Introduction: There is a controversy in minimally invasive colorectal procedures regarding choosing optimal technique between intra-corporeal (ICA) and extra-corporeal anastomosis (ECA). Previous studies recognize the short-term benefits in right hemicolectomy with intra-corporeal approach; however, ICA can result in increased operative difficulty. The aim of this study is to understand attitudes towards teaching ICA in colorectal procedures and how this varies between subspeciality training. Methods: Active members of General Surgeons Australia were contacted through email to participate in a voluntary, unincentivized survey. Demographic details were collected and participants were asked to rate agreement for simulation-based training for increasing adoption of ICA through a Likert scale and when preferences for teaching ICA. Descriptive statistics were completed to describe frequencies and ordinal regression was completed to determine factors for Likert scale question. Results: There were 43 respondents and most participants recognized that ECA was easier to teach trainees and should be taught first. 53.5% of respondents recognized that simulation-based training would assist the adoption of ICA. Surgeons who routinely close bowel or enteric defects intra-corporeally are 354% more likely to show an interest in simulation-based training for adopting ICA, however, surgeons who are not involved in teaching trainees did not show an interest in simulation-based training. Conclusion: There is significant agreement that ECA forms the basis to learn ICA and simulation-based training would assist with the uptake of ICA. However, a multimodal approach, including expanding training avenues and providing financial incentives, would be necessary to enhance the adoption of ICA in colorectal surgery.

Background: Current rates of reported pediatric femoral hernias remain exceedingly low, with their incidence reported to be <1%. The mainstay of repair has traditionally been through an open approach, and pediatric surgeons remain reluctant to repair otherwise. Owing to its rarity, consensus regarding management remains absent. Because of this, we present a scoping review on the use of laparoscopy and minimally invasive techniques to repair pediatric femoral hernias. Methods: A scoping literature review was performed using PubMed, Embase, Scopus, and Web of Science for related articles (keywords). Full-text articles and abstracts were then reviewed for relevance using inclusion and exclusion criteria with data extracted from each piece. Results: The search identified 268 articles published from 1992 to 2023. Eleven articles met our inclusion criteria. After reviewing their content, a total of 87 patients were identified. Of these, 42 laparoscopic repairs were reported. Three primary laparoscopic surgical techniques were described, with no recurrence reported. Conclusion: Laparoscopy remains a viable tool in diagnosing and managing femoral hernias. Various technically feasible options for laparoscopy and minimally invasive techniques have been described with excellent results and limited recurrence. However, given the quality of the data, further studies are needed to investigate the long-term durability of such repairs.

Objective: To investigate the application value, feasibility, and safety of modified single-port laparoscopic surgery in the treatment of pediatric inguinal hernia. Methods: One hundred and twenty cases of children with indirect inguinal hernia admitted from 2017 to 2022 were enrolled in the Control and Observation groups, with 80 and 40 cases, respectively. They underwent traditional open high ligation of the hernia sac and modified single-port laparoscopic high ligation of the hernia sac, respectively. The operation duration, surgical incision size, intraoperative bleeding, postoperative hospital stay, first ambulation time, and hospitalization expenses were compared between the two groups, as well as the incidence of surgical complications in the two groups. Results: The surgical incision size, intraoperative bleeding, postoperative hospital stay, and first ambulation time of the Observation group were less than those of the Control group. There was no significant difference in operation duration or hospitalization expenses between the two groups. Only two cases in the Observation group showed suture knot reactions after surgery, with no incision infection, inguinal hematoma, iatrogenic cryptorchidism, etc. The overall incidence of complications in the Observation group was lower than that of the Control group. Conclusion: Modified single-port laparoscopic surgery for inguinal hernia in children has the advantages of minimal invasiveness, and enhanced recovery, along with fewer complications and recurrence, hence it is worthy of recommendation in clinical practice.

Objective: At present, the incidence of synchronous multiple primary lung cancer (SMPLC) is increasing, and the treatment is still a challenge. This study aims to investigate the appropriate surgical procedure for treating bilateral primary lung cancer simultaneously. Methods: A retrospective analysis was conducted on clinical data from 32 patients who underwent simultaneous bilateral lung cancer surgery in our team. This data included patient characteristics, pulmonary function indicators, surgical procedures, operation duration, chest tube removal time, postoperative hospital stay, and postoperative complications. Results: Out of the 32 patients, 15 were male, and 17 were female, with an average age of 56.4 ± 8.8 years. The average maximum diameter of the main and minor tumors was 1.8 ± 1.0 cm and 1.0 ± .5 cm, respectively. All surgeries were performed thoracoscopically through intercostal approach. The procedure for the minor tumor was performed first, followed by the main tumor operation after turning over. One case was converted to thoracotomy during the main tumor operation because of bleeding. Postoperative complications occurred in one patient. No instances of respiratory insufficiency or failure were observed after the operation, and there were no perioperative deaths or readmissions within 90 days. Conclusion: Simultaneous bilateral thoracoscopic surgery is deemed a secure and feasible option for eligible patients with bilateral primary lung cancer, and it is advisable to commence the operation on the minor tumor first.

Introduction: Biomedical devices implanted transabdominally have gained popularity over the past 50 years in the treatment of gastroesophageal reflux disease, paraesophageal hiatal hernia, and morbid obesity. Device-related foregut erosions (FEs) represent a challenging event that demands special attention owing to the potential of severe postoperative complications and death. Purpose: The aim was to provide an overview of full-thickness foregut injury leading to erosion associated with four types of biomedical devices. Methods: The study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). PubMed, EMBASE, and Web of Science databases were queried until December 31, 2023. Eligible studies included all articles reporting data, management, and outcomes on device-related FE. Results: Overall, 132 articless were included for a total of 1292 patients suffering from device-related FE. Four different devices were included: the Angelchik antireflux prosthesis (AAP) (n = 25), nonabsorbable mesh for crural repair (n = 60), adjustable gastric banding (n = 1156), and magnetic sphincter augmentation device (n = 51). The elapsed time from device implant to erosion ranged from 1 to 480 months. Most commonly reported symptoms were dysphagia and epigastric pain, while acute presentation was reported rarely and mainly for gastric banding. The technique for device removal evolved from more invasive open approaches toward minimally invasive and endoscopic techniques. Esophagectomy and gastrectomy were mostly reported for nonabsorbable mesh FE. Overall mortality was .17%. Conclusions: Device-related FE is rare but may occur many years after AAP, nonabsorbable mesh, adjustable gastric banding, and magnetic sphincter augmentation implant. FE-related mortality is infrequent, however, increased postoperative morbidity and the need for esophagogastric resection were observed for nonabsorbable mesh-reinforced cruroplasty.

Background: Laparoscopic sac disconnection and peritoneal closure represents an alternative to open pediatric hernia repair. We performed a retrospective review of our data to evaluate this alternative method. Materials and Methods: With REB approval, a retrospective chart review of all patients who underwent laparoscopic indirect inguinal hernia repair between June 2013 and July 2016 was conducted. Primary outcome was the recurrence rate. Secondary outcomes included length of surgery, postoperative hydrocele, and perioperative complications. Data were extracted from EPIC Hyperspace onto a standardized data extraction form. Results: A total of 243 patients were included, of which 82% were males. Age ranged from 1 month to 17 years of age. A total of 322 defects were repaired. Eighty (32%) had contralateral patent processus vaginalis. Twelve (4%) patients presented with incarceration and three (1.2%) had a direct inguinal hernia defect. Recurrence rate was 0.6% (n = 2). There were no intraoperative complications. Operative time was an average of 40 and 54 minutes for unilateral and bilateral repairs, respectively. No testicular ascents, testicular atrophy, vas deferens injury, postoperative hydroceles, and wound infections were reported. Conclusion: Laparoscopic sac disconnection and peritoneal closure of pediatric inguinal hernia is a safe, feasible method with one of the lowest reported recurrence rate among the other laparoscopic methods.

Background: Celiac axis stenosis can potentially lead to insufficient blood supply to vital organs, such as the liver, spleen, pancreas, and stomach. This condition result in the development of collateral circulation between the superior mesenteric artery and the hepatic artery. However, these collateral circulations are often disrupted during pancreaticoduodenectomy (PD), which may increase the risk of postoperative complications. Methods: A retrospective analysis was conducted on patients who underwent laparoscopic pancreaticoduodenectomy (LPD) from April 2015 to April 2023. Celiac trunk stenosis is classified according to the degree of stenosis: no stenosis (<30%), grade A (30%-<50%), grade B (50%-≤80%), and grade C (>80%). The incidence of postoperative complications was evaluated, and both univariate and multivariate risk analyses were conducted. Results: A total of 997 patients were included in the study, with mild celiac axis stenosis present in 23 (2.3%) patients, moderate stenosis in 18 (1.8%) patients, and severe stenosis in 10 (1.0%) patients. Independent risk factors for the development of bile leakage, as identified by both univariate and multivariate analyses, included body mass index (BMI) (HR = 1.108, 95% CI = 1.008-1.218, P = .033), intra-abdominal infection (HR = 2.607, 95% CI = 1.308-5.196, P = .006), postoperative hemorrhage (HR = 4.510, 95% CI = 2.048-9.930, P = <0.001), and celiac axis stenosis (50%-≤80%, HR = 4.235, 95% CI = 1.153-15.558, P = .030), and (>80%, HR = 4.728, 95% CI = .882-25.341, P = .047). Celiac axis stenosis, however, was not determined to be an independent risk factor for pancreatic fistula (P > 0.05). Additionally, the presence of an aberrant hepatic artery did not significantly increase the risk of postoperative complications when compared with celiac axis stenosis alone. Conclusion: Severe celiac axis stenosis is an independent risk factor for postoperative bile leakage following LPD.

Background: During the management of patients with hydronephrosis, a possibility of retrocaval ureter (RCU) may emerge indicated by a fish-hook sign or its mimickers. Owing to infrequent incidence, the proper way to diagnose or exclude an RCU is challenging and has not been discussed previously. Methods: The aim of this study was to retrospectively evaluate the children who were suspected to have an RCU during management for urinary tract dilation. An RCU may be missed or misdiagnosed owing to rare incidence. Results: The children with urinary tract dilation in whom RCU was considered are enrolled in the study (n = 13). The demographics of the patients, findings suggesting RCU, evaluation process, management, and final diagnosis are retrospectively evaluated. The final diagnosis of the patients was RCU (n = 4), ureteropelvic junction obstruction (UPJO) (n = 7), and duplicated collecting system (n = 2). An RCU was confirmed or excluded by ultrasonography (US) while there was a stent in the ureter in 6 patients and by laparoscopic exploration in the other 7 patients. Four underwent correction for RCU, 7 for UPJO, 1 for reflux, and 1 ureterocele puncture. Conclusion: The fish-hook sign is a rare conflicting radiological finding that can be encountered in imaging studies. This uncommon finding needs confirmation or exclusion of a possible RCU as missed cases manifested after failed pyeloplasty or ureteroneocystostomy were reported. Radiological evaluation (by US or cross-sectional studies) while there is a stent in the ureter is the most satisfactory radiological technique to confirm or exclude an RCU. Alternatively, being aware of a possible RCU and performing a more extensive dissection may be necessary during surgery to confirm or exclude it. If available, laparoscopy may provide this goal in a minimally invasive manner with superior visualization.

Background: The treatment of choledocholithiasis with nondilated common bile duct (CBD) is a challenge for surgeons who often choose endoscopic retrograde cholangiopancreatography with laparoscopic cholecystectomy (LC) staging surgery instead of simultaneous laparoscopic CBD exploration with LC because of the small CBD diameter. This study aims to introduce and assess the clinical applicability of a technique we developed to identify and extract CBD stones using laparoscopic ultrasound (LUS). Methods: We retrospectively reviewed surgical procedures and clinical data of 13 patients who underwent LC and CBD exploration using LUS between May 2022 and August 2023. The cystic duct was used for CBD stone removal. Results: Ten patients were successfully treated; 2 patients with residual stones were treated with ursodeoxycholic acid, whereas 1 patient required a microincision near the CBD and choledochoscopy because of stone incarceration in the duodenal papilla. The CBD diameter was 6 mm (5-9 mm). There were less than three CBD stones, with diameters of 2-6 mm; the median operative time was 105 minutes (range, 52-155 minutes). One patient developed postoperative cholangitis. The median postoperative hospital stay was 6 days (3-8 days). The stone clearance rate was 76.9%, and the CBD stone detection rate was 100%. No intraoperative complications, postoperative bile leakage, and mortality occurred. Conclusions: CBD exploration and transcystic stone extraction under LUS guidance are safe and effective approaches for patients with choledocholithiasis; strict control over surgical indications is necessary. This study could provide new strategies for effectively treating choledocholithiasis.

Background: Bronchogenic cysts result from a congenital anomalous budding of the tracheobronchial tree. Resection is usually recommended to avoid complications. Mediastinal bronchogenic cysts present a unique challenge due to their proximity to vital structures. The purpose of this study is to review our experience with mediastinal bronchogenic cysts. Methods: A single-institution retrospective review evaluated all mediastinal bronchogenic cyst excisions between January 2012 and November 2022. Patient demographics were assessed, including age at diagnosis, presenting symptoms, imaging workup, and cyst characteristics. Operative approach, complications, and surgical pathology were reported. Results: Five patients were identified. Age at diagnosis ranged from 18 to 27 months. No patient was diagnosed prenatally. All patients had symptoms at the time of diagnosis, including cough, wheezing, and respiratory distress. Three cysts were paratracheal, and two were paraesophageal. Age at surgery ranged from 26 to 30 months. All bronchogenic cysts were successfully resected thoracoscopically. Individual technical challenges included narrowing of the mainstem bronchus preventing lung isolation, significant mediastinal inflammation, the necessity for cyst evacuation to delineate the extent of the cyst, adherence of cyst wall to bronchus or trachea requiring cold dissection, and a stalk of tissue with an intimate connection to the carina that was amputated. No intraoperative or postoperative complication occurred. Surgical pathology was consistent with a bronchogenic cyst in all cases. Median length of hospital stay was two days. Conclusion: Thoracoscopy is a safe and effective procedure for mediastinal bronchogenic cyst excision in children. Certain technical maneuvers are highlighted, which may facilitate resection.
