TY - JOUR ID - TI - The Role of Ultrasonography in Infantile Hypertrophied Pyloric Stenosis AU - Mohammed S. Al-Alawee PY - 2006 VL - 5 IS - 1 SP - 1 EP - 7 JO - Iraqi Postgraduate Medical Journal المجلة العراقية للاختصاصات الطبية SN - 83601608 98932708 AB - ABSTRACT:BACKGROUND:To evaluate the different parameters used in the diagnosis of infantile hypertrophied pyloric stenosis (pyloric canal length, muscle thickness and pyloric canal diameter).METHODS:The study group consisted of 29 patients presented with projectile vomiting, 28 patients were diagnosed as pyloric stenosis and only one patient with pylorospasm using linear probe 7.5-10 MHz.RESULTS:The male infants were 23 (82%) and, the female infants were 5 (18%) with male to female ratio of 4.5:1. The age ranged between 18 days and 90 days with a mean of 34.2 days. The age at presentation mostly was between 20-39 days (67.8%). Family history was positive in 5 patients (17.8%). In 16 patients (57.1%) the parents were relative while in 12 (42.8%) patients the parents were not relative. The length of the canal ranged from 15mm to 26mm with a mean of 19.13mm. The muscle thickness ranged from 3-8 mm with a mean of 5.8mm. The diameter of the canal ranged from 11mm to 17mm with a mean of 13.8mm. Only one patient (3.6%) had associated congenital abnormality which was ectopic kidney. And only one patient had pylorospasm.CONCLUSION:The length of the pyloric canal was the most reliable measurement in the diagnosis of infantile hypertrophied pyloric stenosis.
