Snare-tip soft coagulation to treat esophageal stent epithelial hyperplasia.

A 65-year-old man with a spontaneous esophageal perforation (Boerhaave syndrome) was managed with a partially covered metal stent (23 mm wide × 12.5 mm long). After an indwelling time of 8 weeks, endoscopic removal was attempted. Significant epithelial hyperplasia was noted at the proximal and distal ends of the stent ([Fig. 1 a, b]). Despite treatment with argon plasma coagulation (APC) combined with stent-in-stent insertion [1], attempts at removal failed.
