Ultrasound of Hypertrophic Pylorian Stenosis: About A Case and Literature Review

Abstract

Hypertrophic pyloric stenosis is an obstruction of the lumen of the pylorus by muscular hypertrophy of the pyloric sphincter, more common in boys. We report the case of a male newborn at 13 weeks of life, born at term with a birth weight estimated at 2900 grams without any particular history. Clinically he had an increased frequency of sputum and postprandial jet vomiting, dehydration and weight loss. Abdominal ultrasound found a lengthening of the pyloric canal measuring 22 mm in length associated with a thickening of the muscularis of the pyloric region measuring 4 mm forming a "pyloric olive" 13 mm in diameter. There was also significant gastric stasis upstream of the hypertrophic stenosis. The examination was carried out at the reference health center of commune III in the district of Bamako. The objective of this work was to provide our experience on the ultrasound semiology of hypertrophic pyloric stenosis with a review of the literature.
