Safety of early oral intake after endoscopic ultrasound-guided hepaticoenterostomy

Abstract

Background: Techniques and devices for endoscopic ultrasound (EUS)-guided hepaticoenterostomy (EUS-HES) procedures, including EUS-guided hepaticogastrostomy (EUS-HGS) and EUS-guided hepaticojejunostomy (EUS-HJS), have been developed; however, the optimal timing to begin oral intake after EUS-HES remains unknown. This study aimed to evaluate the safety of early oral intake after EUS-HES.

Methods: We retrospectively investigated patients who underwent EUS-HES (EUS-HGS or EUS-HJS) between March 2015 and March 2022. Patients who had no problems with the results of blood tests and computed tomography examinations on the morning of day 1 after EUS-HES were classified as either the early intake group (started oral intake on day 1 after EUS-HES) or the late intake group (started oral intake on day 2 or later after EUS-HES). Patients' characteristics, procedure characteristics, and early postprocedural adverse events (within 14 days after the procedure) were compared between groups.

Results: Fifty patients were enrolled in this study. Forty-three patients had no problems with the results of examinations performed on the morning of day 1 after EUS-HES. Twenty-one patients comprised the early intake group and 22 comprised the late intake group. Adverse events that developed within 14 days after EUS-HES were not significantly different between groups (early 4.7% vs. late 9.0%; odds ratio, 0.50; 95% confidence interval, 0.0080-10.49; P = 1.00).

Conclusions: Starting oral intake on day 1 after EUS-HES did not increase postprocedural adverse events compared with starting oral intake on day 2 or later after EUS-HES.
