Investigating a rare cause of intestinal occlusion

Gallstone ileus is a rare form of mechanical intestinal obstruction caused by the passage of gallstones in the gastrointestinal lumen and is often diagnosed in elderly females. Diagnosis can be difficult due to nonspecific findings during physical examination and there are a number of options regarding surgical or endoscopic treatment. We report the rare case of a 77- year-old female patient with gastrointestinal obstruction due to a gallstone, but without a cholecystointestinal fistula. Clinicians should be aware of this rare entity especially in emergency situations, as early diagnosis and appropriate subsequent therapy in such cases is essential to reduce mortality.
