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'.

The duodenal bulb (also ampulla of duodenum, duodenal ampulla, or duodenal cap) is the initial, dilated portion of (the superior part of) the duodenum [1] just distal to the stomach; it begins at the pylorus and ends at the neck of the gallbladder. It is normally about 5 centimeters long.
Superior mesenteric artery compressing the duodenum, featuring the superior mesenteric artery syndrome. Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery.
Vasa recta are straight arteries arising from arterial arcades (anastomoses of the jejunal and ileal arteries, branches of superior mesenteric artery) in the mesentery of the jejunum and ileum that supply the jejunum and ileum. [1] The vasa recta of the jejunum are long and few, compared to the ileum where they are numerous and short.
The large intestine is primarily supplied by the right colic artery, middle colic artery, and left colic artery. They do not supply the duodenum of the small intestine. The duodenum is primarily supplied by the inferior pancreaticoduodenal artery and superior pancreaticoduodenal artery.
A peptic ulcer is a defect in the inner lining of the stomach or duodenum typically due to excessive stomach acid. Extension of the ulcer through the lining of the digestive tract results in spillage of the stomach or intestinal contents into the abdominal cavity, leading to an acute chemical peritonitis.
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.
Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, and constipation.Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischemia or perforation from prolonged distension or ...
