Diagnostic Ultrasound - Abdomen and Pelvis
Bowel Falciform ligament STOMACH AND DUODENUM IN SITU Liver (left lobe) Fundus Cardia Anatomy: Abdomen Gallbladder Duodenal bulb Pylorus Antrum Body Gastroepiploic artery branches Gastrocolic ligament Transverse colon Greater omentum Hepatogastric ligament Left gastric artery Hepatoduodenal ligament Celiac artery Pyloric sphincter Inner (oblique) muscle layer Outer (longitudinal) muscle layer Middle (circular) muscle layer (Top) Graphic shows the stomach and proximal duodenum in situ. The liver and gallbladder have been retracted upward. Note that the lesser curvature and anterior wall of the stomach touch the underside of the liver and the gallbladder abuts the duodenal bulb. The greater curvature is attached to the transverse colon by the gastrocolic ligament, which continues inferiorly as the greater omentum, covering most of the colon and small bowel. (Bottom) Graphic shows the lesser omentum extending from the stomach to the porta hepatis, divided into the broader and thinner hepatogastric ligament and the thicker hepatoduodenal ligament. The lesser omentum carries the portal vein, hepatic artery, common bile duct, and lymph nodes. The free edge of the lesser omentum forms the ventral margin of the epiploic foramen. Note the layers of gastric muscle; the middle circular layer is thickest. 71
Bowel Anatomy: Abdomen DUODENUM Hepatoduodenal ligament Right kidney Root of transverse mesocolon Transverse mesocolon Pancreas Jejunum Transverse colon Duodenum (3rd portion) Superior mesenteric artery and vein Root of small bowel mesentery Hepatoduodenal ligament Pylorus Common bile duct Major papilla (of Vater) Pancreatic duct Proximal jejunum Superior mesenteric artery Superior mesenteric vein (Top) The duodenum is retroperitoneal, except for the bulb (1st part). The proximal jejunum is intraperitoneal. The hepatoduodenal ligament attaches the duodenum to the porta hepatis and contains the portal triad (bile duct, hepatic artery, portal vein). The root of the transverse mesocolon and mesentery both cross the duodenum. The 3rd portion of the duodenum crosses in front of the aorta and inferior vena cava (IVC) and behind the superior mesenteric vessels. The 2nd portion of the duodenum is attached to the pancreatic head and lies close to the hilum of the right kidney. (Bottom) Graphic shows the duodenal bulb suspended by the hepatoduodenal ligament. The duodenal-jejunal flexure is suspended by the ligament of Treitz, an extension of the right crus. The major pancreaticobiliary papilla enters the medial wall of the 2nd portion of the duodenum. 72
