Abstract
VELEZ, José Pablo; ARIAS, Rafael and GOMEZ, Santiago. Reoperations in bariatric surgery, conversion to a different type of procedure. rev. colomb. cir. [online]. 2011, vol.26, n.1, pp.42-47. ISSN 2011-7582.
Background: This study evaluated the safety and efficacy of the laparoscopic approach in performing reoperations for failed bariatric surgery, and the assessment of the results of conversion to the another type of procedure. Methods: We studied 27 patients in the period August 2002 to February 2008 at Fundación Valle del Lili in Cali, Colombia. The type of revisional surgery was determined by the group of bariatric surgeons, according to the previous procedure, alimentary habits, symptoms, and characteristics of each patient. We evaluated operative time, complications, mortality and morbidity, improvement of the patients´ comorbidities, and post reoperation weight loss. Results: 27 patients had revisional bariatric surgery. The mean age was 44 years (range 26 to 71), 19 were women (70%) and 8 men (30%). Mean follow up was 19 months (range 2 to 60 months). The mean body mass index (BMI) before reoperation was 41 kg/m² and after revisional surgery reached 32 kg/m². Bariatric operations before revisional surgery were: mini gastric bypass (1), adjustable gastric band (n=9. 33%), vertical banded gastroplasty (n=1. 4%), non-adjustable gastric band (n=14.52%), and gastric bypass (n=2.7%). The revisonal procedures performed were: sleeve gastrectomy in 3 patients (11%), gastric bypass in 14 patients (52%), biliopancreatic diversion in 9 patients (33%) and elongation of loop in one patient (4%). The average operating time was 237 minutes (range 110 to 580). Conclusion: reoperations for bariatric surgery should be performed by a group of surgeons with wide experience in bariatric surgery and minimally invasive surgery. They are technically more demanding procedures.
