On the relationship between body dimensions and appendix length

摘要

In the last decades a lot of significant correlations between clinical and anthropometric parameters were found, e.g. the relationships between somatotypical and endocrine parameters or between body dimensions and echocardiographic heart size. During operation, surgeons often find a wide range of appendix size of patients with varying body dimensions. A goal of this work is the detection of the relationships between anthropometric characteristics (height, weight, body mass index (= BMI)), inflammation parameters (histological inflammation degree, leukocyte count and C-reactive protein (= CRP)) and the appendix length with n = 167 consecutive patients (time period 1.1.2004 - 31.12.2006; range of age 7 - 95 years, median age 20 years; average age of men 27.7, women 26.6 years), which had to be operated because of acute appendicitis. Appendectomy was laparoscopic in 95 % of the patients and open in 5 %. The appendix length of the male patients was high-significantly longer with a mean of 7.5 cm (SD = 2.1) than those of the female patients with 6.3 cm (SD = 1.6). The following mean anthropometric values were registered: height 169.8 (SD = 15.6) cm for the males and 165.2 (SD = 9.6) cm for the females, weight 70.4 (SD - 23.4) kg for the males and 61.9 (SD = 16. 1) kg for the females, BMI 24.1 (SD = 5.4) kg/m(2) for the males and 22.9 (SD = 4.8) kg/m(2) for the females. The mean leukocyte count was 12,700 (SD = 5,500)/ ml for the males and 11,600 (SD = 4,900)/ml for the females, CRP was 4.3 (SD = 5.4) mg/l for the males and 4.5 (SD = 8.9) mg/l for the females. Concerning the histopathological diagnosis, n = 76 patients (45.5 %) suffered from a submucous fibrosis / obliteration, n = 21 (12.6 %) from an acute purulent inflammation degree, n = 65 (38.9 %) from an ulcerative / phlegmonous inflammation degree and n = 5 (3 %) from a perforation. While no significant Spearman's correlation coefficient between appendix length and CRP was found, the appendix length correlated highly significantly to the body weight (r = 0.25) and significantly to leukocyte count (r = 0.16), body height (r = 0.16), BMI (r = 0.17) and the histological inflammation degree (r = 0. 18). Thus, the correlations found were lower than the relationships between anthropometric and endocrine or echocardiographic parameters described in literature.
