Is the ligament of Treitz a muscle?
The suspensory muscle of duodenum is a thin muscle connecting the junction between the duodenum, jejunum, and duodenojejunal flexure to connective tissue surrounding the superior mesenteric artery and coeliac artery. It is also known as the ligament of Treitz.
What is the suspensory 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.
Where does the ligament of Treitz originate?
The second part of the ligament of Treitz is a thin muscular band originating from the celiac trunk as a connective tissue band. It passes between the splenic vein, left renal vein and the pancreas to insert at the duodenojejunal flexure (DJ flexure) and part of the inferior aspect of the transverse duodenum.
Where is the angle of Treitz?
duodenum
The angle of Treitz is also known as the ligament of Treitz and is the junction of the duodenum and jejunum adjacent to the mesenteric vessels.
What is Treitz ligament?
The ligament of Treitz is a thin band of tissue (peritoneum) that connects and supports the end of the duodenum and beginning of the jejunum in the gastrointestinal (GI) tract. It’s also called the suspensory muscle of duodenum.
How long is jejunum?
The jejunum is roughly 2.5 meters in length, contains plicae circulares (muscular flaps), and villi to absorb the products of digestion. The ileum is the final portion of the small intestine, measuring around 3 meters, and ends at the cecum.
What is in the Hepatoduodenal ligament?
[7] The hepatoduodenal ligament has lymphatic pathways, which will flow into the Pecquet cistern at a sub-diaphragmatic level. It also has the name “pars tensa” of the small omentum; its thickness contains the portal triad, that is, the portal vein, the hepatic artery, and the common bile duct.
What is Valve of Kerking?
Anatomical terminology. The circular folds (also known as valves of Kerckring, valves of Kerchkring, plicae circulares, plicae circulae, and valvulae conniventes) are large valvular flaps projecting into the lumen of the small intestine.
What is the function of the jejunum?
It is between the duodenum (first part of the small intestine) and the ileum (last part of the small intestine). The jejunum helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body.
What happens in jejunum?
Jejunum function The main function of the jejunum is absorption of important nutrients such as sugars, fatty acids, and amino acids. Peristalsis, the involuntary contraction of smooth muscles that moves nutrients through the digestive system, is vigorous and quick in the jejunum.
Where is the ligament of Treitz located in the body?
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 celiac artery. The second, muscular, part descends from said connective tissue to the duodenum, between the pancreas and the left renal vein.
Can a large amount of extrinsic mass affect the ligament of Treitz?
A large amount of extrinsic mass may lead to a displacement of the duodenum, and the ligament of Treitz cannot keep this from happening. The ligament has a vital role in the rotation of the stomach and also in the identification of certain gastrointestinal anomalies.
How are ligaments and tendons similar to each other?
Tendons are similar to ligaments, except these tension-withstanding fibrous tissues attach muscle to bone. Tendons consist of densely packed collagen fibers. Muscles, either individually or in groups, are supported by fascia.
How is the ligament of Treitz preserved during Whipple’s procedure?
During a Whipple’s procedure, commonly used to treat pancreatic cancer by removing the pancreas, duodenum, and part of the jejunum, the ligament of Treitz is separated from the duodenum and preserved. When the remaining jejunum is anastamosed with the pylorus of the stomach, it may be passed through the ligament.
