The Postcholecystectomy Syndrome: Bile Ducts as Pain Trigger Zone

Abstract

Sixty-five non-icteric patients presumed to have the postcholecystectomy syndrome (PCS) were followed up for 4-13 years after their first endoscopic retrograde cholangiopancreatography (ERCP) examination, which gave normal findings. All patients, however, experienced severe pain on injection of only 1-2 ml of contrast medium over 5-10 sec into the common bile duct (CBD). Thirty-four of the 65 patients were found to have true PCS on long-term follow-up studies, whereas 31 of them had other diseases. A second ERCP also showed normal results, and the injection-related pain was preceded by an abnormal pressure rise in the CBD at manometry. The CBD acted like a pain trigger zone, and the pain reaction might be diagnostic in everyday clinical practice. In conclusion, ultrasonography is an adequate diagnostic method in non-obstructive PCS. Medical treatment is often successful. ERCP and interventional treatment should be reserved for patients with obstructive symptoms and for patients in whom all medical treatment has failed.
