WTP4.10 Utility of CT Imaging in a Successful Ambulatory Emergency Surgical Unit

Abstract Aim Drives towards ambulatory management in emergency surgery have resulted increased availability of urgent imaging to expedite decision making. This review CT usage aimed assess frequency surgical pathology identified, and subsequent management. Methods All acute general referrals an established clinic between 01/01/2021 22/07/2022 were included. Information regarding presentation, imaging, diagnosis collected prospectively maintained databases, subsequently analysed. Results 3154 patients seen over 18-month period with a 91.7% successful ambulation rate (n=2938). was performed 577 (18.2%); the majority contrast abdomen/pelvis (CTAP, 58.3%, n=331), or Kidney/Ureter/Bladder (CTKUB, 40.1%, n=228). The CTAPs diagnostic (77.0%, 242/331), 16.0% (n=53) resulting admission; admission for non-diagnostic 4.5% (n=4/89). Subsequent operations occurred 9.6% (32/331) who underwent CTAP; 5.1% (17/331) operation, 3.0% (10/331), 1.5% (5/331) listed electively. CTKUBs identified urological 40.4% (n=92), whilst 7.4% (n=17) other pathology. Diagnostic CTKUB led 17.5% (n=17, including 5 non-urological). Conclusion Selective scanning is useful adjunct diagnosis, avoidance. identify lower, but acceptable levels non-urological conditions. Judicious use important balance resource utilisation, limiting admissions.
