1

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

2

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

3

hepatoduodenal ligament - connects / structured contained/

- connects liver to duodenum
-contrains portal triad ( proper hepatic artery, portal fein, bile duct)

4

gastrohepatic ligament - connects / structured contained/

- connects liver to lesser curvatur of stomach
-contains gastric arteries

5

gastrocolic ligament - connects / structured contained/

- connects greater curvature and transverse colon
- gastroepiploic arteries

6

gastrosplenic ligament - connects / structured contained/

- connects greater curvarue and spleen
- contains short gastrics, left gastroepiploic vessels

7

splenorenal ligament -connects / structured contained/

-connects spleen to posterior abdominal wall
-contains splenic arteries and vein, tail of pancreas

8

omentum is a

layer of peritoneum that surrounds abdominal organs:

9

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)

10

greater omentum

fold of visceral peritoneum that hangs down from the stomach ( ligaments that are part: Gastrocolic, gastrosplenic)

11

the lesser sac is

the cavity in abdomen that is behing the lesser omentum and the stomach

12

the greater sac is

the cavity in the abdomen that is inside the peritoneum but outside the lesser sac

13

connection betwwen greater and lesser sac

omental foramen ( epiploic foramen of Winslow)

14

pringle maneuver

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

15

spleen - intra or retroperitneal ?

intraperitoneal

16

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

17

ligament tha may be cut during surgery ( why )

gastrohepatic --> to access lesser sac

18

• The falciform ligament connects which two structures?

The liver and the abdominal wall

19

• In the gastrointestinal tract, the gastrohepatic ligament connects which two structures?

The liver and the lesser curvature of the stomach

20

• 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

21

• 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

22

• The ____ ligament connects the liver and the duodenum.

Hepatoduodenal

23

• During surgery, the gastrohepatic ligament is severed. Blood flow to which organ is impaired?

The stomach (gastric arteries)

24

• The gastrocolic ligament contains what structures?

The gastroepiploic arteries

25

• What vessels are contained within the gastrosplenic ligament?

Short gastrics, left gastroepiploic vessels

26

• The splenorenal ligament contains what structures?

The splenic artery and vein, tail of pancreas

27

• 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)

28

• The surgeon needs to access the lesser sac during surgery. Which of the patient's gastrointestinal ligaments can be cut?

The gastrohepatic ligament

29

• What ligament is part of the greater omentum?

The gastrocolic ligament

30

• 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)

31

• What ligament is a derivative of the ventral mesentery?

The falciform ligament

32

• A researcher dissects the falciform ligament. He finds vein remnants inside. What has he uncovered?

The ligamentum teres hepatis (derivative of fetal umbilical vein)

33

• 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

34

• A surgeon carefully cuts into a ligament separating the greater curvature and spleen. He aims to avoid bleeding from which specific vessels?

Short gastrics and left gastroepiploic vessels (this is the gastrosplenic ligament)
