Diffuse hypertrophic enlargement of the muscular wall of the pylorus measuring 23 mm in length. It measured 15 mm in width. It measured 7 mm in maximum pyloric muscle thickness during crying.
During crying, the length mildly decreased but the width and muscle thickness mildly increases (thickness increased from 6 mm to 7 mm). This may be due to contraction of pylorus during crying).
Case Discussion
Congenital hypertrophic pyloric stenosis is considered a type of gastric outlet obstruction. It is common in males. It is usually diagnosed if the length is more than 15 mm, width more than 7 mm and muscle thickness more than 3 mm (with variance between studies).
