Purpose
Although endoscopic naso-biliary drainage (ENBD) is a popular preoperative biliary drainage (PBD) method for patients with perihilar biliary malignancy (PHBM), patient discomfort caused by the nasal tube remains a problem. This study aimed to analyze the safety and efficacy of PBD with the placement of a plastic stent above the papilla [inside-stent (IS)] as a bridging therapy.
Methods
The outcomes of 78 patients with potentially resectable PHBM, of whom 29 underwent IS placement and 49 underwent ENBD were evaluated.
Results
The stent-associated complication rates were not different between the two groups (7% in the IS group and 10% in the ENBD group, P = 0.621). Catheter dislocation occurred less frequently (0% vs. 22%, P = 0.016), and the median time to recurrent biliary obstruction was longer (not reached vs. 32 days, P = 0.039) in the IS group than in the ENBD group. Among the patients who underwent resection, their postoperative severe complication rates were not substantially different (26% vs. 25%, P = 0.923).
Conclusion
IS placement is a possible alternative to ENBD as a bridge to a definitive operation for patients with resectable PHBM and a prospective trial to prove its feasibility and safety is therefore warranted.
