[Variations in position and place of formation of appendix vermiformis found in the course of open appendectomy].

This paper describes variations of the appendix vermiformis, found in the course of open appendectomy. Investigations involved surgeries performed in 2008 year in the Regional Hospital TeSanj. Variations in the site of formation and position of appendix vermiformis were established. Dominantly, appendix vermiformis is placed in the pelvic position in 57.71% of cases. In the smallest number of cases (2), or 3.07% lateral (paracecal) position was found. Variations of position of ostium appendicis vermiformis were registered as well. Two types of ostium appendicis vermiformis were found: dorso-medial wall of intestinum caecum below ostium ileocaecale (35.39%), dorso-lateral medial wall of intestinum caecum (30.7%) and lower pole of intestinum caecum (64.61%). Results of this research indicate very large variability of appendix vermiformis anatomy, which together with other factors (age, sex, phase in which is patient at the moment of examination) form a clinical picture of the acute appendicitis.
