Information on Colon Vaginoplasty

Overview of Colon Vaginoplasty

Colon vaginoplasty is a surgical procedure used to create or reconstruct a vaginal canal using a segment of the colon. This method can be utilized as an alternative to skin grafts during sex reassignment surgery (SRS) or as a corrective measure for patients who experience unsatisfactory vaginal depth post-SRS.

Surgical Technique

During colon vaginoplasty, a segment of the sigmoid colon (approximately 20 cm) is selected. One end of the colon graft is closed while the other end is left open and is slid through the vaginal tunnel to be sutured to the vaginal opening.

Indications for Colon Vaginoplasty

A: Primary Colon Vaginoplasty (Male to Female SRS with Colon Graft)

For primary sex reassignment surgery, Dr. Chettawut typically recommends the standard SRS (Non-penile inversion SRS with skin graft technique) over primary colon vaginoplasty to avoid potential abdominal complications. However, primary colon vaginoplasty may be considered in selective cases with the following criteria:

  • Patients must be younger than 45 years old.
  • Patients must weigh less than 80 kg.
  • Patients’ BMI must be less than 28.
