A 55-year old man presented with a gastric outlet obstruction from metastatic duodenal cancer. Given his poor performance status from malnutrition, we decided to perform an endoscopic ultrasound (EUS)-guided gastroenterostomy with a lumen-apposing metal stent (LAMS). The procedure was performed successfully utilizing nasojejunal water irrigation and free-hand deployment of a 15-mm cautery-enhanced LAMS through the antrum ([Fig. 1]). The patient was discharged the following day tolerating oral intake. He developed a biliary obstruction 1 month later and EUS-guided choledochoduodenostomy was performed. During this endoscopy, the previously placed LAMS was noted to be completely buried within the gastric wall with purulent material oozing from the embedded margin ([Video 1], [Fig. 2], [Fig. 3]). Given the concern for separation between lumens, a through-the-scope 18 mm × 6 cm long, fully covered metal stent was placed through the LAMS and oriented along the jejunal lumen. Three months later, the patient remains asymptomatic, maintaining weight and undergoing chemotherapy.

EUS-guided gastroenterostomy with LAMS is a novel and disruptive alternative procedure that may offer long-lasting patency with less stent failure [1]. Retrospective series report stent dwell and patency ranging from 126 days for malignant disease to 319 days in benign scenarios [2]. Premature buried LAMS as early as 5 weeks has also been described when placed for drainage of pancreatic fluid collections [3].

We report a case of premature buried LAMS with a potential for lumen separation, supporting the need for prospective data for this technique.
