No-touch endoscopic full-thickness resection using reopenable-clip over-the-line method for gastric gastrointestinal stromal tumor

With advancement of endoscopic resection and wound closure techniques, endoscopic resection of gastric gastrointestinal stromal tumors (GISTs) has evolved rapidly in recent years. However, concerns remain regarding the oncologic safety of this procedure, particularly the risk of tumor injury and the adequacy of the resection margins. To solve these problems, the no-touch endoscopic full-thickness resection (EFTR) technique, in which the tumor is removed with a 0.5–1.0-cm resection margin of the muscularis propria, has recently been proposed [1].
