Concomitant versus Delayed Cholecystectomy in Bariatric Surgery

Abstract

Background. Obesity and weight loss after bariatric surgery have a close association with gallbladder disease. The performance and proper timing of laparoscopic cholecystectomy (LC) with bariatric surgery remain a clinical question. Objective. Evaluation of the outcome of LC during bariatric surgery whether done concomitantly or delayed according to the level of intraoperative difficulty. Methods. The prospective study included patients with morbid obesity between December 2018 and December 2019 with preoperatively detected gallbladder stones. According to the level of difficulty, patients were allocated into 2 groups: group 1 included patients who underwent concomitant LC during bariatric surgery, and group 2 included patients who underwent delayed LC after 2 months. In group 1, patients were further divided into subgroups: LC either at the beginning (subgroup A) or after bariatric surgery (subgroup B). Results. Operative time in group 1 vs. 2 was 92.63 ± 28.25 vs. 68.33 ± 17.49 ( p < 0.001 ), and in subgroup A vs. B, it was 84.19 ± 19.62 vs. 130.0 ± 31.62 ( p < 0.001 ). One patient in each group (2.6% and 8.3%) had obstructive jaundice, p > 0.001 . In group 2, 33% of asymptomatic patients became symptomatic for biliary colic p > 0.001 . LC difficulty score was 2.11 ± 0.70 vs. 5.66 ± 0.98 in groups 1 and 2, respectively, p < 0.001 . LC difficulty score decreased in group 2 from 5.66 ± 0.98 to 2.26 ± 0.78 after 2 months of bariatric surgery, p < 0.001 . Conclusion. Timing for LC during bariatric surgery is challenging and should be optimized for each patient as scheduling difficult LC to be performed after 2 months may be an option.

Unpredictable Malnutrition and Short-Term Outcomes after Single Anastomosis Sleeve Ileal (SASI) Bypass in Obese Patients

“…According to a study by Elgohary et al in 2021, the incidence of gallstones (GS) was higher in patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) (50%) and minigastric bypass (MGB) (40%) compared to laparoscopic sleeve gastrectomy (LSG) (18.8%) and single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SASI) (33%) [21]. Tis suggests that certain types of weight loss surgery may be associated with a higher risk of developing GS than others.…”

“…Tis suggests that certain types of weight loss surgery may be associated with a higher risk of developing GS than others. Also, SASI has shown to be effective in improving hypertension when compared to RYGB and SG [21,22].…”
