Effect of polyglycolic acid sheet plus esophageal stent placement in preventing esophageal stricture after endoscopic submucosal dissection in patients with early-stage esophageal cancer: A randomized, controlled trial

Figure 6 The management of one of the study patients. A: Stent covered with polyglycolic acid (PGA) sheet was injected with glucocorticoid before insertion; B: The mucosal defect after endoscopic submucosal dissection (ESD); C: The combination of PGA, stent, and glucocorticoid was applied after 1 wk; D: The endoscopic appearance of the esophagus 4 wk after ESD; E: The endoscopic appearance of the esophagus 3 mo after ESD.
