Gastric bypass revisional surgery: percentage total body weight loss differences among three different techniques.
Langenbeck's Archives of Surgery 2024 May 5
INTRODUCTION: Suboptimal weight loss or weight regain may occur after Roux-en-Y gastric bypass (RYGB). For this reason, revisional surgery has gained increasing interest. We aimed to compare the percentage of total body weight loss (%TBWL) at one-year follow-up among three different techniques: Jejuno-jejunostomy distalization (JJD), Sleeve resection of the gastrojejunostomy and gastric pouch (SRGJP), and the combination of both (JJD + SRGJP).
METHODS: This retrospective cohort study included all patients who underwent revisional surgery after RYGB (2020-2021). The cohort was stratified by the type of revisional technique performed. Postoperative bariatric outcomes and nutritional deficiencies were compared among groups.
RESULTS: A total of 78 patients underwent revisional surgery after RYGB: JJD was performed in 8 (10.3%), SRGJP in 34 (43.6%), and JJD + SRGJP in 36 (46.1%) patients. The most common indication for surgery was weight regain, in 72 (92.3%) patients. The median lengths of the BP limbs before and after distalization, were 50 cm (IQR 40-75 cm) and 175 cm (IQR 150-200 cm), respectively. The median length of the new common limb (NCL) and total alimentary limb length (TALL) were 277 cm (IQR 250-313 cm) and 400 cm (IQR 375-475 cm), respectively. Median percentage of total body weight loss (%TBWL) at one year was 15% (IQR 15-19%) for JJD, 20% (IQR 13-26%) for SRGJP, and 21% (IQR 15- 28%) for JJD + SRGJP (p = 0.40).
CONCLUSIONS: In this study, the combined procedure (JJD + SRGJP) exhibited higher %TBWL at one year, however no statistically significant difference was identified among the three techniques.
