STRUCTURAL FEATURES OF ADULT ANAL GLANDS (MACRO-MICROSCOPIC EXAMINATION)

Abstract

The aim: to study the macro-microscopic anatomy of the anal glands in adults under the conditions of relative norm.Material and methods: using the MBS-9 binocular stereomicroscope, the size characteristics and structural features of the anal glands from the corpses of 136 people (69 men and 67 women) aged 20-99 were studied. Preparations were stained with 0.05% methylene blue solution.Results: the total number of anal glands varies individually from 0 (in people over 80 years old) to 38 (aged 30-39 years). On total preparations of the anal canal after elective staining, the glands are identified as black (dark blue) compact anatomical formations. The gland can have from one to five end pieces, which, when connecting, form a common excretory duct, which opens with a rounded (oval) mouth at the bottom or side wall of the anal sinus. In the course of the common excretory duct, a local ampoule-like expansion is sometimes formed, which also varies in people of different age groups.Conclusion: the study allowed us to obtain previously unknown data on the macro-microscopic structure of the anal glands,their quantitative and age-related features, to identify the rate of development of involutive changes in the glandular apparatus of this part of the colon.
