Esophagus & stomach Flashcards
What causes esophagitis?
Candida
CMV, HSV
What is the presentation of esophagitis?
Odynophagia or dysphagia**
Fever, lymphadenopathy
How do you dx esophagitis?
Endoscopy
Definitive = cytology/culture
How do you treat esophagitis?
Candida: Fluconazole or ketoconazole
HSV: Acyclovir
CMV: IV ganciclovir or foscarnet
What is the presentation of medical induced esophagitis?
Severe retrosternal CP
Odynophagia, dysphagia
How does corrosive esophagitis (due to ingestion of causative agent) present?
Ulceration, necrosis, perforation
What are complications of corrosive esophagitis?
Fibrosis
Stricture
Increased risk of SCC
How does neurogenic esophageal dysmotility present?
Trouble swallowing liquids & solids
Can lead to aspiration pneumo
How does Zenker’s diverticulum (an esophageal dysmotility) present?
Pouch in posterior hypopharynx above UES
Undigested food & liquid is regurgitated
How does esophageal stenosis (an esophageal dysmotility) present?
Webs, rings, malignancy
Trouble swallowing solids
What is the presentation of Schatzki’s ring?
Occurs at GE junction
Dysphagia to solids
+/- impaction of bolus
Abrupt sub-sternal discomfort
What are esophageal webs?
Mucosal fold protrudes into lumen
Intermittent dysphagia to solids
Sx seen in iron deficiency & middle-aged women (plummer vinson syndrome)
Describe achalasia
Decreased peristalsis, ineffective relaxation of LES
Dysphagia to solids & liquids
Describe esophageal spasm
Dysphagia or intermittent CP
+/- a/w eating, drinking cold liquids
Can mimic MI
Describe scleroderma of the LES
Decreased sphincter tone & peristalsis –> reflux
How do you dx achalasia?
Parrot beak on esophagram
Dilated esophagus tapering to distal obstruction
How do you dx diffuse esophageal spasm?
Barium esophagram: corkscrew
How do you treat esophageal spasm?
SM relaxants
NTG before meals & bed
Isosorbide before meals
Nifedipine before meals
What is an ADE of SM relaxants?
Hypotension
What does “CREST” stand for in scleroderma?
Calcinosis Raynauds Esophageal dysmotility Sclerodactyly Telangiectasis
How do you dx dysphagia in general?
Barium swallow
Endoscopy: to DIRECTLY see abnormalities & bx
Esophageal manometry
How do you treat esophageal dysmotility?
Strictures: if benign –> dilation, if CA –> resect
Diverticula, achalasia, stenonis: endoscopic dilation, resection, myotomy
Describe: Mallory-Weiss Tear
Causes 10% of upper GIB
Linear tear in esophageal mucosa
Usually at GE junction
What is the pathophys behind Mallory-Weiss tears?
Occurs w/ forceful vomiting/retching
Leads to hematemesis
What are RFs of Mallory-Weiss tears?
Alcohol
Hyperemesis gravidarum
How do you dx Mallory-Weiss tears?
Endoscopy
How do you treat Mallory-Weiss tears?
Epi injection to stop bleeding
Thermal coagulation
Surgery if severe
What causes esophageal varices?
Portal HTN from cirrhosis due to alcohol abuse or chronic hepatitis
Budd-Chiari syndrome (thrombosis of portal vein)
What are RFs of esophageal varices?
NSAIDs exarcerbate bleeding
How do esophageal varices present?
Painless upper GI bleed
If large bleed –> hypovolemic shock, orthostasis
Usually asx until they bleed & become life-threatening!
How do you dx esophageal varices?
Endoscopy
How do you treat esophageal varices?
Hemodynamic support
Emergent EGD: Band ligation, sclerotherapy
How do you prevent esophageal varices in pts w/ cirrhosis?
B-blockers
No alcohol
Band ligation
