[Laparoendoscopic single-site surgery for male pseudohermaphroditism: the initial report].

OBJECTIVE: To evaluate the therapeutic effect of laparoendoscopic single-site surgery (LESS) for treatment of male pseudohermaphroditism. METHODS: A 17-year-old patient with male pseudohermaphroditism and a female social sex was admitted. According to the request by the patient and the relatives for a female gender, LESS vaginoplasty and cryptorchidectomy were performed using a single multilumen port inserted through a 2.5 cm incision below the umbilicus, followed by reconstruction of the perineal region by open surgery. RESULTS: The total operative time was 7 h, and the LESS procedure lasted for about 3.5 h. No other port incision was needed. The estimated intraoperative blood loss was 400 ml. No electrolyte or metabolic acid-base balance disorders were observed perioperatively. In the follow-up examination at 6 months after the operation, the reconstructed vagina healed smoothly without obvious contraction or fixation failure, and the perineal region showed good appearance. CONCLUSION: With minimal invasiveness, LESS surgery produces good cosmetic effect and allows rapid postoperative recovery, thus may become a promising alternative to the management of pseudohermaphroditism.
