- Ptyalism
1
Q

- Esophageal diverticula
2
Q
What causes regurg secondary to esophagitis?
A
- Doxycycline in cats
- ET tubes
- FB
- Ongoing vomiting
- Chronic reflux (GERD)
- Recent Anesthesia
- Neoplasia
3
Q
Consequences of esophagitis?
A
- Stricture
- Pain
- Esophageal dysmotility
- Lower esophageal dysfunction
- Megaesophagus
4
Q
How to treat esophagitis?
A
- Nutrition with NG or gastric tube
- Sucralfate
- Analgesics
- PPI like Omeprazole only if gastroesophageal reflux is present

5
Q
What are acquired causes of megaesophagus?

6
Q
Tx of megaesophagus?
A
- Upright feedings
- Feeding tubes
- Pyridostigmine
7
Q
What GI medication is contraindicated with megaesophagus?
A
Metoclopramide / Cisapride (prokinetics)
tightens lower esophageal sphincter and will worsen reflux
8

A
- Balloon dilation
13
Q
CS of hiatal hernia?
A
- Intermittent regurg
- Ptyalism
- Vomiting
- Worse after exercise
- Brachycephalics overrepresented
- Sometimes no CS
14
Q
How to diagnose hiatal hernia?
A
- Swallow study but AFTER rads to R/O megaesophagus
