A 71-year-old man with multiple medical problems presented with gastric outlet obstruction due to pyloric stricture from a nonhealing peptic ulcer and a 10-kg weight loss in 3 months. Biopsies of the stricture and abdominal computed tomography scan were negative for malignancy and infectious causes. He underwent series of endoscopic balloon dilation up to 12 mm without adequate response. He could not tolerate a soft or regular diet and refused to undergo surgery. Thus, EUS-guided gastrojejunostomy (EUS-GJ) was undertaken.
A 30 mm custom-made single balloon catheter (7-French) with below injection was inserted into the proximal jejunum under fluoroscopic guidance [Figure 1]. A water solution containing 0.5% methylene blue and contrast media was infused until the distal duodenum, and proximal jejunum was fully distended [Figure 2]. A 10 mm × 20 mm cautery-enhanced HOT AXIOSTM stent was used to puncture the inflated small bowel loop with a free-hand technique. However, we lost the target bowel loop's visualization during the proximal flange deployment and decided to retrieve the stent [Video 1 [Additional file 1]]. Then, the puncture was reattempted using wire guided, and the stent was deployed. After complete stent deployment, peritoneal fat was visualized [Figure 3] and [Video 2 [Additional file 2]], suggesting perforation. Thus, the stent was removed using rat tooth forceps, and the puncture site was closed with through-the-scope clips. The patient was NPO, and intravenous fluid and antibiotics were given. He did well after 48 h of observation and was discharged. The EUS-GJ was repeated 6 weeks later, and the procedure was successful without complications [Figure 4] and [Video 3 [Additional file 3]].

EUS-GE has emerged as a promising alternative treatment for gastric outlet obstruction. The recent meta-analysis showed that EUS-GE had a 92%–94% technical success and a 90%–91% clinical success.,, Stent misdeployment is not an unusual pitfall occurring in 9.5% of reported cases. The mobility of the small bowel may result in loss of visualization and subsequent stent misdeployment. Insertion of the guidewire can push the small bowel away, thus increasing the risk of stent misdeployment. Potential causes of pitfalls during stent deployment and rescue maneuvers are proposed in [Table 1].
