Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a rescue procedure when endoscopic retrograde cholangiopancreatography fails. Peritonitis and recurrent biliary obstruction (RBO) are adverse events (AEs) associated with EUS-HGS. Antegrade stenting across a malignant distal biliary obstruction (MDBO) followed by EUS-HGS (EUS-HGAS) creates two biliary drainage routes, potentially reducing peritonitis and prolonging time to RBO (TRBO). We compared the outcomes of the two techniques.
METHODS
Data of consecutive patients with MDBO who underwent attempted EUS-HGS or EUS-HGAS across five institutions from January 2014 to December 2020 were retrospectively analyzed. A matched cohort of the patients was obtained using one-to-one propensity score matching. The primary outcome was TRBO, and secondary outcomes included AEs except for RBO and overall survival (OS).
RESULTS
Among 360 patients, 283 (176 and 107 in the HGS and HGAS groups, respectively) were eligible. The matched cohorts included 81 patients in each group. AEs developed in 10 (12.3%) and 15 (18.5%) patients (p=0.38) in the HGS and HGAS groups, respectively. RBO occurred in 18 and 2 patients in the HGS and HGAS groups, respectively (p<0.001). TRBO was significantly longer in the HGAS group (median 194 vs. 716 days; hazard ratio [HR]=0.050, 95% confidence interval [CI]=0.0066-0.37, p<0.01). However, there was no significant difference in OS between the groups (median 97 vs. 112 days; HR=0.97, 95% CI=0.66-1.4, p=0.88).
CONCLUSIONS
EUS-HGAS extended TRBO compared with EUS-HGS, while AEs, except for RBO and OS, did not differ. The longer TRBO of EUS-HGAS could benefit patients with longer life expectancy.
