Abstract/OtherAbstract:
To investigate the factors affecting the development of the ligament of Treitz, we examined sagittal and frontal histological sections of 35 human fetuses with a crown-rump length of 100-300 mm (approximately 16-38 weeks of gestation). The retropancreatic fascia consistently extended in a layer behind the pancreatic body and the splenic artery and vein, and also in front of the left renal vein and left adrenal. In 18 specimens, a connective tissue band was seen originating from the diaphragmatic crus around the esophageal opening and ending at the retropancreatic fascia to the left of the origin of the celiac artery. In 10 of these 18 specimens, these putative upper parts of the ligament contained striated muscles, or so-called Hilfsmuskel. Although most of other 17 specimens were larger fetuses, the left adrenal, the liver caudate lobe and the celiac ganglion made space for the ligament very limited. In 22 specimens including the above 18, the retropancreatic fascia extended inferiorly to approach the fourth portion of the duodenum (D4) or the duodenojejunal junction (DJJ). However, in 11 of the 22 examples of the putative lower part of the ligament, the connection between the duodenal muscle coat and the fascia was interrupted by developing lymphatic tissues. Consequently, the ligament of Treitz seemed to develop from both pleuroperitoneal membrane-derived cells and the retropancreatic fusion fascia, although the morphology was markedly modified by adjacent structures such as the adrenal gland. The ligament may "recover" after the adrenal becomes reduced in size after birth.
