Objective The aim of the present study was to evaluate the surgical and functional outcome of the laparoscopic-aided transanal pull-through procedure for the management of Hirschsprung’s disease (HD). Patients and methods The study included 17 patients older than 12 months. Diagnosis of HD relied on the inability of the patients to relax the anal internal sphincter in response to colonic extension on anorectal manometry. The laparoscopic part entailed transition zone identification, seromuscular biopsy for fresh frozen histopathology, and sigmoid and rectal mobilization up to 1 cm down the peritoneal reflection. The transanal part included mobilization of the rectal lower by 2 cm, resection till the ganglionic segment, and anastomosis. Patient outcome included evaluation of fecal consistency, frequency of soiling, and presence of perianal skin excoriation at 1, 3, and 6 months after the procedure. Colonic manometry and functional outcome evaluation according to qualitative clinical Holschneider scoring were carried out at 1 and 6 months after the procedure. Results One (5.9%) patient required open conversion for dissection of thick adhesions. Frequency of patients that passed formed stool and free of soiling increased progressively till the end of 6 months after the procedure. At 1 month after the procedure, six patients developed perianal skin excoriation, but all were free by the sixth postoperative (PO) month. Manometric pressure measures at 3 and 6 months after the procedure were significantly higher compared with the preoperative measures, with significant difference in favor of 6-month measures. At 6 months after the procedure, Holschneider scoring was significantly higher compared with that at 1 month, and 10 patients had a score of 14. No surgery-related complications were detected. Conclusion Laparoscopic-aided transanal pull-through is a feasible procedure for the management of children older than 12 months and who have HD. The procedure is safe with minimal PO complications, which are gradually resolved within 6 months PO.
