术前标识对黏膜下隧道内发现食管黏膜下肿瘤的作用研究

目的探讨术前标识对行隧道内镜方法发现食管黏膜下肿瘤的作用。方法将2012年3月-2016年8月于该科室明确诊断病变大小为1.0~2.0 cm的食管黏膜下肿瘤40例随机分为A、B两组,A组采用在距病变3.0 cm处常规行经黏膜下隧道内镜切除术(STER),B组采取先从食管腔内病变处行黏膜下盐水注射,再由下而上成一条直线多点黏膜下注射至距病变3.0 cm处再行STER法,记录两组患者发现瘤体时间。结果 A组平均用时(420.0±25.0)s,B组平均用时(300.0±25.0)s,B组用时更少,两组间差异有统计学意义。结论采取标识法行STER法较传统STER法更具优势。

Method for the detection of submucosal tumors of the esophagus in submucosal tunnel under the preoperative identification

Objective?To investigate the preoperative identification of esophageal submucosal tumor by endoscope.?Methods?40 patients of esophageal submucosal tumors with lesions range from 1.0 to 2.0 cm from March 2012 to August 2016 were randomly divided into A, B groups. Patients in group A underwent submucosal tunneling endoscopic resection (STER) 3.0 cm from the lesions, while patients in group B first underwent submucosal injection of saline to mark the lesions, then perform STER in the same way. Then record the time of checking. ?Results?The average time of group A was (420.0 ± 25.0) s, the average time of B group was (300.0 ± 25.0) s, there was statistical differences between the two groups.?Conclusion?Preoperative identification of the lesions before STER holds more advantages.
