A Retrospective Study to Compare Patient Outcomes from Standard Total Knee Arthroplasty (TKA) versus Navigation-Guided Arthroplasty Using the Brainlab Software-Guided Surgical System at a Center in Hebei Province January 2021 to July 2023.

BACKGROUND This retrospective study aimed to compare patient outcomes from standard total knee arthroplasty (TKA) vs navigation-guided arthroplasty using the Brainlab software-guided surgical system at Cangzhou Hospital of Integrated TCM-WM, Hebei, Hebei Province, China from January 2021 to July 2023. MATERIAL AND METHODS A total of 239 patients who underwent total knee arthroplasty in Cangzhou Hospital of Integrated TCM-WM, Hebei from January 2021 to July 2023 were retrospectively analyzed. According to the inclusion criteria, 212 eligible patients were selected for analysis and divided into a Navigation Group (NG) (n=105) and a Traditional Group (TG) (n=107) according to surgical method used. Outcomes measured included duration of disease, operative time, intraoperative blood loss volume, postoperative length of hospital stay, and pain measured by the hospital for special surgery knee score (HSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and forgotten joint score (FJS). RESULTS The comparison of perioperative results between the 2 groups showed that the incision length in the NG was significantly longer than that in the TG (P<0.001, 95% Cl 2.59-3.35). At 3 months after surgery, the HSS score of the NG was statistically higher than that of the TG (P=0.002, 95% Cl 3.42-4.46); the WOMAC score of the NG was lower than that of the TG (P<0.001, 95% Cl -4.41-2.87); and the FJS score of the NG was significantly higher than that of the TG (P=0.003, 95% Cl 2.39-3.67). CONCLUSIONS Compared with conventional TKA, use of the Brainlab navigation system is associated with a longer incision, more accurate implantation position of the prosthesis, faster recovery of knee joint function, and helps patients to "forget" about their knee prosthesis in the short term.

Comparison of the clinical effects of dual-modality endoscopy and traditional laparotomy for the treatment of intra- and extrahepatic bile duct stones.

Bile duct stones (BDSs) may cause patients to develop liver cirrhosis or even liver cancer. Currently, the success rate of surgical treatment for intrahepatic and extrahepatic BDSs is not satisfactory, and there is a risk of postoperative complications. To compare the clinical effects of dual-modality endoscopy (duodenoscopy and laparoscopy) with those of traditional laparotomy in the treatment of intra- and extrahepatic BDSs. Ninety-five patients with intra- and extrahepatic BDSs who sought medical services at Wuhan No.1 Hospital between August 2019 and May 2023 were selected; 45 patients in the control group were treated by traditional laparotomy, and 50 patients in the research group were treated by dual-modality endoscopy. The following factors were collected for analysis: curative effects, safety (incision infection, biliary fistula, lung infection, hemobilia), surgical factors [surgery time, intraoperative blood loss (IBL) volume, gastrointestinal function recovery time, and length of hospital stay], serum inflammatory markers [tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8], and oxidative stress [glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), malondialdehyde (MDA), and advanced protein oxidation products (AOPPs)]. The analysis revealed markedly better efficacy (an obviously higher total effective rate) in the research group than in the control group. In addition, an evidently lower postoperative complication rate, shorter surgical duration, gastrointestinal function recovery time and hospital stay, and lower IBL volume were observed in the research group. Furthermore, the posttreatment serum inflammatory marker (TNF-α, IL-6, and IL-8) levels were significantly lower in the research group than in the control group. Compared with those in the control group, the posttreatment GSH-Px, SOD, MDA and AOPPs in the research group were equivalent to the pretreatment levels; for example, the GSH-Px and SOD levels were significantly higher, while the MDA and AOPP levels were lower. Dual-modality endoscopy therapy (duodenoscopy and laparoscopy) is more effective than traditional laparotomy in the treatment of intra- and extrahepatic BDSs and has a lower risk of postoperative complications; significantly shortened surgical time; shorter gastrointestinal function recovery time; shorter hospital stay; and lower intraoperative bleeding volume, while having a significant inhibitory effect on excessive serum inflammation and causing little postoperative oxidative stress.

Risk Factors of Open Surgery Conversion in Laparoscopic Partial Nephrectomy to Achieve Nephron Sparing.

We aimed to evaluate the risk factors for the conversion from laparoscopic partial nephrectomy (LPN) to open surgery to achieve partial nephrectomy (PN). Data from patients who underwent LPN between June 2020 and September 2023 were analyzed retrospectively. Patients in whom the PN procedure could be completed laparoscopically were recorded as the 'Fully Laparoscopic' (FL) group (n=97), and those converted to open surgery from laparoscopy were recorded as the 'Conversion to Open' (CTO) group (n=10). The demographic and pathologic variables were compared between groups. Regression analyses were used to define predictor factors, and receiver operating characteristic analysis was used to define the cut-off value of the surgical bleeding volume. Conversion to open surgery was found in 10/107 patients (9.3%). There was no statistical difference between groups in demographic and pathologic variables. Intraoperative blood loss volume, upper pole localized tumor, and posterior localized tumor were found to be statistically higher in the CTO group (p=0.001, p=0.001, and p=0.043, respectively). Furthermore, these factors were only found to be statistically significant predictors of conversion to open surgery in both univariate and multivariate regression analyses. 235cc was found to be the cut-off value of intraoperative blood loss volume for predicting conversion to open surgery (p=0.001). Using these predictive factors in clinical practice, treatment planning will lead to the possibility of starting the treatment directly with open surgery instead of minimally invasive options, and it may also provide a chance of being prepared for the possibility of conversion to open surgery peroperatively.

Prevalence of acute kidney injury following percutaneous nephrolithotomy.

The objective is to evaluate the prevalence of acute kidney injury (AKI) as an early complication of the percutaneous nephrolithotomy (PCNL) procedure. From May 2022 to October 2022, we conducted a retrospective study on patients undergoing PCNL procedures in two of the tertiary medical centers affiliated with Isfahan University of Medical Sciences. Patients' baseline characteristics, laboratory values, perioperative data, and stone features were documented. AKI was defined either as a ≥0.3 mg/dL increase in the serum creatinine level within 2 days, or a ≥1.5-fold increase in baseline serum creatinine level within 7 days after the operation. Laboratory values were measured 1 day before PCNL and daily thereafter until discharge. Patients were followed 1 week later to detect all of the possible cases of AKI. The final analysis was performed on 347 individuals. AKI developed in 16 (4.61%) cases. The two groups were comparable regarding age (P = 0.887), gender (P = 0.566), and underlying comorbidities including diabetes mellitus (P = 0.577) and hypertension (P = 0.383). The mean body mass index (BMI) (P < 0.001) and both frequency and severity of hydronephrosis (P < 0.001) were significantly different. A higher mean PCNL duration (P < 0.001), period of hospitalization (P < 0.001), and blood loss volume (P < 0.001) were observed in those who developed AKI. Overall, 56.3% (9) of patients in the AKI group and 2.7% (9) in the non-AKI group required the establishment of more than one access tract, during the procedure (P < 0.001). A lower preoperative hemoglobin level was observed in the AKI group (P < 0.001). Those with AKI had significantly larger stones (3.08 ± 0.46 vs. 2.41 ± 0.23 cm, P < 0.001) and higher Hounsfield units (P < 0.001). In addition, in the AKI group, most of the calculi (81.3%, 13) were of staghorn type, whereas in the non-AKI group, calculi were most frequently located in the middle calyx (30.2%, 100), (P < 0.001). The prevalence of post-PCNL AKI is approximately 4.61%. The mean BMI, preoperative hemoglobin level, PCNL duration, intraoperative blood loss volume, and hospitalization period were significantly higher among patients who developed AKI. Those with AKI had significantly larger stones with higher Hounsfield units and more frequently of staghorn type. The two groups were not statistically different regarding age, gender, and presence of comorbidities (hypertension and diabetes mellitus).

Comparative Evaluation of the Results of Radical Surgical Treatment of Patients with Muscle-Invasive Bladder Cancer

Malignant neoplasms of the bladder with invasion into the muscle layer of the organ wall (MIBC) are recognized as a highly aggressive pathology with a poorly predicted outcome, a high mortality rate, involving patients of any age without gender differences. Radical surgery’s in patients with MIBC has long and highly established itself as one of the main methods of treatment. However, the results of open surgical interventions are still accompanied by a high level of complications. The materials of medical literature (PubMed, CrossRef) for 2000–2023 were studied, with the issues of comparative evaluation of the results of surgical treatment of patients with MIBC, complications of the postoperative period. The search was conducted on the key phrases “bladder cancer”, “open cystectomy”, “robot-assisted cystectomy”, “cancer-specific survival”. The widespread introduction of video-endoscopic methods of treating patients with this disease into clinical practice has made it possible to speak about a decrease in the volume of intraoperative blood loss, the frequency of infectious complications of the wound and inpatient stay. The development of robot-assisted bladder surgery (RARC) demonstrates a number of advantages of using the daVinci robot in terms of reducing the number of postoperative complications during the traditional to study the 30–60–90-day follow-up periods. The issues of rehabilitation of patients after various methods of urine diversion, the medical-economic aspects for RARC in expert urological centers and the feasibility of the widespread introduction of this technique in medical institutions remain unclear. The coverage of these issues in the medical scientific literature is ambiguous, and therefore requires additional analysis.

Short-Term Outcomes of Simultaneous Inguinal Hernia Repair at Laparoscopic Appendectomy in Children: Cohort Study

Background. Nowadays, simultaneous techniques have been widely adopted in abdominal pediatric surgery as they allow to perform surgical interventions for several diseases at the same time. However, the safety of such interventions requires further studies. Objective. The aim of the study is to analyze the short-term outcomes of simultaneous hernia repair in laparoscopic appendectomy in children. Methods. The study included data from patients hospitalized with suspected acute appendicitis in 2022–2023. The study group included children operated for acute appendicitis and who had signs of patent processus vaginalis. Percutaneous internal ring suturing (PIRS) was performed in all cases. The control group (no indirect inguinal hernia was revealed) was formed by pairwise matching of patients by gender, age (± 1 year), and appendicitis type. The surgery time, the blood loss volume, the beginning of enteral feeding, and the presence of postoperative complications were analyzed. Results. The compared groups (13 individuals each) were comparable in gender (38% boys), age (median age about 10 years), and appendicitis type (catarrhal — 31%, phlegmonous — 38%, gangrenous — 31%), and white cell count at admission, presence of serous exudate and omentum changes revealed during surgery. The beginning of enteral feeding, the stool, as well as total duration of hospital stay after surgery did not differ in two groups. Moreover, both groups were comparable in terms of surgery duration, intraoperative blood loss volume, pain syndrome severity. No pyo-inflammatory complications of abdominal cavity or postoperative wounds were revealed during the hospital stay. Conclusion. Simultaneous hernia repair via PIRS method is effective and safe method of surgical management of pediatric patients with combination of acute appendicitis and inguinal hernia.

Effectiveness of the use of intravenous tranexamic acid and pericervical tourniquet in decreasing peri-operative blood loss following open abdominal myomectomy:A randomized controlled trial.

Uterine fibroid is the most common gynaecological tumour, with a prevalence of 20% to 50% of women over 30years.Abnormal uterine bleeding is one of the most common modes of presentation with menorrhagia. Open abdominal myomectomy is the most common treatment option in our environment. It is associated with a significant degree of blood loss, with consequent blood transfusion. Thus, the need for interventions to reduce blood loss during the procedure. This study assessed the effectiveness of intravenous tranexamic acid in reducing blood loss when used as an adjunct to peri-cervical tourniquet during open abdominal myomectomy. This study was conducted at Barau Dikko Teaching Hospital, Kaduna. It comprised thirty-six consenting patients scheduled for elective open abdominal myomectomy, randomly assigned to receive either intravenous tranexamic acid or placebo immediately after securing intravenous access in the theatre. All the patients had a peri-cervical tourniquet applied intraoperatively. The volume of intraoperative blood loss, blood transfusion rate and the total number of units transfused, haemodynamic changes associated with blood loss, and the complications associated with the use of tranexamic acid were evaluated during the first 72hours following the surgery. A total of thirty-six women who met the eligibility criteria were studied between June 2023 and December 2023. The mean age of the participants in the tranexamic acid group was 37.82 ± 5.89 years and 39.74 ± 5.17 years in the placebo group (p = 0.307). Most of the women 35 (97.2%) presented with symptoms of menorrhagia. Major blood loss > 1000 ml was recorded more among women in the placebo group than those who received tranexamic acid. There was a statistically significant reduction in the mean blood loss in the tranexamic acid group 947.65 ± 451.88 compared to 1320.53 ± 563.28. (p 0.037).There was an increase in the number of women who received a blood transfusion in the placebo group 7 (36.8%) compared to the tranexamic acid group 4 (23.5%) (p=0.387). Tranexamic acid resulted in a decrease in the risk of perioperative blood loss by 30%, RR 0.7 95% CI (2.19-2.59) and packed cell volume was significantly lower in the control group postoperatively (P value = .001). There was no significant side effect noticed in both groups. Tranexamic acid reduces blood loss during and after myomectomy for patients with uterine fibroids and the need for blood transfusion is reduced in patients who had intravenous tranexamic acid as an adjunct to the application of a tourniquet.

Comparison of laminoplasty and posterior segment fusion with laminoplasty and anterior segment fusion for treating acute extensional cervical spinal cord injury in pre-existing canal stenosis: a multicenter retrospective study

Background: Patients with pre-existing cervical spinal canal stenosis (CSCS) are more likely to suffer from an extensional spinal cord injury (SCI). However, the appropriate surgical alternatives for extended cervical SCIs in individuals with pre-existing CSCS remain unknown. The purpose of this study was to evaluate the clinical efficacies of laminoplasty and posterior short-segment fusion (PSF) with laminoplasty and anterior short-segment fusion (ASF) in the treatment of these patients. Methods: The clinical data of 258 patients from six spine centers were included in this retrospective study. Patients were divided into two different groups based on the surgical approach: laminoplasty and PSF (PSF group) and laminoplasty and ASF (ASF group). ASIA grades and JOA scores were obtained before and after surgery to assess neurological function. Results: There were 116 patients in the PSF group and 142 patients in the ASF group. The average operation time, intraoperative blood loss, and hospital stay were 188 min, 298 ml, and 7.6 days, respectively, in PSF group, compared to 245 min, 366 ml, and 10.4 days in PSF group, respectively. Complete decompression was achieved in all patients, and fusion was achieved 6 months after surgery. A post-operative computed tomography scan revealed that 39/464 (8.4%) screws had perforated, but no neurovascular complications occurred. Both surgical strategies improved the ASIA grade and there was no significant difference between the two groups (P = 0.926). The JOA score improved from 6.21 ± 1.85 to 10.90 ± 3.56 in the PSF group and from 6.45 ± 2.17 to 11.48 ± 3.62 in the ASF group, but at the final follow-up, there was no significant difference between the two groups (P = 0.134). The incidence of post-operative complications in the ASF group (24/142, 16.9%) (P = 0.043) was higher than that in the PSF group (6/116, 5.17%). Conclusions: Cervical laminoplasty combined with short-segment transpedicular screw fixation is a reliable option to treat extensional cervical SCIs in patients with CSCS. This surgical strategy is beneficial for achieving sufficient cervical spinal cord decompression, preserving cervical spine stability, and avoiding extra anterior cervical decompression and fusion, thereby reducing surgery time, intraoperative blood loss volume, post-operative complication rate, and length of hospital stay. Relevance for Patients: Cervical laminoplasty combined with posterior segmental fusion (PSF) reduces operative time, bleeding, and complications and achieves adequate spinal cord decompression in the treatment of extension cervical SCI in patients with CSCS.

Total hip replacement after prior of the core decompression of the femoral head: efficacy and complications

Relevance. A history of core decompression using porous tantalum rods has a negative impact on the course of total hip arthroplasty surgery, the postoperative period and the frequency and nature of postoperative complications. Opinions are contradictory with regard to the effect of other techniques of necrosis decompression on total hip arthroplasty.Purpose of the study: evaluation of the effect of core decompression of the femoral head on the intraand postoperative parameters of total hip arthroplasty surgery.Object and methods. The study included 44 patients with osteonecrosis of the femoral head who underwent total hip arthroplasty. The first group consisted of 30 patients with osteonecrosis of the femoral head (ARCO grade II-IV) who had no previous hip surgery – primary total hip arthroplasty. The second group included 14 patients with osteonecrosis who had undergone the core decompression on the same joint (secondary total hip arthroplasty) 6–24 months earlier in stage II of the disease. The duration of surgery, blood loss volume, complications in the postoperative period, pain syndrome dynamics and hip joint function were assessed.Results. Comparative analysis showed the absence of significant technical intraoperative complications in total hip arthroplasty: duration of operations in group I – 85 ± 25 minutes, in group II – 80 ± 20 minutes, that is, almost identical; volume of intraoperative blood loss: 300 ± 100 ml in both groups. Survival rate of the hip replacement was 100 % in both groups. Superficial inflammation of the operating wound was diagnosed in 3.3 % of group I patients and in 7.1 % of group II patients (%). Dislocation of the hip replacement was observed in one patient in Group I (primary total hip arthroplasty). Twelve months after THA, osteolysis around the hip replacement element was detected by X-ray in 6.7 % of group I patients.Conclusion. Total hip arthroplasty in patients with a history of the core decompression of the femoral head is not accompanied by intraoperative technical difficulties and is a relatively safe surgical intervention. Prior core decompression is not an additional risk factor for intraand postoperative complications of total hip arthroplasty.

Effects of Total Hip Replacement and Femoral Head Replacement in the Treatment of Femoral Neck Fractures in Elderly Patients and Their Impacts on Hip Joint Function

Objective: To explore the therapeutic value of total hip replacement and femoral head replacement in elderly patients with femoral neck fractures. Methods: 30 elderly patients with femoral neck fractures were sampled from January 2019 to August 2023 and randomly divided into two groups. Total hip replacement was adopted in the research group, and femoral head replacement was performed in the control group. The surgical indicators, quality of life, hip replacement, Harris hip score, and surgical complications were compared between the groups. Results: The operation time of the research group was longer than that of the control group, and the intraoperative blood loss and postoperative drainage volume were higher than those of the control group, P &lt; 0.05; the SF-36 (36-Item Short Form Health Survey) score of the research group was higher than that of the control group, P &lt; 0.05; the Harris scores of various hip joints of the research group were higher than those in the control group, P &lt; 0.05; the femoral neck fracture complication rate in the research group was lower than that in the control group, P &lt; 0.05. Conclusion: Both total hip replacement and femoral head replacement can improve hip joint function in treating femoral neck fractures in elderly people. However, total hip replacement has better long-term efficacy and can enhance patients’ quality of life and reduce postoperative complications.

Immediate Effects of the Self-Retaining Barbed Suture Material Application &#x0D; for Gastrojejunostomy During Mini Gastric Bypass Laparoscopic Surgery

Background. The safety of self-retaining barbed suture material application when closing wounds of hollow organs and forming anastomoses remains controversial. Data on the use of self-retaining barbed suture material at the stage of a single anastomosis formation during mini gastric bypass laparoscopic surgery (mini gastric bypass - MGB) in the treatment of morbid obesity is scarce and includes both examples of suturing a technological hole after the implementation of a hardware technique, and totally hand-sewn intracorporeal knotless formation of a gastrojejunostomy.The aim of the study was to evaluate the immediate effects of single-row continuous sutures performed with self-retaining barbed unidirectional suture material for intracorporeal hand-sewn gastrojejunostomy during MGB.Methods. The study included 116 patients with grade II-III obesity who underwent MGB. The total duration of operations and the duration of the gastrojejunostomy stage, the volume of intraoperative blood loss, the frequency and severity of intra- and postoperative complications were prospectively studied in accordance with the unified classifications of Satava-Kazaryan and Accordion, respectively. The first group consisted of 56 patients; a conventional synthetic (polydioxanone) monofilament suture material was used for hand-sewn gastrojejunostomy in patients of this group. The second group consisted of 60 patients; gastrojejunostomy was performed with single-needle unidirectional self-retaining barbed absorbable polyester monofilaments in patients of this group. The study groups did not differ significantly in demographic characteristics, body mass index (BMI), the nature of comorbid pathology and the frequency of previous operations.Results. The use of unidirectional self-retaining barbed suture material for a hand-sewn intracorporeal single-row gastrojejunostomy in MGB was accompanied by a significant reduction in the total duration of interventions due to a reduced gastrojejunostomy stage if compared with the use of conventional synthetic monofilaments. The median volume of blood loss during operations did not exceed 50 ml and had no significant differences between groups. Intraoperatively, in patients of the study groups there were registered only complications of the first degree of severity, according to the Satava-Kazaryan classification, with a frequency of 6.7-8.9% (p = 0.737). In the postoperative period, the development of minor complications (first severity of the Accordion system) occurred in 19.6% and 16.7% of patients of the first and second groups, respectively (p = 0.810). The duration of hospital stay was 3.0 (2.5; 3.0) and 2.7 (2.7; 3.0) days in the first and second groups, respectively (р=0,790).Conclusion. The achieved reduced duration of MGB due to the reduced stage of gastrojejunostomy with self-retaining barbed unidirectional suture material, and comparable immediate effects of surgical treatment in patients of the first and second groups demonstrate significant outcomes. Further study is necessary to investigate long-term effects of the knotless suture application for a single anastomosis formation during MGB surgery.

Robot-assisted resection of benign splenic tumors in children

PurposeRobotic surgery is becoming increasingly widely used in the field of pediatric surgery. The present study aimed to evaluate the safety and feasibility of robot-assisted resection of benign pediatric splenic tumors and to discuss the technical points.MethodsA total of 32 patients who were diagnosed with benign splenic tumors and underwent minimally invasive surgery from January 2017 to September 2023 were included in the study. The clinical data including demographic criteria, operative details, and postoperative outcomes were analyzed retrospectively.ResultsThirteen patients underwent robot-assisted surgery, and 19 patients underwent laparoscopic surgery. The median operation time was 150 min, with an interquartile range (IQR) of 120 to 200 min for the robot-assisted group and 140 min with an IQR of 105 to 180 min in the laparoscopic group (P = 0.318). Despite four cases in the laparoscopic group (21%) being converted to laparotomy because of intraoperative bleeding, compared with none in the robot-assisted group, there was no significant difference between two groups (P = 0.128). The intraoperative volume of blood loss was significantly less (P = 0.041), and the hospitalization expense was significantly higher (P = 0.000) in the robot-assisted group than for the laparoscopic group. There was no significant difference in patients’ age, tumor size, postoperative feeding time, and the postoperative hospitalization time between two groups (P > 0.05).ConclusionRobot-assisted benign splenic tumor resection was safe and feasible, and it reduced surgical trauma for the pediatric patient.

Feasibility and safety of choledochotomy primary closure in laparoscopic common bile duct exploration without biliary drainage: a retrospective study

Common bile duct (CBD) exploration and T-tube drainage are the main surgical methods for the removal of bile duct stones (BDSs), which can now be completed by laparoscopy. However, the feasibility and safety of primary closure of the CBD (PCCBD) in laparoscopic CBD exploration (LCBDE) without biliary drainage are still uncertain. From January 1, 2021, to June 30, 2022, patients who were diagnosed with BDSs and underwent LCBDE and primary closure of the CBD without biliary drainage in our hospital were included. The clinical and prognostic data of the patients were retrospectively analyzed to determine the feasibility and safety of PCCBD in LCBDE without biliary drainage. Forty-nine patients successfully underwent PCCBD in LCBDE without biliary drainage. The operation time was 158.8 ± 50.3 (90–315,150) minutes, the bile duct suture time was 17.6 ± 4.46 (10–26, 18) minutes, the intraoperative blood loss volume was 70.4 ± 52.6 (5–200, 80) ml, the hospitalization cost was 28,141.2 ± 7011.3 (15,005.45–52,959.34, 26,815.14) CNY Yuan, the hospitalization time was 13.22 ± 5.16 (8–32, 12) days, and the postoperative hospitalization time was 7.31 ± 1.94 (3–15, 7) days. There were 3 cases of postoperative bile leakage (3/49, 6.12%), all of them healed by nonsurgical treatment. During the follow-up of 17.2 ± 11.01 (10–26, 17) months, no residual BDSs, biliary stricture or other complications classified as Clavien-Dindo grade I or higher occurred. For some selected patients who meet certain criteria, PCCBD in LCBDE without biliary drainage is feasible and safe and is more conducive to the rapid postoperative recovery of patients.

New method for determining volume of intraoperative blood loss during burn treatment surgery

BACKGROUND: Nowadays, there are numerous ways to assess the volume and minimize intraoperative blood loss; however, their effectiveness is subjective. To compare the effectiveness of blood-saving techniques, it is necessary to create new more reliable methods for determining intraoperative blood loss.&#x0D; AIM: To develop a new technique for determining intraoperative blood loss in the surgical treatment of burn victims.&#x0D; MATERIALS AND METHODS: In the course of the study, we have developed and proposed our own, original method for determining the volume of intraoperative blood loss, taking into account the indicators of hemoglobin and hematocrit as well as a differentiated calculation of the volume of circulating blood. This technique has been tested on 82 victims with deep burns of the II–III degree (International Classification of Diseases 10th Revision), who were admitted to the department of thermal lesions in the period from April 2021 to December 2021. The data obtained have been processed in the Microsoft Excel 2007 program as well as by generally accepted methods of nonparametric statistics.&#x0D; RESULTS: The methods currently available have a large variability of results when performing the same intervention. The developed technique shows a stable relationship between the volume of blood loss and the area of the excised scab.&#x0D; CONCLUSIONS: The data obtained allow to conclude that the new method for determining blood loss in burn victims appears to be a simple and effective method. The new technique will allow to find the most effective methods of minimizing blood loss during surgical necrectomies, which will reduce the need for additional hemotransfusions and promote earlier rehabilitation of burn treatment.

Dual-portal robotic-assisted thoracic surgery (DRATS) as a reduced port RATS: early experiences in three institutions in Japan.

Robotic-assisted thoracic surgery (RATS) has gained increasing interest in recent years, with most procedures performed using the conventional multiportal approach. Uniportal RATS (URATS) approaches have recently been reported in the pursuit of minimally invasive procedures. However, URATS requires specific skills. Herein, we introduce dual-portal RATS (DRATS) performed with two incisions. Data of DRATS procedures performed from December 2022 to May 2023 were retrospectively reviewed. Twenty patients with lung cancer underwent anatomical lung resections via DRATS performed by our group at three institutes. Among 20 cases of planned DRATS for anatomical pulmonary resections, there were no conversions to thoracotomy and no need for extra ports. The mean surgery time was 121±60 minutes and mean console time was 91±47 minutes. The mean intraoperative blood loss volume was 9.6±12.1 g. The mean duration of chest tube drainage and hospital stay were 2±1 and 5±2 days, respectively. The mean numerical rating scale for pain was 2±1 on the first postoperative day, 1±1 on the third day, and 1±1 at discharge. There were no postoperative complications or mortalities. Our primary experience shows that DRATS is safe and feasible for anatomical lung resection. We consider DRATS to be a very good preliminary step in the future transition to URATS.

Assessing the Clinical Efficacy and Effectiveness of Sentinel Lymph Node Biopsy Combined with Breast-Conserving Surgery for Early-Stage Breast Cancer

Objective: To analyze the impact of sentinel lymph node biopsy (SLNB) combined with breast-conserving surgery in the clinical treatment of early-stage breast cancer. Methods: 80 patients with early-stage breast cancer admitted to the Second Department of Breast Surgery at Dezhou Second People’s Hospital from September 2020 to September 2022 were selected and randomly divided into a control group and an observation group using the random number table method, with 40 cases in each group. The control group underwent a modified radical mastectomy, while the observation group underwent SLNB combined with breast-conserving surgery. The surgical efficacy and prognosis between the two groups were compared. Results: The observation group exhibited shorter operation, hospitalization, and extubation times, as well as less intraoperative blood loss and drainage volume, all of which were significantly better than those in the control group (P &lt; 0.05). Additionally, the observation group demonstrated a higher rate of excellent breast cosmetology and quality of life, with lower complication incidence, significantly outperforming the control group (P &lt; 0.05). There was no statistical difference in the metastasis rate and recurrence rate between the two groups (P &gt; 0.05). Conclusion: The combination of SLNB and breast-conserving surgery proves highly effective for patients with early-stage breast cancer, presenting fewer complications and enhancing both breast cosmetic outcomes and quality of life.

Laparoscopic-Assisted Scrotal Approach for the Treatment of Inguinal Cryptorchidism with Patent Processus Vaginalis: Clinical Efficacy Analysis.

Objective: This study aimed to compare the clinical outcomes of two surgical approaches, laparoscopic-assisted scrotal incision and conventional inguinal-scrotal incision, for treating cryptorchidism with unobliterated processus vaginalis. Methods: Clinical data from 60 pediatric patients with inguinal cryptorchidism who were admitted to our institution between January 2018 and January 2022 were retrospectively analyzed. Depending on the surgical technique used, the patients were split into two groups: the laparoscopic group (n = 30) underwent a laparoscopic-assisted scrotal incision, whereas the conventional group (n = 30) underwent a conventional inguinal-scrotal incision for testicular descent and fixation. The length of the procedure, intraoperative blood loss, and the typical hospital stay following the procedure were compared between the two groups. Also assessed was the frequency of postoperative complications including wound infection and hematoma development. Results: The laparoscopic group demonstrated a notably shortened average surgical duration compared with the traditional group, and this discrepancy held statistical significance (P = .017). Moreover, the laparoscopic approach resulted in a reduced volume of intraoperative blood loss, with a statistically significant distinction (P = .002), along with a decreased average length of hospital stay after surgery, also statistically significant (P = .009). Testicular retraction, atrophy, inguinal hernias, or hydrocele were not present in any group. Although the difference between the laparoscopic and open groups was not statistically significant (P > .05), the laparoscopic group saw a reduced frequency of scrotal hematoma. The frequency of wound infection was also decreased in the laparoscopic group compared with the open group, although there was no statistically significant difference (P > .05). Conclusion: The laparoscopic-assisted scrotal incision approach for testicular descent and fixation offers precise localization of cryptorchidism, reduced surgical trauma, shorter postoperative recovery time, and results in smaller scars with minimal tissue damage. The procedure showcases enhanced overall clinical effectiveness, fewer postoperative complications, heightened safety, and superior cosmetic outcomes.

Anti-infective therapy durations predict psychological stress and laparoscopic surgery quality in pelvic abscess patients

BACKGROUND The degree of psychological stress and the difficulty and efficacy of laparoscopic surgery differ in patients with pelvic abscesses after different durations of anti-infection treatment. AIM To compare and analyse the effects of different durations of anti-infective therapy on patients’ preoperative psychological stress level and the clinical efficacy of laparoscopic surgery in patients with pelvic abscesses to offer a reference for the selection of therapy plans. METHODS A total of 100 patients with pelvic abscesses who were admitted to the Department of Gynecology of Suzhou Ninth Hospital affiliated to Soochow University (Suzhou Ninth People's Hospital) from January 2018 to December 2022 were retrospectively enrolled. According to the different durations of anti-infective therapy, they were divided into Group S (50 patients, received anti-infective therapy for 24-48 h) and Group L (50 patients, received anti-infective therapy for 48-96 h). Baseline data, state-trait anxiety score at admission and before surgery, self-rating anxiety scale (SAS) + self-rating depression scale (SDS) score, surgery time, adhesion grading score, intraoperative blood loss, presence or absence of intraoperative intestinal injury, ureteral injury or bladder injury, postoperative body temperature, length of hospital stay, and presence or absence of recurrence within 3 mo after surgery, chronic pelvic pain, incision infection, dysmenorrhea, menstrual disorder or intestinal obstruction were compared between the S group and the L group. RESULTS There was no significant difference in the background data between the S group and the L group (P &lt; 0.05). There was no significant difference in the state-trait anxiety score or SAS + SDS score between the S group and the L group on admission (P &lt; 0.05). The state-trait anxiety score and SAS + SDS score of the S group were lower than those of Group L after receiving different durations of anti-infective therapy (P &lt; 0.05). There was no significant difference in the incidence of intestinal, ureteral or bladder injury between the S group and the L group (P &lt; 0.05). The surgery time of Group S was shorter than that of Group L, and the adhesion score and intraoperative blood loss volume were lower than those of Group L (P &lt; 0.05). There was no significant difference in the incidence of incision infection, dysmenorrhea, menstrual disorder or intestinal obstruction between the S group and the L group (P &lt; 0.05). The postoperative body temperature of Group S was lower than that of Group L (P &lt; 0.05), and the hospital stay was shorter than that of Group L (P &lt; 0.05). The incidences of recurrence and chronic pelvic pain within 3 mo after surgery were lower than that of Group L (P &lt; 0.05). CONCLUSION Twenty-four to forty-eight hours of anti-infective therapy is better than 48-96 h of anti-infective therapy for patients with pelvic abscesses because the degree of psychological stress is lower, which is more conducive to achieving better outcomes after laparoscopic surgery.

IS A COCCYGECTOMY AN EFFICACIOUS SURGICAL TREATMENT FOR DEBILITATING COCCYGEAL PAIN?

To determine the demographic, pre-operative, operative, post-operative, and outcome in seven patients who presented to our unit over a 5-year period and underwent a coccydectomy for coccydynia unresponsive to conservative measures.We performed a retrospective chart review of seven patients who presented to the Department of Orthopaedics at Helen Joseph hospital, University of the Witwatersrand, Johannesburg, South Africa, with coccidia unresponsive to a trial of adequate conservative measures, and underwent operative intervention. The study period was from 01 January 2014 to 31 December 2018.The mean age of subjects in our study was 53 years. The average length of conservative treatment prior to presentation to our unit was 8 months. All patients were taken to surgery and the mean length of surgery was 49 min and the mean volume of intra-operative blood loss was 63.4 ml. In all 7 (100%) of subjects a total coccygectomy was performed. At our 1-year end point all 7 (100%) subjects reported a favourable outcome and were satisfied – extremely satisfied with the procedure.In our study a total coccygectomy resulted in a significant reduction in coccygeal pain and subjects a 1-year follow-up end point. We recommend that in patients who fail an adequate recognized trial of conservative measures for coccydynia, a total coccygectomy should be performed.
