ABSTRACT
Background: The present study aims to find out age and gender prevalence of different anatomical positions ofappendix in acute appendicitis in a tertiary care hospital in chennai. Appendix may be placed in differentpositions, but the base of appendix is connected to the cecum. Based on the variations in the positions, appendixis classified into six types: retrocecal, pelvic, subcecal, paraileal, retroileal and subhepatic.Materials and methods: This study was done over a period of 1 year from June 2018 to June 2019 in 75 patients.Anatomical location of appendix was studied in acute appendicitis in different age groups and gender populations.Result: This study was conducted on 75 cases consisting of 40 (53%) males and 35(47%) females. Males weremore in number than females. Clinically diagnosed acute appendicitis cases were subjected to CT abdomen.Anatomical locations of the appendix were as follows: Retrocecal position was most commonly seen in 32individuals (43%), Pelvic in 25 individuals (33%), Subcecal in 10 individuals (13%), Postileal in 6 individuals(8%) and preileal in 2 individuals (3%). The incidence was more common in the age group of 31 to 40 years(33%).Conclusion: Retrocecal position is the most common location in our patients. CT is a good diagnostic indicatorfor acute appendicitis. As appendix is the most variable organ in the abdomen these findings are helpful forsurgeon to operate during appendicitis.
