Abstract

AIM: Acute appendicitis should be diagnosed accurately and precisely, so that appendectomy is neither at the cost of morbidity nor at the cost of a normal appendix. PATIENTS AND METHODS: - The prospective validation of scoring system was conducted in the department of surgery, IGGMC, Nagpur. During the period from May 2002 to Jan 2012 total 683 patients with preoperative diagnosis of acute appendicitis were included in the study. We have developed a scoring system by using bedside six parameters and their scores which were proved to be significant in accurate diagnosis of acute appendicitis. RESULTS:-The number of histopathologically proved acute appendicitis patients in our study is 596. Out of these, 18 patients had perforated appendix. The overall incidence of incorrect diagnosis of acute appendicitis was 12.74%. Positive predictive value is 70.06 %. CONCLUSION:-The devised scoring system help to reduce the negative appendectomy rate and it can be good assistance in suspected cases of acute appendicitis for making an accurate diagnosis. If the present scoring system is followed the negative appendicectomy rate would be 4.69 %. However, further randomized control trial is needed to investigate the clinical benefit of practical scoring in acute appendicitis.
