5-year outcomes of 1-stage gastric band removal and sleeve gastrectomy

Abstract

Background No verdict has been reached on single-stage removal of gastric banding with sleeve gastrectomy. Objectives To report 5-year outcomes of 1-stage gastric band removal and sleeve gastrectomy (Conversion-LSG) compared with primary laparoscopic sleeve gastrectomy (Prim-LSG). Setting Large single-surgeon prospective database. Methods Two patient groups were included: Conversion-LSG as the study group and Prim-LSG for comparison. Preconversion characteristics, conversion indication, weight loss, and complications were compared. The surgical protocol was reviewed, focusing on key technical recommendations. Results A total of 209 Conversion-LSG and 3268 Prim-LSG patients, aged 32.9±9.8 and 31.8±10.7 years respectively (P = .2), were studied. No significant differences in age, body mass index (BMI), or gender distribution existed. Conversion-LSG Baseline BMI was 47±12 kg/m2. Patients spent 6.2±2.6 years with the band before Conversion-LSG. BMI at 1, 2, 3, 4, and 5 years was 37±8, 31±9, 29±11, 30±9, and 30±11 kg/m2, respectively. No significant difference in BMI change between the 2 groups existed. In the Conversion-LSG group, 1 patient had a successfully stented leak but developed a gastrobronchial fistula 1 year later. In the Prim-LSG group, 3 leak cases were reported and managed successfully through endoscopic stenting, 1 patient had pulmonary embolism that responded to standard treatment, and 3 patients had postoperative bleeding. No other major complications occurred, and there was no mortality in either group. Additionally, no Conversion-LSG patients required further bariatric intervention. Conclusion Employing the surgical technique described in this paper, conversion-LSG is as well tolerated and effective as primary sleeve gastrectomy.
