OBJECTIVE: Bowel vaginoplasty is particularly difficult in patients who are extremely obese or those with an android pelvis. This report evaluates the use of the Yang-Monti principle as a viable alternative in the reconstruction of these patients.
METHODS: Upon retrospective chart review of patients who underwent bowel replacement vaginoplasty between 1980 and 2008, 4/60 were identified who underwent the Yang-Monti modification. The neovagina was created with an 8‒10-cm segment of descending colon which was detubularized and then retubularized using the Yang-Monti principle. This was sewn in place in the perineum. Outcome was evaluated by physical examination data and clinical information on postoperative sexual function.
RESULTS: Three of the four patients had an XY karyotype and an android pelvis, and of these two were failures of previous ileovaginoplasties and one was a failed colovaginoplasty. The fourth was a case of primary mullerian failure (XX) in a morbidly obese individual. All four were discharged without complication following surgery. With a median follow-up of 6 years (range 4-9), none showed evidence of introital stenosis or required dilation. Two were engaged in vaginal intercourse at last consultation, and they reported vaginal length was adequate. No further procedures were required in any of the patients at the end of the follow-up period.
CONCLUSION: The Yang-Monti modification, when used as an adjunct to colovaginoplasty, can be an effective reconstructive technique in this subset of patients. It allows for lengthening of the neovagina, without perpetuating tension on the vascular pedicle.
