Percutaneous transjejunal biliary intervention: 10-year experience with access via Roux-en-Y loops

Abstract

Purpose: To assess the safety and efficacy of percutaneous retrograde transjejunal cholangiography and biliary intervention for benign and malignant disease.

Materials and methods: The clinical and radiographic records of 43 patients (31 with benign and 12 with malignant disease) who had undergone percutaneous retrograde transjejunal biliary intervention over a 10-year period at a single institution were reviewed. One hundred eighty-one procedures were performed via a fixed Roux-en-Y loop and 15 via an unfixed loop.

Results: Percutaneous retrograde transjejunal cholangiography was attempted on 196 occasions (143 for benign and 53 for malignant disease). Primary successful access was obtained in 181 (92.3%). Adjunctive percutaneous transhepatic cholangiography improved successful access in an additional seven procedures, to 188 (95.9%). Interventions included stricture dilation, stone extraction, stent insertion, and brachytherapy. The mean number of biliary interventions and the mean interval between them were 3.1 interventions and 5.9 months in the benign group and 3.6 interventions and 3.8 months in the malignant group. The complication rate was 4.1%, with no deaths or episodes of biliary sepsis.

Conclusion: Percutaneous transjejunal biliary access allows repeated interventions over many years with a low morbidity. Routine superficial fixation of Roux-en-Y loops is recommended for all biliary-enteric anastomoses to allow use of this safe and effective approach for any subsequent biliary intervention.
