摘　　要：目的 分析食管病变内镜下黏膜切除术后食管狭窄的可能的危险因素.方法 2008年至2009年间,共对219例食管早期癌或癌前病变进行内镜下黏膜切除术治疗,其中9例出现食管狭窄,对这9例患者（狭窄组）的病变性质、范围、治疗情况等进行回顾性分析,并与其它术后无狭窄患者（对照组,n=202,有8例术后病理证实有黏膜下层浸润,转外科手术,未纳入比较）进行比较.结果 两组患者在性别、年龄、病变位置、病变长度及术后病理方面无显著差别,但狭窄组创面范围＞3/4食管周径的比例（8/9,88.9%）明显高于对照组（9/202,4.5%,P＜0.01）.结论 对内镜治疗后范围超过食管周径3/4的早期食管癌或癌前病变,内镜下黏膜切除术后发生食管狭窄的风险明显增加.Objective To analyze the possible risk factors of esophageal stenosis after endoscopic mucosal resection （EMR）. Methods From January 2008 to December 2009, a total of 219 procedures of esophageal EMR were performed to resect early esophageal squamous carcinoma and its precancerous lesions,and esophageal stenosis was observed in 9 cases. Data of these 9 patients （ stenosis group） were collected and compared with those of patients without stenosis （ control group, n = 202, 8 patients were excluded because of being diagnosed as squamous carcinoma with submucosal infiltration after EMR and being transfered to surgery）. Results There was no significant difference between two groups in regard of gender, age, location of the lesion, length of the lesion or pathological diagnosis after EMR, while the rate of patients with mucosal defect larger than 3/4 circumference in stenosis group （ 8/9, 88.9% ） was significantly higher than that in control group （9/202, 4. 5%, P 〈 0. 01 ）. Conclusion In EMR for early esophageal squamous carcinoma and its precancerous lesions, post-EMR mucosal defect larger than 3/4 circumference is a risk factor for esophageal stenosis.
