BACKGROUND The aim of the study is to study the- 1. Correlation between sonological and histopathological diagnosis of acute appendicitis. 2. Prevalence of acute appendicitis in various age groups. MATERIALS AND METHODS The study was conducted in the Department of Radiodiagnosis, MVJ Medical College and Research Hospital, Bangalore, for a period of 2 years from March 2013 to February 2015. Data collection was prospective. A computer-assisted search of all the reports of ultrasonography with the diagnosis of acute appendicitis was conducted within the departmental database. A total of 244 patients (128 male patients and 116 female patients) with acute appendicitis were identified and the study was conducted. RESULTS In the study, total of 244 patients were diagnosed with acute appendicitis. Out of these, 128 patients were males and 116 patients were females. The incidence of acute appendicitis was most prevalent in age group between 21 to 30 years (36.5%) in our study. The least incidence was noted in age group of above 60 yrs. with only 1 out of 244 patients (0.4%) was diagnosed with acute appendicitis. The histological features noted were suppuration/inflammation, gangrenous, lymphoid hyperplasia and perforation. In our study, 143 inflammation/suppuration (58.6%), 37 gangrenous (15.1%), 24 lymphoid hyperplastic (9.8%) and 1 perforation (0.4%) was noted. Hence, the incidence of inflammation/suppuration was found to be most common and perforation was found to be the least finding. The suppurative/inflammatory feature was most common histological type in all the age groups except for the age group above 60 yrs. The gangrenous features were most commonly seen in the age group between 11 to 20 yrs. followed by 20 to 30 yrs. Faecolith was most commonly found in age group of 21 to 30 yrs. (12 cases) followed by age group of 11 to 20 yrs. (10 cases). CONCLUSION It was noted that the incidence of acute appendicitis was most commonly noted in younger age group and its incidence decreases as the age advances. The most cases revealed suppuration/inflammation and perforation was noted to be of the least histological variant.
