Revisional surgery after sleeve gastrectomy
Sleeve gastrectomy is currently considered as a primary bariatric surgery. This is due to its relative simplicity and satisfactory results. As observed with other bariatric procedures, surgeons are confronted with insufficient weight loss or weight regain, insufficient resolution of metabolic disorders and intractable severe reflux.
Aim. The aim of this study was to analyze the indications for and the outcomes of revisional surgery after sleeve gastrectomy.
Material and Methods. From 2011 to 2017, 11 (5%) patients underwent revision surgery after sleeve gastrectomy procedure for insufficient weight loss and/or severe reflux. All patients with failure after primary sleeve gastrectomy underwent endoscopic and radiologic evaluation. The patients were subdivided into groups: group 1, undergoing revision as part of a two-step procedure; group 2 with failure of a primary sleeve gastrectomy (insufficient weight loss and/or severe reflux).
Results and Discussion. Mean initial body mass index and excess weight were 47,7±10,1 (35-81,5) kg/m2 and 76,8±32,6 (46-169) kg, respectively, before primary sleeve gastrectomy. The mean interval between the two procedures was almost 23±9,2 months in group 1 and 43±27,4 months in group 2. The mean body mass index and % excess weight loss was 49,7±7,1 kg/m2 and 34,2±15,7 % for group 1 and 37,2±3,0 kg/m2 and 18,9±11,9% for group 2, before revisional surgery. Five patients underwent a two-step procedure because of extreme obesity in grou p 1. In group 2: three patients underwent conversion to Roux-en-Y gastric bypass for insufficient weight loss and severe reflux, and three patients underwent re-sleeve gastrectomy for insufficient weight loss and severe reflux. All reflux symptoms were resolved postoperatively without medication. The mean body mass index and % excess weight loss was 30,4±4 kg/m2 and 68,8±11,3 % for group 1 and 27,7±5,4 kg/m2 and 62,1±20,6% for group 2, respectively. The only postoperative complication observed was a staple line leakage. Revision-related mortality was 0 %.
Conclusion. The revision rate was 5%. Revision of a sleeve gastrectomy is safe, feasible and effective in the short term follow-up in patients who do not achieve sufficient weight loss and in those patients who have sever reflux after the initial sleeve gastrectomy.
