Negative Appendicectomy – Relevance of Scoring Systems – Alvarado, Modified Alvarado, Ripasa, Air and Nigam’s Scoring System (NSS)

Background and Aims: Acute appendicitis is an important and common problem world over. Complications of acute appendicitis are sometimes serious and even lethal. These complications can be presented by diagnosing appendicitis quickly and accurately allowing appendicectomy at earliest along with prevention of negative appendicectomy. Various scoring systems are in use to diagnose acute appendicitis. Nigam’s scoring system is compared here with other common scoring systems in relation to negative appendicectomy. The comparison of Nigam’s scoring system (NSS) and other scoring systems was done with our work on NSS and the work of other workers on other scoring systems. Methods: It is designed as a study of original study of scoring systems of acute appendicitis. Setting of this study was done in a primary care hospital with various specialties. 82 participants of this study attend emergency room and surgical OPDs with acute abdomen and referred to us on suspicious of acute appendicitis. Intervention was carried out as appendicectomy after thorough history taking, physical examinations and basic laboratory tests. Results: Showed high percentage of accuracy with zero incidence of negative appendicectomy. Conclusions: The comparative study of NSS with various other scoring system for diagnosing acute appendicitis shows that the rate of negative appendicectomy by using NSS is zero and no other scoring system compared here have shown this level.
