B型超声对先天性肥厚性幽门狭窄手术近期疗效观察的应用价值

The diagnostic value of ultrasond on curative effects in patients with congenital hypertrophic pyloric stenosis after pyloromyotomy

目的探讨B超在小儿肥厚性幽门狭窄(CHPS)中的术前诊断和术后观测幽门恢复的应用价值。方法21例CHPS患儿分别于术前、术后7d、1个月、3个月、6个月进行B超检查,测量幽门管内径、长度和肌壁厚度。结果术前幽门管长度、幽门环肌前壁厚度、后壁厚度均符合CHPS超声诊断标准,术后7d,幽门环肌前后壁厚度增厚(P<0.01);术后3个月,幽门环肌前壁较术前明显变薄(P<0.01);术后6个月,21例患儿幽门管直径、长度、幽门肌后壁恢复正常(P<0.01)。结论超声不仅可做为诊断CHPS的优选方法,而且可观测术后幽门管的恢复过程。

Objective To evaluate the use of ultrasond in diagnosing congenital hypertrophic pyloric stenosis （CHPS）, and in monitoring the course of restoration of pylorus after operation. Methods Repeated uhrasond were performed in 21 children with CHPS at the 7 day, 1 month, 3 months, and 6 months after pyloromyotomy. And the length, diameter and wall - thickness of pylorus were measured. Results The wall - thickness of pylorus was lightly increased after operation at the 7th day （ P 〈 0.0! ）, but during 3 - 6 months the wall - thickness, the length and the diameter of pylorus got to normal after operation （P 〈 0.01 ）. Conclusion Ultrasonography would be useful in diagnosing CHPS, and monitoring the recovery of pylorus after pylormyotomy.
