Abstract:
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.
