Mr Eriksen graduated MBChB in 1978 from University of Cape Town. After starting specialist surgical training in Durban, he took up a research post in Dundee, Scotland. In 1986, he was admitted as a Fellow of the Royal College of Surgeonsof Edinburgh. He completed his research in 1988, and graduated MD from University of Cape Town with the thesis "Duodenal pH: New aspects of physiology and pathophysiology". His specialist surgical training continued first at Ninewells Hospital, Dundee, then St Thomas' Hospital, London. He was appointed Consultant Surgeon in 1995 at Perth Royal Infirmary, Perth, Scotland.
He has very broad experience in all aspects of general surgery, from gall bladder surgery, small bowel surgery, large bowel surgery (colon and rectum), ano-rectal conditions, all hernia surgery (groin, incisional, and others) and varicose vein surgery.
His two areas of special interest are those of colorectal surgery and laparoscopic surgery.
In Colorectal Surgery, he has a special interest in cancer of the colon and rectum, and works in close collaboration with anaesthetic, radiological and oncological colleagues. The operations are performed either as open procedures or as laparoscopic (keyhole) operations.These patients are followed up very closely for the first five years post-operatively in accordance with his published protocol, and then less frequently thereafter. In addition to the colorectal cancer patients, he manages patients with inflammatory bowel disease (Crohn's Disease and Ulcerative Colitis), as well as a wide range of benign anorectal conditions.
In Laparoscopic Surgery (keyhole surgery), Mr Eriksen performs preferentially repairs of inguinal (groin) hernias by this method as well as all the abdominal wall hernias. The benefits to the patient in the form of less post-operative pain, less complications, a more cosmetic result, quicker return to normal activities and quicker return to work are all significantly better than with the open method of operation. Gall bladder surgery is also performed laparoscopically (laparoscopic cholecystectomy), as are selected large bowel operations.
