Transanal hemorrhoidal dearterialisation, which is the second of the two named alternatives to a conventional operation for internal hemorrhoids. The long name is doing useful work, so it is worth unpacking rather than skipping.
Take the term apart and it tells you most of the idea behind it. Transanal describes the route in. Hemorrhoidal says what is being treated. Dearterialisation says the arterial supply is what gets addressed, rather than the tissue being cut away or fixed back into position with staples.
Which makes it conceptually closer to banding than to removal, in the sense that both of them work on the supply rather than by excision, while this one is still a surgical procedure rather than an office procedure. It is named for internal hemorrhoids specifically, not for external disease.
Beyond what the published term itself supports, this page stops. Stapling is the other named alternative, and conventional removal is what both of them are alternatives to, including for the large external disease where neither of them applies at all.

How it comes up
When THD is raised in Montreal
Internal and surgical
Like stapling, it only arises once internal disease has moved past what an office procedure can hold.
All three named
Conventional removal, stapling and dearterialisation. Hearing only one of the three is a reason to ask why.
The mechanism explained
If this is recommended, you should hear why the arterial approach suits what was found in your examination.
Detail from the surgeon
Operative specifics and recovery belong in that conversation, with your written questions in hand.
Judging a recommendation
How to weigh an option you cannot research
There is a practical problem with a procedure like this one. The material a patient can actually reach about it is thin, and most of what a provider publishes is marketing. So the usual advice to go away and read up before deciding does not get you very far here.
What does work is moving the question off the procedure and onto the recommendation. Why this one, for what my examination specifically found. What happens if it does not hold. What the alternatives were, and the reason each was set aside. Three answers, and they tell you more than any brochure.
A clinician who answers all three in terms of your own findings is giving you something you can actually judge. One who answers in generalities is not. Choosing a clinic covers that test, what the evidence says covers the sourcing, and the office comparison covers whether you need surgery at all.

The alternatives
What THD sits beside in Montreal
The two routes this is an alternative to, and the reading that prepares you for a surgical appointment.
What people ask about the option with the longest name and the least written about it.
Transanal hemorrhoidal dearterialisation. Transanal is the route in, hemorrhoidal is what is treated, and dearterialisation means the arterial supply is what gets addressed rather than the tissue removed.
Conceptually both work on the supply rather than by excision, but banding is an office procedure done in minutes in a clinic room, and this is a surgical one. The setting is the practical difference.
The research behind this site did not source a comparison between them, so we are not going to assert one. Both are named as alternatives for internal disease, which is all that is supported.
Because the sources named the procedure without giving us its outcomes or recovery. Writing those from guesswork would make the page longer and less trustworthy at the same time.
No. Like stapling, it is named for internal hemorrhoids only. Large external disease sits under skin, and that is the territory where conventional removal is the route that actually applies.
Why the arterial approach suits what your examination found, what the recovery involves, and what the plan is if it does not hold. Take those three in written down.
THD
Why the gap is left visible
The term does the work
Dearterialisation points at the arterial supply. That reading of the published name is what this page rests on.
Internal only
Named for internal hemorrhoids. Large external disease goes to conventional removal instead.
Nothing invented
No recovery time and no outcome figure, because none was sourced. The gap is recorded rather than filled.
Questions instead
What the page cannot answer, it turns into three things worth asking at the surgical appointment.
None of the surgical routes matters until the examination shows an office procedure will not hold for your grade. That is the question to settle first.
