What is the ideal indwelling time for metal stents after endoscopic ultrasound-guided gastrojejunostomy? Case report of delayed iatrogenic perforation with a review of the literature

Abstract

Several recent studies have described the feasibility, efficacy and safety of the placement of lumen-apposing metal stents (LAMS) for the treatment of gastrointestinal strictures. However, the optimum stent indwelling time is unclear. We reviewed the literature on endoscopic gastroenterostomy (GE) with a focus on the stent indwelling time and we described the first reported case of iatrogenic perforation six months after Axios stent placement. In the literature review (n = 239), the composite technical success rate and clinical success rate were 93.7% and 87.9%, respectively. The mean follow-up period was 191 days, and the mean stent indwelling time was 88 days. Among 13 studies (n = 202), the mean rate of complications was 13.4%. The principal complication was mis-deployment of the stent (4.5%). We report a case report of delayed iatrogenic perforation. A 59-year-old male patient with cystic dystrophy of the duodenum has been followed for several years. He presented with anorexia following duodenal obstruction and underwent endoscopic ultrasound-guided gastrojejunostomy. Six months later, he was referred to our center due to septic shock, and abdominal computed tomography revealed peritonitis secondary to a perforation of the small intestine, opposite the Axios stent. The mean LAMS indwelling time after GE was 88 days. To minimise the rate of adverse events, such as ulceration and mucosal overgrowth, regular abdominal computed tomography and endoscopy can be performed to evaluate the local effect of the stent. When the disease has resolved, the LAMS must be removed as soon as possible.
