title: In-hospital mortality and associated complications after bowel surgery in Victorian public hospitals.
abstract: BACKGROUND
  The purpose of the present paper was to determine the mortality rate and associated complications after large bowel resection and anastomosis in Victorian public hospitals.
  
  
  METHODS
  A retrospective analysis of data from the Victorian Inpatient Minimum Database (VIMD) was undertaken. The data were collected from all Victorian public hospitals performing hemicolectomy and anterior resection (resection of the rectum with anastomosis) from 1987/88 to 1995/96.
  
  
  RESULTS
  A total of 11036 patients underwent hemicolectomy or anterior resection in the time period studied, there being a 7% increase in the rate of operations performed over the 9 years. Two-thirds of these operations were for carcinoma of the large bowel. The anastomotic leak rate of 4.5% fell slightly but the in-hospital mortality rate of 6.5% did not change over the study period. The total morbidity recorded (mainly major complications) was 24.6%. The patients most at risk of death were the elderly with pre-existing cardiac or respiratory disease undergoing an emergency operation.
  
  
  CONCLUSIONS
  Notwithstanding some inaccuracies of coding and reporting, the morbidity and mortality for surgery of the large intestine remains high, largely due to the comorbidities of the patients, although certain technical complications such as leakage of an anastomosis after anterior resection are still associated with a significantly increased risk of death. Consideration should be given to the routine use of high-dependency nursing units for these high-risk patients after major colorectal surgery, and support from physicians to reduce morbidity and mortality from associated medical conditions worsened by surgery.
