Q

What are peritoneal adhesions?

A

These can be caused by peritoneum infection, inflammation or surgery

Healing of above processes causes fibrous tissue to form between visceral peritoneum or between visceral and parietal peritoneum

Adhesions limits normal gut movement of viscera, causing abdominal pain, gut twisting or volvulus

Severe cases may need surgical intervention

Try to not damage the peritoneum when your hands or instruments are in peritoneal cavity

Q

A
31
Q

What are the characteristics of the visceral peritoneum? (pain)

A

Served by the same blood, lymph, and nerves as the organ it covers. Pain is poorly localized and is felt all over the body systems

32
Q

Does the peritoneal cavity contain organs?

A

NO!

33
Q

Describe the contents of the abdominal cavity?

A
34
Q

What vessels run between the transversalis fascia and the rectus abdominis muscle?

A

External iliac vessels

(Let me know if this is wrong not 100% sure about this)

35
Q

What is peritonitis?

A

Infection or inflammation of the peritoneum. It can result from traumatic penetration or rupture of abdominopelvic organs

Gas, fecal matter, and bacteria can enter peritoneal cavity

Exudate fills cavity

Pain, fever, gas under diaphragm when standing paralyzed bowel movements (NO SOUND)

36
Q

The transpyloric plane transects what? What vertebrae does it pass through?

A

The pylorus in supine or prone position

Passes through L1

37
Q

Make a table differentiating a direct and indirect inguinal hernia? (Predisposing factors, Frequency, Exit from abdominal cavity, Course, Exit from abdominal wall)

A
38
Q

What are the 9 regions of the abdomen?

A
39
Q

What is an abdominal paracentesis?

A

Surgical pencture of the peritoneal cavity for the aspiration or drainage of fluid

Avoid blood vessels and structures on the anteriolateral abdominal wall

If small quantity is removed, this is typically for diagnostic reasons. Therapeutic paracentesis refers to the removal of 5 liters or more of fluid to reduce intra abdominal pressure

40
Q

What is the difference between the Lesser sac and the greater sac?

A

Lesser - the space posterior to lesser omentum and stomach

Greater - The main and larger part of peritoneal cavity

41
Q

What are the main ligaments in the anterior abdominal wall above and the main folds below the umbilicus?

A
42
Q

What are the functions of the greater olmentum?

A
43
Q

What is ascites?

A

Excess fluid accumulation in peritoneal cavity

Results from internal bleeding, portal hypertension, cancer metastasis, starvation, etc.

Peritoneal cavity distended with several liters of fluid

Respiration and bowel movements are affected

44
Q

What are the abdominal structures formed by pertioneum?

A
45
Q

What is the location and characteristics of the rectus abdominus?

A
46
Q

What are some other locations of abdominal hernias?

A
47
Q

What are the characteristics of the mesenteries and what are three examples?

A
48
Q

Make a table of the boundaries of the inguinal canal?

A
49
Q

A
50
Q

The transumbilical plane is located at what vertebral disc?

A

In between L3 and L4

51
Q

What is the difference between the greater olmentum and lesser olmentum?

A
52
Q

Who is most likely to develop a hernia?

A

Men are eight times more likely to develop a hernia than females

Q

The deep inguinal ring is lateral to what?

A

Inferior epigastric artery and vein

What is the location and characteristics of the transverse abdominus muscle?

A
64
Q

What are the important dematomes in the anterior abdominal wall?

A
65
Q

What is important about the location of the scarpa fascia and the arcuate line?

Scarpa’s fascia - Beginning of about 2/3 of distance between imbilicus and pubic crest

Arcuate line - occurs about 1/2 of the distance from the umbilicus to the pubic crest

66
Q

Describe the pathology associated with omental bursa?
