RIPASA versus Alvarado score in the assessment of suspected appendicitis in children: a prospective study

Authors

Abstract

Background
Diagnosis of acute appendicitis remains a problem in children with right lower quadrant pain.
Results
In this study, 158 of 179 patients were operated on. In 140 of the operated patients, the diagnosis of appendicitis was confirmed by histopathology. The negative appendectomy rate was 11.4%. Specificity and negative predictive value of RIPASA score were higher than those of Alvarado (<0.001). No difference was found between the two scores concerning sensitivity, positive predictive value, and the area under the receiver operator characteristics curve (>0.05).
Conclusion
The RIPASA scoring system can be used as an alternative to the Alvarado scoring system in the management of patients with right lower quadrant pain in emergency services and pediatric outpatient clinics. With the use of the RIPASA score, more patients with a low likelihood of appendicitis can be detected and further contributed to the reduction of the negative appendectomy rate.
