目的探讨腔内超声对直肠癌大体分型的诊断价值。方法 80例直肠癌患者术前行直肠腔内超声检查,观察肿瘤大体形态,根据形态将直肠癌分为隆起型、溃疡型、浸润型3个大体类型。超声分型分别与术后病理分型对照。结果腔内超声诊断直肠癌大体分型的总准确率为68.7%(55/80),其中隆起型准确率为73.8%(31/42),溃疡型准确率为64.0%(16/25),浸润型准确率为61.5%(8/13)。结论腔内超声能较准确地评估直肠癌的大体类型。
Objective To investigate the diagnostic value of endoscopic ultrasonography for gross classification of rectal cancer. Methods 80 patients with rectal cancer underwent intrarectal ultrasound examination before operation. The general morphology of the tumor was observed. According to the morphology, rectal cancer was divided into three general types: bulge, ulcer and infiltrate. Ultrasonic typing and postoperative pathological type control. Results The total accuracy of intracavitary sonography in the diagnosis of rectal cancer was 68.7% (55/80), of which the accuracy of protuberance was 73.8% (31/42) and the accuracy of ulceration was 64.0% (16/25) Infiltration type accuracy rate of 61.5% (8/13). Conclusion The intracavitary ultrasound can accurately assess the general type of rectal cancer.
