FP2.11 - Management of Acute Sigmoid Volvulus – a 10-year retrospective review

Abstract Aims This study aims to review the management and outcomes of acute sigmoid volvulus within our Trust. Methods This was a retrospective study conducted at our NHS Trust. All adult patients presenting with SV between January 2012 and January 2022 were included. Data was collected from electronic patient records. Admission data included management (conservative only, CM, emergency surgery, ES, or planned surgery, PS), episode number, and 30-day mortality. Surgical data included ASA grade, complication rates, and bowel continuity rates. Results 219 patients (54.8% male, median age 72yrs) presented with acute SV. 87.2% patients were managed conservatively at index presentation, 44% of whom experienced recurrent SV. 27.4% patients received surgical management during follow-up (18.3% ES, 9.1% PS), none of whom experienced recurrence following surgery. The rate of ES increased linearly with total number of episodes, from 11% at index presentation to 25% at ≥5 episodes. 30-day mortality was 13.4% in the CM group, 15% in the ES group, and 0% in the PS group. Post-operative complication rate was 42.5% in the ES group and 5% in the PS group. Bowel continuity was achieved in 22.5% of ES patients and 60% of PS patients. Discussion Conservative management of SV was associated with a significant recurrence rate in our cohort. Repeat admissions were associated with an increasing incidence of ES, which was associated with worse outcomes compared with PS. We recommend all patients are considered for planned surgical intervention at index presentation to reduce recurrence and minimise the rate of emergency intervention.
