Comparison of Pre-Operative Clinical Condition and Values Ultrasound Findings with Postoperative Outcome of Surgical Treatment of Infants with Congenital Hypertrophic Pilorostenosis (CHP)
Congenital hypertrophic pilorostenosis is a relatively common illness with an incidence of 2-3.5 on 1000 live-born children. (1,2) Most commonly affects prematuruses, firstborn and male children (male to female ration is 4:1 ) in the period of the 3rd to 6th week of life.
