A comparison of 99 consecutive vaginal reconstructions: an outcome study.

Abstract

This study compares the outcome of Singapore flap, vertical rectus abdominis musculocutaneous flap (VRAM), and gracilis musculocutaneous flap vaginal reconstruction. A retrospective review of 99 consecutive patients with complete vaginal defects was conducted at the Mayo Clinic from January 1988 to October 2001. All possible complications were determined for each of the 3 reconstructive techniques, along with the effects of radiation and smoking on the respective complication rates. Preoperative and postoperative sexual function and adequacy were compared between each group. Ninety-nine patients ranging in age from 19 to 80 years (mean, 51.6 years) were compared, with a mean follow-up of 28.9 months. Forty-one VRAM, 13 gracilis, and 45 modified Singapore flaps were used for vaginal reconstruction. The majority was due to acquired vaginal defects due to recurrent pelvic malignancy. The overall complication rate was lower following VRAM than either gracilis or Singapore flap reconstructions (13/41, 31.7%; 8/13, 61.5%; and 21/45, 46.7%, respectively). The flap specific complication rate was least in the VRAM group (9/41, 22%; 7/13, 53.8%; and 17/45, 37.8%, respectively). The VRAM had a significant protective effect against the development of postoperative small bowel obstruction. Preoperative sexual activity predicted postoperative activity in 75 of 88 patients (85.2%) and was not affected by the type of reconstruction, although more patients with a Singapore flap required vaginal dilatation to maintain patency. In conclusion, the VRAM has a lower overall and flap-related complication rate compared with either gracilis or Singapore flap reconstruction. It has become our vaginal reconstructive flap of choice.
