As LCBDE can be technically challenging to perform, utilizing a disposable single-use cholangioscope (DSUC) for LCBDE through a cystic ductotomy has several advantages, such as potentially avoiding a choledochotomy and expanding access to cholangioscopes as a DSUC is disposable and does not require infrastructure for cleaning or maintenance. <b><i>Methods:</i></b> An IRB-approved, retrospective chart review from 2021 to 2023 was conducted for patients who underwent concurrent laparoscopic cholecystectomy (LC) and LCBDE with a DSUC (SpyGlass™ Discover, Boston Scientific, Natick, MA) for the management of choledocholithiasis diagnosed either preoperatively or during intraoperative cholangiogram (IOC).

Methods: We retrospectively reviewed 145 cases of LC operated by two residents under indocyanine green (ICG)-guided mode or normal LC procedures to illustrate the role of ICG mode in boosting the LC learning curve. The clinic data were analyzed by logistic regression, receiver operator curve tests, Cumulative Sum (CUSUM), and Risk-Adjusted Cumulative Sum (RA-CUSUM) analysis. Results: The operation failure rate is similar. However, operation time under ICG mode is shorter than that under normal mode. The peak at the 49th case represented the normal resident's complete mastery of the surgery, while the peak point of ICG mode appeared at the 36th case in the fitting curve. The most significant cumulative risk (peak point) of operation failure of LC was at the 35th case in ICG LC mode, while it appeared in the 49th in normal LC mode.

This study aimed to evaluate the impact of the COVID-19 lockdown on weight loss trajectories (WLT) and perioperative outcomes in primary bariatric surgery at a single tertiary referral center. Methods: Patients who underwent primary bariatric surgery immediately prior to the enforced lockdown (During-Lockdown Group, DLG) were compared with historical controls who underwent surgery before the lockdown (Before-Lockdown Group, BLG). WLT were estimated using a random intercept mixed-effects model with repeated measures. Cross-sectional group differences at 3- and 6-months post-surgery were examined. Perioperative outcomes were also analyzed. Results: A total of 273 patients were included (133 BLG, 140 DLG). The adjusted average weight decreased in both groups over time at different levels. The expected difference in weight between BLG and DLG at 3-months was 1.06 kg (P = .013) and at 6-months was .04 kg (P = .920), respectively. There were no statistically significant differences in postoperative complications, emergency department visits, re-admission rates, re-operation rates, or mortality. Conclusions: This study suggests that bariatric procedures performed before the COVID-19 lockdown were effective and safe. Despite a statistically significant difference in weight between groups at 3- and 6-months post-surgery, the difference was small and unlikely to be clinically significant.
