Core Tip

Core Tip: Gastric cancer is a common malignant tumor of the digestive system worldwide. Endoscopic submucosal dissection (ESD) is the first-line treatment for early gastric cancer. However, the long operation time of ESD and its postoperative delayed hemorrhage are the major complications, which can cause more severe cardiovascular complications, such as bradycardia and hypotension. In this retrospective analysis study, the risk factors of long operation time and postoperative delayed hemorrhage were studied. Lesion diameter and shape, ulcer or scar, perforation, and invasion depth all affected the operation time, and lesion diameter, lesion shape, and ESD operation time were independent factors for the occurrence of delayed hemorrhage after ESD.
