The anatomy of the vermiform appendix shows variations in its macroscopic dimensions some of which have potential to influence the clinical aspects of the appendix. Anatomical studies on the appendix using people in Bangladesh as a sample are limited and fall short of producing any standardized anthropometric data. This study is predominantly a cross-sectional observational study which also uses some statistical analysis to understand the relationships amongst variables.
Fifty-six adult male postmortem appendices and adnexa were examined for macroscopic features. Possible interrelationships among the variables were assessed through statistical analysis. The age of the samples ranged from 18 to 67 years. The most common position of the appendix was retrocolic (53.57%) followed by pelvic (30.35%), postileal (12.5%), and subcaecal (3.5%).
In most cases (62.5%) the mesoappendix did not reach the tip of the appendix. The appendicular length varied from 6.00 cm to 16.30 cm with mean (± SD) and median value of 10.21 ±2.50 cm and 10.00 cm respectively. The base of the appendix was 1.90 to 3.80 cm away from the ileocaecal junction. The other macroscopic measurements of the appendix were taken at the base, at the midzone and at the tip of the appendix and the mean of the three measurements was considered as the overall value. Thus, the overall external diameter varied between 0.32 cm and 0.83 cm. Assessment of possible correlations amongst different variables revealed a significant negative correlation between the age of the subjects and the length of the appendix.
The data of the present study may provide a baseline along with some previous data in the standardization of the anthropometric information regarding the vermiform appendix of Bangladeshi males.
阑尾的解剖结构在其宏观尺寸上存在变化,其中一些变化可能会影响阑尾的临床方面。 使用孟加拉国作为样本的阑尾解剖学研究有限,无法产生任何标准化的人体测量数据。 这项研究主要是一项横断面观察性研究,还使用了一些统计分析来了解变量之间的关系。
检查了 56 个成年男性死后的阑尾及其附件,以检查其宏观特征。 通过统计分析评估了变量之间可能存在的相互关系。 样本的年龄范围为 18 至 67 岁。 阑尾最常见的位置是回肠后位(53.57%),其次是骨盆位(30.35%)、回肠后位(12.5%)和盲肠下位(3.5%)。
在大多数情况下(62.5%),阑尾系膜未到达阑尾尖端。 阑尾长度从 6.00 厘米到 16.30 厘米不等,平均值(±标准差)和中位数分别为 10.21 ±2.50 厘米和 10.00 厘米。 阑尾根部距离回盲部 1.90 至 3.80 厘米。 阑尾的其他宏观测量值是在阑尾根部、中部和尖端进行的,三个测量值的平均值被认为是整体值。 因此,阑尾的总外径在 0.32 厘米至 0.83 厘米之间变化。 评估不同变量之间可能存在的相关性表明,受试者年龄与阑尾长度之间存在显著负相关。
本研究的数据可能为孟加拉国男性阑尾的人体测量信息标准化提供基线,并提供一些以前的数据。
