本文舛36例直肠癌病人使用术前腔内超声检查肿瘤病变的深度及肛诊检查估计病变深度与术后病理报告相对照。发现直肠内超声检查直肠癌浸润深度的正确诊断率为88.8％,对早期直肠癌的正确诊断率为80％,肛诊检查的正确诊断率仅为52.8％。直肠内超声对正常直肠壁显示5层结构。直肠癌超声图像为边界不规则的低回声或相对低回声区。直肠内超声的使用为临床医生合理选择手术方式提供了客观依据。
In this paper, 36 cases of rectal cancer patients were compared with the postoperative pathological reports using the depth of preoperative intracavitary ultrasound examination and the depth of the rectal examination. The correct diagnosis rate of rectal cancer infiltration depth was found to be 88.8% in rectal ultrasound, 80% in early rectal cancer, and 52.8% in rectal examination. Rectal ultrasound shows a 5-layer structure on the normal rectal wall. Ultrasound images of rectal cancer are irregular hypoechoic or relatively hypoechoic regions. The use of intrarectal ultrasound provides an objective basis for the clinician to choose a reasonable surgical procedure.
