Risk of biodegradable stent-induced hypergranulation causing re-stenosis of a gastric conduit after esophageal resection.

Biodegradable stents are increasingly used to treat benign gastrointestinal strictures [1] [2]. Here, we report on two patients who developed persistent vomiting after thoraco-abdominal esophageal resection for cancer and perforation. Assessments by endoscopy and imaging studies demonstrated a severe stricture of the distal gastric conduit in both patients ([Fig. 1]), which were thought likely to be due to low-flow ischemia of the gastric conduit.
