Abstract
Objective To analyze the clinical effect of endoscopic submucosal dissection (ESD) on gastric mucosal lesions and the main risk factors of delayed hemorrhage after surgery. Methods Seventy-eight patients with gastric mucosal lesions were enrolled in the study. All patients underwent ESD, and the complete clinical data were retrospectively analyzed. The clinical curative effect and risk factors of delayed hemorrhage after surgery were summarized. Results After one year of ESD, the survival rate of patients was 100%, the residual or recurrence rate was 2.56%. There were 8 cases of delayed hemorrhage after surgery, accounting for 10.26%. The age, time of antithrombotic drugs withdrawal before surgery, times of biopsy, with ulcer or scar, lesion size and surgical time showed significant differences between patients with and without delayed hemorrhage (P<0.05). Conclusions The implementation of ESD in patients with gastric mucosal lesions can obtain good curative effect. The survival rate of patients is high, and the residual or recurrence rate is low. The related risk factors of delayed hemorrhage after surgery include age, time of antithrombotic drugs withdrawal before surgery<7 d, times of biopsy more than twice, long surgical time, with ulcer or scar and lesions ≥ 5 cm.
