In 63 series of histological sections of human embryos and prefetuses (4-13 weeks) and in 30 corpses of fetuses and stillborns it has been stated that during the 4th week certain changes occur resulting in formation of the lesser peritoneal sac. It further develops into 3 sections: vestibulum bursae omentalis, bursa omentalis proper and cavity of the omentum majus. Spatial-temporal organization of the lesser peritoneal sac is neither connected with development of separate organs or structures, nor with independent growth, but with the process of development of the whole organocomplex of the upper part of the abdominal cavity, formation of topography and organs' fixation, growth peculiarities of the dorsal mesogastrium. The bursa omentalis proper is forming at the expense of retransformation of the hepatogastric pocket, dependent on growth of the dorsal mesogastrium and on a change in the stomach position. The vestibulum bursae omentalis appears in connection with development and formation of the liver topography, lesser omentum and duodenum. The right pulmoesophagial pocket is interrupted by a developing diaphragm with formation of the superior torsion of the bursa omentalis. Disorders in fixation processes of the organs in the superior part of the abdominal cavity and formation of the bursa omentalis topography can serve as a morphological prerequisite for cysts developing in the retroperitoneal space and hernias of the foramen epiploicum.
在63组人类胚胎和胎儿（4 - 13周）的组织学切片以及30具胎儿和死产儿尸体中发现，在第4周会发生某些变化，导致小网膜囊形成。它进一步发展为3部分：网膜囊前庭、固有网膜囊和大网膜腔。小网膜囊的时空组织既不与单独器官或结构的发育相关，也不与独立生长相关，而是与腹腔上部整个器官复合体的发育过程、局部解剖结构的形成和器官的固定、胃背系膜的生长特点相关。固有网膜囊是由肝胃隐窝的再转变形成的，这取决于胃背系膜的生长和胃位置的变化。网膜囊前庭的出现与肝脏局部解剖结构、小网膜和十二指肠的发育及形成有关。右肺食管隐窝被发育中的膈肌中断，导致网膜囊上扭转的形成。腹腔上部器官固定过程的紊乱以及网膜囊局部解剖结构的形成可能是腹膜后间隙囊肿和网膜孔疝发生的形态学前提。
