Efficacy and safety of sequential cutting of nasobiliary tubes as an alternative to stent placement after nasobiliary drainage for the treatment of hilar malignant biliary stricture: a retrospective cohort study.

ABSTRACT:

Background

The rising incidence of hilar malignant bile duct strictures poses challenges for diagnosis and treatment. While endoscopic treatment is essential for relieving obstruction, it carries a high risk of postoperative cholangitis. Sequential cutting of nasobiliary tubes as an alternative to stent placement after nasobiliary drainage may emerge as an effective strategy to mitigate these complications.

Objectives

This study aimed to evaluate the efficacy and safety of nasobiliary tube cutting after nasobiliary drainage versus conventional stent placement in reducing postoperative cholangitis in patients with hilar malignant biliary strictures.

Design

A retrospective cohort study.

Methods

From 2015 to 2023, 208 patients were divided into two groups: nasobil
