Olympus reviewed a literature titled "the value of endoscopic ultrasonography in the endoscopic resection of gastrointestinal stromal tumors".This retrospective, single-center study was aimed to explore the clinical value of endoscopic ultrasonography (eus) in the endoscopic resection of gastrointestinal stromal tumors (gists).A total of 92 patients were included were underwent endoscopic treatment, of which 89 (96.7%) patients underwent complete pathological resection.Of these 92 patients, 37 (40.2%) underwent endoscopic submucosal dissection (esd), 27 (29.4%) underwent endoscopic submucosal excavation (ese), 15 (16.3%) underwent endoscopic full-thickness resection (eftr), nine (9.8%) underwent endoscopic band ligation (ebl), and four (4.3%) underwent submucosal tunneling endoscopic resection (ster).The study reported a 78.7% rate for preoperative diagnosis rate of eus and postoperative pathological diagnosis of gists.The presence of a non-homogeneous echo and liquid anechoic zone in gists often indicated higher risk (p < 0.05).The study concluded that endoscopic resection of gists is feasible and safe.Eus is of great significance for the diagnosis and risk assessment of gists and can assist in the endoscopic resection of gists.Complications: intraoperative bleeding occurred in two patients (2.2%), and both of these cases occurred during ese.Thermal biopsy forceps and titanium clamps were successfully used to stop the bleeding.Perforation occurred in 13 patients (14.1%; cases of perforation during eftr were not included), three of which occurred during ebl, six during esd, and four during ese.These perforations were successfully closed with titanium clips, titanium clips combined with a purse-string suture, or otscs®.After the procedure, electrocoagulation syndrome occurred in seven patients (two cases after esd, two after ese, and three after eftr).All the patients improved after conservative treatments, such as the deprivation of food and water, rehydration, or rational intravenous use of antibiotics.Postoperative perforation occurred in one patient undergoing esd, and the patient improved after surgery.The authors used 4 olympus devices: dual-knife (kd-655l or kd-655q), it-knife (kd-612l), and and hyaline cap (d-201-11804); and reported the following adverse events: adverse events (number of patients): intraoperative bleeding - (2).Intraoperative perforation - (13).Postoperative perforation - (1).Postoperative coagulation syndrome - (7).This article includes 3 reports: (b)(6): kd-612l (b)(6): kd-655l or kd-655q (b)(6): d-201-11804 this report is 1 of 3 for (b)(6) kd-612l.
