Sump syndrome following choledochoduodenostomy and its endoscopic treatment.

The clinical features of eight patients with 'sump syndrome' following side-to-side choledochoduodenostomy are reported. The syndrome is defined and its aetiology discussed with special reference to debris in the common bile duct, bacterial overgrowth and the clinical picture of acute cholangitis, which does not appear to be necessary for the diagnosis to be made. Five patients were successfully treated by endoscopic sphincterotomy and a sixth by endoscopic removal of food debris from the sump. The other two patients had further surgery.
