Dr Luke Traeger is a South Australian General Surgical trainee with the Royal Australasian College of Surgeons. Luke is currently undertaking a PhD, researching the effects of novel treatments to reduce bowel paralysis following surgery.

My research investigates the reduction of the incidence and duration of post-operative ileus following colorectal surgery.

After abdominal surgery, the bowel can commonly be paralyzed and slow to return to normal function. The resultant intolerance to food and liquids can result in severe bloating, inability to pass a bowel movement or gas, nausea, and vomiting. This complication of surgery is called post-operative ileus and is a source of discomfort for patients after surgery. Management often requires invasive procedures such as the insertion of long tubes into the stomach to empty it out and providing nutrition through a vein. 

With the advent of enhanced recovery protocols, there has been a general improvement in the management of patients undergoing abdominal surgery. However, the incidence of post-operative ileus remains around 20-30%. Post-operative ileus doubles the cost of a patients admission to hospital and significantly increases the patients risk of complication and risk of mortality.

My research will investigate the use of a novel treatment, an acetylcholinesterase inhibitor named pyridostigmine. Pyridostigmine increases gut motility, and we aim to study the effects this has following colorectal surgery. If we can reduce the incidence of post-operative ileus, this may reduce the length of hospital stay and reduce complications in our patients.
