摘要

本篇研究主要在評估內視鏡超音波術，在分辨粘膜下腫瘤的來源、性質和蔓延範圍等方面其有效性，並作前瞻性分析。自民國75年10月至77年7月近二年間，共搜集14例經由內視鏡後，懷疑爲上腸胃道粘膜下腫瘤者，而所有14個病例全接受內視鏡超音波檢查，其中有9例作上腸胃道鋇劑攝影，13例作了內視鏡生檢切片。結果正確診斷粘膜下腫瘤的凖確率，分別爲內視鏡超音波85.7%，上腸胃道鋇劑攝影66.7%和內視鏡生檢切片23.1%；所以應用內視鏡超音波術對診斷粘膜下腫瘤具有相當高的凖確性；也由於其高度的解象力，更適合用來描繪說明粘膜下腫瘤的組織學來源、性質與蔓延範圍。

A prospective study was undertaken to evaluate the usefulness of endoscopic ultrasonography (EUS) in differentiating the origin, nature and extension of submucosal tumor. During the period from Oct. 1986 to July 1988, there were fourteen patients suspected to have a submucosal tumor (SMT) in upper gastrointestinal (UGI) panendoscopy. Of the 14 patients, all underwent EUS, 9 had a UGI barium meal study, and 13 received a panendoscopic biopsy. The diagnostic accuracy of the different modalities was 85.7%, 66.7%, 23.1% for EUS, UGI barium meal study and panendoscopic biopsy respectively. This study disclosed that the EUS was much more usefulness in the diagnosis of UGI tract submucosal tumors. Owing to its high resolution, it is suitable in delineating the nature, origin and extension of submucosal tumors.
