Single session endoscopic ultrasound-guided double bypass (hepaticogastrostomy and gastrojejunostomy) for concomitant duodenal and biliary obstruction: A case series.

Abstract

Concomitant malignant biliary and gastric outlet obstruction can be difficult to manage endoscopically with traditional endoscopic retrograde cholangiopancreatography (ERCP) and luminal stenting. Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HG) and gastrojejunostomy (GJ) are novel techniques that can relieve both obstructions in a single session. This study aims to describe the outcomes of combined, single session EUS-HG and EUS-GJ. This is a two-center retrospective study of consecutive patients who underwent same session EUS-HG and EUS-GJ. The primary outcome was technical success. Secondary outcomes included adverse events (AE), reduction in total serum bilirubin, length of hospital stay (LOS), and re-intervention rates. A total of 23 patients underwent EUS-HG and EUS-GJ (12 males, mean age 66.4years). Twenty-one were performed for malignant obstruction. Technical success was 100% and 95.6% for HG and GJ, respectively. All patients subsequently tolerated a soft diet and 72.7% (16/22) of patients had a 50% reduction in bilirubin post-procedure. The median LOS for the 17 patients who were not discharged home immediately following the procedure was 2 (range 1-20) days. There were five AEs (2 mild, 3 moderate). Only three patients required reintervention (interventional radiology-guided biliary drainage, stent exchange for a benign biliary stricture, and placement of a second stent through an occluded distal common bile duct stent) over a median follow-up of 78days. One patient with pancreatic cancer underwent successful tumor resection. Single session EUS-guided double bypass (HG and GJ) is technically feasible and safe when conducted by experienced endosonographers. Larger, comparative studies are needed.
