Description

Mark Omundsen is a colorectal, laparoscopic and general surgeon providing surgical management of conditions including colon and rectal cancer, inflammatory bowel disease, rectal prolapse and defaecatory disorders such as incontinence and obstructive defaecation.

He is especially interested in minimally invasive approaches such as laparoscopic and single incision laparoscopic surgical techniques in the management of colorectal diseases, abdominal wall hernia and gallbladder pathology. He prefers to use these techniques where possible to reduce trauma to the abdominal wall and improve the patient’s recovery.
 

What is General Surgery?
The role of a general surgeon varies but in broad terms general surgery can be said to deal with a wide range of conditions within the abdomen, breast, neck, skin and, in many cases, vascular (blood vessel) system.
 
While the name would suggest that the focus of general surgery is to perform operations, often this is not the case. Many patients are referred to surgeons with conditions that do not need surgical procedures, but merely require counselling or medical treatment.
 
What is Colorectal Surgery?
The colon and the rectum are part of the digestive tract that processes the food we eat. Together they make up the large intestine or large bowel and are located in the abdomen between the small intestine and the anus. The colon is about 1.8m long and absorbs water and nutrients from food. The rectum is the last segment of the large intestine and is about 20 -25cm long. This is where waste material is stored before it passes out of the body through the anus.

A colorectal surgeon is a general surgeon who has had further training and specialises in the diagnosis and treatment of diseases of the colon, rectum, and anus.

What is Laparoscopic Surgery?
Laparoscopic (or keyhole) surgical procedures are performed through several small cuts (incisions) usually only 5-10mm long, rather than through one large incision.

A long, narrow surgical telescope (laparoscope) that has a tiny camera and light source attached, is inserted through one of the incisions so that the surgeon can view the inside of the body on a TV monitor.

The surgeon then passes specially designed surgical instruments through the other incisions and carries out the procedure using the TV monitor to guide the instruments.

Laparoscopic surgery is usually associated with less blood loss during surgery and less pain and scarring following surgery. In most cases, time spent in hospital is less and overall recovery time from the operation is less than with conventional open surgery.

Referral Expectations

When you come to your appointment, your surgeon will ask questions about your illness and examine you to try to determine or confirm the diagnosis. This process may also require a number of tests (e.g. blood tests, x-rays, scans etc). Sometimes this can all be done during one visit, but for some conditions this will take several follow-up appointments. Occasionally some tests are arranged even before your appointment to try to speed up the process.
 
Once a diagnosis has been made, your surgeon will discuss treatment with you. In some instances this will mean surgery, while other cases can be managed with medication and advice. If surgery is advised, the steps involved in the surgical process and the likely outcome are usually discussed with you at this time.
