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 ascending portion of the duodenum ascends on the left side of the aorta, as far as the level of the upper border of the second lumbar vertebra.At this point, it turns abruptly forward to merge with the jejunum, forming the duodenojejunal flexure.
The duodenorenal ligament is a fold of peritoneum that occasionally crosses from the duodenum at the termination of the hepatoduodenal ligament to the right kidney. [1] The duodenorenal ligament is an anatomic variation of the peritoneum, and is not commonly present. It is one of many factors that may hold the kidney in place when standing. [2]
The sphincter regulates the secretion of pancreatic juice and bile into the duodenum. [3] It also prevents reflux of duodenal contents into the ampulla of Vater. [4] By preventing reflux of the contents of the duodenum, the sphincter of Oddi prevents the accumulation of particulate matter and sludge in the bile ducts, reducing the risk of cholangitis.
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; In some cases, the following ligaments are considered part of the lesser omentum: hepatophrenic ligament: the portion connecting to the thoracic ...
The first part of the duodenum is the most common location of ulcers since it is where the acidic chyme meets the duodenal mucosa before mixing with the alkaline secretions of the duodenum. [24] Duodenal ulcers may cause recurrent abdominal pain and dyspepsia , and are often investigated using a urea breath test to test for the bacteria, and ...
The Pringle manoeuvre is used during liver surgery and in some cases of severe liver trauma to minimize blood loss. [1] For short durations of use, it is very effective at reducing intraoperative blood loss. [2] The Pringle manoeuvre is applied during closure of a vena cava injury when an atriocaval shunt is placed. [citation needed]
