Multisystem, FIBROSIS OF MANY ORGANS

High incidence of stricture, GERD, dysphagia due to wek peristalsis, heartburn Extra-GI symptoms

20
Q

Scleroderma (Diagnx/Treat)

A

Manometry
PRINCIPAL PATH is SM atrophy and gut wall FIBROSIS
Treat with PPIs

21
Q

Chemical Injury

A

Corrosive, PILL ESOPHAGITIS ( pill stuck –> inlf, NSAIDs, K supplements), reflux esophagitis
Pres: ODYNOPHAGIA, +/- dysphagia
Diagnx: H&P, +/- endoscopy
Treat: discontinue offending agent (underlying cause)

22
Q

INFX

Herpes

A
Usually immunocompromised
Pres: PAIN WITH SWALLOWING (odynophagia), dysphagia, GI bleen
Diagnx: endoscopy: PUNCHED OUT ULCERS
Hist: INTRANUCLEAR VIRAL INCLUSION
Treat: Antivirals
23
Q

INFX

Candida

A

Most frequent, also immunocompromised
Pres: Odynophagia, +/- dysphagia, or asymptomatic
Diagnx: endoscopy: WHITE PLAQUES, fibrinopurulent exudate
Hist: PSEUDOHYPHAE, budding yeast in tissue (special stains GMS, PAS)
Treat: Antifungals

24
Q

INFX

CMV

A

Immunocomprimised, usu in combo with candida
Pres: Odynoophagia, +/- dysphagia, GI bleeding
Diagnx: endoscopy: punched out ulcers in distal eso
Hist: CYTO and NUCLEOMEGALY, intraCYTOPLASMIC inclusions
Treat: antiviral

25
Q

Eosinophilic Esophagitis (cause/info/pres)

A

Caused by eosinophilic infiltrate, diffuse narrowing of esophagus, MALES,

26
Q

Eosinophilic Esophagitis (diagnx/treat)

A

Endoscopy: concentric rings, burrows, nodular plaques and exudates
Biopsy: diffuse sheet of eosinophils, frequent degranulated forms (dust, microabscesses), MID-ESOPHAGUS
Treat: TOPICAL STEROIDS (oral spray), dilation may be necessary, endoscopic removal of bolus, no response to anti-reflux tx

27
Q

Barrett’s Esophagus (cause/risks/pres)

A

consequence of GERD (F, decreased LES resting pressure, smoking obesity
Increasing in prevalence
Pres: USUALLY ASYMPTOMATIC OR HEARTBURN

28
Q

Barrett’s Esophagus (Diagnx/treat)

A

METAPLASIA (squamous–>glandular containing columnar (goblet) epithelium) this is an effort of the esophagus to protect itself rorm acid
Salmon colored patch on endoscopy
Alcian BLUE stain highlights GOBLET cells (no goblet cells in stomach)
Treat: GERD treatment, also increase screening

29
Q

Benign Strictures

A

Minority of pts with reflux eso get peptic stricture of distal eso (due to fibrosis from relfux)
PRES: SOLID FOOD DYSPHAGIA
Diagnx: EGD (biopsy to rule out cancer and tx dilation)
Treat: GERD treatment, also with EGD dilation

30
Q

Mucosal (“Schatzki”) Rings

congenital esophageal rings –> narrow lumen and cause infl (similar to benign stricture)
Pres: dysphagia

Q

Oropharynx (involved in …/phases …)

A
Swallowing (deglutition)
Normal = 600x /day
Oral phase (voluntary): biting,licking, chewing, initiation of swallow
Pharyngeal phase (involuntary): once bolus gets to posterior 1/3 of tongue, pharnyx contracts and changes shape (hyoid/larynx up and anterior), UES relaxes, soft palate elevates to close nasopharynx and protect airway
