Sclerotherapy

Hemorrhoid sclerotherapy in Montreal, chosen deliberately

An injection rather than a band or an applicator, and one that suits small internal hemorrhoids in particular. It is not a weaker version of the others, but it does carry a trade-off worth hearing before you agree to it.

The injection

An injection, and what it suits

Sclerotherapy works by injection rather than by placing a band or applying energy to the tissue. It sits in the same group of office-based options as the other two, done in a clinic room without a general anaesthetic, and it is the one most specifically matched to small internal hemorrhoids.

That specificity is really the point of it. It is not the option to reach for when something larger needs treating, and it is not a lesser version of banding either. It is a different tool with a narrower range, and the examination is what identifies that range.

So being offered this should come with a reason specific to what was found. If it is presented as simply the gentler choice, that is worth questioning on the spot. Infrared coagulation and the grading both cover where it sits.

The appointment

Your Montreal sclerotherapy visit, in order

  1. Sizing it up

    The examination establishes whether what is there is in the range this procedure is actually suited to.

  2. The reason, out loud

    If this is being recommended over the alternatives, the reason should be specific to your findings.

  3. The injection

    Done through an anoscope in a clinic room, in minutes, with no general anaesthetic involved.

  4. Honest follow-up

    Reviewed properly, because recurrence after this one can be higher and pretending otherwise helps nobody.

The trade-off

The recurrence figure nobody mentions

One published review notes that complication and recurrence rates after sclerotherapy can be high. That is not a reason to rule it out, and it is not a figure we will dress up as a percentage, but it is the kind of thing that should be said before a procedure rather than after.

In practice it means this option gets chosen for a reason rather than by default, and that follow-up matters rather more here than it does elsewhere. A clinic recommending it as the easy choice without mentioning any of that is not giving you the whole picture.

If recurrence is your main worry, why they come back is the honest version of that, in office against surgery covers the point at which durability starts outweighing convenience, and the evidence guide covers where the sources disagree.

Common questions

Sclerotherapy questions in Montreal

What people ask when an injection has been suggested instead of a band, and why that might be.

It is different rather than weaker. It suits small internal hemorrhoids specifically, and one review notes that complication and recurrence rates after it can be higher, which is why it is chosen deliberately.
There should be a reason specific to your examination, usually the size of what was found. If it has been presented simply as the gentler option, that is worth asking about directly.
It is done without a general anaesthetic, in a clinic room, in minutes. People describe pressure rather than sharp pain, and what they notice afterwards varies between individuals more than between procedures.
One review says recurrence can be high, and we will not convert that into a percentage, because the published figures for these procedures vary enough that a single number would be invented.
Often yes, if your grade and the size of what is there suit it. That is a reasonable question to put to whoever is recommending the injection, and you should get a specific answer.
Possibly, for the same reason as the other office procedures: more than one column is often involved. The number comes from the examination rather than from a figure here.

Why the trade-off is on this page

A narrow fit

It suits small internal hemorrhoids specifically, which is a narrower claim than being a general-purpose option.

Recurrence named

One review reports that recurrence after it can be high. Saying so before the procedure is the point.

No percentage given

We will not convert a published range into a single figure, because that would be invented rather than measured.

Follow-up matters more

Because of the recurrence picture, the review appointment carries more weight here than elsewhere.

See whether Montreal sclerotherapy fits

This one is matched to a narrow range, so whether it suits you is a question the examination answers. If something else fits better, that is what we will recommend.

If another office procedure would hold better for your grade, you will hear that instead.
