[Mechanical occlusion of the small intestines by gallstones. Our experience].

The authors report their experience of biliary ileus, namely 8 cases out of 533 intestinal occlusions of the small bowel operated from 1982-1994. The patients included 5 women and 3 men with a F/M ratio = 1.7. Mean age was 79 years. Past medical history involving the biliary tract was only recorded in 3 cases. At the time of hospitalization occlusive symptoms had been present for between 2 and 7 days: pain in 7 patients, abdomen closed to gas and feces in 6, and vomiting in 7. Direct abdominal X-ray was only performed in 3 cases. A diagnosis of intestinal occlusion was made in 6 cases and biliary ileus in 2. During surgery it became clear that the occlusion was primarily localized at the level of the terminal ileum. Cholecysto-duodenal fistula was present in 5 cases. Enterolithotomy alone was performed in 5 cases. In 4 patients postoperative progress was normal leading to recovery. Two patients died: one immediately after surgery and the other on day 12. In conclusion, the authors confirm the increasingly frequent presence of cholecysto-duodenal fistula and the increasing age of patients, with a prevalence of females. They also emphasize the importance of an early diagnosis, supported by direct abdominal radiography so that surgery can be performed as rapidly as possible. Lastly, the need to perform cholecystectomy at a subsequent date is underlined.
