  • ulcers
21
Q

Clin sig of cardiac junct

A

22
Q

Where does the cardiac junction sit

A

@ angle of 11th intercostal space

23
Q

List the 3 muscular layers of the stomach

A
  • inner circular
  • outer longitudinal
  • oblique (mixes food)
24
Q

Duodenum is not rectally palpable unless

A

Animal has anterior enteritis

25
Q

Clin sig of jejunum

A

26
Q

Clin sig of large intestine

A
  • impaction colic
27
Q

Which parts of the colon have 0 sacculation

A

L dorsal colon & Transverse colon

28
Q

4 anatomical predisposing factors of colic

A
  • free moving intestine (jejunum)
  • acute reductions in diameter (i.e. pelvic flexure, cecocolic junction, R dorsal/transverse colon)
  • wide mesentery
  • natural openings
29
Q

3 areas of impaction

A

1) pelvic flexure

2) cecocolic junction

3) R dorsal colon to transverse colon

30
Q

3 natural openings of abdomen

A

1) inguinal canal (jejunum)

2) Nephrosplenic lig. ( L dorsal colon & pelvic flexure)

3) Epiploic foramen (jejunum)

31
Q

Colon can become trapped over…

A

Nephrosplenic lig

32
Q

3 borders of epiploic foramen

A
  • dorsal: vena cava
  • ventral: portal vein
  • cranially: hepatoduodenal ligament
33
Q

4 non-atomical predisposing factors of colic

A
  • lipoma
  • enteroliths
  • parasites ( block cranial mesenteric a.)
  • sand
34
Q

Where to get a pulse on horses (2 sites)

A
  • facial a.
  • transverse facial a.
35
Q

Steps in a gastric reflux procedure

A

1) block false nostril

2) measure tube to 11th intercostal space

3) initiate swallowing response

36
Q

Location for abdominocentesis

(cranial to line of pleural reflection)

10 cm caudal to xiphoid cartilage on ventral midline

37
Q

All structures that may be rectally palpable

  • L kidney
  • Cd. Border of spleen
  • Dorsal and Ventral colon
    -Pelvic flexure
    -Nephrosplenic lig
  • Small colon
38
Q

Structures rectally palpable on R side

A
  • Right ventral colon

-cecum

A
  • through linea alba
40
Q

Clin sig of pelvic flexure incision

A
  • cut adjacent to pelvic flexure b/c healing process decreases diameter + plexus is present
41
Q

Why doesn’t the needle go through the abdominal wall when suturing the linea alba

A

Muscles aren’t a holding layer

42
Q

Complications of colic surgery

A
  • suture failure (hernia)
  • technical failure ( adhesions, infection)
