An unusual case of gallstone ileus within the cecum and ascending colon: a case report.

Gallstone ileus is a rare cause of intestinal obstruction. Due to long-standing inflammation of the gallbladder, fistulization can occur within nearby structures, most commonly to the duodenum or hepatic flexure of the colon. Through these fistulas, a stone can migrate and result in a small bowel obstruction or a large bowel obstruction. This case exemplifies the diagnosis and treatment of gallstone ileus, along with potential complications due to stone migration. Early recognition and treatment of gallstone ileus is important, as stone migration can lead to increased mortality with delayed diagnosis.
