The aim of this study was to present our experience of a series of patients with CEF, presenting with or without gallstone ileus, along with their surgical outcomes. Methods: From 2015 to 2018, 3245 consecutive patients underwent cholecystectomy for gallbladder disease at our institution, of which 15 were diagnosed with a CEF. All electronic medical records were retrospectively reviewed. Results: Fifteen patients presented with CEF. Ten patients presented cholecystoduodenal stula, four pa- tients cholecystocolonic, and one patient cholecystogastric counterparts. Twelve patients were female. The median patient age was 61 years (range 33 86 years). Five patients presented with gallstone ileus treated by laparotomy and enterolithotomy. In ten patients, a laparoscopic approach was attempted, but conversion to open surgery was necessary for eight of them. The median operative time was 140 min (range 60 240 min), and the median operative blood loss was 50 mL (range 10600mL). The procedure-related morbidity and mortality rates were 13.3% and 6.7%, respectively. Conclusions: There is no consensus on the best treatment modality for a CEF, as the treatment outcome is mostly dependent on the surgeon’s expertise and the patient’s condition. Not all CEFs are accompanied by gallstone ileus. For such case, the main purpose is to resolve the intestinal obstruction and, unless necessary, avoidance of the gallbladder area.展开更多
