Introduction: Gastroesophageal reflux disease contributes to allograft decline secondary to bronchiolitis obliterans after lung transplantation. Antireflux surgery (ARS) slows the decline in lung function related to GERD. ARS operations range from Nissen fundoplications to partial fundoplications, such as the Toupet and Dor. Research in the general population has indicated that partial fundoplication is effective at controlling reflux. We explored lung function and reflux outcomes in a cohort of lung transplant patients who received partial fundoplications., Methods: Data from an institutional lung transplant registry was reviewed for patients between 2009 and 2020 who underwent fundoplication after transplant. Lung transplant patients underwent routine pulmonary function testing. Patients with FEV1 values within 180 days pre-fundoplication and two years post-fundoplication were included in the analysis. All patients referred for fundoplication underwent esophageal pH testing, manometry, UGI, and EGD. Most patients underwent Toupet fundoplication, but those with severe dysmotility underwent Dor fundoplication., Results: 53 patients were included in the analysis. Median time to fundoplication after transplant was 403 days. 48 patients underwent Toupet fundoplication. Five underwent Dor fundoplication. 40% of patients had abnormal high-resolution manometry. A linear mixed-effects model tested for a change in FEV1 trajectory up to two years post-fundoplication with an auto-regressive correlation structure. Post-fundoplication FEV1 values decreased by 7 mL per month, and suggested a slow in the decline by 2 mL per month, but this was not significant (p = 0.8). In patients for whom postoperative DeMeester scores were available (19), there was a decline in acid exposure from a median of 45.8 to 1.8 after ARS (p = 0.0003)., Conclusion: Although our results did not reach statistical significance, there was a trend towards a decrease in the rate of decline of allograft function before and after partial fundoplication. In the patients whom results were available, a partial fundoplication appropriately controlled acid exposure., (© 2022.

Background: The aim of the study is to determine if barium esophagram (BE) alone is sufficient to diagnose esophageal dysmotility when compared to the gold standard, high-resolution manometry (HRM)., Methods: This is a retrospective review of patients that underwent laparoscopic fundoplication by two surgeons at a single institution from 10/1/2015-6/29/2019. Patients with large paraesophageal hernias and patients without both BE and HRM were excluded., Results: Forty-six patients met the inclusion criteria. BE was found to be concordant with HRM for esophageal motility in only 21 patients (46%). Setting HRM as the gold standard, BE had a sensitivity of 14% (95% CI: 5%-35%), specificity of 72% (95% CI: 52%-86%), PPV of 30% (95% CI: 11%-60%), and NPV of 50% (95% CI: 35%-66%). The accuracy was 46%, while a McNemar test showed p = 0.028., Conclusion: Traditional BE should not be used in place of HRM for assessing pre-operative motility in patients undergoing anti-reflux surgery., (Copyright © 2020 Elsevier Inc.

Background: The ability to adequately train surgical residents in flexible and rigid endoscopy has become a difficult challenge for program directors. The American Board of Surgery requires residents to be familiar in these procedures but the methods for training have not been well defined nor formally outlined. The goals of this study were to evaluate resident experience in flexible endoscopy and laparoscopy and to investigate the specific methods used by surgical programs for the training of residents., Methods: A survey was created by the authors and the Resident Education Committee of the Society of American Gastrointestinal Endoscopic Surgeons and was mailed to all program directors in general surgery in the United States based on the data base of the Association of Program Directors in Surgery (APDS)., Results: Ninety-six of 283 surveys were returned (33.9%). The surgeon played a greater role in flexible endoscopic training in 1998 as compared to 1988 (p=0.002). When analyzed by type of institution, community programs showed a similar trend but this was not seen in academic programs. Formal endoscopy rotations existed in 60% of programs but flexible endoscopy (5.2%) and laparoscopy (10.4%) fellowships were uncommon. No significant differences in the number of advanced laparoscopic procedures performed were found between academic and community programs. The presence of a laparoscopic fellow did not significantly decrease the number of cases per resident., Conclusion: According to our survey, surgery departments have a greater impact on flexible endoscopic training in 1998 than in 1988. This is likely due to the creation of formal endoscopy rotations and the hiring of fellowship trained endoscopic instructors. In addition, community programs have been able to provide adequate experience in both basic and advanced laparoscopic techniques as compared to academic programs. As with flexible endoscopy, however, formal laparoscopic rotations may be necessary to allow more intensive experience for each resident.

Accurate identification of acute mesenteric ischemia remains a challenge. It was hypothesized that fluorescein-assisted laparoscopy (FAL) may have a role in the identification of acute arterial mesenteric ischemia. Arterial ischemic small-bowel segments were prepared in 11 dogs. Following 2.5 h of ischemia, laparoscopy was performed with a standard light source followed by FAL with an argon laser. These two techniques were immediately compared with open inspection. Standard laparoscopy correctly identified 10 ischemic segments. FAL correctly identified 9 ischemic segments and the combination of the 2 techniques allowed laparoscopy to correctly identify all 11 ischemic segments. Standard laparotomy with and without fluorescein correctly identified 10 ischemic segments. The difference between laparoscopy and laparotomy was not significant (P > 0.6, Fisher's exact test). The combination of laparoscopic evaluation with and without fluorescein allowed identification of small-bowel ischemia in all subjects in this canine model. Further studies are warranted to delineate the accuracy of laparoscopy in other patterns of mesenteric insufficiency before clinical application.

Unlabelled: Endoscopic retrograde cholangiopancreatography (ERCP) has been used to evaluate and treat pancreaticobiliary disorders and trauma in the pediatric population. Still representing a small percentage of total pediatric endoscopies, this procedure has been performed most commonly by a small subset of adult and pediatric gastroenterologists at quaternary referral centers.Methods: In this study, we present a review of one fellowship-trained general surgeon's experience with pediatric ERCP in a teaching community pediatric hospital for the purpose of comparison with national series.Results: All ERCPs performed by one general surgeon as part of a multidisciplinary team over a 5-year period in patients aged 16 years or less were reviewed. Success and complication rates were compared between our series and published pediatric and adult series using Fisher's exact test. Comparisons were made of indications, type of anesthesia, final diagnosis, and therapeutic interventions to ensure similar study populations. A total of 26 ERCPs were performed in 19 patients ranging from 7 to 16 years old. Therapeutic procedures included sphincterotomy (11), stent placement (7), stone removal (3), and dilation (2). In one case, stone removal and stent placement were performed in conjunction with pancreatic lithotripsy. In two cases the involved duct was not visualized. There were no instances of pancreatitis, bleeding, or perforation related to ERCP.Conclusions: When compared with published series, our data demonstrated no significant difference in success or complication rates. Our study demonstrates that pediatric ERCP can be performed by fellowship-trained general surgeons with success and complication rates comparable to accepted standards. Integration of the ERCP-trained general surgeon into the pediatric team is a potential asset in the care of pediatric patients with pancreaticobiliary disorders. [ABSTRACT FROM AUTHOR]
