Patient and parental scar assessment after single incision versus standard 3-port laparoscopic appendectomy: Long-term follow-up from a prospective randomized trial

article i nfo Single-incision Laparoscopy Appendectomy Cosmetic Pediatrics Background: Single site laparoscopy for appendectomy is a technique with several case series suggesting a cosmetic advantage, but without prospective comparative data. We conducted a prospective, randomized trial comparing single site laparoscopic appendectomy to the standard 3-port approach, including scar assessment at early and long-term follow-up. Methods: Enrolled patients over 12 years old and parents of patients less than 12 years old were asked to complete the validated Patient Scar Assessment Questionnaire (PSAQ) at early follow-up around 6 weeks and by phone after 18 months. The PSAQ consists of 4 scored subscales: Appearance, Consciousness, Appearance Satisfaction, and Symptom Satisfaction. Each subscale has a set of questions with a 4-point categorical response (1 = most favorable, 4 = least favorable). The sum of the scores quantifies each subscale. Results: Early questionnaires were obtained from 98 3-port and 100 single-site patients with the single-site approach producing superior overall scar assessment (P = 0.003). By telephone follow-up, questionnaires were completed by 49 3-port and 56 single-site patients at a median of 25 (18-32) months. In this longer- term follow-up, overall scar assessment was not significantly different between groups (P = 0.06). Conclusion: Patients or parents express superior scar assessment with the single site approach at early follow- up, but this difference disappears in the long-term.
