小探头超声辅助下经双通道内镜食管黏膜下肿瘤剥除术的临床应用

目的探讨小探头超声辅助下经双通道内镜食管黏膜下肿瘤剥除术的临床应用价值。方法1999年1月至2005年5月，选择内镜超声检查诊断为食管黏膜下肿瘤的84例在小探头超声辅助下经双通道内镜行食管黏膜下肿瘤剥除术，术后常规病理组织送检。结果84例患者均成功行内镜下剥除，术后无食管穿孔、食管狭窄等严重并发症，创面渗血2例（2．3％）。83例获得病理诊断，确诊食管间质瘤65例，脂肪瘤17例，神经纤维瘤1例。术后经平均4．1个月的内镜随访，未见病变再发。结论小探头超声辅助下双通道内镜食管黏膜下肿瘤剥除术是一种安全、有效、简便的治疗方法。

Experience in miniprobe sonography-assisted double-channel endoscopic enucleation of submucosal esophageal tumor

Objective To evaluate the clinic application of transendoscopic miniprobe sonography (TEMPS)-assisted double-channel endoscopic intraluminal enucleation(DCEILE)of submucosal esophageal tumor(SMET).Methods Two hundred and eighty three cases of SMET diagnosed by endoscopic ultra- sonography were studied between Jan 1999 and May 2005.TEMPS-assisted DCEILE were performed on 84 selected patients.Histopathological study was executed postoperatively.Results In all patients TEMPS-as- sisted DCEILE procedures were conducted successfully without any serious complications such as perforation, massive bleeding and stenosis.Blood oozing occurred in 2 patients(2.3%).Of the 83 examined cases,65 stromal tumors,17 lipomas and 1 fibroneuroma were confirmed histopathologically.After a follow-up of about 4.1 months,no recurrence was found.Conclusion TEMPS-assisted DCEILE of SMET has been proven to be a safe,effective,convenient and feasible procedure.
