Objective:To investigate the application of pedicled or perforator flaps transfer in the stage Ⅰ tissue defect repair after vulvar cancer surgery.Methods:From January 2005 to December 2023, 20 patients with vulvar cancer who underwent extensive episiectomy or extended episiectomy±inguinal lymph node resection+vulvar defect flap transfer were collected in Huanxing Cancer Hospital of Chaoyang District and Cancer Hospital and Peking Union Medical College, Chinese Academy of Medical Sciences. The survival status, appearance structure, sexual function satisfaction, tumor recurrence, and survival were analyzed.Results:(1) The median age of the 20 patients was 59 years (ranged: 29-73 years). There were 14 patients with recurrence and 6 patients with initial treatment. Pathological types: 14 cases of squamous cell carcinoma, 4 cases of Paget′s disease, 1 case of malignant melanoma, 1 case of adenoid cystic carcinoma (salivary gland type carcinoma). (2) Among the 20 patients, 6 cases underwent extensive episiotomy and 14 underwent extended episiotomy (1 of them underwent extensive excision of inguinal masses). Simultaneous inguinal lymphadenectomy (or dissection) were performed in 11 cases, including 7 cases of bilateral inguinal lymph node resection (or dissection) and 4 cases of unilateral inguinal lymph node resection (or dissection). Flap source: pedicled flap in 12 cases, perforator flap in 8 cases. All the 20 patients were removed at 10-14 days after operation, and all of them survived with rosy skin color and good elasticity. Seventeen cases of transferred flaps healed at stage Ⅰ, 2 cases healed at about 6 weeks due to incision leakage, and 1 case healed at 6 weeks after incision infection debridement. Six months after the operation, 2 cases felt that the pubic mound was thick and swollen. The other 18 cases showed vulva fullness and elasticity, no displacement of urethral opening, no deviation of urethra during urination, no stenosis of vaginal opening, no vulvar scar pain. In addition to 1 unmarried 29-year-old patient and 6 patients over 65 years old who had no sexual life before and after surgery, the other 13 patients had normal sexual life after surgery. (3) The follow-up period were 6 to 100 months, and 9 cases (45%, 9/20) relapsed during the follow-up period. There were 5 deaths (25%, 5/20), who were due to recurrence of vulvar cancer. The 5-year survival rate of 20 patients was 75%, including 83% in 6 patients with initial treatment and 71% in 14 patients with recurrence and reoperation.Conclusions:The combination of flap transfer for episioplasty with vulvar cancer surgery does not affect the wound healing. Because the external structure of the vulva is repaired, it could effectively improve the local wound healing ability and improve the organ function, and has good clinical application value.
