Vertical Umbilical Incision Achieves Better Cosmesis Than Periumbilical Incision in Neonates and Infants.

PURPOSE

The transumbilical approach is widely used for minimally invasive surgery in children. We compared herein the postoperative cosmesis between two types of transumbilical approach: a vertical incision versus periumbilical incision.

METHODS

Patients with a transumbilical laparotomy before age one year were prospectively enrolled between January 2018 and December 2020. A vertical incision or periumbilical incision was chosen at the surgeon's discretion. After excluding patients receiving a relaparotomy via another site, a questionnaire about the appearance of the umbilicus was completed by the patients' guardians at postoperative month 6 to assess satisfaction and determine the visual analog scale score. A photograph of the umbilicus was taken while the questionnaire was being administered for later assessment by surgeons blinded to the scar and umbilical shape.

RESULTS

Forty patients were enrolled; 24 patients received a vertical incision while 16 received a periumbilical incision. The incision length was significantly shorter in the vertical incision group (median: 2.0; range: 1.5-3.0 cm vs. median: 2.75; range: 1.5-3.6 cm) (p = 0.001). The patients' guardians reported significantly higher satisfaction (p = 0.002) and higher scores on the visual analog scale (p = 0.046) in the vertical incision group (n = 22) than in the periumbilical incision group (n = 15). The surgeons' evaluation was associated with significantly more patients with a vertical incision than with a periumbilical incision achieving a cosmetically preferable outcome, including an invisible or fine scar and a normal umbilical shape.

CONCLUSION

A vertical umbilical incision can provide better postoperative cosmesis than a periumbilical incision.
