Percutaneous-endoscopic biliary stenting in patients with occluded surgical bypass.

Purpose: The purpose of this investigation was to test the feasibility of using a recently developed technique of placing internalized biliary stents into patients who have had reobstruction after initial surgical bypass.

Patients And Methods: Seven men and three women, 46 to 85 years of age (eight with pancreatic carcinoma, one with metastatic colon, and one with metastatic ovarian carcinoma), all had reobstruction after initial surgical bypass palliation. Subsequent attempts to place stents via endoscope failed in five patients; a pair of 7-Fr stents placed in one patient failed to drain well. Endoscopic stenting in four patients was not even attempted because of severely distorted anatomy. Nine of the 10 patients then had successful internal stent placement by a combined percutaneous-transhepatic and peroral-endoscopically guided technique.

Results: One of these nine placeable stents failed to drain well and the patient died 8 days later with massive tumor. Seven showed a significant decrease in bilirubin levels and improved quality of life. Two of these had sepsis that responded to antibiotics. Life span ranged between 11 days and 10 months, with one patient still alive; no deaths were directly due to stents.

Conclusion: A combined transhepatic-peroral technique of placing internalized biliary stents can be expected to result in repalliation in a majority of patients with reobstruction after earlier surgical bypass and in whom subsequent attempts at endoscopic placement of stents have failed or in whom tumor growth prevents undertaking the endoscopic approach.
