Flashcards in 6. Important GI ligaments Deck (34):
important gastrointestinal ligaments and what they connect
1. falciform - liver to anterior abdmonial wall
2. Hepatoduodenal - liver to duodenum
3. gastrojepatic - liver to lesser curvature of stomach
4. gastocolic- greater curvature to transverse colon
5. Gastrosplenic - greater curvature to spleen
6. splenorenal - spleen to posterio abdominal wall
falciform ligamen - connects / structured contained/ derivative
- connects liver to anterio abdominal wall
-contains ligamentum teres hepatis
-falciform is derivatice of ventral mesentery, ligamentum teres
hepatis is derivative of fetal umbilican vein
hepatoduodenal ligament - connects / structured contained/
- connects liver to duodenum
-contrains portal triad ( proper hepatic artery, portal fein, bile duct)
gastrohepatic ligament - connects / structured contained/
- connects liver to lesser curvatur of stomach
-contains gastric arteries
gastrocolic ligament - connects / structured contained/
- connects greater curvature and transverse colon
- gastroepiploic arteries
gastrosplenic ligament - connects / structured contained/
- connects greater curvarue and spleen
- contains short gastrics, left gastroepiploic vessels
splenorenal ligament -connects / structured contained/
-connects spleen to posterior abdominal wall
-contains splenic arteries and vein, tail of pancreas
omentum is a
layer of peritoneum that surrounds abdominal organs:
lesser omentum ( and ligaments)
double layer of peritoneum that extends from the liver to the lesser curvature of th stomach ( hepatogastric ligament) and the first part of the duodenum ( hepatoduodenal ligament)
fold of visceral peritoneum that hangs down from the stomach ( ligaments that are part: Gastrocolic, gastrosplenic)
the lesser sac is
the cavity in abdomen that is behing the lesser omentum and the stomach
the greater sac is
the cavity in the abdomen that is inside the peritoneum but outside the lesser sac
connection betwwen greater and lesser sac
omental foramen ( epiploic foramen of Winslow)
hepatoduodenal ligament may be compressed between thumb and index finger paced in omental foramen --> interrupt the flow ( hepatic artery and portal vein ) --> control bleeding from the liver
spleen - intra or retroperitneal ?
ligaments - lesser and greater sacs sepation
gastrohepatic --> separates greater and lesser sacs on the righ
gastrosplenic --> separeates greater and lesser sac on the right
hepatoduodenal --> borders the omental forramen ( epiploic foramen of WInslow
ligament tha may be cut during surgery ( why )
gastrohepatic --> to access lesser sac
• The falciform ligament connects which two structures?
The liver and the abdominal wall
• In the gastrointestinal tract, the gastrohepatic ligament connects which two structures?
The liver and the lesser curvature of the stomach
• In the gastrointestinal tract, if the gastrocolic ligament were damaged, which of the patient's two structures would be disconnected?
The transverse colon and the greater curvature of the stomach
• In the gastrointestinal tract, if the splenorenal ligament were damaged, which of the patient's two structures would be disconnected?
The spleen and the posterior abdominal wall
• The ____ ligament connects the liver and the duodenum.
• During surgery, the gastrohepatic ligament is severed. Blood flow to which organ is impaired?
The stomach (gastric arteries)
• The gastrocolic ligament contains what structures?
The gastroepiploic arteries
• What vessels are contained within the gastrosplenic ligament?
Short gastrics, left gastroepiploic vessels
• The splenorenal ligament contains what structures?
The splenic artery and vein, tail of pancreas
• Intraoperatively, the portal triad is noted to be bleeding. Through which opening can it be compressed to achieve hemostasis?
The omental foramen may be accessed to compress the hepatoduodenal ligament (compression is called the Pringle maneuver)
• The surgeon needs to access the lesser sac during surgery. Which of the patient's gastrointestinal ligaments can be cut?
The gastrohepatic ligament
• What ligament is part of the greater omentum?
The gastrocolic ligament
• The ligament that separates the right greater and lesser sacs connects the liver to which structure?
The lesser curvature of the stomach (gastrohepatic ligament, containing the gastric arteries)
• What ligament is a derivative of the ventral mesentery?
The falciform ligament
• A researcher dissects the falciform ligament. He finds vein remnants inside. What has he uncovered?
The ligamentum teres hepatis (derivative of fetal umbilical vein)
• A surgeon accidentally cuts into the hepatoduodenal ligament and notes bile-tinged bleeding. What specific structure(s) has he cut into?
The portal triad: proper hepatic artery, portal vein, common bile duct
