[Ultrasonographic diagnosis of a biliary-digestive fistula with gallstone ileus]. / Sonographische Diagnose einer biliodigestiven Fistel mit Gallensteinileus.

HISTORY AND CLINICAL FINDINGS: A 72-year-old woman was admitted to the hospital with upper abdominal pain, nausea, vomiting, and obstipation. INVESTIGATIONS: Percutaneous ultrasound found aerobilia, a biliary-digestive fistula, and an ileus with gallstones within the small bowel. The findings were confirmed at computed tomography. TREATMENT AND COURSE: A gallstone ileus on the basis of a biliary-digestive fistula was diagnosed. The patient was treated by surgery and with antibiotics. CONCLUSION: This case report demonstrates that percutaneous ultrasonography should be used as the first imaging procedure in the diagnosis of acute abdominal pain. This procedure makes it possible to detect a gallstone ileus. It is important also to define various intestinal structures accurately.
