Outcome of Single Stage Correction of High Variety of Anorectal Malformation.

The standard treatment of high variety anorectal malformation (ARM) is the staged approach. A growing interest in one stage correction of high variety ARM was noted recently. The aim of this study was to examine the feasibility, safety and outcome of single stage correction of High variety ARM. This prospective study was carried out in the Department of Paediatric Surgery, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2012 to September 2013. It was conducted among 30 patients, all having high ARM. The type of ARM was diagnosed by clinical examinations and imaging studies like Invertogram and Transperineal USG. Other associated congenital anomalies were excluded. Out of 30 patients 11(36.67%) were male and 19(63.33%) were female. The age incidence ranges from 2 days to 5 months with the mean±SD age 1.70±1.63 months. The type of fistula present along with ARM in male varies from rectobulber urethral fistula, recto prostatic urethral fistula, recto vesical fistula and in one case without any fistula. Type of fistula was rectovestibular, rectovaginal and one cloacal malformation among the female patients. The treatment modalities in male patients vary in transabdominal pull through anorectoplasty and PSARP, in which the former was done more (72.73%). In case of female patients, treatment modalities vary in transabdominal pull through and anorectoplasty and transfistulous anorectoplasty, with the later done more (52.63%). Regarding post operative complications, there was 1(14.29%) wound infection in male and 1(33.33%) in female, partial wound disruption in 1(14.29%) male patient, mucosal prolapse 2(28.57%) in male and 1(33.33%) in female, anal stenosis 1(14.29%) in male and 1(33.33%) in female, perianal soiling in 1(14.29%) male patient. All the complications were treated by adopting various measures. One stage correction of High variety ARM in both male and female patients is technically feasible. The safeties of this approach depend on the adherence to strict inclusion criteria. The early post operative complications are acceptable and can be managed successfully.
