Advanced

Improved diagnostic accuracy in patients with suspected appendicitis

Tingstedt, Bobby LU and Andersson, Roland LU (2005) In Annals of Gastroenterology 18(1). p.65-69
Abstract
Background: Studies during the 1990s showed that it was

possible to reduce the rate of negative appendectomies by using various diagnostic methods. The present study aims to evaluate the effect on diagnostic accuracy of implementation of repeated clinical examination and blood tests in a small county hospital without possibilities of radiological assistance on a 24-hour basis.

Methodology: Prospective study of all appendectomies performed at Ystad General Hospital, Sweden. Leukocyte count and C-reactive protein levels were analysed in all patients. Patients with suspicion of acute appendicitis were admitted for active observation, repeated clinical examination and analyses of leukocyte counts and CRP levels.

Methodology: Prospective study of all appendectomies performed at Ystad General Hospital, Sweden. Leukocyte count and C-reactive protein levels were analysed in all patients. Patients with suspicion of acute appendicitis were admitted for active observation, repeated clinical examination and analyses of leukocyte counts and CRP levels.

Results: 533 appendectomies were performed during 1996-

2000 and compared with the index year 1995. Diagnostic

accuracy increased from 73% to 90% (p<0.01). The rates

of perforations and complications did not change during

the study period, being 12.4% and 5.1%, respectively. Coinciding with the increased accuracy, a drop in the number of appendectomies performed and a longer time interval from admittance to the start of operation was seen.

Conclusion: Through repeated clinical examinations and

blood tests it was prospectively possible to achieve an increase in diagnostic accuracy in patients with suspicion of acute appendicitis without any noticeable side effects. (Less)
