Over the past two years forty infants with hypertrophic pyloric stenos
is have been operated on using a supraumbilical transverse midline ski
n incision with retraction of the two rectus muscles apart. This incis
ion has given us good exposure, has improved the delivery of the pylor
us, produced a strong closure, and given a good cosmetic result. We pr
opose this incision as an alternative to be used in the operative appr
oach to the pylorus in the treatment of hypertrophic pyloric stenosis.
