits. An immediate surgical intervention in hip dislocation in rabbits is necessary to alleviate pain associated with the movement of the injured joint and to avoid development of degenerative changes. In follow-up examinations after the procedure, a reliable assessment of postoperative pain and the effectiveness of perioperative analgesia should be made by introducing a postoperative pain assessment protocol. It could simplify an objective comparison between outcomes of different orthopaedic procedures in rabbits.

Platelet to Lymphocyte Ratio as a Predictive Tool for the Perioperative and Postoperative Outcomes in Advanced Stage Ovarian Cancer.

Background: platelet to lymphocyte ratio remains a significant prognostic factor in different malignancies. The aim of the current paper is to study the correlation between the preoperative values of platelet to lymphocyte ratio (PLR) and the postoperative outcomes in ovarian cancer patients. Method: we conducted a retrospective study on 57 patients submitted to cytoreductive surgery between 2014-2020. We determined the optimal cut off value of PLR for predicting survival outcomes by using the Receiver Operating Characteristic curve a value of 350 being obtained. The patients were further classified in two groups according to the PLR value. Results: there were 37 patients with PLR 350 and respectively 20 patients with PLR 350. Patients in the second group were significantly older and presented significantly higher rates of perioperative complications, a significantly higher level of circulating platelets, of CA125 and respectively a significantly lower level of circulating lymphocytes and of preoperative hemoglobin level. Meanwhile, patients in the second group reported a significantly poorer disease free and overall survival. Conclusions: ovarian cancer patients with higher preoperative levels of PLR trend to have a poorer early and long-term postoperative outcome. Therefore, in such cases more aggressive systemic therapies might be needed.

Comparison of GLIM and PG-SGA for predicting clinical outcomes of patients with esophageal squamous carcinoma resection.

to determine the validity of the Global Leadership Initiative on Malnutrition (GLIM) against the Patient Generated-Subjective Global Assessment (PG-SGA) as a gold standard tool in malnutrition diagnosis, and to assess the impact of malnutrition diagnosed using GLIM and PG-SGA on the clinical outcomes of patients with esophageal squamous carcinoma (ESCC) resection. we prospectively analyzed 182 patients with ESCC who underwent radical esophagectomy. Preoperative malnutrition was diagnosed using GLIM and PG-SGA, and the postoperative clinical outcomes, including postoperative complications, postoperative chest tube indwelling time, length of stay and total hospitalization cost, were recorded. The association between the prevalence of malnutrition defined by the two tools and postoperative clinical outcomes was evaluated. among the 182 ESCC patients, the incidence of malnutrition before surgery was 58.2 % and 48.4 % defined by PG-SGA and GLIM, respectively. GLIM and PG-SGA had good consistency in nutritional assessment of ESCC patients (k = 0.628, p < 0.001). Malnourished patients had higher TNM stages and older ages (all p < 0.05). Patients with malnutrition as assessed by PG-SGA and GLIM had a higher incidence of postoperative complications, a longer indwelling time of chest tube after esophagectomy, longer hospital length of stay, and higher hospitalization costs than patients with good nutrition (p < 0.001). Comparing the predictive efficiency of postoperative complications, the sensitivity of PG-SGA- and GLIM-defined malnutrition were 81.6 % and 79.6 %, the specificity were 50.4 % and 63.2 %, the Youden index were 0.320 and 0.428, and the Kappa value were 0.110 and 0.130, respectively. The areas under ROC curve of PG-SGA- and GLIM-defined malnutrition and postoperative complications were 0.660 and 0.714, respectively. this study indicates the effectiveness of malnutrition diagnosed according to GLIM and PG-SGA in predicting postoperative clinical outcomes among patients with ESCC. Compared with PG-SGA, GLIM criteria can better predict postoperative complications of ESCC. Follow-up analysis of postoperative long-term survival is needed to explore the association between different assessment tools and postoperative long-term clinical outcomes.
