Endoscopic ultrasound-guided gastrojejunostomy as a rescue therapy for gastric outlet obstruction in a patient with multiple previous procedures
Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a new minimally invasive alternative for palliation of malignant gastric outlet obstruction (GOO)  . However, data are lacking about its feasibility and safety in patients with previous EUS-guided biliary procedures or surgical jejunostomy.
A 57-year-old woman presenting with a locally advanced pancreatic cancer was referred to our department because of GOO. An uncovered duodenal stent of 12 cm was placed. Subsequently, the patient developed acute cholangitis and an EUS-guided hepaticogastrostomy was performed using a partially covered 10-cm self-expanding metal stent (SEMS; Hanarostent; MI-Tech, Gyeonggi-do, Rep. of Korea) combined with an antegrade fully covered stent ([Fig. 1]). Both treatments were effective; however, 6 months later, she developed a new episode of GOO due to occlusion of the duodenal stent. A surgical jejunostomy was carried out, but the improvement was moderate, and the patient expressed her desire to eat by mouth. Meanwhile, she underwent two exploratory laparoscopies without evidence of carcinosis.
It was decided to perform an EUS-GE despite the suspicion of fixed proximal jejunal loops and the long duodenal stent covering almost all of the angle of Treitz. First, a 7-Fr canula was passed through the duodenal stent using a colonoscope. Two contrast injections and careful water instillation were performed through the catheter and the surgical jejunostomy ([Fig. 2]). Second, the echoendoscope was positioned facing the angle of Treitz and the optimal proximal jejunal loop segment was chosen, paying attention to the position of the distal end of the duodenal stent. The hepaticogastrostomy was placed far away in the proximal stomach. A hybrid technique using a 20-mm lumen-apposing metal stent (LAMS; Hot AXIOS; Boston Scientific, Voisins-le-Bretonneux, France) with a preloaded 0.0035-inch guidewire (Jagwire; Boston Scientific) was performed without complications ([Video 1]).

The patient was able to tolerate an oral solid intake 24 hours later. She underwent an abdominal computed tomography (CT) scan 1 week later, which confirmed the permeability of the gastrojejunostomy, with no oral contrast passing through the hepaticogastrostomy ([Fig. 3]).
