Colorectal Surgery

Colorectal surgery deals with the diseases and treatment of the anus, rectum and colon. Also known as proctology, colorectal surgical disorders are:

  • Haemorrhoids – inflammation of the veins in the anus and the rectum

  • Anal fissures – tears and unnatural cracks in the anus

  • Fistulas – abnormal connections between the anorectal area and the surface of the skin

  • Faecal incontinence

  • Rectal prolapse – the walls of the rectum protrude through the anus

  • Treatment for Crohn’s disease

  • Colorectal cancer

  • Anal cancer

  • Injuries to the anus

Diagnosis:

Diagnostic procedures include colonoscopy that tells the condition of the abnormality. It is an endoscopic examination of the distal small bowel with the help of a CCD or fibre optic camera. The tube is passed through the anus and provides a visual diagnosis of the polyps and ulceration. It helps in biopsies of polyps as small as 1 mm or less. The other diagnostic procedures are: sigmoidoscopy and proctoscopy.

Procedures:

  • Laparoscopic and open colectomy – Laparoscopic colectomy is a minimally invasive surgery where several small incisions are made into the abdomen. A video camera is passed through one of the incisions and the surgical tools from the others. The entire colon or part of the colon is resected with the surgical tools. Open colectomy requires incisions longer than those made in laparoscopic surgery. The colon is accessed and resected with the aid of surgical instruments.

  • Proctocolectomy with ileal pouch anal anastomosis – This procedure is predominantly performed to treat ulcerative colitis and familial polyposis. The large intestine is first removed followed by the rectum. The anal sphincter and anus are left untouched. About 1.5 feet of the small intestine is used to make a pouch and sewn to the anus. In case the procedure involves an ileostomy, it is closed at the end of the surgery.

  • Park’s procedure – Fourth-degree haemorrhoids are addressed with Park’s procedure. The diseased segment of the rectum is resected right up to the point where it is fixated. Primary coloanal anastomosis is done after the perianal mucosal stripping of the anorectal segment is accomplished.

  • Internal-lateral sphincterotomy – The procedure is performed to treat chronic anal fissures. The internal anal sphincter muscle is operated to lower the resting pressure and improve blood supply into the fissure. The procedure is extremely effective since it triggers faster healing processes. It is a subcutaneous technique involving an incision in the intersphincteric groove.
