Successful perforation management during esophageal endoscopic submucosal dissection using the stent-anchoring...

Patients with esophageal endoscopic submucosal dissection-associated adverse events can have a severe clinical course. In this report, we describe the case of a 67-year-old male with a history of endoscopic submucosal dissection who had metachronous superficial esophageal cancer. Although endoscopic submucosal dissection was attempted for challenging lesions adjacent to the scar, perforations occurred during the procedure. We placed an esophageal fully covered self-expandable metallic stent at the perforation site to avoid emergency surgery after lesion removal. However, stent migration and displacement concerns remained, as no stenosis was observed in the esophagus. Therefore, a clip with a thread on the upper edge of the stent was placed, and this anchoring clip was useful in preventing stent migration and closing the perforation. The patient improved with conservative treatment. In conclusion, the stent placement and anchoring method with clip and thread could be a treatment option in such cases.
