Colonic Gallstone Ileus: Treatment Challenges

Abstract

Intestinal obstruction at the level of the colon is rarely caused by a gallstone. Colonic gallstone is more frequently observed in elderly patients and is associated with high mortality due to treatment challenges. Management with less invasive approaches, including mechanical lithotripsy and endoscopy has been evolving. However, the outcomes are variable, and surgery remains the main cornerstone of treatment. We present a case of an 89-year-old male with gallstone ileus at the level of the sigmoid colon in whom treatment with endoscopy was not successful. We performed an extensive review of the literature to understand the most common presentation, diagnostic modalities, and treatment approach of the sporadic reported cases of colonic gallstone ileus.
