A classification system and reconstructive algorithm for acquired vaginal defects.
Although multiple flaps have been used for vaginal reconstruction, a logical approach to reconstruction of these often complex defects has not been described. The objective of this study was to establish a classification system for acquired vaginal defects and to develop a reconstructive algorithm derived from this system. This study is a retrospective review of a 7-year experience with 51 flaps in 37 consecutive vaginal reconstructions. Twenty-two partial defects and 15 circumferential defects were reconstructed in 35 patients. Average patient age was 48 years (range, 19 to 69 years). Of the 22 patients with partial vaginal defects, six involved primarily the anterior and lateral wall and 16 the posterior vaginal wall. Among the 15 patients with circumferential defects, four included only the upper two-thirds of the vagina and 11 encompassed the entire vagina. On the basis of these defects, a classification system was developed. Partial defects involving the anterior or lateral vaginal wall were classified as type IA defects and were reconstructed primarily with pedicled Singapore fasciocutaneous flaps. Partial defects involving the posterior wall were classified as type IB and were reconstructed with pedicled rectus abdominis myocutaneous flaps. Circumferential defects involving the upper two-thirds of the vagina were classified as type IIA defects and were reconstructed with a rolled rectus flap or, less commonly, sigmoid colon (one patient). Total circumferential defects, type IIB, were reconstructed largely with bilateral gracilis flaps. Six patients had major complications, including one perioperative death, one complete flap loss, one partial flap loss, and three pelvic abscesses. Three patients had minor complications that included delayed wound healing and donor-site infection. Vaginal defects can be categorized into one of four types on the basis of the location and extent of resection. Flap selection is determined on the basis of the type of defect. Using this algorithm, immediate vaginal reconstruction with pedicled regional flaps can be performed with minimal patient morbidity and few surgical complications.
