Professor Andrew Hill has established an internationally recognised research group in surgical peri-operative care (before, during and after surgery) and has made leading contributions to understanding the metabolic response to surgery. He is internationally renowned for his surgical specialty of colorectal surgery and gastrointestinal diseases. His innovative “two-wound hypothesis” has shown that in abdominal surgery, two wounds are made and both influence postoperative recovery and provide separate therapeutic targets. This has led to the use of intraperitoneal local anaesthetic (IPLA) which improves outcomes for patients after major surgery. His work with IPLA and preoperative steroids has now been incorporated into international surgical guidelines. Andrew has carried out more randomised trials than any other surgeon in New Zealand, through which he has made major discoveries on colectomy, abdominal surgery and postoperative recovery. He is the immediate past president of the International Society of Surgeons (ISS), where he worked to expand its reach and influence. He is currently leading the G4 global alliance taskforce, seeking to establish minimum standards for surgical care internationally, which is helping to optimise outcomes in resource-poor communities
