THD and Mucopexy for Hemorrhoids

Hemorrhoids are painful swollen veins that form in the anal canal.  Their location can be internal (upper part of the canal and covered by mucosa) or external (lower region around the anal opening and are covered by skin). Internal hemorrhoids can be treated by transanal hemorrhoidal dearterialization (THD) and mucopexy. In both procedures, no tissue is removed.

THD is a minimally invasive procedure performed under local, spinal or general anesthesia with a Doppler anoscope, a narrow tube inserted into the anal canal to locate arteries that supply blood to the hemorrhoids. Your surgeon stitches up six arteries to decrease the circulation of blood to the hemorrhoids. The suture forms scar tissue, which keeps the mucosal lining stuck to the wall of the anus. This limits the amount of blood feeding the hemorrhoid and keeps it suspended inside the anal canal.

Mucopexy is a surgical procedure, generally performed with THD. Your surgeon makes a suture around and through the length of the hemorrhoid. Both the ends (top and bottom) of the suture are tied together, pulling up and strangulating the hemorrhoid. The strangulated tissue dies and falls off, reducing the size of the hemorrhoid. The stitches form scar tissue, which helps the remaining hemorrhoid tissue to stay up in the anal canal.

As with all surgical procedures, THD and mucopexy may be associated with certain complications, which include pain, bleeding and recurrence.
