38
Q

A

umbilicus

39
Q

General term for contents of the abdomen

A

viscera

40
Q

falciform ligament

A

a double-layered extension of parietal peritoneum that sweeps off the anterior abdominal wall to divide the liver into the asymmetric left and right lobes.

41
Q

Where is the right colic flexure. Sometimes called hepatic flexure.

A

Fold between the ascending and transverse colon. Near the liver.

42
Q

Where is the left colic flexure. Sometimes called splenic flexure

A

Fold between transverse colon and descending (left) colon. Near the spleen.

43
Q

Name the four lobes of the liver.

A

left, right, caudate and quadrate

44
Q

How many functionally independent segments of the liver, all receiving their own blood supply & lymph drainage?

A

8

45
Q

Explain parietal vs visceral peritoneum

A

Your parietal peritoneum lines your abdominal and pelvic walls and your visceral peritoneum wraps around your organs. Your peritoneal cavity is the space in between.

46
Q

What is the Greater Sac of the Peritoneum?

A

Distal to the Lesser Sac, the greater sac is the larger portion of the peritoneal cavity and comprises the majority of the peritoneal cavity. It is further divided into two compartments by the mesentery of the transverse colon (known as the transverse mesocolon):

Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen.

Infracolic compartment – lies below the transverse mesocolon and contains the small intestine, ascending and descending colon. The infracolic compartment is further divided into left and right infracolic spaces by the mesentery of the small intestine.

47
Q

What is the Lesser Sac of the Peritoneum?

A

Lesser Sac (Omental Bursa)
Proximal to the Greater Sac, the lesser sac lies posterior to the stomach and lesser omentum. It allows the stomach to move freely against the structures posterior and inferior to it.

The omental bursa is connected with the greater sac through an opening in the omental bursa – the epiploic foramen (of Winslow).

The epiploic foramen is situated posterior to the free edge of the lesser omentum (the hepatoduodenal ligament).

48
Q

What is another name for Omental Bursa?

A

Lesser Sac (of the peritoneum)

49
Q

The Greater Sac (of the Peritoneum) can be further divided into two compartments, name and describe what structures are housed in each compartment.

A

Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen.

Infracolic compartment – lies below the transverse mesocolon and contains the small intestine, ascending and descending colon. The infracolic compartment is further divided into left and right infracolic spaces by the mesentery of the small intestine.

50
Q

What is ascites?

A

While the peritoneal cavity is ordinarily filled with only a thin film of fluid, it is referred to as a potential space because excess fluid can accumulate in it, resulting in the clinical condition of ascites

51
Q

What is another term for Cephalad?

Hint: Used as an anatomical term when describing embryos.
Hint: Cephalic

A

Cranial

52
Q

What is the ligament of Treitz?

A

The ligament of Treitz is a thin band of tissue (peritoneum) that connects and supports the end of the duodenum and beginning of the jejunum in the small intestine

53
Q

What is another term for the Biliopancreatic limb?

A

Duodenum

54
Q

The Roux limb is also known as the…

A

Jejunum

55
Q

What are the benefits of the Lembert suture technique?

A

Designed to encourage wound-edge inversion. Creates a natural crease. Used to recreate the alar creases and define the helical rim. Also useful when recreating the mental crease.

56
Q

What is the Alar Crease? Not really related to any of the procedures you have covered…

A

Area of external skin where nostril meets cheek… alar = nostril

57
Q

What is the helical rim? Not relevant to cases you will be covering

A

Curvature of the external ear

58
Q

What is the mental crease? Not relevant to cases you will be covering

A

Also known as the chin crease, is the horizontal crease that forms between the lower lip and above your chin. This crease is formed by the chin’s mentalis muscle and can be a single groove of varying depths, or in some people, may appear as multiple wrinkles or folds.

59
Q

The surgical cutting open of the intestine.

A

Enterotomy

60
Q

Surgical incision into the stomach.

A

Gastrotomy

61
Q

The creation of an artificial external opening into the stomach for nutritional support or gastric decompression.

A

Gastrostomy

62
Q

Endoscopy

A

Endo, a prefix from Greek ἔνδον endon meaning “within, inner, absorbing, or containing”.
An endoscope is a medical device with a light attached. It is used to look inside a body cavity or organ. The scope is inserted through a natural opening, such as the mouth during a bronchoscopy, or the rectum for a sigmoidoscopy. A medical procedure using any type of endoscope is called an endoscopy.

63
Q

Name of dye agent used to visualise structures in surgery

A

Methylene Blue

64
Q

What are cc a measure of?

A

Cubic centimeter = volume
1 cc = 1mL
They are just different names for the same volume. One milliliter equals exactly one cubic centimeter.

65
Q

What is the Petersen’s defect?

A

Petersen’s hernia is a type of internal hernia, in which part of the intestinal loop protrudes through a defect between small bowel limbs, transverse mesocolon, and retroperitoneum. It has been reported in individuals undergoing gastrojejunostomy (GJ), especially following bariatric surgeries

66
Q

What is the main feature of a Jackson Pratt drain?

A

External bulb / balloon that allows patient to drain contents when full. Used in Laparoscopic Roux-en-Y Gastric Bypass sx. Drain is left in situ post sx until removed.
