[Percutaneous transhepatic sphincterotomy]

The authors describe the technique employed for percutaneous transhepatic sphincterotomy as performed on 3 patients with common bile duct (CBD) stones. In all patients, previous endoscopic attempt had failed for anatomical reasons (Billroth II gastric resection or partial gastric resection with Brown anastomosis), and the ampulla could not be correctly incannulated with the sphincterotome. In all patients endoscopy was useful to check the position of the diathermic loop inserted percutaneously. Complete and immediate success was obtained in all 3 cases. No major complications occurred during transhepatic treatment. To date, 1 recurrence has been observed, and the patient has been retreated with bilioplasty. All patients were followed after 5-6 months with US, plain X-rays of the abdomen and blood tests (gamma Gt, alkaline phosphatase, and bilirubinemia). The authors suggest that percutaneous transhepatic sphincterotomy be employed electively in patients with biliary tree diseases in case the endoscopic approach failes.
