Аннотация:Since being developed and established in Japan, endoscopic submucosal dissection (ESD) has been widely used as a standard treatment for early gastric cancer [1]. Delayed perforation is an occasional complication of ESD, and despite its low incidence, it is a serious complication frequently requiring emergency operation [2] [3] [4]. Polyglycolic acid (PGA) sheets (Neoveil; Gunze Co., Japan), composed of bioabsorbable material, can be used to strengthen the ulcer floor after ESD [5]. We report the successful use of PGA sheets as a conservative treatment for delayed perforation.
