Abstract
l-lypertrophic pyloric stenosis is the most common surgical disorder producing emesis in infancy with an incidence of approximately 1 in every 3ve births male to female ratio is 4 to 1. ALe of’ incidence is 3-6 weeks.
Diagnosis of hypertrophic pyloric stenosis depends upon the classic clinical features of projectile non bilious vomiting, the presence of palpable pyloric mass, visible gastric waves on the abdomen.
Radiographic examination with either an upper gastrointestinal series or abdominal ultrasonography should be reserved for those patients in whom the pyloric mass can not be palpated.
Rammestcdt in 1912 was the first who described the surgical procedure of pyloroinyotorny as a treatment of congenital pyloric stenosis and from that date Rarnmestedt’s pyloromyotomy is universally accepted as the preferred operation. -
This procedure can be performed though a number of different approaches. The classical approach is an upper right transverse skin incision. Upper umbilical fold incision is a new approach that was proposed to get an easier exposure to the pyloric mass with a better cosmetic results.
