Small intestinal diseases Pt. 2 Flashcards
in inguinal hernia, foals have firm, swollen testicle while adults develop soft fluctuant swelling in the inguinal region t/f
F - baliktad. foals = soft, adult = firm
Inguinal hernia (tx for foals): If vaginal tunic ruptures, then emergency ___ and ____ of external inguinal ring indicated
reduction and imbrication
(manual reduction)
Inguinal hernia (tx for adults):
Attempts at manual reduction may rupture the bowel T/F
Testicle on affected side is treated with topical NSAIDs T/F
T
F - removed dapat
inguinal hernia can be heritable in foals (recommended to castrate) and recur in adults T/F
T
Foreign body (e.g.. rubber fencing)
Bedding (e.g.. corn cobs)
Coastal Bermuda grass hay
what does this result to?
ileal impactions
signalment of ileal impactions
Arabian geldings
Ileal impactions rarely respond to medical management with slow deterioration of physical parameters t/f
f- frequently
Ileal impactions rarely respond to medical management with slow deterioration of physical parameters t/f
f- frequently
ileal hypertrophy is idiopathic T/F?
T
Hypertrophy of the muscle layers of the ileum
Secondary luminal narrowing
Secondary partial obstruction
Ileal hypertrophy
clinical signs of ileal hypertrophy includes acute colic with vague signs of weight loss and lethargy T/F
F - intermitten instead ofacute
2 surgical procedures performed for ileal hypertrophy
ileal myotomy
ileal bypass
match prognosis to the dz
1. ileal hypertrophy
2. mesenteric defect
3. small intestinal neoplasia
A. Poor to good with surgery
;Inverse proportional to duration and severity of disease; Inverse proportion with age
B. Grave—euthanasia recommended
C. Fair with surgery
1C, 2A, 3B
Post-operative ileus
Peritonitis
Stump abscess
Adhesions
Chronic recurrent colic
these complications is a result of?
ileal hypertrophy
obesity is a contributing factor in this condition and is commonly seen in horses older than 9 y.o.
PEDUNCULATED LIPOMA
in pedunculated lipoma, 2 clinical signs can be observed
Acute, severe violent pain
Hypovolemic shock
in diagosing pedunc lipoma, what can u see if you use ultz and rec?
rec: distended loops of small intestine
ultz: distended loops + mural edema, ileus
pedunc lipoma complications
Post-operative ileus (intu, small intestine volv, inguinal hernia, epi, mesenteric defect)
Post-operative adhesions (epiploic foramen herniation, ascarid impact, small intestine volv, inguinal hernia, mesenteric defect)
Abdominal trauma
Congenital defects
Mesodiverticular band (jejunum)
Strangulation occurs as a loop of bowel passes through the rent and becomes trapped
Mesentery becomes taught and strangulates trapped bowel segment
what disease does this lead to?
mesenteric defect
surgical procedures indicated for mesenteric defect
resection and
anastomosis
surgical procedures indicated for mesenteric defect
resection and
anastomosis
how do you diagnose mesentericc defect?
+ gastric reflux (same w/ ascarid impaction, small intestine volv [copius], pedunc lip [copius], epilo
Previous abdominal surgery (colic, castration)
Small intestinal distension or ischemia
Peritonitis or abdominal foreign body
adhesions
adhesions are capable of creating obstructions within 5-7 days and is well formed by 14 days t/f
F - well formed 5-7 days, obstruct 14
Granulomatous enteritis
Eosinophilic gastroenteritis
Alimentary lymphosarcoma
SMALL INTESTINAL NEOPLASIA
Progressive weight loss
Hypoalbuminemia
Chronic, intermittent , mild colic
Anemia of chronic disease
+ Immune mediated skin lesions
SMALL INTESTINAL NEOPLASIA
small intestinal neoplasia-diagnosis: rectal. what should you find/will find?
mesenteric lymphadenopathy, thickened bowel, + abdominal mass
small intestinal neoplasia-diagnosis: ultz. what should you find/will find?
thickened bowel wall
small intestinal neoplasia-diagnosis: laparoscopy. what should you find/will find?
exploratory, lymph node biopsy
how do you treat small int. neoplasia
Resection of affected intestine (not curative)
Euthanasia
