Small Intestinal Diseases Pt. 1 Flashcards
A syndrome that produces hemorrhagic necrotizing duodenitis and jejunitis
The answer above is rarely idiopathic, can be found local, and clostridial. T/F
The answer above frequently can be differentiated from a strangulating obstruction. T/F
proximal enteritis
F - mostly idio, regional dapat
F - cannot be
proximal enteritis clinical signs include pyrexia (102-104F), anorexia, depression, mild to severe abdominal pain and laminar pain. T/F
This can be diagnosed via Large volume of alkaline gastric reflux,
rectal - large intestinal distension
ultz - mural thickening of ileus T/F
T
F sa rectal: small intestinal dapat
Normally, intestines cannot be palpated during rectal examination, but if there’s proximal enteritis, the intestine balloons → emerge as bread slices upon palpation T/F
T
In older horses, strangulation (wraps around) of jejunum occurs. It is malignant. T/F
F - benign
How do you treat proximal enteritis?
Main goal: decompression
fluids, NSAIDs, surgery, nasogastric tube
Match the prognosis per dz
1. proximal enteritis
2. intu
3. ascarid impactions
A. Grave to guarded with surgery
(Frequently debilitated from chronic infestation)
B. Guarded; 56% fatality with therapy
C. Good with surgical intervention (Inversely proportional to: Duration of time, Mural rupture, Ileus)
3A, 2C, 1B
The following are complications arising from proximal enteritis except.
A. Nephritis, DIC, Hepatitis
B. Laminitis, Thrombophlebitis
C. Intestinal perforation , Intestinal rupture
D. NOTA
C - pang intu to
Invagination of a segment of bowel and its mesentery into the lumen of an adjacent segment of bowel
Intussusception
the following are etiology of intussusception. except
A. Heavy ascarid or tape worm infestation
B. Obstruction—foreign body, hypertrophy, neoplasia
C. Enteritis or altered peristaltic motility
D. NOTA
E. AOTA
E
an animal with intu, experience chronic violent pain but occurs acutely intermittent. T/F
Intu is common in young horses T/F
F - baliktad. Acute violent, chornic intermittent
T
Intu Diagnosis
Rectal: distended loops of small intestine
Ultz: bulls eye lesion with distended T/F?
T
The following are complications arising from proximal enteritis except.
A Post-operative ileus, Peritonitis
B. Laminitis
C. Stump abscess, Adhesions
D. Recurrence Loops of small
E. AOTA
F: NOTA
E pero take note:
B. EPIPLOIC FORAMEN HERNIATION
Heavy Parascaris equorum(roundworm) infestation
Drugs that paralyze and rupture the roundworms
Ascarid impactions
non-benzimidazole(paralyze), organophosphate (rupture ascarid cuticle releasing antigenic fluid that suppresses intestinal motility)
Ascarid impactions affect middle aged to aged horses T/F
F - foal to yearling dapat
Middle to aged - EPIPLOIC FORAMEN HERNIATION
AScarid impaction hx: Acute onset of abdominal pain associated with ____ administration
antihelminthic
the ff are clinical signs of Ascarid impaction except for 2 letters:
A. Moderate to severe abdominal pain, Pendulous belly (pot belly, Rough hair coat
B. Intermittent colic with vague signs of weight loss and lethargy
C. Acute, severe, uncontrollable pain without abdominal distension
D. Poor body condition, + Harsh lungs sounds, + Nasal discharge
C - mesenteric defect
B - ileal hypertrophy
in treating ascarid impactions, 1 enterotomies is enough T/F
F- multiple dapat
The following are complications arising from ascarid impactions except: (2 letters)
A Chronic recurrent colic
B. Fatal rupture of caudal vena cava or portal vein during surgical reduction,
C. Toxic shock, Intestinal perforation , Intestinal rupture
D. Peritonitis, Intussusception, Post-operative adhesions
A -ileal hypertrophy
B -EPIPLOIC FORAMEN HERNIATION
SMALL INTESTINE VOLVULUS, Ascarid Impactions,INGUINAL HERNIA
Post-operative adhesions
Occurs when a segment of small intestine twists on its own mesentery
The mesentery continues to twist as more intestine is drawn into the volvulus thus constricting the blood supply and strangulating the bowel
SMALL INTESTINE VOLVULUS
Intestinal infarction
Severe Ascarid infestation
Intestinal incarceration
Adhesions or fibrous bands
Mesodiverticular band or Meckel’s diverticulum
the following are the etilogy of what disease?
A. Ascarid impaction
B. Small instestine voluvuls
C. Intussusception
D. Proximal enteritis
B
Small intestinal volvulus occurs in young foals (1-3 years ) which are overrepresented T/F
F - not age specific
In small intestinal volvulus, Acute, severe violent pain with abdominal distension and Hypovolemic shock occurs as clinical signs. T/F
F - WITHOUT dapat
diagnosing small intestinal volvulus includes Rapid progression of pain and shock Copious gastric reflux
T/F
T
small intestinal volvulus and proximal enteritis are diagnosed with rectal and ultz. In inguinal hernia, same din sa ultz
Rectal- small intestinal distention
Ultz - small intestinal distension, ileu
T/F?
T
Match the prognosis per dz
1. small intestinal volvulus
2. inguinal hernia
3. ileal impaction
A. Fair to good; Poor if adhesions or ileus develop post-operatively
B. Good long term
Fair if ileal bypass required
C. Grave with surgery
80% fatality rate
Rapidly fatal, often die during shipping
1C, 2A, 3B
small intetsinal volvulus,
post op ileus
sudden increase in intra-abdominal pressure
Inguinal hernia
Swelling noticed soon after foaling
Recent history of breeding
Recent history of trauma or physical exertion
This is seen in horses with?
Inguinal hernia
breeds that are susceptible in developing inguinal hernia
Breed—Standardbred, Tennessee Walking Horse, American Saddlebred, Belgian
+ older stallion and neonatal colt
