Esophagus
What is Esophagitis?
 Inflammatory changes to the
lining of the esophagus
(squamous epithelium)
Esophagitis Symptoms:
 Dysphagia
 Chest Pain
 Odynophagia
Causes:
 GERD (#1)
 Radiation
 Pills
 Caustic Ingestion
 Eosinophilic Infiltration
 Infection
Diagnostic Tests:
 Gold Standard: Endoscopy
 Bravo Study: Ambulatory
Esophageal pH
Infectious Esophagitis:
 THINK Immunocompromised!
Agents that can cause esophagitis due to
mucosal injury:
 Bisphosphanates
 Aspirin
 Iron salts
 NSAID’s
 Potassium chloride tablets
 Quinidine
 Tetracycline
There are various scales available to
quantify esophagitis severity. The
Hetzel-Dent scale utilizes a rating of 0 to
4, with 0 indicating no abnormalities and
grade 4 indicating deep peptic
ulcerations or confluent erosions
involving more than 50% of the mucosal
surface of the distal 5 cm of esophageal
squamous mucosa
CMV (Chemo/HIV)
 Ganciclovir (5mg/kg IV q 12
hours x 3-6 weeks)

Candida
 Fluconazole 100mg/d P.O. x 1421 days
 Suspect in patients w/ DM or
recent steroid or ABX treatment

Herpetic
 Acyclovir 400mg 5x daily for 10
days
 Famciclovir 500mg BID or
Valacyclovir 500mg BID x 10 days

Eosinophilic Esophagitis:
 Affects children to adults 20-40
y.o
 Males > females (3:1)
 History of allergies, eczema,
asthma or GERD is common
 “Feline esophagus” on EGD
 Often causes solid food dysphagia
due to esophagitis and
Trachealisation – “Feline Esophagus”
dysmotility
 CBC w/ diff. reveals eosinophilia –
systemic response to something
allergic
 Consider checking tTG for celiac
disease and consider food allergy
testing
 Treat acid suppression
aggressively with PPI b.i.d. For 68 wks and may consider
Montelukast (Singulair) 10mg
daily or Budesonide susp 1mg
B.I.D.
Achalasia:
 Idiopathic motility disorder
involving loss of peristalsis in the
distal 2/3 of smooth muscle and
impaired relaxation of LES.
 Likely the result of neuronal
abnormalities
 Dysphagia (solids & liquids),
Chest Pain, Weight loss
 Age 25 and greater
 Also consider Scleroderma or late
stage Chagas’ disease (South
American Trypanosomiasis)
Esophageal Varices:
 Dilated submucosal veins that
develop in patients with
underlying Portal Hypertension /
Cirrhosis and may result in
serious upper GI bleeding in 1/3
of patients.
 Usually occurs in distal 5 cm of
esophagus
 Higher mortality rate than any
other source of UGI bleeding.
 Identified via upper endoscopy
 Actively Bleeding Treatment =
ABC’s, page GI or Surgery stat
Management:
 Emergency stabilization (fluids
IVs etc)
 Treat underlying coagulopathy (if
present)
 Endoscopy with banding or
injection sclerotherapy
 Balloon tamponade (if
hemorrhage is too vigorous)
Mallory-Weiss Tear:
 Non-penetrating mucosal tear at
the GE junction caused by
retropulsion of the gastric cardia
into the chest during repeated
vomiting/retching
 ~ 5% of GI bleeds
 Small, fresh hematemesis
 Common in young adults or those
with history of ETOH abuse
 Diagnosis is confirmed
endoscopically (EGD)
Boerhaave’s Syndrome:
 Caused by a sudden increase in
intraesophageal pressure +
negative intrathoracic pressure
caused by straining or vomiting.
 Tear most often occurs @ left
posterolateral aspect of the distal
esophagus and can extend several
centimeters.
 Often associated with alcoholism
or hx. of peptic ulcer disease
 Can lead to Mediastinitis
GERD:
 Also known as Pyrosis or old
fashioned “heartburn”
 Refers to backflow of gastric acid
and/or duodenal contents (bile
acid) into the esophagus and past
the LES (lower esophageal
sphincter) without associated
belching or vomiting.
 Affects 20% of adults who report
at least weekly episodes, 10% of
adults report daily heartburn.
Symptoms:
 History of vomiting or retching
followed by acute, severe
retrosternal chest and upper
abdominal pain.
 Odynophagia
 Fever
 Cyanosis
 Shock
Pathophysiology:
1. Impaired acid neutralization by
saliva and HCO3
2. Impaired esophageal motility
3. LES (inappropriate relaxation)
4. Hiatal hernia
5. Delayed gastric emptying
(Gastroparesis)
Typical (Esophageal) Clinical
Presentation:
 Heartburn *classic*
 Bitter taste in the throat
 Acid regurgitation
Risk Factors:
 Obesity
 Delayed gastric emptying
 Pregnancy
 Systemic sclerosis
 Hiatal hernia
 Recumbency
 Smoking
 Alcohol use
 Medication such as CCB’s,
nitrates, Theophylline
 Consuming large meals (within 3
hours before bedtime) – one of
the main things that will help
with nocturnal reflux
 Wearing tight belts
 Foods: chocolate, coffee,
peppermint, or fatty food, garlic



Dysphagia
Odynophagia
Waterbrash
Atypical (Supraesophageal)
Presentation:
 Chest pain
 Laryngitis (Hoarseness)
 Asthma
 Sinusitis
 Chronic cough
 Aspiration pneumonia
 Tooth decay
 Recurrent sore throat
 Frequent throat clearing
 Globus sensation
Treatment:
Antacids (Tums, Rolaids)  neutralize
secreted HCl
H2-receptor antagonists (H2RAs) 
block the histamine receptor,
interfering with one of
the stimulation pathways
Proton pump inhibitors (PPIs)  block
acid at its source in the proton pump of
the parietal cell. (1st Line)
 Omeprazole (Prilosec) 20 mg
 Lansoprazole (Prevacid) 15 to 30
mg
 Rabeprozole (Aciphex) 20mg
 Pantoprozole (Protonix) 40mg
 Esomeprazole Magnesium
(Nexium) 40mg

Omeprazole w/Sodium Bicarb
(Zegerid) 40mg
 Dexlansoprazole (Dexilant) 60mg
Side Effects of PPI’s: HA, diarrhea,
nausea
Prokinetic drugs (Zelnorm, Reglan)
Antireflux surgery (Nissen
Fundoplication)
Esophagitis secondary to GERD:
 Severe Reflux from GERD
(incompetent LES) can lead to
esophagitis.
Diagnostic Histology:
 Intraepithelial Eosinophils
 The severity of symptoms is not
related to the degree of histologic
esophagitis
Consequences:
 bleeding, stricture, Barrett
esophagus
Treatment: Lifestyle modification
 elevate head of bed, no bedtime
snacks
 no smoking/alcohol
 decrease meal size and fat intake
 avoid caffeine (chocolate, coffee,
tea, cola) peppermint, citrus fruit
 Medications – antacids, H2
receptor blockers, proton pump
inhibitors
Barrett’s Esophagus:
 A self-protective mechanism by
which squamous epithelium in
the distal esophagus is replaced
by columnar epithelium (gastric).
 3 types of gastric columnar
epithelium, **Intestinal
metaplasia is the type that
increases the risk of
adenocarcinoma.
 Secondary to chronic refluxinduced injury – compensation by
the body but this causes a lot of
cellular turnover
 Affects ~ 10,000 people per year
in U.S.
 5 year survival rate < 15% if you
have adenocarcinoma
 Pay attention to GERD complaints
in old, white males with truncal
obesity. (Sutton’s Law)
“Tongue” of Barrett’s
Treatment:
 long-term PPI therapy and
adherence to anti-reflux
measures
 Advised to have repeat
endoscopic surveillance at 2 to 3
year intervals
Incidence of Barrett’s evolving into
esophageal adenocarcinoma is 2 in 200.
Squamous Cell Esophageal Cancer:
 Blacks > whites
 Most prevalent worldwide
 Associated with:
 ETOH
 Tobacco abuse
 Human Papilloma Virus
 > 50% involve distal third of
esophagus
Overall 5- year survival rate is < 15% for
either form of Esophageal Cancer
Adenocarcinoma Esophageal Cancer:
 Prominent in whites
 Incidence rising
 Associated with Obesity
 Most cases arise from Barrett’s
changes and chronic GERD
 Involves distal third of esophagus
Overall 5- year survival rate is < 15% for
either form of Esophageal Cancer
More Nodular:
More Spread out:
Esophageal Web:
 A thin, diaphragm-like membrane
of squamous mucosa
 Mid to upper esophagus
 May be multiple
 Congenital or may be related to
Plummer – Vinson Syndrome
Plummer-Vinson Syndrome:
 Predominately in Caucasians
 Female > male; 40-70 years old
Esophageal “Schatzki Rings”
 Smooth, circumferential and thin
mucosal structures found at the
GE junction (distal).
 Lead to dysphagia
 Strongly associated with Hiatal
Hernias
 Suspected secondary to GERD
 Treatment = Esophageal Dilation
Esophageal Strictures:
 Most found in mid to distal
esophagus
 Majority result from chronic
inflammation and GERD
 Usually benign
 Can be associated with Barrett’s
Esophagus
 May also be caused by burns
 Pills that got stuck and
disintegrated the tissue
Predominant findings are dysphagia
with a history of iron-deficiency anemia.
Treatment: Esophageal Dilation
Balloon Method:

Maloney-Dilator Method:
Zenker’s Diverticulum:
 Protrusion of pharyngeal mucosa
@ PE junction (posterior
protrusion most common).
 Caused by loss of elasticity of UES
 Usually older patients
Symptoms:
 Halitosis
 Dysphagia
 Nocturnal Choking
Diagnosis: Barium Swallow
Tx: Surgery

Benign Esophageal Tumor:
Leiomyoma
 The most common
 Submucosal, nodular lesions
 Most are asymptomatic, although
larger lesions can cause
dysphagia.
 Endoscopic ultrasonography** is
test of choice because endoscopic
biopsies are generally
Stomach
Peptic Ulcer Disease:
 Include both Gastric and
Duodenal ulcers
 ~ 10% of adults develop PUD in
their lifetime
 Epigastric Pain (dyspepsia) often
described as gnawing, dull,
“hunger-like” discomfort.
 Most common cause of Upper GI
bleeding
Duodenal Ulcers
 5x more common, younger
patients
 Pain relieved with food or
antacids, recurs 2-4 hours after a
meal, or a strong nocturnal
component
(3) major causes :
 NSAIDS – inhibit prostaglandin
synthesis. Prostaglandins are
known to increase mucosal blood
flow, increase bicarb and mucous
secretion and stimulate mucosal
repair. Aspirin is the most
ulcerogenic NSAID (beware of BC,
Goody’s powders and Alkaseltzer).
 H. pylori – gram neg. bacillus that
resides in the mucous gel coating
the epithelial cells of the stomach.
Suspected to cause a defect in
protective barrier that can then
lead to chronic gastritis and ulcer
formation.
 Zollinger-Ellison (ZE) syndrome –
benign gastrin-secreting tumor
Gastric Ulcers
 more common in ages 55-70 ,
high association with cancer
 Pain aggravated by food and
associated with weight loss and
“fear of eating”
 Associated symptoms: Nausea,
Anorexia, Abdominal bloating,
vomiting, melena, weight loss,
hematemesis
usually located in the pancreas or
duodenal wall that results in
uninhibited secretion of gastrin
(Hypersecretion) and constant
acid production. Leads to
development of peptic ulcers in
90% of patients; diarrhea is
common. < 1% of PUD is caused
by ZE syndrome, may be
associated with MEN type 1
Complications: Perforation
Diagnosis:
 Upper Endoscopy with biopsy is
diagnostic test of choice.
 CBC, BUN if suspected GI
bleeding.
 H.pylori serology gives limited
information for active
involvement of H.pylori. Need
gastric biopsy to confirm active
infection.
 Consider checking a fasting
serum Gastrin level if peptic
disease is persistent (to r/o ZES).
Need to stop PPI therapy before
testing.
Management:
 Pharmacotherapy is directed at
reduction of acid secretion,
preserving mucosal defenses, and
eradication of H.pylori infection.
 Proton pump inhibitors are
currently the treatment of choice
for PUD, given their high safety
and efficacy profile.
 Combination antibiotic regimens
with PPI are most effective in
eradicating H.pylori.
 Regular, well balanced diets with
elimination of caffeine, sodas,
acidic foods, NSAID’s, ETOH and
smoking.
Gastritis:
 superficial inflammation and
erosions of gastric mucosa
without penetration into the
submucosa or muscularis.
 Patients are usually
asymptomatic but can progress to
dyspepsia, anorexia, nausea and
vomiting.
 Accounts for < 5% of GI bleeds.

attributable to improved diet and
refrigeration (has eliminated the
need for salting, smoking,
preserved foods.)
Commonly associated with:

liver function tests may signal
compression of the pancreatic
portion of the bile duct by edema,
fibrosis, or tumor development.
