Abstract: The gallstone ileus is a serious complication of cholelithiasis due to the formation of a fistula from the gallbladder to the subjacent duodenum. The gallstones are usually large enough to cause intestinal obstruction. The distal ileum, close to the ileocecal valve, is the most common site of obstruction in these cases, where the luminal diameter is narrowed. This condition is currently responsible for 4% of all the cases of mechanical bowel obstruction. However, when considering a 65+ age group, the rate goes up to 25%. In conclusion, gallstone ileus is a surgical emergency that, although rare, has high morbimortality rates. We present the case of a patient with an acute abdomen. Exploratory laparotomy was performed with Cholecystoduodenal Fistula repair in 1st part of duodenum with cholecystectomy. The postoperative evolution was satisfactory without complications.
