Hypertrophic pyloric stenosis

Case contributed by Dr Fazel Rahman Faizi


Projectile non-bilious vomiting for two weeks

Patient Data

Age: 35 days
Gender: Male

Abnormal thickening and elongation of the pyloric canal are noted giving the cervix sign.

Pyloric canal length measures 21mm.

Pyloric canal transverse diameter measures = 13mm. 

Pyloric single wall thickness measures = 6mm.,

Case Discussion

Pyloric muscle thickness is directly related to the age and weight of the infants, whereas lenght of the pyloric canal is found to have no such a relationship with the age and weight of the infant. 

Younger infants with low weights with the clinical diagnosis of hypertrophic pyloric stenosis may still have hypertrophic pyloric stenosis even if the ultrasonographic minimum diagnostic criterion for hypertrophic pyloric stenosis is not met.
