Morphological studies on Meckel's diverticulum in geese (Anser anser domesticus)

This study was carried out to reveal the morphological features of Meckel's diverticulum (MD) in geese. For this purpose, a total of 36 adult healthy geese of both sexes, 50-52 weeks of age, were used. The mean weight of MD in male was found to be significantly larger than that of female. It was located a little distal to the midpoint of the small intestine in both sexes. It had a lot of lymphoid tissues, the simple columnar epithelium and a small number of crypts, and was a lack of villi, and its muscularis mucosae was very thin. Results from this study are thought to throw light on future studies on MD and proper diagnosis of pathological disorders related to it, and to contribute considerably to the present anatomical knowledge on MD in geese.
