Abstract :

 Background Appendicitis is a common problem in Indian scenario speci􀃶cally I children upto 14 years. Often they

present in the OPDs as pain abdomen with or without vomiting and fever. Generally in most health centers either
primary, secondary or tertiary the investigation of choice is Ultrasonography. Though the investigation is fairly capable of detecting
Appendicitis or an in􀃸amed appendix in majority there are enough instances where it fails to pick up the in􀃸amed appendix. Keeping this
gap in mind we in the radiology department decided to track coming pediatric population with suspected appendicitis for determining the
efficacy of Ultrasonography for diagnosing Appendicitis
Methodology the present cross sectional observational study was done over a period of six months starting from Jan 2017 to June 2017 in
the radiology department. A total of 128 cases were included. All suspected cases for appendicitis were included after consent from the
parents. Cases who were not willing to participate and who were not admitted were excluded from the study. Once the USG was done
patients, were tracked for the 􀃶nal outcome be it Surgery /Discharge or clinical con􀃶rmation based on the Discharge ticket. Axial Diameters
largest >6mm on USG were considered to be diagnosed as Appendicitis .The 􀃶ndings thus found were compared with surgical and
pathological 􀃶ndings and in cases where there was no surgery Discharge diagnoses was taken as the 􀃶nal diagnosis.
Results Appendix was identi􀃶ed in 65% (83)/128 of suspected cases . The overall sensitivity was 88.89% ( 95% CI 65.29% to 98.62)
,speci􀃶city 89.23 % (95% CI 79.06% to 95.56%) , Positive Predictive Value 69.57% ( 95% CI 52.70% to 82.42% ) , negative predictive value
96.67 % ( 95% CI 88.67% to 99.08%) accuracy 89.16% ( 95% CI 80.41% to 94.92%) .
Conclusion With a fairly high accuracy Ultrasonography is choice of imaging for pediatric population presenting with suspected
appendicitis and can help in preventing the morbidity due to appendicitis in children.
