Hemorrhoids Happen!

Hemorrhoids are not a frequently discussed topic. Most people simply tolerate the problem and are often frightened by the thought of traditional surgery. It is estimated that 50% of us will, at some point in their lives, suffer from hemorrhoids, with bleeding, swelling, pain or prolapse.

Now you can find relief and get back to enjoying life. The THD procedure offers a minimally invasive surgical approach to treating the source of the hemorrhoids. And, because there is in most cases no or little removal of tissue, there is minimal operative pain. In most cases, less than half the pain and difficulty with passing stool when compared to traditional cutting out surgery. THD (Transanal Hemorrhoidal Dearterialization) is offered as an out patient procedure which gets you back to normal activities quickly.

Clinical results in studies over 20 years have shown that patients who have THD may encounter less pain, less risk of complications, and faster return to activities in less than 2 weeks.

THD Technology


  • Vascular control of superior rectal arteries
  • Precise Doppler guided arterial ligation that addresses hyperflow
  • Rotational pivot guide provides safe, controlled, reproducible 6.5 mm depth
  • Elliptical scope geometry ensures close approximation of the SRA branches and enhanced Doppler sensitivity


  • Repositioning of the redundant/prolapsed tissue to its natural anatomical position
  • Sliding feature of the SLIDEONE Anoscope facilitates mucopexy under direct visualization, through a clear operating channel
  • Prolapse reduction and lift accomplished without excision of tissue
  • Mucopexy terminates between the anorectal junction and the dentate line

THD Procedure Benefits:

    • Quick outpatient procedure, about 45 minutes
    • Minimal post-op pain; patients are back to normal activities within 2 weeks
    • Minimally-invasive, no excision of tissue, limited risk of complications
    • Performed above the dentate line "no pain zone"
    • Doppler guidance, ensures artery location for ligation
