Q What is DHAL [Doppler Hemorrhoidal Arterial Ligation]?   


Doppler Hemorrhoidal Arterial Ligation (H.A.L.) is performed using a modified proctoscope in conjunction with a Doppler ultrasound flow meter. A needle and thread is passed beneath the artery, and a knot is externally tied, to stop the blood flow to the hemorrhoid.
