Abstract

Background: The greater omentum of white rats appears, in basic morphological
features (in miniature), to be homologous to the greater omentum of humans. We
study of the greater omentum reaction to the catgut implant. After implantation of
the catgut thread, it turned out that not only the greater omentum, but also serous
formations similar to it, related to the testicles, are involved in the covering of the
implant. The aim of the study was to study the general plan of the structure and the
principles of morphometric analysis of serous formations of testis in white male rats.
Materials and methods: The experiment involved 15 white male rats of reproductive
age, weighing from 284 to 334 grams.
Results: It has been established that each testicle of white rats has serous (peritoneal
derivatives) formations of two types. One of them is a typical mesentery,
with which each testicle is separately fixed to the posterior wall of the pelvic
cavity, and the other formation is a free regrowth of a duplication of the serous
membrane. It was called the epididymal omentum. According to the algorithm
for studying the greater omentum in our previous works, it is noteworthy that the
area of the greater omentum is noticeably inferior to the area of the epididymal
omentums (F = 0.239; p = 0.006). So, if the average value of the area of the
greater omentum is 2766.51 ± 388.12 mm2, then the same indicator of the
epididymal omentum reaches 4383.36 ± 793.56 mm2, with their approximately
the same thickness (F = 1.35; p = 0.291).
Conclusions: It has been established that the greater omentum has two, homeomorphic
to it, derivatives of the peritoneum, associated with the epididymis,
which were justifiably called epididymal omentums and were fully described in
the literature for the first time.
