Background. Aim of ­this ­research is to ­study the sit­u­a­tion and rela­tion­ships of the ­adrenal ­gland in the ­first ­stage of devel­op­ment in ­order to ­give ­some con­trib­utes for the appli­ca­tion of lapar­os­copic adren­a­lec­tomy; in the mean­time we ­describe the ­series of the ­debat ­changes occur­ring in the con­sti­tu­tion of the ­cortex and ­medulla.
Methods. Analysis of his­to­logic ­slices of tho­raco-abdom­inal and abdom­inal ­regions of ­human ­embryos and ­fetuses ­ranging ­from the ­fifth (12 mm CR) to the twen­tieth ­week (170 mm CR).
Results. At 12 mm CR an ­unique ­type of ­cells is ­present in the ­cortex; at 16 mm CR ­there are two dif­ferent ­groups of ­cells. Sympathogonia ­enter ­into the ­cortex at 16 mm CR. The ­right ­adrenal ­gland ­seems ­enclosed ­into the ­liver and a lig­a­ment con­taining the ­middle ­adrenal ­vein ­reaches the ­vena ­cava infe­rior ­sulcus. The ­left ­adrenal ­gland, ­through the ­coelomic ­cavity, is in rela­tion­ship ­with the ­stomach, the ­medial ­border of the ­spleen and the pan­creatic ­body con­tained in the prim­i­tive ­dorsal mes­o­gas­trium.
Conclusions. The ­timing of pen­e­tra­tion of the gan­gliar ­cells ­into the ­cortex is ­defined as ­well as the hypoth­esis ­that the ­matrix of the ­fetal and defin­i­tive ­cortex is the ­same: more­over the ­study of the ­early devel­op­ment ­allows to under­stand the ­main char­ac­ter­is­tics of ­both the ­adrenal ­glands ­which are sig­nif­i­cant for a ­rational and dif­fe­ren­tial lapar­os­copic ­approach.
