Background. Meckel?s diverticulum (MD) is a congenital anomaly of the small intestine. It results from incomplete obliteration and resorption of the proximal omphaloenteric duct connecting yolk sac with primitive gut in the fetal period. Case report. A case of 20-year old female with ectopic pancreatic rests in a MD was reported. She was hospitalized with clinical signs of acute appendicitis. During surgery an inflamated Meckel?s diverticulum was found and a clinoid resection of the diverticulum was performed. Histologic examination revealed pancreatic tissue in the removed diverticulum. Endocrine cells (EC) were detected with Masson staining and aberrant pancreatic tissue with immunocytochemical LSAB2 method using pan cytokeratin as epithelial marker. Conclusion. Most of MD are asymptomatic and accessory finding during laparothomias for different causes, but complications of undiagnozed MD can be serious (diverticulitis, perforation with peritonitis or intestinal obstruction caused by invagination). In unclear cases, additional cytochemical and immunocytochemical diagnostics could be done.

Myenteric Plexuses

The nervous and endocrine systems jointly control intestinal movements, secretions of their glands and also participate of the processes of nutrient digestion and absorption. Therefore, the central objective of this study was to verify the existence of a possible relationship between the number of nervous cells and ganglia of the submucosal and myenteric plexuses and the number of endocrine cells in the small intestine of adult D. aurita. The utilized staining techniques were Grimelius, modified Masson-Fontana, direct immunoperoxidase and H-E. Argyrophillic, argentaffin and insulin immunoreactive endocrine cells do not numerically vary between the initial, mid and final regions of the duodenum, jejunum and ileum (P>0.05), except for argyrophillic cells in the jejunum (P>0.05). No numerical relationship has yet been verified between the number of nerve ganglia and endocrine cells, and also between nervous and endocrine cells. We recommended the use of new immunohistochemical techniques to confirm the numerical correlation between the nervous and endocrine systems in the small intestine. The morphology and distribution of endocrine cells and the nerve ganglia studied were similar to those encountered in eutherian mammals.
