ARTICLE HIGHLIGHTS
Research background

Endoscopic submucosal dissection (ESD) has become a new development trend in the treatment of early gastric cancer due to its special minimally invasive advantages. Although it is minimally invasive surgery, it also has some risks such as bleeding and perforation.

Research motivation

The time of ESD operation is closely related to bleeding and perforation.

Research objectives

This study aims to investigate the operation time of endoscopic subspecific section and the influencing factors of delayed bleeding after operation.

Research methods

The baseline data, clinical features, and endoscopic and pathological characteristics of patients were collected. The multivariate linear regression model was used to investigate the influencing factors of ESD operation time. Logistic regression analysis was carried out to evaluate the influencing factors of postoperative delayed hemorrhage.

Research results

The maximum diameter of the lesion, lesion morphology, and ESD operation time were independent influencing factors for delayed hemorrhage after ESD. Patients with lesion ≥ 3.0 cm (OR = 3.785, 95%CI: 1.165-4.277), lesion morphology-concave (OR = 10.985, 95%CI: 2.133-35.381), and ESD operation time ≥ 60 min (OR = 2.958, 95%CI: 1.117-3.526) were prone to delayed hemorrhage after ESD.

Research conclusions

The risk of delayed bleeding after ESD is higher when the maximum diameter of the lesion is ≥ 3.0 cm, the lesion morphology is concave, and the ESD operation time is longer.

Research perspectives

Further research should be made on other factors related to delayed bleeding after ESD operation, such as factors during operation and individual related factors. Strict control of surgical indications and adherence to individualized treatment can help reduce the occurrence of complications.
