esophagus Flashcards
what disorder is seen with “birds beak” on CXR
achalasia
define reflux esophagitis
- inflammation of esophagus caused by GERD (LES relaxation) or hiatal hernia
sx: chest pain, dysphagia, odynophagia
-can lead to hemorrhagic esophagitis
infectious esophagitis RF and key features
- neutrophils are present
- RF: immunocompromised, diabetes, systemic steroids, radiation, abx
- pathogens:
1. candida: yellow white plaque on mucosa
2. HSV: multiple small DEEP ulcers
3. CMV: 1+ large SHALLOW ulcers
diffuse vs limited scleroderma antibodies
diffuse: Scl-70 Ab, and anti- topiosomerase Ab
limited (CREST syndrome): anti-centromere Ab
what is Killians triangle
area of muscular weakness around the level of the upper esophageal sphincter in which Zenkers Diverticulum protrude
(cricopharyngeus M. and inferior constrictor M.s)
define hemorrhagic esophagitis
- inflammation of the esophagus that presents with hematemesis
- RF: GERD (dyspepsia, water brush), reflux esophagitis
- sx: dysphagia, odynophagia, sharp chest pain, at night and early morning
risk factors of esophageal variceal bleed
- size of varices (>5mm)
- red wale marks on EGD
- liver disease severity (raises hepatic venous pressure)
- active alcohol abuse
(others: hepatic venous pressure or previous bleed)
prevention by nonselective beta blockers
risk factors of esophageal adenocarcinoma
- hiatal hernia (causes GERD)
- GERD
- BARRETTS ESOPHAGUS
- obesity
(all factors related to development of chronic GERD and subsequent BARRETTS)
most common type of esophagitis
reflux esophagitis
most common diaphragmatic hernia and associated complications
sliding hiatal hernia (displacement of GEJ superiorly)
-leads to GERD–> Barretts esophagus –> increased risk of adenocarcinoma
(also but less commonly associated with reflux esophagitis–> hemorrhagic esophagitis)
esophagitis
leads to stricture sites
- it is ulcers with superficial necrosis that leads to fibrosis
- major sx: odynophagia , dysphagia (second), Chestpain (third)
what can cause acquired esophageal webs
eosinophilic esophagitis and plummer vinson syndrome
histological characteristics of Barretts esophagus
Histo: distinct mucous vacuoles that stain pale blue by H&E (hematoxylin and eosin)
-dx: EGD and biopsy
treatment risk associated with eosinophilic esophagitis
dilitation can cause PERFORATION –>hematemesis, pnuemomediastinum, subcutaneous emphysema, Hammans sign
what is Romana sign
painless peri-orbital swelling
seen in achalasia associated with Chagas Dz
pill esophagitis RF and key features
RF: NSAIDs, Potassium chloride pills, ronate, abx, injured esophagus
- EGD shows 1+ ulcers
- complications: stricture, hemorrhage, rupture
- tx: stop meds or take with 4oz water and stand for 30 minutes
characteristics of nutcracker esophagus
- esophageal dysmotility disorder caused by hypertensive peristalsis (tight contraction) of the DISTAL portion of the esophagus
- Unique features:
1. NL coordinated contractions (except at distal part there is incoordination),
2. NL relaxation of the LES,
3. high amplitude pressure on manometry, (high baseline pressure of LES)
(SX same as DES)
sx: intermittent (nonprogressive) esophageal dysphagia (solids and liquids), atypical Chest pain
characteristics of Boerhaves syndrome
- spontaneous TRANSMURAL tear at the GEJ leading to esophageal perforation
- associated with hx of retching, vommiting, alcohol
- sx: VERY SICK, PAINFUL hematemesis, shock, subcutaneous emphysema, Hammans sign
- dx: CXR (seen pneumomediastinum)
tx: NPO, Abx, stent, surgery
