Background: For patients in whom laparoscopic adjustable gastric band has failed, conversion to Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy are both options for further surgical treatment. There are limited data comparing these 2 procedures. The National Bariatric Surgery Registry is a comprehensive United Kingdom-wide database of bariatric procedures, in which preoperative demographic characteristics and clinical outcomes are prospectively recorded.
Objectives: To compare perioperative complication rate and short-term outcomes of patients undergoing single-stage conversion of gastric band to Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy.
Setting: United Kingdom national bariatric surgery database.
Methods: From the National Bariatric Surgical Registry data set, we identified 141 patients undergoing single-stage conversion from gastric band to either gastric bypass (113) or sleeve gastrectomy (28) between 2009 and 2014, and analyzed their clinical outcomes.
Results: With respect to perioperative outcomes gastric bypass was associated with a higher incidence of readmission or reintervention postoperatively (16 versus 0; P = .04). There was no difference in percentage excess weight loss between sleeve gastrectomy and gastric bypass at final follow-up at 1 year (52.1% versus 57.1% respectively; P = .4).
Conclusions: Conversion from band to sleeve or bypass give comparable good early excess weight loss; however, conversion to sleeve is associated with a better perioperative safety profile.
