上消化道黏膜下小间叶组织瘤超声内镜诊治分析

目的分析上消化道间叶源瘤的超声微探头(MPS)的诊断与内镜下治疗。方法2004年10月～2006年10月共诊治76例上消化道间叶源瘤,所有患者均由MPS和胃镜诊断,47例行MPS指导下内镜切除术,43例进行病理和免疫组织化学染色。结果43例确诊患者中,平滑肌瘤22例,间质瘤17例,分别占51.2%和39.5%,合计占90.7%,均在MPS指导下成功切除,并发症少见。结论绝大多数间叶源性瘤是平滑肌瘤和间质瘤,分别位于黏膜肌层和固有肌层。MPS能准确诊断间叶源瘤,但不能区分平滑肌瘤和间质瘤,间叶瘤内镜下切除效果良好。

Diagnosis and treatment by miniprobe sonography for patients with upper gastrointestinal mesenchymal tissue tumours

Objective To study the diagnosis and treatment of upper gastrointestinal mesenchymal tissue tumours(UGMTT)by miniprobe sonography(MPS).Meshods 76 patients with upper gastrointestinal mesenchymal tissue tumours were examed by MPS,of which 47 patients underwent EUS-assisted therapy,including 43 patients diagnosed as by biopsy.Results Gastrointestinal stromal tumours and leiomyoma account for 39.5% and 51.2% respectively.The resection of tumours by MPS were carried completely and complications such as bleeding were rare.Conclusion MPS may be a good method to diagnose upper gastrointestinal mesenchymal tissue tumours and resections for myogenic tumours by MPS are both safe and effective.
