Objective:To evaluate the clinical efficacy and the mid- and long-term follow-up outcomes of transanal anaplasty for treating rectovestibular fistula.Methods:The clinical data of 68 female infants diagnosed with rectovestibular fistula undergoing transanal anoplasty at the Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from Oct 2014 to Dec 2023 was collected. Postoperative complications, perineal and anal appearances, and defecation function of postoperative children aged 3 years or older were recorded.Results:After surgery 68 children followed-up for 6 months of recent with short-term complications in 6 cases, including 3 cases of incision infection, 2 cases of rectal mucosal prolapse, and 1 case of anal stenosis. Rintala score was (18.65±1.99). Twenty-five children underwent anorectal manometry, no significant differences were observed in the maximal systolic pressure of the anal canal( t=-0.596, P=0.563) and the maximum systolic time( t=-0.183, P=0.854). The resting pressure( t=-3.050, P=0.005), functional length( t=2.696, P=0.012), and positive rate of rectal anal inhibitory reflex( χ2=6.382, P=0.012) of the anal canal were significantly lower than those of the normal group( P<0.05). Conclusions:Transanal anaplasty for the treatment of rectovestibular fistula in girls has a low incidence of complications. It results in a normal perineal body appearance, good anal bowel control, and high quality of life.
