Research progress in preventing delayed bleeding after gastric endoscopic submucosal dissection / 中国综合临床

ABSTRACT

Endoscopic submucosal dissection (ESD) is the common method for treatment of early gastric cancer. Compared with endoscopic mucosal resection (EMR), ESD can completely remove large lesions while ensuring negative margins as much as possible, which enables a more accurate pathological staging of tissue and reduces the risk of postoperative cancer recurrence. On the other hand, ESD generally results in larger ulcerations than EMR, which increases the likelihood of complications such as bleeding and perforation. Delayed bleeding is one of the main complications after gastric ESD. Delayed bleeding after ESD can cause hemorrhagic shock and even death, so we should take effective management strategies to prevent the occurrence of delayed bleeding after gastric ESD, such as the use of acid suppressive drugs, enough intraoperative hemostasis, lesion closure, and the use of lesion covering materials.
