“…Ultrasonographic appearances of acute appendicitis were initially described by Pearson [1] as that of a non-compressible, aperistaltic tubular structure with a central dilated lumen, surrounded by an inner echogenic mucosal layer and an outer, edematous wall that shows few echoes. The criteria of AP diameter and wall thickness were suggested by R. Brooke Jeffery Jr [2,3] and his fi ndings were confi rmed by David H. Adams et al [4] and Ooms and Associates [5].…”

Context Acute appendicitis poses a signifi cant diagnostic challenge to the surgeon. Despite modern advances, the diagnosis of appendicitis remains essentially clinical. Ultrasonography is effective in supplementing the clinical diagnosis.Aims This study aims to evaluate the negative appendicectomy rate in patients subjected to appendicectomy and to assess the usefulness of ultrasound in improving the diagnostic accuracy. Settings and DesignIt is a retrospective review of prospectively collected data on 118 patients operated for suspected acute appendicitis in a single surgical unit between May 2001 and December 2002. Methods and MaterialThe detailed history, clinical examination and preoperative investigations according to protocol were recorded on a proforma. All patients underwent an ultrasonography of whole abdomen including pelvis. Each patient with suspected acute appendicitis was subjected to surgery and appendix was submitted for histopathological examination. The negative rate of appendicectomy, sensitivity and specifi city of ultrasonography and positive and negative predictive value of ultrasound were calculated.Results The negative appendicectomy rate was 23.72%. In males it was 13.43% and in females 37.25%. Ultrasonography had a sensitivity of 63.33 % and a specifi city of 82.14 %. The predictive value of a positive test was 91.93% and the predictive value of a negative test was 41.07%. ConclusionsThe clinical diagnosis of acute appendicitis when supplemented with an ultrasonography, can achieve a reasonable degree of diagnostic accuracy with resultant low negative exploration rates thereby reducing the fi nancial burden and morbidity by avoiding unnecessary appendicectomy and keeping the cost of treatment affordable.Keywords Appendicectomy . Ultrasonography . Negative Rate Key Messages• Despite modern advances in imaging and technology, one can still reliably diagnose acute appendicitis clinically.• It is important to have low negative appendicectomy rates in order to minimize the fi nancial burden and the attendant increased morbidity and late complications like adhesive intestinal obstruction following unnecessary appendicectomy.
