ABSTRACT

Objective:

To evaluate the effects of hemoclips on preventing delayed bleeding for early gastric cancer (EGC) after endoscopic submucosal dissection (ESD).

Methods:

Clinical data of 459 patients who underwent ESD for EGC in Beijing Friendship Hospital from June 2013 to August 2020 were collected retrospectively. Patients were divided into group A (hemoclip group, n=162) and group B (non-hemoclip group, n=297) according to whether preventive hemostatic clip treatment was performed after resection. Delayed bleeding within 2 weeks after ESD was observed. Univariate analysis and subgroup analysis were conducted for the delayed bleeding incidence and clinicopathological features.

Results:

Delayed bleeding incidences of group A and group B were 3.1% (5/162) and 8.1% (24/297) with significant difference between the two groups ( χ2=4.418, P=0.036). Subgroup analysis showed that there were significant differences in the delayed bleeding incidence between the two groups when the diameter of the tumor >20 mm [3.5% (2/57) VS 15.3% (13/85), χ2=5.016, P=0.025], the tumor located in the lower part of the stomach [1.0% (1/97) VS 10.4% (20/192), χ2=8.425, P=0.004], and the depth of tumor invasion was M/SM1 [3.2% (5/157) VS 8.1% (23/285), χ2=4.072, P=0.044]. There were no significant differences in the delayed bleeding incidence between group A and group B when the diameter of the tumor ≤20 mm, the tumor located in the upper/medial part of the stomach and the depth of tumor invasion was SM2 ( P>0.05).

Conclusion:

Hemoclips can prevent delayed bleeding after ESD for EGC, which is mainly observed in a tumor of diameter >20 mm, located in the lower part of the stomach and M/SM1 tumor invasion. It has little effect on the prevention when the tumor diameter ≤20 mm and located in the upper/medial part of the stomach.
