ARTICLE HIGHLIGHTS
Research background
Currently reported local palliative therapeutic modalities, including endoscopic or percutaneous therapy to relieve mechanical obstruction, for intraductal papillary neoplasm of the bile duct (IPNB), are not efficacious due to various limitations.
Research motivation
Since 2010, we have applied percutaneous transhepatic cholangioscopy (PTCS)-assisted biliary polypectomy (PTCS-BP) technique for local palliative treatment of IPNB, including mucin-hypersecreting cast-like type and polypoid type tumors. Here we wish to share our experience including the feasibility, clinical efficacy, and safety of the technique with peer-physicians and endoscopists.
Research objectives
To assess the technical feasibility, efficacy, and safety of PTCS-BP for local palliative treatment or radical resection of IPNB.
Research methods
PTCS-BP was performed by using a half-moon type snare with a soft stainless-steel wire in four patients with mucin-hypersecreting cast-like type and one with polypoid type IPNB. The tumors were snared and resected with electrocautery.
Research results
All five patients achieved technical success of PTCS-BP. Three with mucin-hypersecreting cast-like type and one with polypoid type IPNB obtained therapeutic success; one with cast-like type tumors in the small bile duct had residual tumors. All four patients with mucin-hypersecreting IPNB achieved clinical success. The patient with polypoid type IPNB achieved curative resection.
Research conclusions
PTCS-BP appears to be feasible, efficacious, and safe for local palliative treatment of both mucin-hypersecreting cast-like and polypoid type IPNB. The new theory is that PTCS-BP can be used feasibly, efficaciously, and safely for the treatment of mucin-hyper secreting cast-like type and one with polypoid type IPNB. The novel point is that we, for the first time, applied PTCS-BP technique to treat IPNB.
Research perspectives
Our findings indicate that PTCS-BP is superior to other resection methods for the treatment of mucin-hypersecreting cast-like and polypoid type IPNB tumors. Future studies with a larger number of patients are required to confirm our findings.
