Vaginal replacement in children and young adults

Area of Science:

• Reconstructive surgery
• Pediatric surgery
• Gynecologic surgery

Background:

• Vaginal absence in pediatric patients often stems from congenital issues like Mayer-Rokitansky syndrome or arises post-treatment for pelvic tumors (e.g., rhabdomyosarcoma) or gender reassignment.
• Surgical reconstruction is necessary for patients with vaginal agenesis to enable sexual function and improve quality of life.

Purpose of the Study:

• To evaluate the outcomes and patient satisfaction of using bowel segments for vaginal replacement in children and young adults.
• To compare the efficacy of different bowel segments (colon vs. small bowel) for neovagina creation.

Main Methods:

• A retrospective review of 31 patients (ages 1-20) who underwent vaginal replacement using bowel segments between 1980 and 1996.
• Diagnoses included Mayer-Rokitansky syndrome, androgen insensitivity syndrome, rhabdomyosarcoma, and others.
• A questionnaire assessed postoperative sexual function and satisfaction in 26 patients.

Main Results:

• Thirty-three bowel segments (20 sigmoid colon, 8 ileum, 5 cecum) were used for reconstruction.
• Twenty patients (65%) were sexually active; 8 were married.
• Complications included stenosis (6/31) and prolapse (1/31), with 3 patients requiring secondary procedures.

Conclusions:

• Isolated bowel segments, especially sigmoid colon, provide excellent tissue for vaginal replacement.
• Sigmoid colon is preferred over small bowel due to mesentery length, facilitating tension-free anastomosis.
• Bowel segment vaginoplasty supports sexual activity more effectively than traditional methods like dilation or skin grafts.
