BACKGROUND : This study evaluated an oroenteric catheter (OEC)-assisted technique to distend the enteric loop for endoscopic ultrasound-guided gastroenterostomy (EUS-GE) in patients with gastric outlet obstruction (GOO). METHODS : Patient outcomes were reviewed. Proximal enteric loops were filled with water via an OEC (7 Fr or 8 Fr), providing a target for EUS-GE using a lumen-apposing metal stent (15-mm caliber). Clinical success was defined as toleration of a non-liquid diet by Day 3. RESULTS : 42 patients (mean age 73.1 [SEM 2.8] years; 23 male) underwent EUS-GE for malignant (n = 37) and benign (n = 5) duodenal strictures. EUS-GE creation was successful in 41/42 (98 %), with mean procedure time of 36 (SEM 3) minutes and no serious complications. Clinical success was achieved in 39/42 (93 %) at 5.7 (SEM 2.6) months' follow-up. Of 14 patients who died, 13 (93 %) maintained oral intake until death. EUS-GE provided good symptom relief in all 28 surviving patients until follow-up. CONCLUSIONS : OEC-assisted EUS-GE provided satisfactory relief of GOO symptoms, with high technical success (98 %) and no serious complications.
