They can be described as masses or clumps (“cushions”) of tissue within the anal canal that contain blood vessels and the surrounding, supporting tissue made up of muscle and elastic fibers. Although most people think hemorrhoids are abnormal, they are present in everyone. It is only when the hemorrhoidal cushions enlarge that hemorrhoids can cause problems and be considered abnormal or a disease.
If the hemorrhoid originates at the top (rectal side) of the anal canal, it is referred to as an internal hemorrhoid. If it originates at the lower end of the anal canal near the anus, it is referred to as an external hemorrhoid.
This is the newest technique for laser surgery for piles treating hemorrhoids, and it has rapidly become the treatment of choice for third-degree hemorrhoids.
This technique is much effective; easier approach and is done by only few surgeons in India including Dr.Rajan Modi at Kapadia Multispeciality Hospital.
