Patients with bowel cancer at Southampton's teaching hospitals have a 98.2% survival rate after surgery.
The national bowel cancer audit 2013 showed that a team of six surgeons at Southampton General Hospital performed 274 operations with one of the lowest adjusted mortality rates.
Part of the analysis was to judge each trust and gave them a percentage score, based on how ill the patients were, how high risk the procedure was and how many patients survived.
The national average was 3.1% deaths. University Hospital Southampton NHS Foundation Trust scored 1.8%.
James Smallwood, a consultant lower gastrointestinal surgeon said, "Achieving the best possible survival rate from major surgery is every surgeons ultimate goal."
