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 retroduodenal arteries are several [1] [2] small [2] arteries which usually [1] arise from the gastroduodenal artery [1] [2] posterior to the superior part of duodenum, but may also arise from the posterior superior pancreaticoduodenal artery.
Secondarily retroperitoneal, meaning the structures initially were suspended in mesentery and later migrated behind the peritoneum during development [3] the duodenum, except for the proximal first segment, which is intraperitoneal [4] ascending and descending portions of the colon (but not the transverse colon, sigmoid and the cecum)
The common duct then opens medially into the descending part of the duodenum at the major duodenal papilla. The common duct usually measures 2-10mm in length. [1] The ampulla of Vater is an important landmark halfway along the second part of the duodenum marking the transition from foregut to midgut. [citation needed]
In the lower part of the descending portion, below the point where the bile and pancreatic ducts enter the small intestine, they are very large and closely approximated. In the horizontal and ascending portions of the duodenum and upper half of the jejunum , they are large and numerous. [ 3 ]
As the second part of the duodenum is anatomically in a retroperitoneal location (that is, behind the peritoneal structures of the abdomen), perforations due to sphincterotomies are retroperitoneal. Sphincterotomy is also associated with a risk of bleeding. [ 22 ]
the third part of the duodenum, a segment of the small intestines (can be compressed by the SMA at this location, leading to superior mesenteric artery syndrome). uncinate process of pancreas - this is a small part of the pancreas that hooks around the SMA. The SMA typically runs to the left of its associated vein, the superior mesenteric vein ...
The artery supplies the anterior and posterior sides of the duodenum and head of pancreas, with the anterior branch supply the anterior surface and similarly for the posterior. The artery supplies the part of the duodenum proximal to the level of the major duodenal papilla of the descending part of the duodenum. [3]
