AbstractBackground: Laparoscopic anorectoplasty was introduced in 2000, but the procedure has not yet gained universal acceptance. Previous studies, including ours, reported satisfactory early postoperative outcome as compared with posterior sagittal anorectoplasty (PSARP), but mid- to long-term results are not available. Here, we aim to evaluate the mid- to long-term defecative function in these patients. Materials and Methods: A retrospective study was carried out and included all patients who underwent laparoscopic-assisted anorectoplasty for high-/intermediate-type imperforate anus between 2001 and 2005. Their degree of continence was graded according to the Krickenbeck classification and compared with historical controls treated with PSARP. The results were compared using χ 2 test, and P <.05 was considered statistically significant. Results: There were 18 patients who underwent laparoscopic anorectoplasty (LAR) in the study period. They were compared with 20 historical PSARP patients. For defecation sensation, 16 of the 18 LAR patients were positive, whereas there were 16 of 20 PSARP patients. Eight LAR patients were clean without any fecal soiling or incontinence (11/20 PSARP). Only 3 of 18 LAR had constipation as compared with 7 of 20 PSARP. The need for rectal enema for evacuation was seen in 1 of 20 LAR patients and 2 of 20 PSARP patients (for all categories, P >.05). Conclusions: Mid- to long-term follow-up study revealed satisfactory defecative function for patients with high-/intermediate-type imperforate anus after LAR. The outcome is at least as good as PSARP. Longer term follow-up with larger sample size is necessary to demonstrate the benefits of LAR over PSARP. © 2011 Elsevier Inc.
