Gallstone ileus is a rare complication of cholelithiasis. It is characterized by bowel obstruction secondary to gallstone impaction at some point of the gastrointestinal tract due to the existence of a bilioenteric fistula. The aim of this analysis was to evaluate our experience through a retrospective study, covering a 12-year period. It included 14 cases (10 women and 4 men) with a median age of 81 years; 11 of the patients had comorbidities. The main analytic alteration was an increase in urea (median 79 mg/dl). Diagnosis was confirmed through abdominal computed tomography in 10 cases and plain abdominal x-ray in 4. The stone was located in the jejunum in 6 cases, the ileum in 6, and the sigmoid colon in one; the mean stone size was 3 cm. There were 11 cases of cholecystoduodenal fistula, one case of cholecystocolonic fistula, and one idiopathic fistula. Two patients died, including the patient that did not undergo surgery.
