Expert Perianal Surgery in Darwin for Hemorrhoids and Abscess Drainage
Perianal Surgery is a broad term covering many different conditions of the anal/rectal region that may require surgery including but not limited to:
Haemorrhoidectomy
When haemorrhoids are extensive, prolapsing or very painful, they may require removal by surgery. This is done under anaesthesia by removing a small amount of skin and inner lining of the anus and the piles tissue which consists of the swollen blood vessels.
Abscess Drainage
A perirectal abscess is a collection of pus located in the deep tissues surrounding the anus. In most cases the abscess needs immediate attention to prevent the condition worsening. For drainage of abscess, the skin is cut open to allow any discharge left inside to drain out.


Expert Fissure and Fistula Surgery in Darwin by Dr. Maran
Fissures
An anal fissure is a tear in the skin inside the anal canal. This may cause pain with each bowel movement and passing of blood. The anal sphincter often goes into spasm and worsens the pain. This often require non-surgical management in most cases. However, surgical intervention will be necessary if conservative measures fail. Sphincterotomy surgery allows a fissure to heal. A small part of the anal sphincter muscle is cut to open the anal canal. This relieves pressure when you move your bowels and allows a fissure to heal.
Fistula
Certain type of abscesses may result in a tunnel from the anus to the skin. This is a fistula. A fistula can cause pain, discharge and recurrent abscess. Careful surgical intervention is necessary to avoid incontinence. Fistulotomy/Fistulectomy is surgery for Fistula.
