AB-Abdominal Wall

Question 1

Site for abscess formations

Answer 1

lesser sac, subphrenic, subcapular

Question 2

Mallignant/Inflammatory Ascites

Answer 2

characterized by:
septation
loculation
fine or course internal echoes 
unusual distribution
matting or clumping of bowel loops
thickening of interface between fluid and neighboring structures

Question 3

Clinical symptoms of infection

Answer 3

increased white blood cell count
pain
fever
warmth
palpable

Question 4

What is Inflammatory Ascites usually linked to?

Answer 4

Cancer

Colisticyticis Disease Process

Question 5

Biloma

Answer 5

Extrahepatic collection of bile that may develop because of iatrogenic, traumatic, or spontaneous rupture of the Biliary tree

Question 6

Urachal Cyst

Answer 6

incomplete regression of the urachus during development
-becomes obliterated and forms a fibrous core-urachus
runs from the apex of the baldder to the belly button
(oozing fluid collection from belly button seen in babies)

Question 7

Greater Omentum

Answer 7

Peritoneal Cavity, apron like fold over stomach

it is filled with blood vessels by the epiploic branches of the gastroepiploic vessels and helps combat infection

Question 8

Lymphocele

Answer 8

collection of fluid that occurs after surgery in pelvis
creates pressure and pusses bowel away- unlike ascites.
(occurs in approx. 12% of all transplant patients)

Question 9

Peritoneum

Answer 9

Smooth membrane that lines the entire abdominal cavity and is reflected over contained organs

Question 10

Sepsis

Answer 10

spread of infection from initial site into the bloodstream

Question 11

Differential diagnosis for lesser sac abscess

Answer 11

pseudocyst
pancreatic abscess
gastric outlet obstruction
fluid-filled stomach

Question 12

Hydatid cyst in the spleen

Answer 12

usually seen in cattle-rearing or sheep herding areas
appears as a cyst within a cyst
caused by a parasitic tapeworm

Question 13

Candidiasis

Answer 13

a kind of infection

common in AIDS patients

Question 14

Hernia

Answer 14

protrusion of peritoneal lined sac
umbilical, femoral areas
strangulation, interruption of blood
incarcerated, can not be pushed back

Question 15

The peritoneal cavity is made up of..

Answer 15

multiple peritoneal ligaments and folds that connect the viscera to each other and to the abdominopelvic walls

Question 16

Within the cavity

Answer 16

Lesser and greater omentum
Mesenteries
Ligaments
Multiple fluid spaces (lesser sac, perihepatic and subphrenic spaces)

Question 17

Parietal peritoneum

Answer 17

The part that lines the walls of the cavity

Question 18

Visceral peritoneum

Answer 18

The part covering the abdominal organs to a greater or lesser extent

Question 19

Lesser omentum

Answer 19

double layer of peritoneum, extending from the liver to the lesser curvature of the stomach.

Question 20

Greater sac

Answer 20

general peritoneal cavity

Question 21

Lesser sac

Answer 21

Peritoneal recess posterior to the stomach

Extends to the diaphragm

Question 22

The lesser sac communicates with the greater sac through a small vertical opening known as

Answer 22

epiploic foramen

*inferior to the liver, superior to the first part of the duodenum, IVC is posterior, portal vein anterior

Question 23

Fluid will accumulate in this area when patient is lying supine

Answer 23

Lowest parts of the body; pelvis and lateral flanks (gutters), should be examined for pathologic collections of fluid

Question 24

Gastrosplenic ligament

Answer 24

Left lateral extension of the greater omentum
Connects the gastric greater curvature to the superior splenic hilum
Forms a portion of the left lateral border of the lesser sac

Question 25

Splenorenal Ligament

Answer 25

Formed by the posterior reflection of the peritoneum of the spleen
Passes inferiorly to overlie the left kidney
Forms the posterior portion of the left lateral border of the lesser sac
Separates the lesser sac from the renosplenic recess

Question 26

Lesser Omental Bursa

Answer 26

Subdivided into a larger lateroinferior recess and a smaller mediosuperior recess by the gastropancreatic folds, which are produced by the left gastric and hepatic arteries
Superior recess of the bursa surrounds the anterior, medial, and posterior surfaces of the caudate lobe, making the caudate a lesser sac structure.
Lesser sac collections may extend a considerable distance below the plane of the pancreas by inferiorly displacing the transverse mesocolon or extending into the inferior recess of the greater omentum.

Question 27

Attachments of the peritoneum to the abdominal walls and organs help determine the way abnormal collections of fluid within the peritoneal cavity can collect or move.
