Abstract
BACKGROUND

Intraductal papillary neoplasm of the bile duct (IPNB) is a premalignant biliary-type epithelial neoplasm with intraductal papillary or villous growth. Currently reported local palliative therapeutic modalities, including endoscopic nasobiliary drainage, stenting and biliary curettage, endoscopic biliary polypectomy, percutaneous biliary drainage, laser ablation, argon plasma coagulation, photodynamic therapy, and radiofrequency ablation to relieve mechanical obstruction are limited with weaknesses and disadvantages. We have applied percutaneous transhepatic cholangioscopy (PTCS)-assisted biliary polypectomy (PTCS-BP) technique for the management of IPNB including mucin-hypersecreting cast-like and polypoid type tumors since 2010.

AIM

To assess the technical feasibility, efficacy, and safety of PTCS-BP for local palliative treatment of IPNB.

METHODS

Patients with mucin-hypersecreting cast-like or polypoid type IPNB and receiving PTCS-BP between September 2010 and December 2019 were included. PTCS-BP was performed by using a half-moon type snare with a soft stainless-steel wire, and the tumor was snared and resected with electrocautery. The primary outcome was its feasibility, indicated by technical success. The secondary outcomes were efficacy, including therapeutic success, curative resection, and clinical success, and safety.

RESULTS

Five patients (four with mucin-hypersecreting cast-like type and one with polypoid type IPNB) were included. Low- and high-grade intraepithelial neoplasia (HGIN) and recurrent IPNB with invasive carcinoma were observed in one, two, and two patients, respectively. Repeated cholangitis and/or obstructive jaundice were presented in all four patients with mucin-hypersecreting cast-like type IPNB. All five patients achieved technical success of PTCS-BP. Four patients (three with mucin-hypersecreting cast-like type and one with polypoid type IPNB) obtained therapeutic success; one with mucin-hypersecreting cast-like type tumors in the intrahepatic small bile duct and HGIN had residual tumors. All four patients with mucin-hypersecreting IPNB achieved clinical success. The patient with polypoid type IPNB achieved curative resection. There were no PTCS-BP-related serious adverse events.

CONCLUSION

PTCS-BP appears to be feasible, efficacious, and safe for local palliative treatment of both mucin-hypersecreting cast-like and polypoid type IPNB.

Core Tip: Technical feasibility, efficacy, and safety of percutaneous transhepatic cholangioscopy-assisted biliary polypectomy (PTCS-BP) for local palliative treatment of intraductal papillary neoplasm of the bile duct (IPNB) were assessed. PTCS-BP was performed in four patients with mucin-hypersecreting cast-like type and one with polypoid type IPNB. All five patients achieved technical success, and four patients achieved therapeutic success. All the four patients with mucin-hypersecreting cast-like type IPNB achieved clinical success, and the patient with polypoid type IPNB achieved curative resection. Therefore, PTCS-BP appears to be feasible, efficacious, and safe for local palliative treatment of both cast-like and polypoid type IPNB.
