title: Gastric Band Removal in Revisional Bariatric Surgery, One-Step Versus Two-Step: a Systematic Review and Meta-analysis.
abstract: We aimed to systematically review the literature comparing the safety of one-step versus two-step revisional bariatric surgery from laparoscopic adjustable gastric banding (LAGB) to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). There is debate on the safety of removing the gastric band and performing revisional surgery immediately or in a delayed, two-step fashion due to potential higher complications in one-step revisions. A systematic and comprehensive search of the literature was conducted. Included studies directly compared one-step and two-step revisional surgery. Eleven studies were included with 1370 patients. Meta-analysis found comparable rates of complications, morbidity, and mortality between one-step and two-step revisions for both RYGB and SG groups. This suggests that immediate or delayed revisional bariatric surgeries are both safe options for LAGB revisions.
