1

Site for abscess formations

lesser sac, subphrenic, subcapular

2

Mallignant/Inflammatory Ascites

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

3

Clinical symptoms of infection

increased white blood cell count
pain
fever
warmth
palpable

4

What is Inflammatory Ascites usually linked to?

Cancer
Colisticyticis Disease Process

5

Biloma

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

6

Urachal Cyst

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)

7

Greater Omentum

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

8

Lymphocele

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)

9

Peritoneum

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

10

Sepsis

spread of infection from initial site into the bloodstream

11

Differential diagnosis for lesser sac abscess

pseudocyst
pancreatic abscess
gastric outlet obstruction
fluid-filled stomach

12

Hydatid cyst in the spleen

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

13

Candidiasis

a kind of infection
common in AIDS patients

14

Hernia

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

15

The peritoneal cavity is made up of..

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

16

Within the cavity

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

17

Parietal peritoneum

The part that lines the walls of the cavity

18

Visceral peritoneum

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

19

Lesser omentum

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

20

Greater sac

general peritoneal cavity

21

Lesser sac

Peritoneal recess posterior to the stomach
Extends to the diaphragm

22

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

epiploic foramen

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

23

Fluid will accumulate in this area when patient is lying supine

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

24

Gastrosplenic ligament

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

25

Splenorenal Ligament

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

26

Lesser Omental Bursa

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.

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.
