Congenital pyloric stenosis: a modified umbilical incision for pyloromyotomy.

Thirty-two patients underwent a pyloromyotomy via an umbilical incision; in 11 a modified umbilical approach was used to facilitate delivery of the pyloric mass. Incisions are made in the skin fold of the upper half of the umbilicus and at the midline, joining the two at the top. The skin incision is closed by upper umbilical translocation with a very good cosmetic result. This incision allows easy access to the pylorus and provides more convenient exposure. The absence of traction on the retractors avoids tissue ischemia, which leads to wound abscess development.
