A new incision for pyloromyotomy.

Over the past two years forty infants with hypertrophic pyloric stenosis have been operated on using a supraumbilical transverse midline skin incision with retraction of the two rectus muscles apart. This incision has given us good exposure, has improved the delivery of the pylorus, produced a strong closure, and given a good cosmetic result. We propose this incision as an alternative to be used in the operative approach to the pylorus in the treatment of hypertrophic pyloric stenosis.
