What is CRH Banding?

CRH banding is a minimally invasive hemorrhoid treatment procedure where a small tight rubber band is placed around the internal hemorrhoid tissue, causing the tissue to shrivel up, fall off, and form a small scar. The result is relief of symptoms like bleeding and swelling.

How do I prepare for my CRH banding?

There are no special preparations needed for hemorrhoid banding, and normal activity is fine right after the treatment.

What to expect?

Generally when we offer hemorrhoid banding, it is done at the same time as a colonoscopy, at our GI facilities. There is no need for anesthesia, fasting or other preparation for the banding specifically, but if you are having a colonoscopy at the same time, you will be given detailed prep instructions to follow for that procedure. The banding may not be appropriate for all patients. You and our physicians will determine an appropriate treatment for your diagnosis.

 What can I expect after my CRH banding?

Following hemorrhoid banding, we recommend normal activity as tolerated, except for heavy lifting or vigorous exercise on the treatment day. You can resume full activity the next day. You can have normal bowel movements during this time, but you may want to soak in a sitz bath (a warm tub) or use a bidet for a gentler cleansing of the anal opening. Some sensation of pressure or a mild bowel urge is common for the day or so after each banding session; Pain is quite unusual but usually minor pain relievers are fine to take if needed. You’ll need to make some changes to prevent future problems, however. Straining due to constipation should be diligently avoided, so be sure to drink seven or eight glasses of water a day and add 15 grams of fiber to your diet (two tablespoons of natural oat or wheat bran). Metamucil, Citrocel, Benefiber, flax or other soluble fiber may be helpful as well. Your doctor will advise what seems best for the condition.

We also recommend that you not sit longer than necessary on the toilet. If you can’t have a bowel movement in that time, come back later. A “two-minute rule” can help keep you from straining during bowel movements without realizing it. Finally, when traveling, stay hydrated, avoid excessive alcohol, eat fiber and walk around when you can.

What are the risks involved with a CRH banding?

Side effects are rare but include:

• Severe pain that does not respond to the methods of pain relief used after this procedure. The bands may be too close to the area in the anal canal that contains pain sensors.
• Bleeding from the anus.
• Inability to pass urine (urinary retention).
• Infection in the anal area
