Transampullary septectomy for post-cholecystectomy pain

Abstract

Twenty-eight patients with chronic, incapacitating upper abdominal pain after cholecystectomy had excision of the common wall between the terminal bile duct and duct of Wirsung (ampullary septum). Twenty-two also had a sphincteroplasty: six had had this procedure previously. Pancreatic function studies, scintiscans, ultrasound and pancreatograms were non-diagnositic. Hyperamylasemia was an uncommon finding. Eight patients were found to have evidence of mild pancreatitis at exploration. There was gross scarring of the ampullary septum in 22 cases. Histologic examination revealed inflammation in 12 septa; the degree of fibrosis could not be assessed since 14 control septa from autopsy material free from biliary tract disease revealed a comparable degree of collagen and smooth muscle. There were no deaths, and minimal morbidity. In follow-up from seven to 59 months (mean = 26), 16 patients are relatively free of pain, five have occasional episodes which require non-narcotic analgesics, and seven have gained no relief from the operative procedure. A randomized controlled trial is recommended.
