Have any gastro or colorectal issue?
If you’re struggling with internal haemorrhoids that cause discomfort, bleeding, or prolapse, Transanal Haemorrhoidal Dearterialisation (THD) may offer a practical and less invasive way forward. Rather than removing tissue, THD treats the root causes such as excessive blood flow and prolapse, through precise techniques designed to restore normal function and relieve symptoms effectively.
What Is THD (Transanal Haemorrhoidal Dearterialisation)?
THD is a minimally invasive procedure performed by a colorectal surgeon to address internal haemorrhoids. It’s built around two steps: dearterialisation and mucopexy (or haemorrhoidopexy), both aimed at reducing blood supply and repositioning prolapsed tissue.
- DearterialisationUsing a special Doppler-guided device, your surgeon identifies the small arteries feeding the haemorrhoids. These arteries are gently tied off with dissolvable sutures, cutting off excess blood flow so the swollen tissue can shrink naturally over time.
- Mucopexy (Prolapse Lift)In the event of a prolapse, this step helps reposition the tissue that has slipped downward. The surgeon places a series of fine stitches to lift it back into place, restoring its normal structure inside the rectum where pain sensation is minimal.
Who Is THD Suitable For?
THD is typically recommended for people with Grade II or Grade III internal haemorrhoids, especially when non-surgical treatments haven’t provided lasting relief.
- Patients with Grade II Haemorrhoids: Piles that prolapse during bowel movements but retract on their own.
- Patients with Grade III Haemorrhoids: Piles that need to be gently pushed back after passing stools.
For Grade IV haemorrhoids, where tissue remains prolapsed, a traditional haemorrhoidectomy may still be required. However, in selected cases, THD can be a feasible option that may lessen recovery time and discomfort.
If you've been told you may need surgery for haemorrhoids, THD could offer a gentler alternative with a quicker return to daily life.
ENQUIRE HEREWhat Are the Benefits of THD?
Patients often consider THD because it strikes a balance between effectiveness and comfort. Its benefits include:
- Minimally Invasive: The procedure doesn't involve cutting or removing tissue, preserving the structure of the anal canal.
- Less Pain Compared to Conventional Surgery: Since it's done above the dentate line (an area with minimal pain sensation), most people experience only mild soreness afterwards.
- Faster Recovery: You can typically go home the same day or within 24 hours, and resume work or light activities within several days.
- Reduced Risk of Complications: THD reduces the likelihood of bleeding, wound issues, or scarring compared to conventional surgery.
- Preservation of Anal Anatomy: THD preserves the structure of the anal cushions, which are important for maintaining continence and normal function.
If you've been living with persistent Grade II or III haemorrhoids, it may be time to explore whether THD is the right treatment for you.
Contact UsFrequently Asked Questions
Is the THD procedure painful?
No. It’s done under anaesthetic, so you won’t feel anything during surgery. Afterwards, you may experience mild soreness rather than severe pain, typically controlled with simple medication.How long does recovery take after THD?
Clinical studies and long-term follow-up studies show that THD is a reliable and effective option for managing Grade II and Grade III haemorrhoids, achieving outcomes comparable to traditional surgery. Many patients report lasting relief from bleeding, swelling, and prolapse. The combination of effective symptom control, quicker recovery, and reduced post-operative discomfort contributes to its consistently high satisfaction rates.What are the alternatives to THD?
Depending on severity, alternatives include conservative management (dietary changes, topical treatments), office procedures (rubber band ligation, sclerotherapy), or traditional surgery.How soon can I return to work after THD?
Most people can resume light duties or office work within two to four days, while those with more physically demanding jobs may need about a week before returning. This quick recovery is one of the key advantages of the THD procedure, allowing you to get back to your usual routine with minimal disruption.
As awareness of the technique grows, THD treatment in Singapore has become increasingly accessible. Many colorectal specialists are now trained in this approach, making it easier to receive effective, minimally invasive care close to home.
