Background: Surgical gastrojejunostomy and enteral self-expanding metal stents are efficacious for the management of gastric outlet obstruction but limited by high complication rates and short-term efficacy. Endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) is a novel alternative option. Patients and methods: Patients who underwent EUS-GJ between March 2014 and September 2015 as part of a prospective multicenter registry at four academic centers in two countries were included. Technical success was defined as successful placement of a gastrojejunal lumen-apposing metal stent. Clinical success was defined as the ability of the patient to tolerate an oral diet. Post-procedural adverse events were recorded. Results: The study included 26 patients, of whom 11 (42 %) were male. Technical success was achieved in 24 patients (92 %). Clinical success was achieved in 22 patients (85 %). Of the 4 patients in whom clinical success was not achieved, 2 had persistent nausea and vomiting despite a patent EUS-GJ and required enteral feeding for nutrition, 1 died before the initiation of an oral diet, and 1 underwent surgery for suspected perforation. Adverse events, including peritonitis, bleeding, and surgery, occurred in 3 patients (11.5 %). Conclusion: EUS-GJ is an emerging procedure that has efficacy and safety comparable with those of current therapies and should hold a place as a new minimally invasive option for patients with gastric outlet obstruction.Clinical trial identification number: NCT01522573

LAMS migration occurs in 1 out of 7 cases and is most common when treating PFCs. Bleeding related to LAMS placement occurs much less commonly but can be life-threatening.

AIMTo investigate technical feasibility, outcomes and adverse events of the lumen-apposing metal stent (LAMS) for benign gastrointestinal (GI) tract strictures.METHODSBetween July 2015 and January 2017, patients undergoing treatment by LAMS for benign GI strictures at three tertiary referral centers were included in this study. Primary outcomes included technical success, short-term clinical success, long-term clinical success, and adverse events. Short-term clinical success was defined as symptom resolution at 30 d after stent placement. Long-term clinical success was defined by symptom resolution at 60 d in patients who continued to have indwelling stent, or continued symptom resolution at 30 d after elective stent removal.RESULTSA total of 21 patients (mean age 62.6 years, 47.6% males) underwent placement of LAMS for benign GI strictures. A 15 mm × 10 mm LAMS was placed in 16 patients, a 10 mm × 10 mm LAMS was placed in 2 patients, and a 16 mm × 30 mm LAMS was placed in 3 patients. Technical success was obtained in all cases. Short-term clinical success was achieved in 19 out of 21 cases (90.5%), and long-term clinical success was achieved in 12 out of 18 (66.7%). Mean (range) stent indwell time was 107.2 (28-370) d. After a mean (range) dwell time of 104.3 (28-306) d, 9 LAMSs were removed due to the following complications: ulceration at stent site (n = 1), angulation (n = 2), migration (n = 4) and stricture overgrowth (n = 2). Migration occurred in 4 cases (19.0%), and it was associated with stricture resolution in one case. Median (range) follow-up period was 119 (31-422) d.CONCLUSIONUtilization of LAMS for benign strictures has shown to be technically feasible and safe, but adverse events highlight the need for further study of its indications.
