The suspensory muscle of duodenum (also known as suspensory ligament of duodenum, Treitz's muscle or ligament of Treitz [1]) is a thin muscle connecting the junction between the duodenum and jejunum (the small intestine's first and second parts, respectively), as well as the duodenojejunal flexure to connective tissue surrounding the superior mesenteric and coeliac arteries.
The cystoduodenal ligament is an abnormal peritoneal fold that attaches the duodenum to the gallbladder, representing a rare variation in the anatomy of the lesser sac and its foramen. [ 2 ] Another variation sometimes present at the duodenal termination of the hepatoduodenal ligament is the duodenorenal ligament which passes to the front of ...
The duodenal bulb is a remnant of the mesoduodenum, a mesentery that suspends the organ from the posterior abdominal wall in fetal life. [10] The first part of the duodenum is mobile, and connected to the liver by the hepatoduodenal ligament of the lesser omentum. The first part of the duodenum ends at the corner, the superior duodenal flexure.
By mobilizing the duodenum and pancreas, surgeons gain exposure to the structures in the hepatic portal area. Exposure of hepatoduodenal ligament: The procedure facilitates the dissection and exposure of the hepatoduodenal ligament. This exposure is crucial for various hepatic and biliary surgeries. Visualizing the common bile duct:
The duodenum is the first and shortest section of the small intestine. It is a hollow, jointed C-shaped tube connecting the stomach to the jejunum. It starts at the duodenal bulb and ends at the suspensory muscle of duodenum. The attachment of the suspensory muscle to the diaphragm is thought to help the passage of food by making a wider angle ...
Anatomically, the lesser omentum is divided into ligaments, each starting with the prefix "hepato" to indicate that it connects to the liver at one end. Most sources divide it into two parts: [1] hepatogastric ligament: the portion connecting to the lesser curvature of the stomach; hepatoduodenal ligament: the portion connecting to the duodenum
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'.

Duodenal glands are situated within the mucosa and submucosa of the duodenum. They are most abundant near the pylorus, growing shorter and more sparse distally towards the terminal portion of the duodenum. [1] The duodenum can be distinguished from the jejunum and ileum by the presence of Brunner's glands in the submucosa. [citation needed]
