Background and Objectives: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) represents an option to treat obstructive jaundice when endoscopic retrograde cholangiopancreatography (ERCP) fails. The success rate of this procedure has been shown to be very high. Up to now, plastic and self-expandable metallic stents (SEMSs) have been employed, each of them presenting some limitations. The aims of this study were to evaluate the technical and functional success rates of EUS-HGS using a dedicated biliary SEMS with a half-covered part (Giobor® stent). Methods: We retrospectively reviewed data of patients, who underwent EUS-HGS at our center, with at least 6 months of follow-up. Demographic, clinical, and laboratory data were extracted from the patient's charts and electronic records. Technical success rate was defined as the successful passage of the Giobor stent across the stomach, along with the flow of contrast medium and/or bile through the stent. Functional success rate was considered achieved when the decrease of bilirubin value of at least 25% within the 1st week was obtained. The rate of early and late complications was assessed. Results: A total of 41 patients were included (21F/20M, [mean age 66, range 45–85]). Technical success rate was obtained in 37 (90.2%) of patients. Functional success rate, analyzable in 29 patients, occurred in 65%. Between the 37 patients in whom HGS was technically feasible, 13 patients (31.7%) presented an early complication, mostly infective. At 6-month follow-up, 10/37 patients (27.0%) required a new biliary drainage (BD) and 11/37 (29.7%) died because of their disease. Conclusions: EUS-HGS using Giobor® stent is technically feasible, clinical effective, safe, and may be an alternative to percutaneous transhepatic BD in case of ERCP failure for biliary decompression.
