目的 评价直肠腔内超声在诊断直肠周围病变中的应用价值。方法 回顾分析 2 0 6例直肠周围病变声像图表现并与手术病理或临床最终诊断对照。结果 检出直肠周围间隙疾病 83例 ,诊断符合率 95 % ( 79/83 ) ;直肠周围脏器疾病 12 3例 ,诊断符合率 94%。结论 ⑴直肠腔内超声对直肠周围组织间隙、脏器病变的诊断 ;动态时实探查膀胱出口梗阻病因等方面具有重要诊断价值。⑵直肠周围淋巴结L/S比值 (淋巴结长径 /横径 )可作为判断淋巴结良、恶性的重要标志。
Objective To evaluate the value of intrarectal ultrasound in the diagnosis of rectal lesions. Methods A retrospective analysis of 206 cases of perirectal lesions around the sonogram and surgical pathology or clinical diagnosis of the final control. Results 83 cases of rectum interstitial disease were detected, the diagnostic coincidence rate was 95% (79/83). The organ around the rectum was found in 12 3 cases, the diagnostic coincidence rate was 94%. Conclusions ⑴ The diagnosis of rectal ultrasonography on the tissue around the rectum, the pathological changes of the organ; dynamic real time investigation of the cause of bladder outlet obstruction has important diagnostic value. ⑵ lymph nodes around the rectal L / S ratio (lymph node diameter / diameter) can be used as an important marker to determine the benign and malignant lymph nodes.
