Q

Regarding colonoscopies and fecal occult blood tests, what are the current recommendations?

A
  • Fecal occult blood test annually starting at 50
  • Colonoscopy every 10 years from 50-75
  • Flexible sigmoidoscopy every 5 years, along with occult blood test every 3 years

If patient has FAP, the colonoscopies start at age 10-12 and they have flexible sigmoidoscopy yearly.

23
Q

However, for eosinophilic esophagitis, what is the definitive diagnostic?

Study These Flashcards
A

Biopsy: presence of abundance of eosinophils

24
Q

What medications are usual causes of pill esophagitis?

Study These Flashcards
A

NSAIDs, bisphosphonates, BB, CCB, Vitamin C

25
How to manage symptoms of pill esophagitis
- Take pills with at least 4 ounces of water | - Avoid recumbency for at least 30-60 minutes after pill ingestion
26
A sliding hiatal hernia is the MC type. Explain what happens in this type of hernia
-GE junction slides into mediastinum
27
Treatment for hiatal hernia
- PPI | - Weight loss
28
Pathophysiology of GERD
- Incompetent lower esophageal sphincter | - Transient relaxation of LES
29
Symptoms of GERD
- Heartburn (pyrosis) - Sour taste in mouth, cough, sore throat - Wheezing, chest pain, hoarseness (atypical symptoms)
30
Alarm symptoms of GERD
-Dysphagia, odynophagia, weight loss, bleeding
31
Diagnostics for GERD
- 24 hour ambulatory pH: GOLD STANDARD - Manometry: decreased LES pressure - Endoscopy: first line diagnostic test if persistent or alarm symptoms
32
Treatment for GERD
- Lifestyle modifications: elevated head of bed, avoid food in night, weight loss, no alcohol, smoking cessation - Antacids and H2 receptor antagonists (Famotidine, Cimetidine) - PPI in moderate-severe ( > 2 episodes/week) (Omeprazole) - Nissen fundoplication if refractory
33
Pathophysiology of Barrett's Esophagus
- Esophageal squamous epithelium replaced by precancerous metaplastic columnar cells from cardia of the stomach - Complication of long-standing GERD
34
MC type of esophageal carcinoma in the US MC type of esophageal carcinoma in the world
- Adenocarcinoma (distal esophagus) | - Squamous cell (mid-upper third of esophagus)
35
Risk factors for Adenocarcinoma
- Caucasian males - Barrett's Esophagus - Smoking - Obesity
36
Squamous Cell Carcinoma of the esophagus occurs ______ and is the MCC worldwide. What are the risk factors for this type of cancer?
Mid-upper third of the esophagus -African American Smoking -Alcohol
37
Symptoms of esophageal cancer
Progressive dysphagia: solid food dysphagia progressing to include fluids, odynophagia -Weight loss, anorexia, iron deficiency anemia
38
What is the diagnostic study of choice for esophageal cancer?
Upper endoscopy with biopsy
39
What diagnostic is done to stage esophageal cancer?
Endoscopic US
40
Pathophysiology of Achalasia
Loss of peristalsis and failure of relaxation of lower esophageal sphincter -Degeneration of Auerbach's Plexus
41
Symptoms of Achalasia
Dysphagia to solids and liquids at same time | -Chest pain, cough, weight loss, dehydration
42
Diagnostics for Achalasia
- Barium esophagram: bird's beak appearance of LES - Manometry: most accurate test (increased LES pressure) - Endoscopy: performed prior to starting treatment to rule out SCC
43
Treatment for Achalasia
- Decrease LES pressure: Botox injection, Nitrates - Pneumatic dilation of LES - Esophagomyomectomy (definitive)
44
Symptoms of a Zenker's Diverticulum Pathophysiology of Zenker's
- Dysphagia - Lump in neck - Choking Sensation - Halitosis (due to food retention in pouch) -Weakness at Killian's Triangle (between fibers of the cricopharyngeal muscle and lower inferior pharyngeal constrictor muscle)
45
Diagnostic for Zenker Diverticulum
- Barium Esophagram | - Upper endoscopy for surgical evaluation
46
Symptoms of Diffuse Esophageal Spasm
- Stabbing chest pain worse with hot or cold liquids or food - Not exertional pain (similar to angina though) - Dysphagia to both solids and liquids - Sensation of object stuck in throat
47
Diagnostics for DES
- Esophagram: corkscrew esophagus | - Manometry: definitive (increased premature contractions)
48
Treatment for DES
- Anti-spasmodics: CCB, Nitrates, TCA | - Botox injections, pneumatic dilation
49
Pathophysiology of Mallory Weiss Tear
Sudden rise in intra-abdominal pressure due to persistent retching or vomiting after ETOH binge
50
Symptoms of Mallory Weiss Tear
- Upper GI bleeding | - Abdominal pain, back pain, or hydrophobia
51
Diagnostic of choice for Mallory Weiss Tear
-Upper endoscopy: shows longitudinal mucosal erosions
52
Treatment for Mallory Weiss Tears
- Non-bleeding: supportive, PPIs | - Bleeding: Band ligation
53
Diagnostic of choice for Esophageal Web or Esophageal Ring
Barium Swallow (Esophagram)
54
Treatment for Esophageal Ring
Dilation
