Factors such as operation time, intraoperative perforation, postoperative adverse events, postoperative fasting time, antibiotic use, hospitalization duration, costs, and pathological diagnosis were compared between the two procedures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 180 patients with submucosal tumors were included in this study. The MSR-ESE group consisted of 75 patients (41.7%), while the ESE group had 105 patients (58.3%). Propensity score matching (PSM) showed no significant differences in postoperative antibiotic use, fasting time, or intraoperative perforation between the two groups (<jats:italic>P<\/jats:italic>&amp;gt;0.05). However, the MSR-ESE group demonstrated shorter operation and hospitalization times, lower hospitalization costs, and a reduced incidence of postoperative peritonitis (<jats:italic>P<\/jats:italic>&amp;lt;0.05). Multivariate logistic regression analysis identified operation time as an independent risk factor for unplanned intraoperative perforation, with the likelihood of perforation increasing significantly as operation time increased (<jats:italic>P<\/jats:italic>=0.007, OR=1.015, 95% CI, 1.004 to 1.026).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>MSR-ESE outperforms ESE
