Small haemorrhoids can be banded during a colonoscopy procedure(Generally most gastroenterologists  do not band the haemorrhoids but refer that on to the surgeons)

The benefits of banding compared to surgery to excise the haemorrhoids are that: 1. It is relatively painless(if the rubber bands are placed high above the anal canal) 2. It does not require any more anaesthesia than the one for the colonoscopy.

It is a relatively quick procedure to perform. A short proctoscope is inserted. The rubber band is loaded onto the suction bander. The haemorrhoids is sucked up onto the suction head and the rubber band is then applied. This rubber band strangulates the neck of the haemorrhoid. This is then repeated on the other haemorrhoids seen.

Complications are uncommon. Sometimes they may be discomfort or feeling or an urge to go to the toilet after the procedure. Occassionally, if the haemorrhoids is large, it can be painful. Bleeding and blood clots may be notice when the haemorrhoids sloughs off over the next 2 weeks.(If there is severe bleeding one should see a doctor immediately – patients on blood thinners and with liver problems are at higher risk of bleeding)
