OBJECTIVES: Recent reports indicate that early CT scan (within 24 h) increases diagnostic accuracy, reduces hospital stay and mortality in patients with an acute abdomen. The aim of this study was to assess the surgeons' use of CT in patients with an acute abdomen and the impact of this on diagnostic accuracy and mortality. PATIENTS AND METHODS: Patients older than 25 years admitted as an emergency with acute abdominal pain were prospectively evaluated. RESULTS: Two hundred and eleven patients fulfilled the inclusion criteria including 129 women and 82 men with a mean age of 62.4 years (range 27-92 years). The correct diagnosis on admission was made in 99 (47%) patients. CT was performed in 81 (38%), including 24 who had the scan performed within 24 h of admission. The sensitivity, specificity and accuracy of CT were 86%, 79% and 84%. CT was considered to have changed clinical management in 40 patients. Fifteen patients died, and one death may have been prevented by an early CT. Five had a delay in diagnosis of a serious condition; all could have been prevented by early CT. CONCLUSION: Selective use of CT increases diagnostic accuracy and improves the management of patients with an acute abdomen. Clinical trials are necessary to assess outcome following selective vs routine use of CT in this group of patients.
