Using oral ultrasonic bowel contrast solution to diagnosing colorectal tumor

目的：探讨口服肠道超声显影液在结、直肠占位性病变中的应用价值。材料和方法：患者空腹排便后服肠道显影液７０～８０ｍｌ，饮水５００～７００ｍｌ，待结、直肠充盈后，经腹部进行超声检查。结果：共检出息肉样病变５４例，恶性肿瘤８６例，均经肠镜、手术病理证实。息肉表现为圆形略强回声，附着处肠壁连续关系正常。结、直肠癌表现多样，可分为三型：隆起型、溃疡型和壁厚狭窄型。内部回声有随着瘤体增大，浸润深度增加而逐渐减弱的趋势。超声还可对肿瘤的分期做出判断。另外，还对影响超声检出率及准确性的因素进行了分析。结论：口服超声肠道显影液具有方便、实用等特点，适用于各级医院。

Objective:study the evaluation of oral ultrasonic bowel contrast solution(OUBCS) in colorectal occupancy lesions.Materials and Methods:Taking 70～80ml OUBCS and drinking 500～700ml water after discharging when colorectal filled the transabdminal ultrasound was done.Results:54 cases polyps and 87 cases cancer were detected and they were confirmed by fibercolonoscopy,operation and pathology.Polyps were showed as high echo and the wall was continous.Ultrasonic feature of colorectal cancer were varied.They were three types:prominence,ulceration and thick wall stenosis.The eaho was lower and lower with the mass growing and depthing of invasion.Ultrasound could judge the cancer depth invasion and degree.It was analysed for factors to affect detection and accuration.Conclusion:Oral ultrasonic bowel contrast solution is convineous and effective.It can be adaped for varied hospital.
