Background Surgical gastrojejunostomy is associated with relatively high morbidity and mortality rates. However, current experimental EUS-guided gastrojejunostomy information is limited. Objective To evaluate a novel EUS-guided gastrojejunostomy technique using a new enteric balloon and lumen-apposing metal stent. Design Animal experiment. Setting Animal laboratory at a referral center. Subjects and Interventions In 5 pigs, gastrojejunostomies were created under EUS guidance. Fully covered lumen-apposing stents were placed between the stomach and the jejunum. Main Outcome Measurements Technical success and adverse events of EUS-guided gastrojejunostomy. Results All stents, with 1 exception, were successfully deployed without any adverse events. The mean time to stent placement was 44.2 minutes (range 28-64 minutes). All animals showed normal eating behavior without signs of infection for 1 month after the procedure. Endoscopic imaging of the stomach site showed the stent to be patent and stable, without dislodgment, in all of the pigs. Necropsy showed complete adhesion between the stomach and the jejunum wall. Limitations Pilot study. Conclusions Creation of an EUS-guided gastrojejunostomy by using a novel enteric balloon and metal stent appears to be promising as a minimally invasive treatment.
