Background: Despite much initial enthusiasm, umbilical pyloromyotomy h
as failed to achieve widespread popularity. This mostly relates to dif
ficulty with delivering the pyloric tumour through the relatively smal
l incision. Method: A new technique for umbilical pyloromyotomy is des
cribed in which a circumumbilical skin incision with a right lateral e
xtension is combined with transverse division of the linea alba and pa
rt of the right rectus muscle. The pyloric tumour is easily delivered
to the skin surface through this generous minilaparotomy, After muscle
closure the lateral skin extension is swung medially as described and
incorporated within the umbilical scar. Results: We report our experi
ence of 30 cases in which this technique was successfully employed. Th
e pyloromyotomy was done on the surface in all cases and the resulting
scar was barely visible in the folds of the umbilicus.
