Prognostic factors in the decision-making process for sigmoid volvulus: results of a single-centre retrospective cohort study

Background Sigmoid volvulus is a common cause of emergency surgical admission. Those patients are often treated conservatively with a high rate of recurrence. We wondered if a more aggressive management might be indicated. Methods We have reviewed data of patients diagnosed with acute sigmoid volvulus over a 2-year period. The primary endpoint was patient survival. Results We analysed 332 admissions of 78 patients. 39.7% underwent resection. Survival was 54.9 +/- 8.8 months from the first hospitalization, irrespective of the treatment. Long-term survival was positively influenced by being female, having a low "social score", a younger age and surgery. Multivariate analysis showed that only being female and surgery were independently associated with better survival. Conclusion Early surgery may be the best approach in patients with recurrent sigmoid volvulus, as it ensures longer survival with a better quality of life, regardless of the patient's social and functional condition.
