Hypertrophic pyloric stenosis: a 331 cases report

ABSTRACT

Hypertrophic pyloric stenosis [HPS] is a frequent infant disease. Its diagnosis is very easy, based on its classical clinical features and ultrasonography. The aim of this study is to evaluate the management of HPS in the Paediatric Surgery Department of Casablanca over a period of 25 years [1977-2002]. We recorded 331 cases and we compared the management of this pathology before and after 1992. The mean age of diagnosis was 52 day-old before 1992 and 34 day-old after 1992. The diagnosis was based on oesophago-gastric barium swallow before 1992, and only on abdominal ultrasonography after. The surgical incision is umbilical since 1992. Death rates decreased from 8% to 2%, showing improvement of the management of HPS since 1992. This improvement can be achieved through an earlier diagnosis and an adequate medical care before surgery
