Abstract:
Objective:To evaluate the efficacy and safety of non-submucosal injection in endoscopic submucosal excavation (ESE) for small submucosal tumors originating in the muscularis propria of the stomach.Methods:A total of 138 patients diagnosed as having small gastric muscularis propria tumors (≤2 cm) at Digestive Endoscopy Center of Zhejiang Provincial Hospital of Chinese Medical from November 2018 to October 2020 were randomly divided into the observation group with non-submucosal injection of ESE and the control group with submucosal injection of ESE for a randomized controlled trial. The exposure time, tumor removal time, operation cost, hospitalization period, numbers of metal clips and complications of the two groups were analyzed and compared.Results:A total of 138 patients were enrolled, including 76 patients in the observation group and 62 patients in the control group. All lesions were successfully and completely removed. Compared with the control group, the observation group had shorter median tumor exposure time [2.00 min VS 3.30 min, Z=-2.426, P =0.045], shorter median tumor removal time [16.8 min VS 34.4 min, Z=-4.324, P<0.001], less median surgical cost [2 903 yuan VS 3 178 yuan, Z=-5.112, P<0.001], and fewer metal clips used (4.0±0.6 VS 5.1±1.3, t=1.452, P=0.003). The incidence of postoperative abdominal distension of the observation group was lower [9.2% (7/76) VS 22.6% (14/62), χ2=2.512, P=0.049], the incidence of postoperative abdominal pain of this group was lower too [11.8% (9/76) VS 32.3% (20/62), χ2=4.242, P=0.014], but there was no significant difference in the period of hospitalization, incidence of postoperative fever or perforation ( P>0.05). Conclusion:Non-submucosal injection of ESE is safe and effective for submucosal tumors smaller than 2.0 cm originating from the muscularis propria of the stomach , which might be more advantageous than traditional ESE.
