Abstract
- PURPOSE
One of the most challenging groups of patients to diagnose that visit an emergency department (ED) is the female with acute abdominal pain. The causes of acute abdominal pain range from minor, self-limiting conditions to life-threatening disorders. Differential diagnosis for these patients is extensive and frequently requires multiple examinations and tests. This study analyzed the effectiveness of surgical abdomen detection using various physical examination and clinical laboratory methods, for young women reporting non-traumatic abdominal pain.
METHODS
This study reviewed computed tomography (CT) reports for 232 women, aged 21~35 years old, who visited our ED for nontraumatic abdominal pain from July 2009 to June 2010. Bivariate analyses relating physical and laboratory methods used to detect surgical abdomen were conducted. A multivariate logistic regression model was then derived, with all variables in the final model significant at p<0.05.
RESULTS
The number of patients who required surgical intervention was 88, while the number who did not require surgery was 144. Significant predictive methods for identifying surgical abdomen were maximal tenderness site (p=0.019), rebound tenderness (p=0.037), white blood cell count (p=0.012) and urine blood (p=0.037). The bootstrap result was identical in 1000 samples with a 95% confidence interval.
CONCLUSION
Maximal tenderness site, rebound tenderness, and results indicating leukocytosis and hematuria were found to be independently valid factors for detection of surgical abdomen in young women evaluated in our ED due for nontraumatic abdominal pain.
