摘要
目的探讨内镜黏膜下剥离术（endoscopic submueosal dissection，ESD）治疗直肠类癌的临床疗效及安全性。方法选择7例结肠镜发现的距肛门8cm以内直肠肿物行ESD治疗。内镜下先于病变边缘做标记点，沿标记点环形切开黏膜，于病灶下方剥离黏膜下层，同时多次黏膜下注射，保持病灶与肌层分离，直至完整剥离肿瘤。结果7例术后病理诊断为直肠类癌，肿瘤直径0．9～1．6em，均成功经内镜切除，基底及距切缘0．2cm以内无类癌组织累及。随访13～28个月，未见肿瘤残留和复发。结论ESD用于治疗直径≤2．0cm、未侵犯固有肌层的直肠类癌，具有较好的安全性。
Objective To evaluate the clinical efficacy and safety of endoscopic submueosal dissection （ESD） in treatment of rectal eareinoid tumors. Methods ESD was performed in 7 patients with rectal tumor less than 8 cm from the anal found by colouoscopy. We made marks around the lesions from the margin under the colonoscopy, and eut the mucosa and sub-mucosa along the marks, then injected solution into submucosa to elevate the lesion until the lesion was completely removed. Results 7 patients were diagnosed as having carcinoid tumor by pathological analysis. Ranging from 0.9 to 1.6 cm, all rectal carcinoid tumors were completely resected with substrate and basal resection margins free of tumor tissue （≤0.2 cm）. All patients were followed up for 13 to 28 months with no residue or recurrence. Conclusion ESD in treatment of rectal carcinoids tumors with diameter≤2.0 cm and no infringing muscularis propria is sate and effective.
