ANATOMICAL VARIATIONS RELATED TO POSITION OF APPENDIX
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 46
Abstract
BACKGROUND Appendix may be placed in different positions, but the base of appendix is connected to the cecum. Based on the variations in the situations, appendix is classified into six positions: retrocecal, pelvic, subcecal, paraileal, retroileal and subhepatic. Aim- To study the variation in the anatomical features, length and external diameter of appendix and its association with age and sex in the Indian population. MATERIALS AND METHODS This descriptive study was conducted on a total of 418 cases, anatomical location of appendix was recorded, and length of vermiform appendix was measured with nylon thread from root to tip of appendix. Thread’s length was measured by vernier caliper. External diameter was measured by vernier caliper at the maximum external diameter of the appendix. RESULTS Around 418 subjects were included in the study, consisting of 251 (60.05) males and 167 (39.95) females. Clinically diagnosed acute appendicitis cases were subjected to thorough clinical examination, lab investigations, USG abdomen and appendiceal specimen was sent for histopathological examination after surgery. Anatomical locations of the appendix was as follows: Retrocecal in 111 individuals (55.5%), Pelvic in 47 individuals (23.5%), Retroileal in 18 individuals (9.0%), Subcecal in 13 individuals (6.5%), Paracecal in 10 individuals (5.0%) and Subhepatic in 1 individual (0.5%). A significant association was found between the appendix length and different age groups. The average length of appendix was 55 mm for men and 51 mm for women. The average external diameter of appendix was 73 mm for men and 65 mm for women. CONCLUSION Retrocecal appendix has symptoms of upper urinary tract infection due to irritation of the adjacent ureter. In pelvic position, pain may be felt when the thigh is flexed and medially rotated as the obturator internus is stretched. Pelvic appendix may irritate the bladder or rectum causing suprapubic pain, pain with urination or feeling of a need to defecate.
