Eco-sonographic examination with 10.0 MHz linear transducer is appreciated gastric cavity containing liquid lumpy, thickened pylorus. wall is 1.72 cm diameter, to be abnormal when greater than 13 mm, with passage of material in reverse (peristalsis) carrying the duodenal contents into the antrum. It is the diagnosis of hypertrophic pyloric stenosis is preparing for corrective surgery. The pylorus shows called "cervix sign" for its similarity to the eco-sonographic appearance of the cervix of women.
Hypertrophic pyloric stenosis typically affects young infants and newborns. It occurs between 2 and 8 weeks of age, peaking between 3 to 5 weeks. Is 4 to 5 times more common among males than females, with an increased incidence in firstborn.
Eco-sonographic diameters are called the pylorus
Keller's findings: muscle thickness 4 mm x 16 mm channel length x diameter 14 mm and Lamki et al: 3 mm thick muscle to less than 30 days, tissue thickness of 6 mm and even greater for older children and longer babies (3), 4 mm x 19 mm x 10 mm (16), muscular wall of pyloric length 5.3 mm x 22.5 mm (17), 5.5 mm x 14 mm x 10 mm (14), diameter 15 mm (15), Devine (18), 4 mm x 17 mm x 10 m.
The patient underwent surgery confirming the diagnosis and shows a full recovery from their intake, disappearing vomiting and completely normal bowel movements .
