A

incoordination between cricophyarngeus m. and swallowing reflex

seen in young dogs; congenital

dx via barium study
tx: surgery - cut the cricopharyngeal muscle

17
Q
pharyngeal dysphagia/dysfunction
etiology
CS
dx
tx
A

etiology: acquired - inability to form food bolus at base of tonge and propel down esophagus (CN 9 & 10)

CS: seen in older animals, regurgitation during swallowing

dx: barium study
tx: treat underlying myasthenia gravis

18
Q

what is an important factor in determining location of esophageal weakness?

A

the presence or absence of dysphagia with regurgitation.

if there is dysphagia - that localizes the dysfunction to the level of the oral, pharyngeal or cricophyarngeal region

if there is NO dysphagia, that localizes the issue to general esophageal dysfunction (obstruction or muscle weakness)

19
Q

what treatment is available for congenital esophgeal weakness and megaesophagus?

A

there is no definitive treatment but supportive care includes:

  • dietary modification: small and frequent meals
  • elevated feeding
  • gastrotomy tubes
20
Q

what are the clincal signs of acquired esophgeal weakness and megaesophagus?

A

CS: regurgitation, cough, weight loss, excessive drooling

21
Q

how do you dx acquired esophgeal weakness and megaesophagus?

A
  • thoracic rads
  • confirm megaesophagus via ACh receptor antibody titer
  • hypothyroidism and addison’s can also be uncommon causes
22
Q

pathophys of myasthenia gravis

A

Ab to nicotinic Ach receptors bind at the NMJ and prevent activation of skeletal muscle.

23
Q

how can you diagnose acquired myasthenia gravis?

A

tensilon test - give endrophonium and they will be able to move normally for like 10 seconds

24
Q

how do you treat myasthenia gravis?

A

pyridostigmine and neostigmine

25
Q

what meds can cause esophagitis in cats?

A

doxy and tetracycline

26
Q

what is the etiology and clinical features of esophagitis?

how do you dx it?

A

reflux, persistent vomiting, regurge, drooling

dx = esophagoscopy

27
Q

how do you treat esophagitis?

A
  1. decrease acidity of stomch: famotidine (H2 antagonist) and omeprazole
  2. prevent reflux: metoclopramide (increases LES tone), cisapride
  3. esophageal protectants: sucralfate
  4. Abx for anaerobes: amoxicillin, clindamycin
28
Q

etiology of hiatal hernia: sliding and peri-esophageal

A

sliding: cranial displacement of esophagus and stomach into mediastinum thru hiatus

29
Q

hiatal hernia: CS, dx and tx

A

CS: intermittent reflux esophagitis (regurge, vomiting, ptyalism)

dx: rads while placing pressure on abdomen
tx: medical: famotidine (H2 antagonist to decrease acidity), sucralfate (mucosal protectant), cisapride/metoclopramide (increase LES tone).
tx: sx: diaphragmatic crural apposition, esophagopexy, gastropexy

30
