A 72-year-old female underwent gastric bypass with concomitant cholecystectomy by laparoscopy in 2004 for morbid obesity. Fifteen years later, the patient developed progressive dysphagia for solid food and lost 20 kg in the past 8 months with general asthenia and protein–calorie malnutrition. After multiple examinations (computed tomography scan, esophagogastroduodenoscopy, and positron emission tomography–computed tomography), the patient was found to have stage IV gastric adenocarcinoma (isolated cells, HER-2 negative, and microsatellite stable) of the pyloric and prepyloric region of the gastric remnant with peritoneal carcinosis. The tumor was extrinsically compressing the jejunum (alimentary limb) right after the gastrojejunal anastomosis causing an obstruction. After multidisciplinary tumor board discussion, the expected survival was estimated to be around 6 months and palliative chemotherapy with fluorouracil, leucovorin, oxaliplatin, and docetaxel was initiated. As the patient was still symptomatic and a new dilatation of the bile ducts was noted (alkaline phosphatase: 170 U/L, gamma-glutamyl transpeptidase: 160 U/L, and transaminases and bilirubin: normal), it was decided to realize an EUS-directed gastrogastric anastomosis using a metallic Hot AXIOS™ stent [20 mm × 10 mm, Boston Scientific, [Figure 1]a and [Figure 1]b. This strategy was adopted to be able to reach the remnant gastric cancer in order to put a gastroduodenal uncovered stent (TaeWoong Medical, 22 mm of diameter and 12 cm of length) and dilate the tumoral stenosis [Video 1 and [Figure 2]a, [Figure 2]b, [Figure 2]c, to recreate the physiological digestive path to improve her caloric intake, and to have potential access to the biliary tree if needed. A jejunal self-expandable metallic stent in the alimentary limb was not considered due to the risk of stent migration and impaction. Moreover, surgical and percutaneous procedures were not considered because of the presence of peritoneal carcinosis and ascites in important quantity. She was able to leave the hospital 3 weeks after the last endoscopic procedure. The patient unfortunately died a couple of weeks later due to rapid disease progression.

Roux-en-Y gastric bypass precludes direct endoscopic evaluations of the excluded stomach, which renders detection of a tumor of the gastric remnant challenging., EUS-directed gastrogastric anastomosis using a metallic stent after Roux-en-Y gastric bypass enables to regain access to the remnant excluded stomach and to reach the pancreatobiliary limb., This recently described EUS technique should be considered a promising technique in patients with gastric bypass presenting with choledocolithiasis or cancer of the gastric remnant.
