FOR RESECTABLE RECTAL gastrointestinal stromal tumors (GIST), transabdominal surgery is typical. In already-vulnerable patients, however, transabdominal surgery has greater associated risks. Transanal surgery, conversely, is a minimally invasive procedure; however, visualization of the operative field can be impaired by lesions adjacent to the anal verge. Feasibility of peranal endoscopic myectomy and endoscopic excavation techniques are comparable to that of advanced endoscopic

对于可切除的直肠胃肠道间质瘤 (GIST)，经腹手术是典型的。然而，在已经脆弱的患者中，经腹手术具有更大的相关风险。相反，经肛门手术是一种微创手术；然而，肛门边缘附近的病变可能会影响手术野的可视化。经肛内镜下子宫肌瘤切除术和内镜开挖技术的可行性可与先进内镜技术相媲美
