Gallstone ileus in patient with Crohn's disease: report of a clinical observation.

Gallstone ileus is an uncommon form of bowel obstruction, related in the majority of cases to a cholecystoenteric fistula. In patients with Crohn's disease the stone can obstruct the diseased bowel. We report a case of gallstone ileus in a patient with Crohn's disease. An explorative laparoscopy and a minimally-invasive laparotomy were achieved to resolve the obstruction. Cholecystectomy and closure of the cholecystoduodenal fistula were not performed. The association of gallstone ileus and Crohn's disease is very rare; only few cases are reported in the literature. Laparoscopic approach could identify the extension of the disease and the site of impaction, allowing the differential diagnosis in particular in patients with Crohn's disease. In the cases described, cholecystectomy and the closure of the fistula were not performed considering the absence of any residual stone in the gallbladder and the associated risk of treating the cholecysto-duodenal fistula in an emergency settings.
