The Role of a Colorectal Surgeon

Colorectal surgeons are medical professionals specializing in the management of diseases of the gastrointestinal tract, which consists of the colon and the rectum. These areas can be affected by several conditions, such as colon and rectal cancer, diverticular disease, inflammatory bowel disease, and anorectal conditions. To treat these issues, colorectal surgeons perform a variety of surgical procedures. For example, based on the needs of the patient, they may perform laparoscopy, which is less invasive; or an open surgery with relatively larger incisions; or more complex surgeries, such as colectomy, proctectomy, and ileostomy. The function of the colon and rectum is to extract water and salt from indigestible material, breaking it down into smaller parts for elimination. By such surgical procedures, colorectal surgeons can help to alleviate the painful and uncomfortable symptoms of colorectal diseases and help people to enjoy a better quality of life.

Common Colorectal Conditions

Among the common colorectal conditions treated are:
  • Colon cancer
  • Rectal cancer
  • Anal cancer
  • Haemorrhoids
  • Diverticulitis
  • Irritable Bowel Disease (IBD)
  • Bowel obstruction
  • Faecal incontinence and constipation

Types of Colorectal Surgery for Colorectal Cancer:

> Open surgery

The surgery is usually done through a single long incision to access the abdomen.

> Laparoscopic surgery (minimally invasive)

The surgery is done through several smaller incisions to insert surgical instruments into the abdominal cavity. A laparoscope is a long, thin lighted tube with a small camera on the end which transmits images from the abdominal cavity to a high-resolution video monitor in the operating room. For surgeries that involve colorectal cancers, the type of surgery used would depend on how big the tumour is and the stage of the cancer, whether it is an emergency, and the general health condition of the patient at the time. Our colorectal surgery division provides advanced, multidisciplinary, and end-to-end care and treatment for colon, rectal, and anal conditions.
