Anatomical Variations in Position of Vermiform Appendix an Anatomical Study of Aborted Fetuses
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 1
Abstract
Background: The appendix is a vestigial organ, narrow tube-like structure lying in the right iliac fossa. It is part of the large intestine, and its base is attached to the posterolateral surface of the caecum just below ileocecal junction, the tip is free, and it may be present in retrocecal, subcecal, pre/post ileal, or pelvic positions. Knowing the exact anatomical position of vermiform appendix is important in view of surgeons for on time diagnosis and management of acute appendicitis. Aim of the Study: The aim of the study was to determine the different characteristics of vermiform appendix in aborted fetuses. Materials and Methods: A total of 138 aborted fetuses were subjected to dissection to identify the position of the vermiform appendix. Other parameters noted were the length of the appendix, formation of mesoappendix, and direction of the tip of the vermiform appendix. Observations and Results: Among the 138 fetuses included in the study 89 (64.49%) were male and 49 were female fetuses (35.50%). Observing the position of the appendix, it was noted that among the male fetuses the pelvic position was seen in 52 fetuses (58.42%) followed by subcecal in 14 (15.73%), retroileal in 12 (13.48%), retrocecal in 4 (04.49%), ectopic in 4 (04.49%), and pre-ileal in 3 (03.37%). The tip of the appendix was at 2’ O clock position, being the most common in 59 (%) of the male fetuses. The mean length of the appendix in fetuses between 11 and 20 weeks was 14.98 mm, in fetuses between 21 and 30 weeks was 23.65 mm, and in foetuses of 31 to –40 weeks was 35.24 mm. Mesopappendix was completely formed in 79.5% of the bodies. Conclusions: There was no clear-cut association between the sex of the festuses and the position of the appendix. Anterior anatomical position was the most common position for vermiform appendix which was not correlating with other reports from western countries. Most probably factors such as race, geographical location, and dietary habits play some role in determining the position of the vermiform appendix.
