Laparoscopic minigastric bypass as a revisional choice for failed restrictive bariatric procedure and its metabolic impact

Background
Restrictive bariatric procedures, like laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG), are associated with an increased risk of long-term failure. The efficacy of One-anastomosis gastric bypass (OAGB) has been described in primary and revisional settings, with a lack of Egyptian studies regarding OAGB as a revisional surgery. Herein, we describe our experience regarding 1-year outcomes of OAGB as a revisional surgery after failed LSG or LAGB.
Patients and methods
Fifty patients with failed LSG or LAGB were enrolled in this prospective study. All cases underwent laparoscopic OAGB, and its effects on weight loss and obesity-related comorbidities were noticed after 3, 6, and 12 months.
Results
The duration of the operation ranged between 45 and 120 min Postoperative complications included leakage (2%), hemorrhage (2%), and port site infection (2%). OAGB as a revisional surgery led to a significant and effective weight loss, as the percent of excess weight loss (%EWL) had mean values of 23.72%, 51.54%, and 80.25% at the scheduled visits, respectively. The procedure was associated with a significant rise in hemoglobin and albumin, significant decline in blood sugar, glycosylated hemoglobin, vitamin B12, and most lipid profile parameters, with no significant changes in serum calcium and high-density lipoproteins. Beneficial effects (remission or improvement) were noticed in 88.9% of diabetic cases, 80% of hypertensive cases, and 100% of reflux cases at one-year follow-up visit.
Conclusion
Laparoscopic OAGB as a revisional surgery is a safe and efficacious procedure in the management of patients with failed previous restrictive procedures like LSG and LAGB.
