Abstract

Background/Aims : Infantile hypertrophic pyloric stenosis (IHPS) is a common cause of gastric outlet obstruction in infants, and presents as one of the most common surgical conditions of infancy. Although there were many published studies about IHPS worldwide; there was very few published study in our local literature. So we conduct this study to investigate IHPS in form of, presentation, management and overall outcome. Methodology : In this prospective cross - sectional, hospital based study; 42 patients with IHPS, were admitted in Khartoum Teaching hospital department of Pediatric Surgery in the period between Aug. 2011 and May. 2013. Patients were referred from all parts of Sudan. Study variables included were age, gender, and residence, presenting symptoms, clinical sign and postoperative outcomes. Data was collected using a structured, pretested questionnaire and analyzed using a computer program-Statistical Package for Social Sciences (SPSS) version 20. Results were presented in tables and graphs. Results : Forty two patients with IHPS were studied, 78.6% of them were males, 61.9% of the patients were of 3-6 week age group and 50% of them were a first born child. All patients presented projectile vomiting with severe dehydration observed in 88.1% of them. While 90.5% had palpable epigastric olive like mass 69.0% of them had visible peristaltic wave. Abdominal U/S was done for all patients, and confirmed the diagnosis in 97.6% of them. For all patients; open surgical Ramsted#x2019;s pyloromyotomy was done successfully, with 4.8% complications and 2.4% mortality. We observed that dehydration and abnormal laboratory values are the most common findings in IHPS. Surgical operation associated with good outcome.Ultrasound has emerged as the modality of choice for diagnosing IHPS as it is easily, available and sensitive.
