Haemorrhoids, Fissure, Fistula
Anal Fissure Surgery
An anal fissure is a small, painful tear or cut in the lining of the anus, usually caused by passing hard or large stools. When fissures become chronic (lasting longer than 6 to 8 weeks), surgical intervention may be required to help the area heal.
Lateral Internal Sphincterotomy (LIS):
The gold standard surgical treatment for chronic anal fissures. The surgeon makes a small incision in the internal anal sphincter muscle to reduce muscle spasm, improve blood flow, and allow the tear to heal properly.
Fissurectomy
In some cases, the surgeon may surgically excise the edges of the fissure to create a clean, fresh wound that can heal in a healthy environment.
Robotic Surgery
Similar to laparoscopic surgery, this highly advanced technique provides the surgeon with a 3D view and enhanced precision using robotic arms.
Anal Fistula Surgery
-
Fistulotomy
The most common and effective procedure, where the surgeon carefully cuts open the entire length of the fistula tract, flattens it out, and allows it to heal from the inside out into an open groove.
-
Seton Placement
For complex fistulas or those that pass deep through the anal sphincter muscles, a surgical thread (seton) is placed in the tract to drain infection and help the area heal, which protects the muscles from damage.
-
Sphincter-Preserving Techniques
Modern advanced procedures like LIFT (Ligation of the Intersphincteric Tract) or endoscopic closure allow surgeons to close the fistula tract securely while protecting the sphincter muscles and maintaining continence.
