[Comparative study on laparoscopic vaginoplasty using pedicled ileal and sigmoid colon segment transfer]

Area of Science:

• Surgical reconstruction
• Gynecological surgery
• Minimally invasive surgery

Background:

• Vaginal agenesis requires reconstructive surgery.
• Intestinal segments are utilized for neovagina creation.
• Laparoscopic techniques offer potential benefits in reconstructive surgery.

Purpose of the Study:

• To evaluate the clinical outcomes of laparoscopic vaginoplasty using pedicled ileal and sigmoid colon segments.
• To compare the efficacy and safety of ileal versus sigmoid colon flaps in vaginoplasty.

Main Methods:

• Retrospective study of 105 patients undergoing laparoscope-assisted vaginoplasty from 2004-2009.
• Comparison of operative time, blood loss, recovery, and neovagina characteristics between ileal and sigmoid colon flaps.
• Assessment of short-term and long-term complications and functional outcomes.

Main Results:

• Successful vaginoplasty in all 105 cases (48 ileal, 57 sigmoid colon).
• Ileal vaginoplasty had significantly shorter operation times, less blood loss, and faster bowel recovery compared to sigmoid colon vaginoplasty.
• Postoperative complications included intestinal obstruction (sigmoid colon), urethral stenosis, and rectovaginal fistula (ileal).
• All neovaginas achieved adequate length and width; 55 patients reported satisfactory sexual function, with 6 cases of vaginal stenosis (5 ileal, 1 sigmoid colon).

Conclusions:

• Laparoscope-assisted vaginoplasty with pedicled ileum or sigmoid colon segments are effective for vaginal construction.
• Ileal flaps offer advantages in reduced operative time and blood loss.
• Sigmoid colon flaps may be associated with a lower incidence of vaginal stenosis.
