Why Patients May Consider Dr. Theerapong
Experience with complex reconstructive surgery
Secondary sigmoid colon vaginoplasty is more complicated than many primary vaginoplasty procedures. Previous surgery can leave scar tissue, altered anatomy, reduced tissue availability, vaginal stenosis, loss of depth, false passages or previous wound complications.
Dr. Theerapong’s background in plastic and reconstructive surgery supports the careful evaluation and individualized planning required for complex revision cases. Each patient’s remaining vaginal tissue, external genital anatomy, scar pattern and previous surgical history must be assessed before a suitable revision technique can be recommended.
Individualized surgical evaluation
Not every patient experiencing loss of vaginal depth requires sigmoid colon vaginoplasty. Depending on the examination findings, some patients may be better suited to scar release, revision of the vaginal entrance, skin grafting, peritoneal reconstruction or another technique.
During consultation, Dr. Theerapong evaluates factors such as:
- The technique used during the original vaginoplasty
- Current vaginal depth and width
- The severity and location of stenosis
- Remaining healthy penile or scrotal tissue
- Previous graft loss or tissue necrosis
- History of infection or wound separation
- Possible rectovaginal or urinary fistula
- External vulvar appearance
- Clitoral sensation
- Urethral position and urinary symptoms
- Previous abdominal or intestinal surgery
- The patient’s medical history and reconstructive goals
The objective is to determine whether sigmoid colon reconstruction is medically appropriate and whether additional procedures, such as labiaplasty, introital revision, scar correction or urethral revision, should be performed during the same operation or in a later stage.
Experience serving international patients
Bangkok is a major destination for international gender-affirming surgery. Dr. Theerapong’s professional profile states that he has treated patients from different countries, which can be especially important for patients who require coordinated consultations, medical testing, hospital admission, accommodation, postoperative nursing and follow-up before returning home.
International patients should receive a clear plan covering:
- Preoperative medical clearance
- Review of previous surgical records
- Required diagnostic examinations
- Hospital admission and anticipated stay
- Accommodation during recovery
- Postoperative wound care
- Vaginal dilation training
- Management of intestinal mucus
- Follow-up examinations in Bangkok
- Fitness-to-fly clearance
- Emergency arrangements after returning home
Patient-centered communication
Revision surgery can be physically and emotionally challenging, particularly for patients who have already experienced loss of depth, severe stenosis, chronic pain or complications from a previous vaginoplasty.
A comprehensive consultation should allow the patient to discuss what happened after the original surgery, what problems are currently present and what outcome they hope to achieve. Dr. Theerapong’s treatment planning focuses on evaluating the patient’s individual anatomy and discussing realistic surgical options rather than recommending the same procedure for every case.
A Comprehensive Surgical Team Is Essential
Secondary sigmoid colon vaginoplasty involves both genital reconstruction and abdominal bowel surgery. Even when an experienced plastic and reconstructive surgeon leads the vaginal reconstruction, appropriate colorectal or general surgical support may be necessary for the selection of the sigmoid segment, bowel anastomosis and management of intestinal complications.
The procedure should be performed in a suitably equipped hospital with access to:
- Qualified anesthesia care
- Colorectal or general surgical support
- Inpatient nursing
- Diagnostic imaging
- Laboratory services
- Emergency abdominal surgery
- Blood transfusion services
- Intensive-care support when medically necessary
- Structured postoperative follow-up
Patients should confirm which surgeons will participate in their operation and which hospital will manage any complications.
What Patients Should Understand Before Choosing Surgery
Choosing Dr. Theerapong or any other surgeon does not guarantee a specific vaginal depth, appearance, level of sensation, lubrication, complication-free recovery or sexual outcome.
Secondary sigmoid colon vaginoplasty remains a major procedure with possible risks including:
- Bleeding and infection
- Bowel leakage
- Intestinal obstruction
- Fistula
- Loss of blood supply to the sigmoid segment
- Vaginal entrance narrowing
- Recurrent stenosis
- Vaginal prolapse
- Persistent mucus discharge
- Abdominal scarring
- Need for additional revision surgery
Patients should make their decision only after receiving a personal examination, reviewing alternative techniques and understanding the expected recovery, dilation requirements, long-term mucus management and possible complications.
Schedule a Personalized Evaluation
Patients considering secondary sigmoid colon vaginoplasty with Dr. Theerapong Poonyakariyagorn, MD, in Bangkok, Thailand, should prepare their previous operative report, medical records, photographs when appropriate, current dilation history and details of any complications.
A comprehensive evaluation allows Dr. Theerapong and the surgical team to determine whether secondary sigmoid colon vaginoplasty is the most appropriate reconstructive option and to develop a surgical plan based on the patient’s anatomy, health, previous procedures and long-term goals.
