Background |
There is limited epidemiologic data on sigmoid volvulus (SV) from non-endemic regions. Therefore, we performed a multicenter study to report contemporary outcomes and appraise literature-based methods that pair diagnostic and procedural codes to identify SV.
Method |
Using an automated search for patients with ‘volvulus’ in our system from 2011 to 2021, we reviewed electronic charts to clarify the diagnosis, automatically replicate three strategies to identify SV, and retrieved 6-month outcomes.
Results |
Of 895 patients, 109 had SV. Literature-based strategies poorly identified SV. At the index admission, patients underwent endoscopic reduction alone (33%), emergent (16.5%), semi-elective (34%), or elective (16.5%) surgery. Endoscopic reduction alone had high recurrence rates and delayed surgery was associated with worse outcomes.
Conclusion |
Literature-based strategies to identify SV suffer from misclassification bias which affects patient counseling. In this large series, one-third of patients do not undergo during their index admission despite improved outcomes with earlier surgery.

• | NSQIP strategies to identify sigmoid volvulus suffer from misclassification bias. |
• | Non-operative and palliative care are common management strategies. |
• | Earlier surgery during the index admission is associated with improved outcomes. |
• | Recurrence rates for sigmoid volvulus are high within the first 6-months. |
