Abstract: Objective To investigate the possibility of operation for treating anorectal malformation based on laparoscopically-assisted anorectal pullthrough (LAARP). Method From March 2010 to June 2015, 51 patients were performed LAARP . There were 48 boys and 3 girls aged from 4 to 24 months and weight ranged from 4.0 to 12.5kg. 36 colostomies were placed in transverse colon and 14 were in sigmoid colon, and 1 was in ileum. Results LAARP and colostomy closure were taken simultaneously in 41 patients.Colostomy were closed in 10 patients 3 to 6months later. The operation time were from120 to 230 minutes. The early complications included 10 cases of wound infection of which colostomy closure were taken simultaneously, one case of pelvic infection, 8 cases of prolapsed. In the follow-up period of 5 to 68 months, one patient complicated with esophageal atresia and tracheoesophageal fistula died of asphyxia. 5 patients lost of follow up. 44 patients had voluntary vowel movements while 2 patients could not be judged due to dysgnosia. 10(23%) patients had some degree of soiling, and 6 patients had constipation. No patients needed enema treatment. Conclusions LAARP is a less invasive procedure，and it can provide an excellent visualization. The technique is simple, safe and feasible. More studies to prevent the complications such as rectal mucosal prolapse should carried out.
