摘　　要：BACKGROUND Gastric mesenchymal tumors(GMT)are identified as soft tissue neoplasms that arise from mesenchymal stem cells within the gastrointestinal tract.GMT pri-marily encompass gastric stromal tumors(GST),gastric leiomyomas,and gastric schwannomas.Although most GMT are benign,there are still potential malignant changes,especially GST.Thus,early surgical intervention is the primary treat-ment for GMT.We have designed a simple endoscopic“calabash”ligation and resection(ECLR)procedure to treat GMT.Its efficacy and safety need to be com-pared with those of traditional endoscopic techniques,such as endoscopic sub-mucosal excavation(ESE).AIM To assess the safety and effectiveness of ECLR in managing small GMT(sGMT)with a maximum diameter≤20 mm by comparing to ESE.METHODS This retrospective analysis involved patients who were hospitalized in our institution between November 2021 and March 2023,underwent endoscopic resection,and received a pathological diagnosis of GMT.Cases with a tumor diameter≤20 mm were chosen and categorized into two cohorts:Study and control groups.The study group was composed of patients treated with ECLR,whereas the control group was composed of those treated with ESE.Data on general clinical characteristics(gender,age,tumor diameter,tumor growth direction,tumor pathological type,and risk grade),surgery-related information(complete tumor resection rate,operation duration,hospitalization duration,hospitalization cost,and surgical complications),and postoperative follow-up were collected for both groups.The aforementioned data were subsequently analyzed and compared.RESULTS Five hundred and eighty-nine individuals were included,with 297 cases in the control group and 292 in the study group.After propensity score matching,the final analysis incorporated 260 subjects in each cohort.The findings indicated that the study group exhibited shorter operation duration and lowered medical expenses relative to the control group.Furthermore,the study group reported less postoperative abdominal pain
