Transparent cap adjusted the stent placed for stenosis after endoscopic injection of esophageal varices: A case report

Figure 1 Transparent cap adjusted the stent placed for stenosis after endoscopic injection of esophageal varices. A: Residual varices were observed above the stricture, and we should be alert to residual varices; B: The esophageal stricture exposed entirely; C: We used balloon dilatation to improve the stricture; D: The self-expanding metal stents (SEMS) was passed through the stricture by a hard wire girding; E: We should be alert to the residual varices, when we were placing the SEMS; F: After the implanting the SEMS, the stricture was improved obviously; G: Oral side of the stent embedded into the esophageal mucosa; H: The recycling line was pulled for shrinking the stent; I: We try to pull the recycling line for shrinking the SEMS to remove mucosa embedded the stent; J: Mucosa embedded the stent could not be removed by shrinking the SEMS; K: A forceps was performed to remove mucosa embedded the stent, nevertheless, the bleeding was obvious; L: A transparent cap was used to scrape the mucosa embedded the stent; M: The tissue was scraped and pushed into the stomach along the SEMS with a transparent cap; N: Mucosa embedded the stent were removed successfully without bleeding.
