Reconstruction of Cloacal Defect: Switch Operation - A New Approach.

INTRODUCTION

Reconstruction of a cloacal defect in a girl is often difficult and complicated.[1] This is most often done either by the sacro-perineal route or through the posterior sagittal route.[2] The procedures may involve total mobilization of the cloaca with or without the creation of a lower vagina with the help of a loop of vascularized bowel.[3] In our approach, such defects can be corrected using the lower anorectum for the creation of a lower vagina and abdominoperineal pull-through of the proximal divided bowel. This method can be used both in short and long common channel cloaca.

MATERIALS AND

METHODS

We have used this procedure in one patient of posterior cloaca and four patients of anterior cloaca. These operations were done in patients of 1 year and 6 months to 4 years. Only one patient is waiting for the closure of the colostomy.

RESULTS

In all the cases, the urethra, the vagina, and the anus were successfully separated.

CONCLUSION

This operation restores normal pelvic anatomy and physiology with minimal mutilation of the pelvic floor.
