中文摘要 | 背景:直腸腫瘤臨床術前分期對外科醫師在治療診斷上是很重要的。其中內視鏡直腸超音波為一種常用的工具。本研究依據手術標本之病理分期為基準分析ERUS在臨床術前分期的準確度。 方法:共67位直腸腫瘤病患,其術前ERUS分期和術後病理組織做分析比較。 結果:比對手術原有病理報告的腫瘤深達度,ERUS在術前腫瘤深度側量準確度為88%。高估為9%,低做為3%,腫瘤周圍淋巴腺預測其準確度為73%,敏感度77%,專一度70%。 結論:用於直腸腫瘤術前分期ERUS是一種具有客觀,方便,和高準確性的工具。因而可幫助外科醫師判斷適合的治療方式。 |
英文摘要 | Background: Preoperative clinical staging of rectal tumors is very important to allow surgeons make informed decisions about the types of surgeries that should be performed. Endocrectal ultrasonography (ERUS) is one of the tools that has been commonly used in clinical staging of rectal tumors. The aim of this study was to evaluate the accuracy of the reoperative rectal tumor staging using endorectal ultrasonography in comparison with the postoperative histopathological staging. Methods: The histopathology findings of the 67 patients with rectal tumors who underwent preoperative ERUS were reviewd and compared. Results: The overall accuracy of the ERUS assessment in the depth of tumor invasion was 88%, with overstaging at 9% and understaging at 3%. In determining perirectal nodal involvement of the 59 patients that were treated by radical rectal resection, the accuracy was 73%, with sensitivity of 77% and specificity of 70%. Conclusion: ERUS is an objective, convenient, and highly accurate tool for preoperative rectal tumor staging, thus helping surgeons to determine the appropriate treatment modalities. |
