Dr Andrew McCombie works in the Department of Surgery on various projects in inflammatory bowel disease and bowel cancer.

Andrew has recently completed a long term follow up of ileal pouch surgeries performed in Canterbury in the past two decades from which two papers were published.

He and Associate Professor Tim Eglinton are presently translating the information from this study into a patient information brochure for ulcerative colitis patients considering ileal pouch surgery; this is expected to be available for public consumption by the end of 2016.

Andrew is also presently working on studies about quality of life (10Ten Study) and mindfulness (CALM Study) in the domain of bowel cancer.

Outside the Department of Surgery, Andrew is also involved in other projects including in questionnaire validation, patient education resources, and smartphone app development.

In 2014 Andrew completed his PhD in the psychological aspects of inflammatory bowel disease.
