6^th Global Gastroenterologists Meeting

Obesity stands as an endemic disease, affecting approximately 502 million adults worldwide. This demand has required a bariatric surgery formation and multidisciplinary teams for the obesity’s treatment. We call the learning curve, when we measure the time and number necessary to do the procedure for adaptation and training in new surgical techniques. Aim of this study was to demonstrate the learning curve of a laparoscopic bariatric surgery team in a population of western Amazonia. Between October 2010 to August 2012, 100 bariatric surgeries performed by laparoscopy were analyzed. The sample consisted of 75 female patients and 25 male. Mean age 37.7 [17-62 years]. BMI mean preoperative 41.3 [35-55 kg/m2]. The techniques used were Roux-Y gastric bypass in 76 and vertical gastrectomy in 24 patients. Surgery was performed in approximately four hours in the first 30 cases, after that, it was decreased to three hours until the 60 surgeries, fixing the two hours time to complete 100 surgeries. There was little change at the beginning; the hospitalizations were 72 hours in the first 30 cases and it was stabilized in 48 hours after. Among the complications, we quote: it had happened some bleeding in the drain in two, surgical site infection, one case, gastro-jejunal stenosis, one case, inadvertent clipping of the anterior gastric wall, in one case

and jejunum of drilling by Fouchet, in one case. All the complications happened in the first 30 cases. Our team reached the learning curve in about 30 cases of bariatric surgery by laparoscopy.
