16
Q

External Hernia

A

DIsplacement of viscera outside abdominal cavity

17
Q

Hernial Contents

A

Displaced viscera

18
Q

Hernial Sac

A

Pouch formed by peritoneum and skin

19
Q

Hernial Ring

A

Opening through which viscera is displaced

20
Q

Eventration

A

Displaced contents not within sac, can be traumatic, leads to sepsis and venous infarct due to mesenteric compression

21
Q

Diaphragmatic Hernia

A

Liver and small intestine through diaphragm, common in cat

22
Q

Scrotal Hernia

A

Displacement of intestines through inguinal canal to scrotum, complication of castration and can lead to incarceration

23
Q

Incarceration

A

Intestines can get stuck in hernia

24
Q

Umbilical Hernia

A

Can fluctuate in size until intestine is strangulated

25
Strangulated Intestine Appearance
Infected, swollen, dark, and friable
26
Colonic Torsion
Left colon susceptible in horse, presents with colic
27
Intestinal Volvulus
Torsion along mesenteric axis, common in horse presenting with colic
28
Pedunculated Lipomas
Common in equine mesentery, stalk allows lipoma to rotate and can become mineralized, strangulating intestine
29
Intussusception
Intestine telescoping, drags and tears mesentery, leading to venous infarction, discolored, ulcerated, and hemorrhagic
30
Intussuscipiens
Outside of telescoping
31
Intussusceptum
Piece going inside
32
Intussusception Pathogenesis
Same as volvulus and torsion, can be associated with increased peristaltic activity from coccidiosis
33
Anoplocephala perfoliata
Horse tapeworm
34
Enteritis
Intestinal inflammation
35
Typhlitis
Cecum inflammation
36
Colitis
Colon inflammation
37
Proctitis
Rectum inflammation
