Colonic gallstone ileus: a systematic literature review with a diagnostic-therapeutic algorithm

AbstractRare complication of gallstone disease is gallstone ileus. The common location is the small intestine, followed by the stomach. The rarest location is colonic gallstone ileus (CGI). To summarize and define the most appropriate diagnostic methods and therapeutic options for CGI based on the paucity of published data. Literature searches of English-, German-, Spanish-, Italian-, Japanese-, Dutch- and Portuguese language articles included and Italian-language articles using PubMed, EMBASE, Web of Science, The Cochrane Library, and Google Scholar. Additional studies were identified from the references of retrieved studies. 113 cases of CGI were recorded with a male to female patient ratio of 1:2.9. The average patient age was 77.7  years (range 45–95 years). The usual location of stone impaction was the sigmoid colon (85.8%), followed by a descending colon (6.6%), transverse colon (4.7%), rectum (1.9%), and lastly, ascending colon (0.9%). Gallstones ranged from 2 to 10 cm. The duration of symptoms was variable (1 day to 2 months), with commonly reported abdominal distension, obstipation, and vomiting; 85.2% of patients had previous biliary symptoms. Diverticular disease was present in 81.8% of patients. During the last 23 years, CT scan was the most common imaging method (91.5%), confirming the ectopic gallstone in 86.7% of cases, pneumobilia in 65.3%, and cholecytocolonic fistula in 68%. The treatment option included laparotomy with cololithotomy and primary clos...
