ABSTRACT:

Background: The caecum acts as a guide in the operation of intestinal obstruction.  Vermiform appendix manifests wide range of anatomical and topographical variations. In appendicitis these variations cause different clinical presentations .A sound knowledge of normal anatomy and variations of caecum and appendix is very important to the operating surgeon.

Aim of the study: To study the morphometry of caecum and appendix  and ileocaecal orifice  in adult embalmed cadavers and correlate these  parameters with previous studies.

Materials and Methods: This study was conducted during routine cadaveric dissections performed in Department of anatomy, MVJ Medical college and research hospital, Bangalore. Twenty five cadavers were studied for the morphometry of  ceacum and appendix.

Results: Length of caecum ranged from 2.2 -7cm. Width of caecum ranged from 3-8.5cm. Majority of the caecum studied were of the adult type. As far as the position of appendix was concerned ,the pelvic type was most common. Length of appendix was ranged from3-9cm.Outer girth of appendix was ranged from0.5-1.1cm.Distance between appendicular orifice to lower end of caecum was ranged from0.3-5cm. Out of twenty five speceimens studied, in three specimens  appendicular orifice was completely obliterated. Diameter of appendicular orifice ranged from 0-0.7cm.Distance between appendicular orifice and ileocaecal orifice ranged from 1.5-5 cm. Diameter of Ileocaecal orifice ranged from 0.5-1.6cm.In twenty one specimens shape of the ileocaecal orifice was transversely oval. Two were longitudinally oval and one was triangular. Length of upper flap of ileocaecal valve ranged from1-2.2cm.Length of lower flap of ileocaecal valve ranged from 1.5-3.5cm.

Conclusion: Morphology of caecum and appendix was studied in detail. Above mentioned parameters of appendix  and caecum were comparable  with the findings of previous studies except the position of appendix where in pelvic type was the commonest type observed in our studies. In this study special emphasis was given to shape, diameter and measurements of the valves of ileocaecal orifice. These parameters have not been dealt with in previous studies.

KEY WORDS: Caecum, Vermiform appendix, anatomical variations.
