1956年 Raid 和 Wild 曾设想用腔内超声扫描诊断直肠癌复发。由于技术原因,直至1983年Drag-sted等才首次在临床实践并获得成功。近代结直肠外科的发展,对早期直肠癌和位于括约肌以上的低位直肠癌仅侵及固有肌层者,主张作局部切除或保留括约肌手术。然而,手术方式的选择和估价预后必须基于术前对肿瘤浸润深度与范围的正确判断。迄今常用的直肠指检、钡剂灌肠、内窥镜和 CT 检查等方法,都不足以充分提供肿瘤浸润深度、方向、直肠外扩散程度以及邻近脏器的受累情况,直肠内超声扫描可望解决以上问题。
In 1956, Raid and Wild had envisioned an intraluminal ultrasound scan to diagnose rectal cancer recurrence. For technical reasons, it was not until 1983 that Drag-sted and others were successful in clinical practice for the first time. The development of modern colorectal surgery, for early rectal cancer and low rectal cancer above the sphincter only invade the muscularis propria, advocates for local resection or sphincter preservation surgery. However, the choice of surgical methods and the prognosis of prognosis must be based on the correct judgment of the depth and extent of tumor invasion before surgery. The commonly used methods such as digital rectal examination, barium enema, endoscopy, and CT examination are insufficient to fully provide the depth of tumor invasion, direction, degree of external rectal spread, and involvement of adjacent organs. An intrarectal ultrasound scan is expected to be resolved. The above problem.
