What is the Ligament of Treitz?
The ligament of Treitz, also known as the suspensory ligament of the duodenum, is a key part of the upper abdomen. It anchors the duodenojejunal flexure, where the duodenum meets the jejunum. This ligament is vital for the duodenojejunal flexure’s stability.
It connects to the duodenum’s connective tissue and muscles. Starting from the right crus of the diaphragm, it goes down to the duodenojejunal flexure and the mesenteric root. This ligament keeps the duodenojejunal flexure in place and stops the small intestine from moving too much.
Embryological Development
The ligament of Treitz develops in a unique way during fetal growth. Early on, the midgut rotates and fixes in place. The duodenum and jejunum attach to the back of the abdomen, with the ligament of Treitz playing a key role.
This ligament forms from the fusion of peritoneal folds and mesenchymal tissue around the duodenojejunal junction. As it grows, it strengthens and keeps the duodenojejunal flexure in its correct position. This prevents the intestines from twisting or moving out of place.
Knowing how the ligament of Treitz develops helps us understand its role and how it can be affected by congenital issues. Problems like intestinal malrotation or volvulus can occur during development.
Anatomical Structure of the Ligament of Treitz
The ligament of Treitz is key in the upper GI tract’s surgery. It’s a band of connective tissue. It’s a major guide for surgeons near the duodenojejunal flexure.
This ligament is made of both muscle and fibrous parts:
