Meckel’s Diverticuli are remnants of the vitelline duct which totally obliterate during the 9th week of gestation in 98% of the population. Of the other 2% which retain a remnant of the duct, only a small proportion goes on to develop complications that need surgery. Gallstone ileus is an obstruction typically unrelated to Meckel’s Diverticuli which results from inflammation and fistulization of the gallbladder to the small bowel or stomach with subsequent passage of a large stone. This case report describes a unique occurrence in which a gallstones ileus led to acute Meckel’s diverticulitis. The approach to gallstone ileus should generally be enterotomy with stone extraction alone, while Meckel’s Diverticulitis is treated with resection and primary anastomosis. When faced with concurrent diseases, stone extraction for a gallstone ileus can be performed after transecting the small bowel for resection of the Meckel’s and prior to performing the anastomosis.
