Objective: To compare the effectiveness and safety of da Vinci robot-assisted and conventional laparoscopic surgery for hiatal hernia (HH) treatment in children after repair of esophageal atresia (EA). Methods: A retrospective analysis was conducted of 54 children with EA who underwent either conventional or robot-assisted laparoscopic HH repair between January 2018 and December 2023 in our center. Clinical characteristics and postoperative outcomes were compared to explore the effectiveness and safety of both surgical methods. Results: Fifty-four patients (conventional surgery, n = 32; robot-assisted surgery, n = 22) met the inclusion criteria. No significant difference was found in gender, age, EA repair method, main symptoms, HH type, and previous HH repair between the two groups. Type A EA accounted for more proportion in conventional surgery group (43.8% versus 13.6%, P < .05). There was a higher use of Nissen fundoplication in robot-assisted surgery group (78.1% versus 100%, P < .05). No significant difference was found in terms of operation length, blood loss, time to start enteral nutrition, conversion to open and total, or postoperative length of stay. The incidence of recurrent symptoms, especially reflux during nighttime, was significantly higher in conventional surgery group (31.3% versus 0%, P < .05). No severe complication or death was reported in either group. Conclusions: Robot-assisted laparoscopic surgery can be performed safely and effectively for HH repair in EA patients, which made Nissen fundoplication more feasible and showed superior control of reflux symptoms than conventional laparoscopic surgery.

Background: Tremendous practice variation exists for placing gastrostomy tubes. The objective of this study was to determine if the operative approach is associated with 30-day complication rates. Methods: This single-center retrospective cohort study identified pediatric patients who underwent gastrostomy tube placement from June 2019 to April 2022. Gastrostomy approaches included laparoscopic, laparoscopic-assisted (incision at gastrostomy site), modified open (incision at gastrostomy site), and percutaneous endoscopic gastrostomy (PEG). Multivariable logistic regression models were performed to evaluate the association of 30-day complications and operative approach after controlling for prematurity and weight. Results: Among 521 gastrostomy patients, the median age was 10 months (interquartile range: 4-33 months), and 181 (34.9%) had a history of prematurity. Weight categories included 217 (41.6%) underweight, 272 (52.2%) normal weight, and 32 (6.1%) overweight. Patients underwent laparoscopic (n = 386, 74.1%), laparoscopic-assisted (n = 73, 14.0%), modified open (n = 33, 6.3%), and PEG (n = 27, 5.2%). Complications included reoperation (n = 17, 3.3%), readmission (n = 12, 2.3%), wound infection (n = 30, 5.8%), wound breakdown (n = 21, 4.0%), tube dislodgement (n = 23, 4.4%), granulation tissue (n = 107, 20.5%), and leakage (n = 33, 6.3%). Following adjustment, laparoscopic-assisted gastrostomy was associated with higher odds of any complication. Laparoscopic-assisted and modified open were associated with higher odds of wound breakdown. Laparoscopic-assisted and modified open were associated with higher odds of leakage. The operative approach was not associated with reoperation, readmission, wound infection, or tube dislodgement. Conclusions: Techniques for gastrostomy placement, which include an incision around the tube, were associated with higher rates of complications. To improve complication profiles for patients, surgeons should consider laparoscopic or percutaneous endoscopic gastrostomies.

Background: With improvements in skills and evidence of safety, emergent laparoscopic cholecystectomy is routinely performed for acute cholecystitis, if indicated, at our hospital. However, resident operations are concerned with the dilemmas of training programs and patient safety. Hence, our aim was to clarify the safety and feasibility of emergency laparoscopic cholecystectomy performed by attending surgeons and residents. Materials and Methods: Our study was a retrospective review of 923 patients, who underwent laparoscopic cholecystectomy between January 2021 and June 2022 at our hospital. We excluded combined surgery, single-port methods, laparoscopic common bile duct exploration, elective surgery, and patients with Mirizzi symptoms. Of the 191 patients who underwent emergency laparoscopic cholecystectomy, 118 were operated on by residents, and 73 were operated on by attending surgeons. Patient demographics, surgical and postoperative outcomes, and length of hospital stay were compared between the groups. Results: No significant differences were observed in sex, age, body mass index (BMI), or surgical history. Older age (60 versus 52 years) and higher BMI (26.29 versus 25.46) were observed in the attending group, and the severity was greater than that in the resident group. No significant differences were observed in the operative results, including mortality (both groups, n = 0), morbidity, blood loss, or length of stay. However, the operation time was significantly shorter in the attending group obviously (86.41 versus 117.89 minutes, P < .0001) significantly. Conclusion: Emergent laparoscopic cholecystectomy for acute cholecystectomy performed by a resident under supervision appears feasible and safe. The resident operator was associated with increased operative times, however, not complications. This study confirms that residents can also finish surgery in precisely selected cases, and the more important concept is knowing the limits of asking for help.

Introduction: Robotic surgery has gained acceptance in the field of pediatric surgery but is still under assessment. Some limitations of this device are particularly encountered when performing specific tasks in small cavities, such as neonatal pelvis. The aim of this study was to compare the functional results of robot-assisted anorectal pull-through (RAARP) with posterior sagittal anorectoplasty (PSARP) in children with "high" types of anorectal malformations (ARMs). Materials and Methods: In this multicenter experience, we reviewed the patients operated for ARMs using the da Vinci® system between 2007 and 2020 in our national robotic program. Two groups of patients according to the surgical technique (robotic versus open) were compared based on the postoperative outcomes and long-term functional results using Kelly and Krickenbeck scores at 3 years of age. Results: Ten patients operated using RAARP were compared with 10 patients operated using PSARP (mean weight 8.1 ± 1.2 kg versus 8.6 ± 1.1 kg, respectively). The two groups were comparable in terms of the ARM classification and patient demographics. The clinical Kelly score was significantly lower for the PSAAP group (P = .012). The Krickenbeck constipation score was significantly lower for the RAARP group (P = .02), whereas no statistical difference was found for the soiling score and voluntary bowel movements. Conclusions: A concomitant laparoscopic approach using a robotic platform appears to be an alternative technique to the criterion standard for performing anorectal malformation surgery with satisfactory functional results. The enhanced potential of preserving perirectal nerves requires confirmation through longer follow-up studies focusing on functional assessment.

Background: This study aimed to assess the impact of Enhanced Recovery After Surgery (ERAS) compliance and to identify which components of this protocol are most likely to affect postoperative outcomes in patients undergoing colorectal cancer surgery. Methods: This is a retrospective cohort evaluating patients who underwent elective colon resection. ERAS compliance was assessed based on adherence to the protocol components. The study examined the following outcomes: postoperative complications, readmission rates, mortality, conversion to open surgery, stoma creation, and length of hospital stay. Results: Of the 410 patients studied, 59% achieved ≥75% compliance. Comparison between compliance groups (<75% versus ≥75%) showed significant differences in overall complications (P = .002), severe complications (P = .001), and length of hospital stay (P < .001). The area under the receiver operating characteristic curve for predicting the absence of severe complications based on ERAS compliance was 0.677 (95% confidence interval: 0.602-0.752). Logistic regression analyses demonstrated that ERAS compliance was significantly associated with a reduced risk of severe complications (P < .001), as well as that the following items: avoiding prophylactic drains (P < .001), minimal use of postoperative opioids (P = .045), avoidance of postoperative salt and water overload (P < .001), postoperative nutritional support (P = .048), and early mobilization (P = .025). Conclusion: High ERAS compliance is associated with improved postoperative outcomes in colorectal cancer surgery. Key protocol components for preventing severe complications include avoiding prophylactic drains, minimal postoperative opioid use, avoiding salt and water overload, nutritional support, and early mobilization.

Purpose: Surgery for choledochal cysts (CDC) in children younger than 6 months is relatively rare. We report our experience and compare the results between Da Vinci robot-assisted hepaticojejunostomy (RAHJ) and laparoscopic-assisted hepaticojejunostomy (LAHJ) in children younger than 6 months to treat CDC. Methods: A retrospective study was conducted on all children under 6 months of age who underwent RAHJ or LAHJ at the Children's Hospital, Zhejiang University School of Medicine, from July 2018 to November 2023. Results: We reviewed 34 patients who underwent RAHJ surgery and 50 patients who underwent LAHJ surgery (P = .243). RAHJ group of the median operation time was 182 minutes (range 161-221), and LAHJ group was 168 minutes (range 143-191) (P = .02). The RAHJ group had a significantly shorter median postoperative hospital stay of 9 days (range 7-10) than the LAHJ group, 11 days (range 10-14), p < .001. The median hospitalization cost in the RAHJ group was significantly higher than that in the LAHJ group (75,474 CNY versus 28,984 CNY, p < .01). The median follow-up time was 18 months in the RAHJ group and 48 months in the LAHJ group (p < .01). All patients in the RAHJ group recovered well and were discharged. One patient in the LAHJ group developed biliary fistula 21 days after surgery and recovered well after reoperation. Conclusions: For children under 6 months old, on the basis of no consideration of cost, RAHJ has fast postoperative recovery and fewer postoperative complications, which is more recommended.

Background: A primary pull-through for Hirschsprung's disease (HD) requires confirmation of normal ganglionic bowel by intraoperative biopsies to determine the level of resection. Despite this, aganglionic bowel that is not fully resected (so-called "transition zone pull-throughs") is reported in 15%-19% of patients. We hypothesize that this may result from insufficient biopsies sent for intraoperative diagnosis. Methods: A new biopsy protocol has been developed in our institution for patients undergoing a laparoscopic-assisted endorectal pull-through for HD. Laparoscopic seromuscular biopsies are taken as per standard practice and are reported intraoperatively to identify the most distal site of ganglionic bowel. A 5 mm laparoscopic stapling device is used to divide the bowel at the proposed proximal resection margin and 2 cm distally. If there is any evidence of abnormality in the first doughnut, a second, more proximal doughnut is taken. Results: Between 2015 and 2020, 21 patients underwent a primary laparoscopic endorectal pull-through for HD using the doughnut biopsy protocol. Sixteen patients were male. The mean patient age at the time of surgery was 3 months (range 1-6 months), and the mean weight at the time of surgery was 6.5 kg (range 4.1-8.54 kg). In all 21 cases, initial laparoscopic biopsies were reported showing normal ganglionic bowel; in two cases (10%), the laparoscopic doughnut influenced the proximal resection margin. In both cases, aganglionic tissue was identified intraoperatively in the doughnuts, and a second, more proximal doughnut was sent. No patients had transition zone resections on final histology (mean clear margin 45.55 mm, range 11-72 mm). Conclusions: In conclusion, intraoperative frozen sections taken from doughnuts of bowel retrieved using 5 mm laparoscopic stapling devices are safe and have resulted in a 0% rate of transition zone pull-throughs while reducing the potential of spillage of enteric contents. We would recommend this protocol for all patients undergoing primary endorectal pull-throughs.

Background: The Da Vinci single-port (SP) platform is being used more frequently in radical prostatectomy (RP). In this study we aimed to compare the complications and oncological outcomes of the Da Vinci SP platform in robotic-assisted radical prostatectomy (SP-RARP) between elderly and young age-groups and to further examine differences between young-old and old-old patients. Materials and Methods: Data from 193 patients who underwent SP-RARP between December 2018 and June 2024 were analyzed. Patients were categorized into two age-groups: young (18-64 years) and elderly (65+ years). The elderly group was further divided into young-old (65-69 years) and old-old (70+ years) subgroups. The analysis considered variables related to patient characteristics, intraoperative outcomes, complications, and postoperative oncological outcomes. Results: The median age of the patients at the time of surgery was 64 (9.5) years. The intraoperative complication rate of 1.6%, with no cases requiring conversion to open surgery. The overall incidence of postoperative adverse events was 24.4%, and the 30-day readmission rate was 11.4%. Intraoperative complications and 30-day readmission rates were similar between groups (P = .593 and P = .821, respectively), while the postoperative complication rate was significantly higher in the younger patient group (P = .012). The median length of hospital stay (LOS) was 7 (22) hours and 110 (57%) patients were discharged on the same day (SDD). LOS and SDD rates were similar between groups (P = .389 and P = .529, respectively). The 3-year and 5-year biochemical recurrence (BCR)-free survival rates were 80.5% and 75.1%, respectively. The BCR-free survival rates were similar between both young and elderly patients and between the young-old and old-old groups (P = .751, P = .765, respectively). Conclusion: SP-RARP is a feasible option for elderly patients, delivering acceptable oncological outcomes with a low incidence of postoperative complications.

Background: Abdominal perineal resection (APR) remains the gold standard for lower rectal cancer involving the anal sphincter. However, the optimal patient position remains unclear. While lithotomy or Lloyd-Davies are commonly used, APR and extra-levator abdominal perineal excision (ELAPE) in a prone jackknife position have been linked to better oncological outcomes. Methods: We searched PubMed, Embase, the Central Register of Clinical Trials, and Web of Science for randomized controlled trials (RCTs) and observational studies published up to February 2024. Odds ratios (ORs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Heterogeneity was assessed using I² statistics. Statistical analysis was performed with R Software version 4.4.1. Results: Two RCTs and 26 observational studies, including 4529 patients, were analyzed. Among them, 2249 (49.7%) underwent APR or ELAPE in the prone position and 2280 (50.3%) in the supine position. The prone position was associated with reduced surgical specimen perforation (5.3% versus 9.4%; OR: 0.44; 95% CI: 0.39-0.78; P < .001), lower positive circumferential resection margins (CRMs) rates (9.8% versus 14.3%; OR: 0.69; 95% CI: 0.53-0.89; P < .001), and decreased intraoperative bleeding (mean difference: -63.7 mL; 95% CI: -104.5, -22.8; P < .01). No significant differences were observed in operative time, urinary retention, urinary injury, wound infections, perineal dehiscence, Clavien-Dindo ≥3, reoperation, local recurrence, distal recurrence, or overall survival. Conclusion: The prone position during APR is associated with reduced specimen perforation, lower positive CRM rates, and less intraoperative bleeding without significant differences in other clinical outcomes.

Background: Laparoscopic cholecystectomy (LC) is one of the most frequently performed operations in surgical practice. Despite increasing experience and technological advances, conversion to open surgery is still necessary in some cases. Although several studies have identified factors associated with increased risk of conversion, debates continue in the literature. This study aimed to evaluate the factors affecting the risk of conversion to open cholecystectomy. Materials and Methods: Patients who underwent surgery for cholelithiasis between 2020 and 2023 were analyzed retrospectively. Patients who underwent open cholecystectomy, those who had cholecystectomy as part of another surgical procedure, and patients with gallbladder malignancy (except incidental cases) were excluded from the study. Patients were analyzed based on demographic, clinical, laboratory, radiological, and histopathological data. This study was registered at ClinicalTrials.gov (NCT06244589). Results: A total of 1695 patients were included in the study. The median age was 50 years, and 66.6% of patients were female. Conversion from LC to open surgery occurred in 44 patients (2.6%). Multivariate analysis identified male sex, a history of major abdominal surgery, the need for emergency surgery due to acute cholecystitis, an elevated leukocyte count, and gallbladder wall thickening on abdominal ultrasonography as independent risk factors for conversion to open cholecystectomy. Conclusion: Male gender, previous major abdominal surgery, emergency surgery due to acute cholecystitis, high leukocyte count, and gallbladder wall thickening on abdominal ultrasonography are independent risk factors for conversion from LC to open surgery. It should be kept in mind in the treatment of patients planned for LC.
