目的：通过直肠癌术前腔内超声分期与术后病理分期比较，评价直肠腔内超声检查对直肠癌术前分期的价值。方法：腔内超声探头插入后，装备7－MHz换能器．缓慢地退出探头，仔细检查肿瘤和直肠周围淋巴结。结果：56例直肠癌术前腔内超声分期与术后病理分期（Astler－coller分期）A、B、C期的符合本分别为100％、89％、82％。结论：腔内超声能分辨直肠壁各层结构，并判断直肠壁浸润的深度和程度，准确率达80％以上，具有方法简便、迅速、天创伤、费用低廉等优点，可作为直肠癌术前分期的常规手段。
OBJECTIVE: To evaluate the value of rectal cancer ultrasound in preoperative staging of rectal cancer by comparing preoperative staging of intracanal ultrasound with postoperative pathological staging. Method: 7-MHz transducer is equipped after intracavity ultrasound probe insertion. Slowly exit the probe and examine the tumor and lymph nodes around the rectum. RESULTS: The consistency of preoperative intraluminal ultrasound staging and postoperative pathological staging (Astler-coller stage) A, B, and C in 56 cases of rectal cancer were 100%, 89%, and 82%, respectively. Conclusion: Intraluminal ultrasound can distinguish the structure of the rectal wall and determine the depth and degree of rectal wall infiltration. The accuracy rate is more than 80%. It has the advantages of simple, rapid, day trauma, low cost, etc. It can be used as preoperative rectal cancer. The conventional means of staging.
