Background/Purpose: Performing a pyloromyotomy through a supraumbilical skin fold incision will leave an almost invisible scar and therefore has definitive cosmetic advantages. This alternative approach may be related to technical difficulties in delivering a large pyloric tumor when compared with the conventional pyloromyotomy through a right upper quadrant incision. However, in situ (intraabdominal) myotomy can help overcome this inconvenience. Methods: Of 122 cases of infantile hypertrophic pyloric stenosis operated on between January 1990 and August 1996, 29 underwent a pyloromyotomy performed intraabdominally through the umbilical route. The medical records of these babies were reviewed. Results: Twenty-three boys and six girls (median age, 30 days; range, 17 to 70 days) underwent surgery. The median hospital stay was 2.5 days. There were two intraoperative technical complications (small mucosal perforation) and one postoperative wound complication (abscess formation) requiring local drainage. Conclusions: In situ pyloromyotomy through the umbilical route is an elegant alternative in cases of a large pyloric tumor.
