RESUMEN
INTRODUCTION AND AIMS: Laparoscopic sleeve gastrectomy (LSG) is the most widely performed bariatric surgery worldwide but complications and failed procedures are on the rise. AIMS: To determine the reasons for failed LSGs and report the results of conversion to gastric bypass surgery, comparing the outcomes with those of primary gastric bypass surgery. MATERIALS AND METHODS: Patients with failed LSG that underwent conversion to gastric bypass surgery through a robotic-assisted and laparoscopic (hybrid) technique were evaluated. Outcomes and follow-up related to weight loss failure (WLF) were compared with those in patients that underwent primary laparoscopic gastric bypass (pLGB) surgery. RESULTS: Revisional surgery was performed on 13 patients due to WLF, on 3 patients because of refractory gastroesophageal reflux disease (GERD), and on 2 patients due to gastric stricture. There were no differences between the preoperative characteristics of the patients with WLF before undergoing conversion to gastric bypass and the patients that underwent pLGB surgery. At postoperative month 36, the percentage of excess weight loss was greater in the patients that underwent pLGB surgery, than in those with WLF that underwent conversion to gastric bypass (69.17±23.73 vs. 54.17±12.48, respectively; P<0.05). Refractory GERD, symptoms due to gastric stricture, and comorbidities all improved after the revisional surgery. CONCLUSION: Revisional surgery resulted in acceptable weight loss at 36 months of follow-up and favored comorbidity remission. In addition, it resolved symptoms of refractory GERD and gastric stricture.

INTRODUCTION: Bilioenteric fistulas are the abnormal communication between the bile duct system and the gastrointestinal tract that occurs spontaneously and is a rare complication of an untreated gallstone in the majority of cases. These fistulas can cause diverse clinical consequences and in some cases be life-threatening to the patient. AIM: To identify the incidence of bilioenteric fistula in patients with gallstones, its clinical presentation, diagnosis through imaging study, surgical management, postoperative complications, and follow-up. MATERIALS AND METHODS: A retrospective study was conducted to search for bilioenteric fistula in patients that underwent cholecystectomy at our hospital center due to cholelithiasis, cholecystitis, or cholangitis, within a 3-year time frame. RESULTS: Four patients, 2 men and 2 women, were identified with cholecystoduodenal fistula. Their mean age was 81.5 years. Two of the patients presented with acute cholangitis and 2 presented with bowel obstruction due to gallstone ileus. All the patients underwent surgical treatment and the diagnostic and therapeutic management of each of them was analyzed. CONCLUSIONS: The incidence of cholecystoduodenal fistula was similar to that reported in the medical literature. It is a rare complication of gallstones and its diagnosis is difficult due to its nonspecific symptomatology. It should be contemplated in elderly patients that have a contracted gallbladder with numerous adhesions.
