Reoperation After Loop Duodenojejunal Bypass with Sleeve Gastrectomy: A 9-Year Experience

Loop duodenojejunal bypass with sleeve gastrectomy (LDJBSG) is effective for weight loss and resolution of obesity-related associated medical problems. However, a description of the reoperative surgery following LDJBSG is lacking.

In this retrospective study, we analyzed the surgical complications and reoperation (conversion or revision) following LDJBSG from 2011 to 2019 in a single institution.

A total of 337 patients underwent LDJBSG during this period. Reoperative surgery (RS) was required in 10LDJBSG patients (3%). The mean age and BMI before RS were 47 ± 9 years and 28.9 ± 3.6 kg/m², respectively. The mean interval between primary surgery and RS for early (n = 5) and late (n = 5)complications was 8 ± 11 days and 32 ± 15.8 months, respectively. The conversion procedures were Roux-en-Y gastric bypass(n = 5), followed by Roux-en-Y duodenojejunal bypass (n = 2) and one-anastomosis gastric bypass (n = 1); other revision procedures were seromyotomy (n = 1) and re-laparoscopy (n = 1). Perioperative complications were observed in four patients after conversion surgery such as multiorgan failure (n = 1), re-laparoscopy (n = 1), marginal ulcer (n = 1), GERD (n = 1), and dumping syndrome (n = 1).

LDJBSG has low reoperative rates and conversion RYGB could effectively treat the early and late complications of LDJBSG. Because of its technical demands and risk of perioperative complications, conversion surgery should be reserved for a selected group of patients and performed by an experienced metabolic bariatric surgical team.
