Abstract

Background: Small bowel volvulus is a rare entity in Western adults. Greater insight into epidemiology and outcomes may be gained from a national database inquiry.

Methods: The Nationwide Inpatient Sample (1998 to 2010), a 20% stratified sample of United States hospitals, was retrospectively reviewed for small bowel volvulus cases (International Classification of Diseases, 9th Edition [ICD-9] code 560.2 excluding gastric/colonic procedures) in patients greater than or equal to 18 years old.

Results: There were 2,065,599 hospitalizations for bowel obstruction (ICD-9 560.x). Of those, there were 20,680 (1.00%) small bowel volvulus cases; 169 were attributable to intestinal malrotation. Most cases presented emergently (89.24%) and operative management was employed more frequently than nonoperative (65.21% vs 34.79%, P < .0001). Predictors of mortality included age greater than 50 years, Charlson comorbidity index greater than or equal to 1, emergent admission, peritonitis, acute vascular insufficiency, coagulopathy, and nonoperative management (P < .0001).

Conclusion: As the first population-based epidemiological study of small bowel volvulus, our findings provide a robust representation of this rare cause of small bowel obstruction in American adults.
