Abstract
Background and Aims
Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) may be a feasible and useful alternative in patients with malignant biliary obstruction (MBO) after failed endoscopic retrograde cholangiopancreatography (ERCP). To date, the risk factors for adverse events (AEs) and long-term outcomes of EUS-HGS have not been fully explored according to stent type. Therefore, we evaluated potential risk factors for AEs and long-term outcomes of EUS-HGS.
Methods
In total, 120 patients who underwent EUS-HGS were retrospectively reviewed. A multivariate analysis through Cox proportional hazard and logistic regression model was used to identify the risk factors for stent dysfunction and AEs, respectively. Stent patency and patient survival were evaluated using Kaplan–Meier plots with a log-rank test for each stent.
Results
The technical and clinical success rates were 96.2% (102/106) and 83.0% (88/106). The median duration of stent patency was longer in self-expandable metal stents (SEMS) compared to plastic stents (PS) (158 vs. 108 days). Kaplan–Meier analysis indicated that the type of stent was not associated with stent patency (Hazard ratios [HR] 0.997, 95% confidence interval [CI] [0.525–1.896]) or overall survival. In addition, multivariate analysis indicated that hilar MBO significantly associated with stent dysfunction (HR, 2.340; 95% CI, 1.028–5.326, p = 0.043) and late AEs.
Conclusions
Given the lower incidence of AEs and better long-term outcomes of EUS-HGS, it can be considered a safe alternative to ERCP or percutaneous approaches regardless of which stent is used. Furthermore, hilar MBO was established as a potential risk factor for stent dysfunction and late AEs.
