Transanal Hemorrhoidal Dearterialization (THD)

Here you can find information to help you better understand your options if you are considering THD for colorectal diseases!

Bangkok-Phuket Colorectal Disease Institute provides minimally invasive surgery to treat hemorrhoids called transanal hemorrhoidal dearterialization. Below is the basic information of Transanal Hemorrhoidal Dearterialization, you can click on the topic to read more about THD.

Transanal Hemorrhoidal Dearterialization (THD)

 

What is Transanal Hemorrhoidal Dearterialization?

Health Knowledge

THD is a surgical procedure for the treatment of internal hemorrhoids. THD uses a specially developed anoscope combined with a Doppler transducer to identify the hemorrhoidal arteries (originating from the superior rectal artery) 2-3 cm above the dentate line. Once the superior rectal arteries are isolated with the doppler, a suture ligation is performed to effectively decrease the blood flow to the hemorrhoidal plexus. In case of redundant prolapse, the prolapsed mucosal membrane is lifted and sutured (with the last suture minimum 5 mm above the dentate line), repositioning hemorrhoidal cushions in situ. This is different from a traditional hemorrhoidectomy, which focused on excising the hemorrhoidal bundle. In this procedure there is no tissue that is excised. Because the suture line is above the dentate line, post-operative pain is minimized for patients. THD can be performed with general anesthesia (going to sleep).

 

How the Transanal Hemorrhoidal Dearterialization works?

Health Knowledge

Step 1: THD uses a Doppler Ultra­sound, placed into the rectum, to locate the specific arteries which cause bleeding.

Step 2: Once the arteries have been located, the surgeon sutures the problematic artery(s) closed, resulting in an immediate reduction in swelling and bleeding. This is completed without cutting or removal of any tissue.

Step 3: Last, the surgeon will reposition any prolapsed or hanging tissue outside the anus to its natural anatomical position inside the anal canal with self-absorbing sutures.

If necessary a hemorrhoidopexy can be performed at the same time to repair a hemorrhoidal prolapse (a hemorrhoid that is protruding from the anus). Again, this is done with suture and no excision of tissue. This repair restores and “lifts” the hemorrhoidal tissue back to its anatomical position.

The entire procedure is performed above the dentate line of the rectum so that there is minimal discomfort. The procedure takes about 30 minutes and is offered as an out-patient surgery.

 

Why Transanal Hemorrhoidal Dearterialization?

Health Knowledge
  • Minimally Invasive

  • Minimal discomfort

  • No tissue is cut or excised

  • Little pain

  • Outpatient operation and return home same day.

  • Quicker return to activities (often within 4 days of the procedure)

  • THD treats the source of Hemorrhoid disease, not the symptoms

  • Fewer follow-up appointments

 

Risk of Transanal Hemorrhoidal Dearterialization (THD) surgery

Health Knowledge

As with any surgical procedure, there are potential risks involved. The minor and temporary risks associated with THD include bleeding, mucous discharge, and urinary retention.
