Retrospective and prospective study of infantile pyloric stenosis in Sohag University Hospital

Abstract

Infantile pyloric stenosis is a common entity. It affects about 3 cases in every 1000 live bi1ihs. For many years, the diagnosis of infantile pyloric stenosis was accomplished by palpation of the hypertrophied pylorus. The evolution of modern diagnostic imaging modalities such as ultrasonography and gastrographin meal have limited the role of clinical diagnosis. There is general agreement between pediatricians that surgery is the corner stone of management.

Jn this study, 27 children with infantile pyloric stenosis who were managed in Sohag University Hospital over a 4- years period have been studied both prospectively an retrospectively. The disease was found to be more common in males than in females with a ratio of3.5: I. The probabilty of the disease increases in earlier babies ofthe family and decreases in later babies and the first born babies have the highest chance to be affected.

The mean age at initial symptoms was 21.3 days and at time of presentation to the hospital was 37 days. Vomiting was the presenting symptom in all cases followed by constipation commencing within a mean time of 2.8 days. Visible epigastric peristalsis could be noted in about 59.3 %and the pyloric mass could be palpated in more than 50 % of cases. The mean weight at admission was 3.7 kgms.

Abdominal ultrasonography is increasingly being used to diagnose the disease and gastrographin meal is progresively being restricted to doubtful cases.
