Gallstone Ileus: A Rare Cause of Mechanical Bowel Obstruction.

A gallstone ileus is a rare cause of mechanical bowel obstruction, accounting for 1% to 4% of all cases. Twenty-five percent of the patients are 65 years of age or older and often present previous significant medical conditions. The authors report the case of an 87-year-old male patient, admitted with the diagnosis of community-acquired pneumonia, who later developed frequent episodes of biliary vomiting, intermittent constipation, and abdominal distension. Abdominal imaging (ultrasound and computed tomography (CT)) showed evidence of a localized inflammatory process in a small bowel loop but excluded vesicular lithiasis. After a failure in the medical approach with antibiotics, an exploratory laparotomy was performed, identifying the intestinal occlusion area, followed by an enterolithotomy at the specific area, and extraction of a 4 cm stone of acellular material. Posteriorly, the patient was treated for three weeks with a carbapenem and physical rehabilitation was promptly initiated with full recovery of his previous status. Gallstone ileus is a very challenging diagnosis and surgery is the treatment of choice. In elderly patients, it is important to promote prompt physical rehabilitation to prevent prolonged bed rest.
