“…The higher incidence of AA in the young adults may be closely associated with these structural components that changes with age. In Bakar's study [14], it has been reported that the diameter of the appendix vermiformis and the overall number of germinal centers show a negative correlation with the age of the subjects. Although the authors thought that higher frequency of AA is not related with the luminal diameter of the appendix vermiformis and the number of mucosal glands, they recommended further studies to find out the correlation between the number of germinal centers and the incidences of AA in association with the different age groups.…”

“…Therefore, AA in the elderly is a controversial issue that necessitates further pathophysiological explanation. The lymphoid structure of the appendix vermiformis begins to decrease in the early adulthood, and atrophied and obliterated at the older ages [14]. Additionally, the size of the appendix vermiformis begins to decrease from the early adulthood.…”

Aim: Although appendicitis is a disease of the young, it has been speculated that its incidence has increased among the elderly people. In this study, it was aimed to evaluate annual changes of appendicitis seen in older patients (!60 years) throughout a 10-year period. Methods: All adult patients who were surgically treated for acute appendicitis were retrospectively analyzed with respect to pathological analysis, gender, age and proportion of the patients aged 60 or over in an annual base. Variability in the mean age and proportion of the older patients aged 60 or over throughout the study years were regarded as the main outcomes. Results: There were 3296 patients with a mean age of 30.42 ± 12 years. Distribution of gender was similar (p ¼ 0.636). There was a significant positive correlation in the mean age of the patients throughout the study years (p ¼ 0.043). Stratification by the age of 60 yielded a significant increase in percent of the older patients, from 0.93% at 2007 to 4.28% at 2016 (p ¼ 0.019). Conclusions: The mean age of the patients with acute appendicitis is going to increase. Therefore, it is expected that all surgeons are more likely to be confronted with elderly patients with appendicitis in the near-future.

“…5 Appendix has irregular lumen due to lymphoid nodules and mucosal glands range from42-130 in number at different age groups. 6 The histological differentiation of vermiform appendix shows that it is a specialized organ. 7 At different age groups the circular, longitudinal muscular layers and sub mucosa varies in thickness considerably.…”

Objectives: To understand the histopathology of various diseases of vermiform appendix, the knowledge of normal histology of the organ at different age group is mandatory. Study Design: Comparative study. Setting: Islamic International Medical College Rawalpindi. Period: January 2014 to March 2015. Material and Methods: Total forty negative appendectomy/normal appendices specimens removed along with other abdominal operations were included in this study. Four equal groups (10 specimens in each) were made, spacing 15 years between each group. The last group had no upper age limit due to less availability of the specimens. The middle parts of specimens were included in this study the various parameters i.e. wall thickness, lymphoid nodules and lumen sizes were measured under microscope after calibration in micrometers after staining. Results: The lumen size decreases with advancing age. There was inverse relationship between lumen size and wall thickness. Surprisingly sum of mean lumen size and mean wall thickness of all age groups had no much difference. The number and size of lymphoid nodules decreases with advancing age. Conclusion: Although lumen size decreased as age advances but did not obliterate completely till 74 years age. The number and size of lymphoid nodule decreased but wall thickness size remained same and they are observed even at the age of 74 years.

“…And because of lymphatic follicle number decreasing with advances of age, the appendix weight also decreases and the area will be replaced by connective tissues (Rahman, et al, 2008). At different ages, the lumen has various shape and size, because of the changes of lymphatic follicles number, as well as the number of mucosal glands also varied (Bakar et al,2016). This study aimed to diagnose the age and sexrelated changes of the wall thickness, lumen diameter, number of lymphoid follicles and its diameter for male and female histomorphometrically.…”

Vermiform appendix varies in length from 2-20cm (Gupta et al,. 2012). Many changes in the structure of this organ may occur with aging among that good thickness, shortening, and atrophy of the muscular coat (Eliseev,1979). Lymphoid involution was observed in many studies (Eliseev,1979; Shcherbakov,1980). In the past vermiform appendix was considered as unimportant part, but then after, they found that it is not a useless part in humans (Zahid, 2004).
