摘要
目的 :探讨B型超声在肥厚性幽门狭窄术前诊断及观测术后幽门恢复过程的应用。材料和方法 :对 3 9名患儿分别于术前、术后 7天、1个月直至 6个月时进行超声检查 ,详细测量幽门管各径值。结果 :术前幽门管长径 2 0 .13±2 .81mm ,直径 13 .97± 1.87mm ,肌层厚度 4.81± 0 .78mm ;术后 7天时 ,切口部位肌层明显变薄 ;术后 2个月 ,前壁肌层厚度恢复正常 ;术后 4个月 ,长径、直径及左右侧壁肌层厚度恢复正常 ;术后 5个月 ,后壁肌层厚度恢复正常。结论 :超声不仅可作为肥厚性幽门狭窄的首选检查方法 ,而且可观测术后幽门管的恢复过程。
Purpose: To evaluate the usefulness of ultrasonography in diagnosing hypertrophic pyloric stenosis(HPS),and in monitoring the course of restoration of pylorus after surgery. Materials and Methods: Repeated ultrasonography over stomach on 39 children suffering from HPS was performed before, at the 7th day, and during 1～6 months after pyloromyotomy. The length, the diameter, and the wall-thickness of pylorus were carefully measured. Results: The length of pylorus was 20.13±2.81mm, the diameter 13.97±1.87mm, and the wall thickness 4.81±0.78mm before operation. The wall thickness was found reduced 7 days after the operation, especially on the anterior wall that returned to within normal range 2 months later. The length, diameter and the muscular thickness of right and left lateral walls normalized at the 4th month after surgery. The thickness of the posterior wall was back to normal at the 5th month. Conclusion: Ultrasonography was feasible in diagnosing HPS, with special value in monitoring the recovery of pylorus after pylormyotomy.
