Urinary incontinence in elite female powerlifters aged 20-30: correlating musculoskeletal exam data with incontinence severity index and survey data.

Urinary incontinence (UI) in the powerlifting community has been a hot topic due to its noticeability during competition and the burden it places on female athletes who experience it. UI is even experienced in those we least expect: young, high-performing, females with no history of pregnancy. Current studies have utilized primarily survey methodology, thus there is a lack of clinical information on this topic. Furthermore, the top athletes are underrepresentedbecause previous surveys were open to anyone reporting themselves as a powerlifter, regardless of competition level. The objectives of this study were to determine whether UI in elite female powerlifters is correlated with any musculoskeletal diagnoses and to further evaluate potentially contributing factors for UI within this group. Subjects underwent an osteopathic structural examination and then completed two surveys: the Incontinence Severity Index (ISI/Sandvik Test for Urinary Incontinence) and the Study Questionnaire. In total, there were 31 female participants, all of whom were in the top 2 % of powerlifters in the world between the ages of 20 and 30 years old (as of May 21, 2023) and reside in the United States. The survey results displayed a moderately positive relationship between age (rho=0.449, where rho refers to Spearman's rho), history of pelvic floor examination (rho=0.413), and self-care practice with ISI (rho=0.340). Other survey information such as weight class, height, best total in competition, number of years training, average duration of training day, confidence in ability to contract pelvic floor muscles, history of abdominal or pelvic surgery, history of urinary tract infection (UTI), and sexual activity status all had rho values less than 0.300. With atlantoaxial (AA) rotation to the right, there was an increase in ISI score (p=0.009). Similarly, with AA rotation to the left, there was a decrease in ISI score (p=0.030). All patients with severe ISI had nonphysiologic sacral dysfunctions (p=0.051). Severe ISI-scored participants were more likely to yield a dysfunctional clavicle upon screening (p=0.027). There was a strong correlation between increasing severity of UI and findings of a restricted right clavicle and/or AA rotation to the right (p=0.010). In addition, there were only two individuals with both a restricted right clavicle and AA rotation to the right, and these two individuals both scored severe on the ISI (p=0.012). A pelvic diaphragm dysfunction was present in 74.2 % of the participants. Extension diagnoses of the lumbar spine were found in those with mild UI over those with severe UI (p=0.012). Most other diagnoses were largely unremarkable due to a wide distribution across all ISI scores. Our study revealed a relationship between UI and somatic dysfunctions in this population. These findings may help providers, especially in the fields of primary care, sports medicine, and urogynecology, to expand treatment options for UI in this group in the future. Survey results yielded a positive relationship of moderate strength between age, history of pelvic floor exination, and engaging in leakage prevention practices with ISI. No survey category was found to have a relationship of high strength with ISI. These findings contribute to our knowledge on factors that do (or do not) contribute to incontinence severity.

Incidence of Incisional Hernias after Single-Port Versus Multi-Port Robotic Radical Prostatectomy.

Purpose: To determine if single-port robotic-assisted radical prostatectomy (SP-RARP) has higher rates of incisional hernias when compared with multi-port robotic-assisted radical prostatectomies (MP-RARP). Materials and Methods: A retrospective, single-institution review of all consecutive robotic prostatectomy cases between January 2017 and December 2022. Analyzed multi-port and single-port robotic prostatectomies performed by two high-volume surgeons. Measured primary outcome for the development of incisional hernias, as defined by computed tomography imaging and clinical documentation. Multivariable logistic regression was used to determine the effect of the single-port approach on incisional hernia outcomes. Results: A total of 493 patients were included in the study (320 SP-RARPs and 173 MP-RARPs). The overall incisional hernia rate was 8.5% (SP-RARP 8.1% vs MP-RARP 9.2%, p = 0.669). A median follow-up time was 16.6 months and a median time from procedure to hernia diagnosis was 7.4 months. SP-RARP had shorter OR time than the MP-RARP (236 minutes vs 276 minutes, p < 0.001). Patients who developed hernias had higher body mass index (BMIs) than those who did not (30.7 vs 29, p = 0.009). Multivariable logistic regression analysis revealed that patients with higher BMI (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.01-1.14) and a history of prior operation (OR 2.23, 95% CI 1.71-4.29) were more likely to develop incisional hernias. Cox regression analysis accounting for the difference in follow-up period demonstrated that SP-RARP 3.4× more likely to develop incisional hernias than MP-RARP (hazard ratio 3.38, 95% CI 1.50-7.58). Conclusions: Patients with higher BMIs and prior history of abdominal surgeries are at increased risk of developing postoperative incisional hernias. SP-RARP procedures confer a higher risk of postoperative incisional hernias.

EDI&amp;S SO06 Do All Patients with Biliary Problems Need Surgery? Applying C-Gall Study Results to Long Waiters for Laparoscopic Cholecystectomy

Abstract Background The recent C-GALL study, a multi-centre randomised trial, found no significant difference in quality of life at two years between operative and non-operative management of uncomplicated gallstone disease. This suggests some patients may not benefit from elective laparoscopic cholecystectomy (LC), potentially leading to over-listing for surgery. By identifying patients who may no longer need surgery, we could reduce waiting lists and improve resource allocation. This study aims to reassess patients with an enforced period of observation on an elective waiting list for LC, to determine if they wish to make a different decision about proceeding with surgery. Method Patients listed for an elective LC who had been waiting longer than 11 months from referral were reviewed. Patients were contacted through telephone clinics by a surgeon. Data was collected on type of gallstone disease, history of abdominal surgery, biliary pain since last seen by a clinician, pain radiation to the back, pain reduction with simple analgesia, nausea, and heartburn. Identified patients were contacted and, if exhibiting minimal or no symptoms, were offered the option to be removed from the waiting list with 12 months of patient-initiated follow-up and high priority relisting if their clinical condition worsened. Results We contacted 59 patients awaiting elective LC Most were female (49, 83%), had biliary colic (43, 73%), and were under 60 years old (38, 64%). Seventeen patients (29%) were happy to opt out due to lack of symptoms. Of these, 13 (76%) were female, 11 (65%) had biliary colic, and 7 (41%) were under 60. Chi-squared analysis identified age as the only predictive factor, with those under 60 being less likely to opt out (p=0.038). We will continue to monitor representation and the need for reoperation to ensure safety and the findings remain consistent overtime. Conclusion The study demonstrates that a significant proportion of patients awaiting elective LC can be safely managed without planned cholecystectomy, potentially reducing waiting lists, cost and utilisation of healthcare resources. We would advise considering review of long waiters to re-evaluate their clinical need for cholecystectomy in order to improve sustainability within surgery. These findings support a more personalised approach to managing biliary pain, prioritising patients for surgery based on symptom severity.

Risk factors for wound complications after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) compared to repeated liver resection - a propensity score matching analysis

AimSufficient liver function is crucial in extracellular matrix growth, hemostasis, and wound healing. Repeated abdominal surgery is a known risk factor for the development of wound complications. This study aimed to evaluate this high-risk constellation in patients undergoing associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) and repeated liver resections (RLR) in comparison to single liver resection (SLR).MethodForty patients who underwent ALPPS between 2011 and 2020 were evenly matched with patients undergoing RLR or SLR (n = 40 per group) using propensity scores. Postoperative outcomes were compared and factors associated with wound complications were analyzed.ResultsPostoperative wound complications were significantly more frequent in ALPPS group (p = 0.001). The reoperation rate was not significantly different between the three groups (p = 0.143). However, surgical reintervention due to wound complications occurred more frequently in the ALPPS group in relation to RLR and SLR (17.5% vs. 7.5% and 5% respectively). Length of stay was significantly longer in the ALPPS group (p = 0.033). ALPPS was an independent risk factor for postoperative wound complication (OR = 8.55, 95% CI:1.07–68.44, p = 0.043). Risk factor analysis identified age ≥ 60 years (OR = 27.64, 95% CI:3.09-246.75, p = 0.003), BMI ≥ 30 kg/m2 (OR = 30.21, 95% CI:3.35-271.83, p = 0.002), and low postoperative albumin levels (OR = 168.41, 95% CI:7.76-3651.18, p = 0.001) as independent predictors of postoperative wound complications after major liver resection.ConclusionPatients undergoing ALPPS and RLR are faced with a high risk of developing wound complications. Older age, obesity, a history of previous abdominal surgery, and a decreased postoperative albumin level were independent risk factors for wound complications.

Myosteatosis Evaluated Based on Intramuscular Adipose Tissue Content Is a Risk Factor for Postoperative Complications in Crohn's Disease.

Crohn's disease causes acute and chronic inflammation that often make the preoperative evaluation of surgical risks difficult. Myosteatosis is used for the evaluation of muscle quality to assess sarcopenia. However, data on the relationship between myosteatosis and surgical outcomes in patients with Crohn's disease are lacking. Among patients with Crohn's disease who underwent surgery between 2007 and 2022, we investigated the impact of myosteatosis on postoperative complications using intramuscular adipose tissue content (IMAC). Our study included data from 97 patients who underwent analysis for cutoff values and factors associated with IMAC and 72 who underwent analysis for risk factors of postoperative complications. Body mass index (BMI; P < .001) and visceral adipose tissue/height index (P < .001) were significantly correlated with IMAC. High BMI (P < .001) and a history of abdominal surgery for Crohn's disease (P = .012) were identified as factors affected with high IMAC. Multivariate analysis revealed high IMAC and external fistulas as independent risk factors for postoperative complications (odds ratio [OR], 5.010; 95% CI, 1.300-19.30; P = .019 and OR, 7.850; 95% CI, 1.640-37.50; P = .010, respectively), especially infectious complications. This study established IMAC as a valuable marker for sarcopenic obesity and predicting postoperative complications in patients with Crohn's disease. Furthermore, evaluating myosteatosis using IMAC will facilitate the decision of the optimal timing of surgery, prediction of complications, and treatment of sarcopenia in patients with Crohn's disease.

Laparoscopic versus open surgery for liver resection: a multicenter cohort study

The relative risk and benefits of Laparoscopic liver resection (LLR) are still controversial. This study aimed to evaluate perioperative and survival outcomes for three primary malignant liver tumors related outcomes following LLR. Data from three Homogeneous-High-Volume-Expert-Centers were collected. Multivariable logistic regression analysis was performed for the association between LLR, and major complications defined as Clavien-Dindo Classification grade ≥ II. Multivariable Cox proportional hazards regression was used to explore the impact of LLR on primary malignant liver tumor survival. Overall, 5886 patients underwent liver resection, of which 1991 underwent LLR. After adjusting for covariables, LLR had significantly lower rate of CDC grade ≥ II (OR = 0.56, 95% CI: 0.48–0.67, P < 0.001). Interaction analysis showed that LLR had significant association with sex, drinking status, history of abdominal surgery, and platelet count (all P < 0.05). The overall survival for each primary malignant liver tumor shown potential risk but without significantly different between LLR and OLR (all P > 0.05). LLR was associated with lower rate of major complications, especially in women, non-drinkers, those without a history of abdominal surgery, and those with normal platelet. For primary malignant liver tumors, the survival outcomes did not differ significantly between LLR and OLR.

Comparative analysis of the oncologic outcomes and risk factors for open conversion in laparoscopic surgery for non-metastatic colorectal cancer: A retrospective multicenter study

PurposeLaparoscopic colon surgery is now commonly used for colorectal cancer (CRC) resection. The objective of this study was to compare the oncologic outcomes between open conversion and laparoscopic surgery, and to identify risk factors for open conversion. MethodsWe retrospectively reviewed the medical records of patients who underwent curative resection for stage 0–III CRC at five Hallym University-affiliated hospitals between January 2011 and June 2021. The patients were divided into the conversion and laparoscopic groups according to whether laparoscopic surgery was completed. ResultsOut of 2231 patients, laparoscopic surgery was completed in 2131 patients and 100 (4.5 %) converted to open surgery. The operation time (P = 0.028) and postoperative hospital stay (P = 0.036) were longer in the conversion group than in the laparoscopic group. Overall (P = 0.022) and severe (Clavien–Dindo classification grade ≥3) (P = 0.048) complications were more frequent in the conversion group than in the laparoscopic group. The 5-year recurrence-free survival (RFS) rate was worse in the conversion group than in the laparoscopic group (P = 0.002). In the multivariable analysis, open conversion was not a prognostic factor for RFS (P = 0.082). Abdominal surgery history (P = 0.021), obstruction (P < 0.001), and T4 stage (P < 0.001) were independently associated with open conversion. ConclusionThe conversion group had worse perioperative and oncologic outcomes. History of abdominal surgery, obstruction, and T4 stage were associated with open conversion. However, conversion itself was not associated with RFS.

Considering factors for breast reconstruction using stacked profunda artery perforator flaps in an Asian patient: a case report

In cases where there is insufficient abdominal tissue or a history of previous abdominal surgery, thigh tissue may be considered as an alternative for reconstruction. This report discusses a case involving a 49-year-old Asian woman with thin abdominal fat and thick thigh fat, who underwent a right nipple-sparing mastectomy followed by bilateral profunda artery perforator flap breast reconstruction. The discussion will address specific considerations relevant to Asian patients preoperatively.

Association between different patterns of obesity and the short-term outcomes of gastric cancer surgery.

Previous studies have shown that general and central obesity are each linked to adverse outcomes in gastrointestinal cancers. However, their combined effect on gastrointestinal cancers surgery outcomes were less understood. This study aims to integrate both general and central obesity to examine the outcomes of gastric cancer surgery in different obesity patterns. We retrospectively analyzed 248 patients who underwent gastric cancer surgery between 2021 and 2023 in a single institute. The Inbody720 body composition analyzer measured body composition. We evaluated the relationship between obesity patterns - combining BMI with central obesity measures (waist circumference, waist-to-hip ratio, visceral fat area) - and postoperative complications and 30-day readmission. Central-only obesity were more likely to induce fistula (P = 0.025), while non-obesity was more likely to develop postoperative abdominal effusion (P = 0.049) and bleeding (P = 0.042). Central-only obesity was significantly associated with severe postoperative complications after adjustment for hypertension, diabetes, abdominal surgery history, preoperative albumin levels, age, sex, and surgical types. This remains significant even after adjusting for muscle mass. However, we did not find the same results for significant complications. Regarding 30-day readmission, there are no differences between different patterns of obesity. Central-only obesity is an independent risk factor for severe postoperative complications in gastric cancer, while a high BMI appears to be associated with a lower risk compared to non-obese patients, but not significant postoperative complications. The likelihood of readmission within 30 days post-surgery may not be related to the patient's pattern of obesity.

An open comparative randomized prospective study: Direct trocar insertion vs Veress needle technique in laparoscopic surgeries.

Laparoscopy is a minimally invasive technique utilized for both diagnostic and surgical approaches. Minimally invasive procedures compared to laparotomy offer the advantages of reduced hospital stay, lower morbidity, decreased pain, and faster recovery. Common methods for laparoscopic entry include Veress needle insertion (VNI), direct optical trocar entry, direct trocar insertion (DTI), and the Hasson technique. This study aims to compare the efficacy and safety of VNI and DTI in laparoscopic gynecological surgeries. An open comparative randomized prospective study was conducted involving 200 women aged 18 to 70 years, scheduled for laparoscopic surgery at 2 tertiary centers. Participants were randomized into 2 groups: 1 using VNI and other using DTI. The groups were homogeneous regarding age, parity, and body mass index. The mean age of the VNI group is 45.22 ± 11.65 and the DTI group is 44.89 ± 10.5 (P = .833). There were no statistical significance in terms of the presence of chronic diseases and history of previous abdominal surgery between the groups (P = .802 and P = .510, respectively). Entry time to the abdomen, the decrease in hemoglobin values, and hospitalization length were found to be statistically significant between the entry methods (P < .001, P = .002, and P < .001, respectively). Entry time, the decrease in hemoglobin value, and hospitalization length were higher in the VNI group. In conclusion, although there is no definitive consensus on the optimal laparoscopic entry technique, direct trocar entry is an effective alternative to the Veress needle insertion technique. Direct trocar entry is associated with shorter entry times, fewer perioperative complications, less reduction in hemoglobin levels, and shorter hospitalization duration compared to VNI.

Modified Peritoneal Fenestration as a Preventive Method for Lymphocele after Kidney Transplantation: A Preliminary Report.

Background: We aimed to assess the safety of a modified peritoneal fenestration technique with clipping of the window edges during kidney transplantation (KTx) and to determine its impact on reducing lymphocele following KTx. We compared the outcomes of this modified method with those of peritoneal fenestration without clipping. Methods: Among 430 consecutive KTxs performed between 2015 and 2019, preventive peritoneal fenestration and clipping of the margins were performed in 25 patients. These patients were compared with 75 matched patients in whom the margins were not clipped. Postoperative lymphocele formation and other patient data were compared between these two groups. Results: The rate of clinically relevant lymphocele decreased by 2.7% after peritoneal fenestration with clipping, although this decrease was not statistically significant (p = 0.829). There was no significant increase in the rate of other complications in the modified fenestration group (p = 0.067). The incidence of clinically significant lymphocele formation was notably higher in patients with a body mass index greater than 25 kg/m2 (p = 0.028). Univariate analysis indicated that older recipients, individuals with a history of previous abdominal surgery, those receiving the kidney from deceased and older donors were at increased risk of developing a clinically relevant lymphocele. Conclusions: Our preliminary results suggest that peritoneal fenestration with clipping may be as effective as the conventional fenestration technique in preventing lymphocele formation. Further clinical trials with larger sample sizes are required to determine the exact role of preventive peritoneal fenestration with clipping in preventing clinically relevant lymphocele after KTx.

Intra-Abdominal Candidiasis in Cancer Patients: A 10-Year Experience in a Middle-Income Country.

Invasive candidiasis (IC) represents a significant threat to both mortality and morbidity, especially among vulnerable populations. Intra-abdominal candidiasis (IAC) frequently occurs in critically ill and cancer patients, with these specific groups carrying a heightened risk for such invasive fungal infections. Despite this, there is a noticeable lack of attention to IAC in cancer patients within the literature, highlighting a critical gap that requires urgent consideration. This study aimed to explore the clinical and epidemiological characteristics of IAC and identify prognostic factors in a cancer centre in a middle-income country over 10 years. A retrospective cohort observational study of adults diagnosed with IAC was conducted at the Instituto do Cancer do Estado de São Paulo (ICESP), a tertiary hospital specialising in oncological diseases with 499 beds, including 85 intensive care unit (ICU) beds, from December 2009 through May 2021. A total of 128 episodes were included: 67.2% admitted to the ICU; 54.7% males; and median age 62 years. The predominant diagnosis was peritonitis (75.8%). Blood culture samples were collected from 128 patients upon admission, revealing candidemia in 17.2% (22). The most frequently isolated were C. albicans (n = 65, 50.8%) and C. glabrata (n = 42, 32.8%). Antifungal treatment was administered to 91 (71%) patients, with fluconazole (64.8%) and echinocandins (23.4%) being the most common choices. A significant proportion of these patients had a history of abdominal surgery or antibiotic use. Independent factors associated with 30-day mortality included the median Sequential Organ Failure Assessment (SOFA) score of 6 (OR = 1.30, 95% CI 1.094-1.562, p = 0.003), days of treatment (median 10.5) (OR = 0.93, 95% CI 0.870-0.993, p = 0.031) and abdominal source control (78.1%) (OR = 0.148, 95% CI 0.030-0.719, p = 0.018). The 30-day mortality rate was 41.1%. Our study underscores the critical importance of implementing effective source control as a key strategy for reducing mortality in IAC.

Assessment of Pre-Operative Predictive Factors Favoring Conversion from Laparoscopic to Open Cholecystectomy in Acute Cholecystitis

Abstract Background Acute cholecystitis refers to inflammation of the gallbladder. The pathophysiologic mechanism of acute cholecystitis is blockage of the cystic duct. Accurate diagnosis of cholecystitis requires a multifactorial, systematic approach that involves a detailed history, physical exam, serologic tests, and imaging. The (Tokyo guidelines 2018) diagnostic criteria for acute cholecystitis is widely used now days and well accepted. Objective To asses pre-operative predictive factors favoring conversion of laparoscopic cholecystectomy into open cholecystectomy in acute cholecystitis such as: (TLC- history of DM and previous abdominal surgery -gall bladder wall thickness _ pericholecystic fluid collection and loss of gallbladder wall enhancement on CT). Patients and Methods This study included 100 patients admitted to Ain Shams university hospitals diagnosed with acute cholecystitis, underwent laparoscopic cholecystectomy, half of them converted to open cholecystectomy, the two groups are compared to each other to figure out preoperative factors favoring conversion cholecystectomy Results Obesity (BMI≥30 kg/m2) in this study has shown to be associated with risk of conversion in this study. In converted group there is 25 (50%) patients who are obese compared to 14 (28%) patients in laparoscopic group with P-value of 0.04. In our study we haven’t assessed the role of intraoperative findings on conversion rate. We chose not to include this factor in our analysis to make primary concern regarding pre-operative factors. Conclusion Obesity, DM, previous abdominal surgery, loss of gallbladder wall enhancement in CT study and prolonged prothrombin time are risk factors of conversion cholecystectomy in acute cholecystitis. Appropriate management of risk-related preoperative factors may improve patients’ outcomes making in mind the concept of conversion to open cholecystectomy should not be viewed as a complication or a failure but just the opposite. It is showing good judgment to complete the operation in the safest manner possible.

Robotic pancreaticoduodenectomy after open Roux-en-Y biliary-enteric anastomosis: Technical insights (with video)

TechniqueRobotic pancreaticoduodenectomy (RPD) presents a formidable surgical challenge for patients with a prior history of bilioenteric anastomosis. However, there are no reports in the literature of robotic pancreaticoduodenectomy after open bilioenteric anastomosis. This article offers a detailed description of the surgical technique employed in performing RPD on a patient who previously underwent open Roux-en-Y biliary–enteric anastomosis, aiming to treat a duodenal tumor. ResultsThe patient underwent a successful surgery with a total operation time of 320 min and an estimated blood loss of approximately 150 ml. Following the procedure, the patient experienced an uncomplicated recovery and was discharged from the hospital after a 14-day hospitalization period. Postoperative pathology revealed a moderately differentiated adenocarcinoma of the duodenum invading the entire layer of the bowel wall. ConclusionsRPD is a safe and viable option for patients with a history of complex abdominal surgery.

Single-port extra-peritoneal robotic radical prostatectomy in a patient with hostile abdomen.

This video explores the technique and outcomes of robotic radical prostatectomy (RP) using the da Vinci single-port robot in a 42-year-old obese male with localized intermediate-risk prostate cancer and a prior history of extensive abdominal surgeries. The patient was placed in a supine position, with minimal Trendelenburg, and an extraperitoneal approach was taken, the abdominal cavity was not entered, and standardized steps of robotic RP were executed. The surgery lasted 190 min and the blood loss was 100 mL. The patient was discharged on the postoperative day 1, and the prostate-specific antigen was undetectable after 6 months and he had excellent functional outcomes.

Congenital trans-mesentric internal hernia: a rare cause of acute intestinal obstruction in adult

Introduction and Importance: Internal hernia is responsible for 0.6–5.8% of all small intestinal obstructions. Only 8% of internal hernias are of the congenital trans mesenteric variant. Urgent surgical intervention should be considered in individuals who exhibit intestinal obstruction before the development of irreversible bowel ischemia and necrosis. Case Presentation: The authors report a 38-year-old male patient who presented to the emergency department with abdominal pain, distension, and vomiting for the last three days. After an explorative laparotomy, it was confirmed that there was a trans mesenteric hernia defect with strangulated distal ileal loops. End-to-end ileo-ileal anastomosis was done. Clinical Discussion: Early recognition and subsequent surgical treatment permit proper management and prevent complications. There should be a differential diagnosis. In this case, there is no prior history of abdominal surgery, and the patient presents with recurrent abdominal pain and intestinal obstruction. Conclusion: Early diagnosis and emergency laparotomy can save the intestine before gangrene, lowering morbidity and mortality, correcting the mesenteric defect to prevent recurrences, and enhancing clinical outcomes because many studies have shown that some cases are missed before radiological investigation. Laparotomy is still the method of choice for acute cases of incarceration with bowel obstruction, strangulation, and ischemia. The entire mesentery needs to be evaluated, and all mesenteric defects need to be sutured to prevent recurrence.

Bikini line one-anastomosis gastric bypass (BLOGB): initial report

BackgroundThis study introduces a new access method for one-anastomosis gastric bypass (OAGB) by placing ports at the bikini line.ObjectiveTo describe our initial experience and assess the feasibility, safety, and effectiveness of this novel access.SettingUniversity Hospital.MethodsThis prospective case–control study included 72 patients: 42 were allocated to the bikini line one-anastomosis gastric bypass (BLOGB) group, and 30 were assigned to the control group. Exclusion criteria included a history of major abdominal surgery, hiatal hernia, extensive lower abdominal adhesions, or a body mass index (BMI) exceeding 55 kg/m2.ResultsThe mean preoperative BMI of the study sample was 40.01 ± 2.84. Weight loss was satisfactory, with the highest percent excess weight loss (%EWL) observed at 12 months: 90.88 ± 7.90 and 91 ± 7.11 (p = 0.474) in both groups, respectively. Both groups showed no significant differences in operative complications, hospital stay, weight loss, or resolution of obesity-associated diseases. However, the BLOGB patients had a longer mean operative time of 110.71 ± 17.72 min compared to 98 ± 18.27 min in the control group (p = 0.002). Moreover, they experienced less postoperative pain and reported greater satisfaction with the appearance of their scars.ConclusionBLOGB was found to be potentially feasible, safe, and effective, offering improved aesthetic outcomes and reduced postoperative pain. This approach may be suitable for a select group of patients concerned with scar appearance. However, large-scale studies are necessary to ensure that safety is not compromised in pursuit of aesthetic benefits.

Learning curve for a five-step procedure, transthoracic single-port assisted laparoscopic transabdominal diaphragmatic approach, for Siewert type II adenocarcinoma of the esophagogastric junction

Objective: To investigate the learning curve for a five-step procedure, namely, a transthoracic single-port assisted laparoscopic transabdominal diaphragmatic approach, for Siewert type II adenocarcinoma of the esophagogastric junction. Methods: In this retrospective cohort study, we analyzed relevant clinical data of 66 patients with Siewert type II adenocarcinoma of the esophagogastric junction who had undergone the five-step procedure performed by the same surgeon in the Gastrointestinal Surgery Department of Guangdong Provincial Hospital of Chinese Medicine from May 2017 to April 2023. The learning curve were plotted using cumulative summation analysis and selected indicators, including intraoperative blood loss, duration of surgery, time to first flatus, time to first tolerance of liquid food, length of hospital stay, and incidence of perioperative complications at different stages were compared. The data were analyzed using SPSS 24.0 statistical software. Numerical data are presented as cases (%) and data were analyzed using the χ2 test or Fisher's exact test. Normally distributed measurement data are presented as x±s, and independent sample t-testing was performed for inter group comparison. Non-normally distributed measurement data are presented as M(Q1, Q3) and the Mann-Whitney U test was used for inter group comparison. Results: The five-step procedure had been successfully completed without switching to open surgery in all 66 study patients. There were no perioperative deaths, blood loss was 100 (50, 200) mL and duration of surgery 329.4±87.3 minutes. The equation of optimal fit for the duration of surgery was y=0.031x3-4.4757x2+164.97x-264.4 (P<0.001, R2=0.9797). The cumulative summation learning curve reached a vertex when 25 surgical procedures had accumulated. Using 25 cases as the cut-off, we divided the learning curves into learning and proficiency periods and patients into learning (25) and proficiency period groups (41). There were no statistically significant differences between the two groups of patients in sex, age, body mass index, American Society of Anesthesiologists score, history of abdominal surgery, comorbidities, preoperative neoadjuvant therapy, maximum tumor diameter, surgical procedure, or T and N stage of tumor (P>0.05). The following factors differed significantly (all P<0.05) between the learning and proficiency stages: in the latter there was less intraoperative blood loss (100 [50, 100] ml vs. 200 [100, 200] ml, U=-3.940, P<0.001), shorter duration of surgery ([289.8±50.7] minutes vs. [394.4±96.0] minutes, t=5.034, P<0.001), more mediastinal lymph nodes removed (5 [2, 8] vs. 2 [1, 5], U=-2.518, P=0.012), earlier time to first flatus (2 [2, 3] days vs. 4 [3, 6] days, U=-4.016, P<0.001), earlier time to first tolerance of liquid food (5 [4, 6] days vs. 7 [6, 8] days, U=-2.922, P=0.003), shorter duration of hospital stay (8 [8, 10] vs. 10 [9, 12] days, U=-2.028, P=0.043). The incidence of surgical complications did not differ significantly between the two groups (P=0.238). Conclusion: Satisfactory results can be achieved with the five-step procedure for patients with Siewert type II adenocarcinoma of the esophagogastric junction once 25 procedures have been performed.

Pre-Operative Evaluation of Risk Factors for Difficult Laparoscopic Cholecystectomy

Cholelithiasis or the gallstone disease is the most common biliary pathology. 10-15% population of western world is estimated to be affected by gallstone disease, of which majority remains asymptomatic (&gt;80%) and 1-2 % of these asymptomatic patients will develop symptoms needing surgery per year. In this prospective study, 77 patients years undergoing elective Laparoscopic Cholecystectomy (LC) and meeting all inclusion criteria in Department of General Surgery, Nepal Medical College and Teaching Hospital over period of 1 year. History, detailed clinical examination and laboratory investigations were performed as per the working proforma. Operative time and conversion to open cholecystectomy were recorded. The association between clinical, laboratory and sonographic factors with difficult laparoscopy were obtained. Data analysis was done using SPSS-17 version. Out of 77 patients, 63 were females. Body mass index (BMI) above 30 representing obese population were 33.2% with p value 0.0004. Also, 41.5% patients had history of acute cholecystitis while 12.9% patients had previous history of abdominal surgery and 70.1% patients had history of recurrent abdominal pain. Total of 19.4% patients had increased leucocyte count. On ultrasonography thickened GB wall of &gt;3 mm was seen in 42.8%, distended GB was seen in 41.5%, stone size of &gt;1 cm was seen in 70.1% patients and multiple stones were seen in 84.4%. Similarly, duration of surgery was &gt;90 mins in 31.1% and 7.04% patients underwent conversion to open cholecystectomy both of which were considered difficult laparoscopy. Our study reveled that clinical factors like age, BMI, history of acute cholecystitis, previous history of recurrent abdominal pain and past history of abdominal surgery had significant association in prediction of difficult LC.
