Ligament of Treitz

The ligament of Treitz, also known as the suspensory ligament of the duodenum, is a double fold of peritoneum suspending the duodenojejunal flexure from the retroperitoneum.

It is often used interchangeably with duodenojejunal flexure.

The ligament of Treitz is comprised of two parts, the first of which passes from the right crus of the diaphragm to connective tissue surrounding the coeliac artery. The second, muscular, part descends from said connective tissue to the duodenum, between the pancreas and the left renal vein. It is the second part that actually suspends the duodenojejunal flexure. 1

The ligament of Treitz is a landmark

Congenital superior mesenteric artery syndrome can be caused by a short ligament of Treitz.

In adults, the ligament often involutes or is entirely absent. Hence, it is virtually impossible to image 1,2. Its location can be inferred from its anatomical relations (see duodenojejunal flexure).

It is named after Czech pathologist Václav Treitz, who described it in 1853, referring to it as the "suspensory muscle of the duodenum".
