Esophagus, stomach, duodenum Flashcards
What is the most common cause of esophagitis
GERD
What is esophagitis
inflammation or injury to esophageal mucosa
What is the most common cause of infection of the esophagus
Fungus
What is Eosiniphilic esophagitis (EoE)
Chronic immune antigen-related esophageal disease
What is the common presentation of esophagitis
retrosternal chest pain
heart burn
odynophagia / dysphagia
What can help differentiate the subtypes of esophagitis
endoscopy and bx
What is CMV esophagitis
several large, shallow, superficial ulcerations
What is HSV esophagitis
multiple small, deep ulcerations
What does EoE esophagitis look like
white exudates/papules, red furrows, corrugated concentric rings and strictures
What medication must be avoided with esophagitis
NSAIDs
What are some complications of esophagitis
bleeding
stricture
barretts esophagus
perforation
laryngitis
aspiration pneumonia
What is gastritis
Inflammation of gastric mucosa caused by infection, drugs, stress, atrophic gastritis
How do you diagnose gastritis
endoscopy
How do you differentiate between erosive and non-erosive gastritis
based of the severity of mucosal injury
What causes gastric atrophy
result of long standing gastritis
(loss of intrinsic factors)
What is the clinical presentation of non-erosive gastritis
mostly asx but may c/o with dyspepsia
What is the treatment of non-erosive gastritis
Eradication of H.pylori
What is the most common pathogen that causes gastritis
H.Pylori
What is the most common/gold standard to diagnose H.pylori
Urea breath test
What is the treatment of H.Pylori
PPI plus 2 antibiotics
What does H.Pylori typically cause
Gastritis
PUD
Gastric adenosine-carcinoma
gastric lymphoma
What does H.Pylori put you at an increased risk for
Stomach cancer
*class 1 carcinogen
How does H.Pylori cause gastritis
Increased gastrin production which results in increased acid production predisposing to pre pyloric and duodenal ulcer
What is the best treatment for H.Pylori
PPI + Metronidazole + tetracycline + Bismuth subsalicylate x 14 days
If ulcers are present, how long does a PPI need to be used in tx of H.Pylori
4 week minimum
What is erosive gastritis
damage to mucosal defenses
*usually acute with bleeding
What are common causes of Erosive gastritis
NSAIDs
Alcohol
Stress
What is the first sign of erosive gastritis
Hematemesis or melena for 2-5 days of inciting event
What is GERD
Incompetence of LES allowing reflux of gastric contents into the esophagus = burning pain
What is the typical sx of GERD
heartburn 30-60min postprandial
What increases the risk for GERD
Weight gain
fatty food
caffeinated/carbonated drinks
alcohol
tobacco smoking
drugs/meds
Which drugs will worsen GERD
Anticholinergics
antihistamines
TCSa
CCBs
progesterone
nitrates
What are the components of Gerd
Impaired LES function
hiatal hernia
irritant effects of reflux (pH>4)
abnormal esophageal clearance
What conditions can weaken LES
hiatal hernia
pregnancy
What condition affect transit from stomach to the small intestine
diabetes
PUD
connective tissue disorders
What is the common clinical presentation of GERD
heartburn
regurgitation
dysphagia
What is heartburn
retrosternal burning discomfort located in the epigastric area.
May radiate upwards and typically occur postprandial
If GERD does not respond to empiric treatment or has longstanding symptoms, how do you work them up
Endoscopy with cytology and/or bx is test of choice
What are some complications of GERD
Barretts esophagus
esophagitis
chronic aspiration
peptic strictures
esophageal ulcers
What is the number one treatment for GERD
lifestyle modification
What are things to avoid with GERD
Eating within 3 hours of bedtime
strong stimulants for acid secrete
Certain meds
specific foods
smoking
What are some drug therapy that can be done for GERD
Antacids
H2 blockers
PPIs
What are some antireflux procedures that can be done for GERD
Laparoscopic fundoplication
bariatric surgery
esophageal strictures
what is the only complication of GERD with malignant potential
barretts esophagus
Who is Barretts esophagus typically seen in
middle age white males
what cellular changes are seen with Barretts esophagus
conversion of normal esophageal squamous epithelium into metaplastic columnar epithelium
What is the clinical presentation for Barretts esophagus
chronic history of GERD with no other specific exam finding
What are the screening guidelines for Barretts esophagus in men
> 5 years of chronic GERD with 2 additional risk factors
> 50yo, hx smoking, white ethnicity, central obesity, +fh BE
What will be seen on endoscopy with Barretts esophagus
columnas metaplasia (salmon pink tongues of mucosal tissues)
