Aorto-gastric fistula caused by an esophageal stent used in the treament of bariatric surgery's complications

We recently observed an unusual complication related to the use of an esophageal stent. MM, man of 52 years, with history of diabetes type 2, dyslipidemia, arterial hypertension and ischemic heart disease, underwent in 1999 of an adjustable ring gastro- plasty to correct morbid obesity. He also underwent a cholecystectomy and an appendectomy complicated by peritonitis. On May 2013, a gastric bypass was performed to treat recurrence of obesity. This procedure was complicated in June by epigastric pain and vomiting. Gastro-jejunal anastomosis stenosis and gastro-gastric fistula were quickly diagnosed. An endoscopic balloon dilation was performed. In July, regarding recurrence of stenosis and fistula persistence, we decided to implant a Niti-S Beta Taewong type esophageal stent (1).
