| Popis: | The aim of this study is to analyze the increasing need of radiological support in the diagnosis of acute appendicitis (AA), the clinical repercussions associated, and the parameters of diagnostic accuracy of ultrasound and computed tomography (CT) scan for AA.Observational and analytical study. Cohort, patients operated on for suspected AA at a tertiary referral hospital. Pregnancy and14 years were exclusion criteria.January 2010-December 2011 (n1=419).set of patients aged 18 to 65 years old operated between October 2001-September 2003 (n2=237). Variables analyzed in both groups: 1) percentage of radiological support for diagnosis of acute appendicitis; 2) sensitivity and positive predictive value (PPV) of ultrasound and CT scan; 3) rate of surgical explorations with negative result or with diagnosis other than acute appendicitis.SPSS software, χ(2) test, statistical significance accepted with P.05, 95% confidence interval (95% CI) for the odds ratio (OR).Age, gender, percentage of atypical locations and gangrenous/perforated episodes were similar in both groups. The number of radiological examinations needed for diagnosis was significantly higher in the study group (78.8% vs. 30.4%, P.0,000). Sensitivity was significantly superior for CT than for ultrasound scan (97% vs. 86%), but PPV was similar in both tests (92% vs. 94%). Surgical exploration percent values with diagnosis of acute appendicitis was significantly higher in the study group (94.5% vs. 88.6%; P.006, OR 2.2; CI 95% 1.25-4).CT and ultrasound scan are excellent diagnostic tools for acute appendicitis, and have contributed to a significant increase in surgical explorations with correct diagnosis. |
