目的评估微气水灌肠超声在大肠息肉诊断中的应用价值。方法经置于肛肠内的双腔气囊管注入振荡后产生肉眼能观察到的微气泡的生理盐水1000～1500ml后,运用超声逆向结肠施行扫描检查。结果对136例患者采用微气水灌肠超声检查,检出结肠包块108例,检出病灶206个,其中结肠癌76例(70%),病灶139个(67%),溃疡6例(5%),病灶19个(9%),息肉26例(24%),病灶48个(23%),大肠息肉检出率<1.5cm检出率63%、1.6cm～2.5cm96%,3cm以上100%,检出最小息肉0.8cm×0.9cm,最大息肉4.4cm×4.3cm。全部病例均经纤维结肠镜活检病理诊断或手术证实。结论本方法简便、安全、无禁忌症,检出率高,值得应用。
Objective To evaluate the value of micro-air-water enema in the diagnosis of colorectal polyps. Methods After the double-chamber balloon catheter placed in anus and intestine was injected with 1000 ~ 1500ml of micro-bubble physiological saline which can be observed by the naked eye, the patients were scanned by ultrasound reverse colon. Results A total of 108 colon masses were detected in 108 cases of colon masses, including 206 colon cancer (70%), 139 lesions (67%) and 6 ulcers (9%), 26 cases (24%) of polyps, 48 cases (23%) of polyps, the detection rate of colorectal polyps <1.5cm was 63%, 1.6cm ~ 2.5cm 96% 100%, detected the smallest polyps 0.8cm × 0.9cm, the largest polyp 4.4cm × 4.3cm. All cases were confirmed by pathological diagnosis of colon biopsy or surgery. Conclusion This method is simple, safe, no contraindications, high detection rate, it is worth applying.
