Umbilical fold incision for pyloromyotomy.

A 5-year experience with 100 infants undergoing pyloromyotomy was reviewed. Fifty infants who had a standard right upper quadrant incision were compared with 50 infants in whom an umbilical fold incision was used. The groups did not differ significantly with respect to length of operating time, hospital stay, or intraoperative complications. Wound complications were infrequent and minor in both groups. The umbilical fold incision permits excellent access to the pylorus, while leaving an almost undetectable scar.
