Gastroenterology Flashcards
1
Q
___________ is a protrusion on the upper part of the stomach into the chest, generally caused by obesity weakening the diaphragm. It is associated with heartburn, chest pain, and dysphagia; symptoms can be indistinguishable from GERD.
A
Hiatal Hernia
2
Q
How would you diagnose Hiatal Hernia?
A
Endoscopy or Barium Studies
3

This is the best initial therapy for Hiatal Hernia.
A
Weight loss and PPIs
4
Q
These are alarm symptoms that indicates Endoscopy for Hiatal Hernia.
A
Weight loss
Blood in stool
Anemia
5
Q
This is the inability of the lower esophageal sphincter (LES) to relax due to a loss of the nerve plexus within the lower esophagus. The etiology is not clear. There is aperistalsis of the esophageal body.
A
Achalasia
6
Q
The patient is usually young (under 50), progressive dysphagia to both solids and liquids at the same time. There is no association with alcohol and tobacco use. What is the most likely diagnosis?
A
Achalasia
7

A
Schatzki Ring
19
Q
How would you treat Schatzki Ring?
A
Pneumatic dilation in an endoscopic procedure

A
Plummer-Vinson syndrome
21
Q
How would you treat Plummer-Vinson syndrome?
A
Iron replacement
22
Q
This is an outpocketing of the posterior pharyngeal constrictor muscles. There is dysphagia, halitosis, and regurgitation of food particles. Some patients suffer from aspiration pneumonia when the contents of the diverticulum end up in the lung. What is the most likely diagnosis?
A
Zenker diverticulum
23
Q
How would you diagnose and treat Zenker diverticulum?
A
Barium Studies and Surgery Repair
24
Q
What procedures are dangerous for people with Zenker diverticulum?
A
Nasogastric tube placement or upper endoscopy

This presents with upper gastrointestinal bleeding after prolonged or severe vomiting or retching. Repeated retching is followed by hematemesis of bright red blood, or by black stool. It does NOT present with dysphagia. What is the most likely diagnosis?
Mallory-Weiss Tear
26
A 44-year-old woman comes to see you because of pain in her epigastric area for the last several months. She denies nausea, vomiting, weight loss, or blood in her stool. On physical examination, you find no abnormalities.
What is the most likely diagnosis?
a. Duodenal ulcer disease
b. Gastric ulcer disease
c. Gastritis
d. Pancreatitis
e. Non-ulcer dyspepsia
f. Pancreatic cancer

Gastric Ulcer
28
If patient presents with epigastric pain and is associated with pain that is better with food, what is the most likely diagnosis?
Duodenal Ulcer
29
If patient presents with epigastric pain and is associated with weight loss, what is the most likely diagnosis?
Cancer, Gastric Ulcer
30

This is the only diagnostic test to truly understand the etiology of epigastric pain from ulcer disease.
Endoscopy
34
This is always a best initial therapy for epigastric pain.
PPIs
35
This is the inappropriate relaxation of the lower esophageal sphincter, resulting in acid contents of the stomach coming up into the esophagus. Its symptoms are worsened by nicotine, alcohol, chocolate, peppermint, late-night meals, and obesity.
GERD
36
A 42-year-old man comes to the office with several weeks of epigastric pain radiating up under his chest which becomes worse after lying flat for an hour. He also has a "brackish" taste in his mouth and a sore throat.
What is the most appropriate next step in the management of this patient?
a. Ranitidine
b. Liquid antacid
c. Lansoprazole
d. Endoscopy
e. Barium swallow
f. 24-hour pH monitoring
C. Lansoprazole is a PPI that should be used to control symptoms of GERD. When the diagnosis is very clear (such as in this case), with epigastric pain going under the sternum, bad taste, and sore throat, confirmatory testing is not necessary.
37
If patient with GERD is not responsive to medical therapy, what can you consider for treatment?
Nissen fundoplication
Endocinch
Local heat or radiation of LES
38
This disease occurs due to long-standing (at least 5 years) GERD and leads in changes in the lower esophagus with columnar metaplasia.
Barrett Esophagus
39
This is the only way to be certain of the presence of Barrett Esophagus.
Biopsy
40

49
This is the second most common cause of Peptic Ulcer Disease?
NSAIDs
50
This is the most accurate test for PUD.
Upper endoscopy
51
If the cause of PUD is H. Pylori, this is the best initial therapy.
PPI combined with Clarithromycin and Amoxicillin
52
In PUD that does not respond to initial therapy, what antibiotics can you use as an alternate?
Metronidazole and Tetracycline
53
A 56-year-old woman comes to the clinic because her symptoms of epigastric pain from an endoscopically confirmed duodenal ulcer have not responded to several weeks of a PPI, clarithromycin, and amoxicillin.
What is the most appropriate next step in the management of this patient?
a. Refer for surgery
b. Switch the PPI to ranitidine.
c. Abdominal CT scan
d. Capsule endoscopy
e. Urea breath testing
f. Vagotomy
g. Add sucralfate
E. If there is no response to DU therapy with PPIs, clarithromycin, and amoxicillin, the first thought should be antibiotic resistance of the organism. Persistent H. Pylori infection can be detected with several methods such as urea breath testing, stool antigen detection, or a repeat endoscopy for biopsy. It would be very hard to choose between these, and that is why they are not all given as choices in this question.
54
Which one of the two types of PUD has a higher chance of evolving to cancer?
Gastric Ulcer
55
This is a patient with large (>1-2 cm) ulcers, recurrent H. Pylori infection, ulcers usually found in distal part of duodenum, and usually occurs in multiple. What is the most likely diagnosis?

56
What is the most accurate diagnostic test for Zollinger-Ellison Syndrome once endoscopy confirms presence of ulcer?
- High gastrin levels off antisecretory therapy (PPIs or H2 blockers) with high gastric acidity
- High gastrin levels despite a high gastric acid output
- Persistent high gastrin levels despite injecting secretin
57
This is associated with a massive increase in the number of somatostatin receptors in the abdomen.
Gastrinoma
58
A 64-year-old patient with diabetes for 20 years comes to the office with several months of abdominal fullness, intermittent nausea, constipation, and a sense of "bloating". On physical examination, a "splash" is heard over the stomach on auscultation of the stomach when moving the patient.
What is the most appropriate next step in the management of this patient?
a. Abdominal CT Scan
b. Colonoscopy
c. Erythromycin
d. Upper endoscopy
e. Nuclear gastric emptying study
C. When the diagnosis of diabetic gastroparesis seems clear, there is no need to do diagnostic testing unless there is a failure of therapy. Erythromycin and metoclopramide increase gastrointestinal motility. The most accurate test for diabetic gastroparesis is the nuclear gastric emptying study, although it is rarely needed.
59
A 69-year-old woman comes to the emergency department with multiple red/black stools over the last day. Her past medical history is significant for aortic stenosis. Her pulse is 115 per minute and her blood pressure is 94/62 mm Hg. The physical examination is otherwise normal.
What is the most appropriate nest step in the management of this patient?
a. Colonoscopy
b. Nasogastric tube placement
c. Upper endoscopy
d. Bolus of normal saline
e. CBC
f. Bolus of 5% dextrose in water
g. Consult gastroenterology
h. Check for orthostasis
D. The precise etiology of severe GI bleeding is not as important as a fluid resuscitation. There is no point in checking for orthostasis with the person's systolic blood pressure under 100 mm Hg or when there is tachycardia at rest. Endoscopy should be performed, but it is not as important to do first as fluid resuscitation. When blood pressure is low, normal saline (NS) or Ringer lactate are better fluids to give than 5% dextrose in water (D5W). D5W does not stay in the vascular space to raise blood pressure as well as NS.

68
When will you give Fresh Frozen Plasma in a patient with GI bleeding?
if the PT or INR is elevated and active bleeding is occurring
69
When will you transfuse in a patient with GI bleeding?
when count is below 50,000 and there is bleeding
70

The stool C. diff toxin is positive and he is started on metronidazole, which leads to resolution of diarrhea over a few days. Two weeks later the diarrhea recurs and the C. diff toxin is again positive.
What is the most appropriate next step in the management of this patient?
a. Retreat with metronidazole orally
b. Use vancomycin orally
c. Sigmoidoscopy and treat only if pseudomembranes are found.
d. Intravenous metronidazole
e. Wait for stool culture
d. Intravenous vancomycin

a. Colonoscopy
b. Sigmoidoscopy
c. Fecal occult blood testing (FOBT)
d. Barium enema
e. Virtual colonoscopy with CT scanning
f. Capsule endoscopy
A. Since 40% of colon cancer occurs proximal to the rectum and sigmoid colon, sigmoidoscopy is not really sensitive in detecting lesions as colonoscopy. Barium studies, CT colonoscopy, and capsule endoscopy do not allow for biopsy. FOBT has more false positives and false negatives than colonoscopy. In addition, a positive FOBT must be followed up with colonoscopy.
103
How do you scare someone with a family history of colon cancer?
Single family member: begin 10 years earlier than the age at which the family member developed their cancer or age 40, whichever is younger. Repeat the scope every 5 years if the family member is under age 60
Three family members, 2 generations, 1 premature (before 50): Hereditary Nonpolyposis Colon Cancer Syndrome comprises these factors. Start screening at age 25 with colonoscopy every 1 to 2 years
Familial adenomatous polyposis (FAP): Start screening at age 12 every year
Previous adenomatous polyp: Patient should have a colonoscopy every 3 to 5 years
Previous history of colon cancer: Patient should have colonoscopy at 1 year after resection, then at 3 years, then every 5 years

Which of the following is associated with the worst prognosis in pancreatitis?
a. Elevated amylase
b. Elevated lipase
c. Intensity over the pain
d. Low calcium
e. C-reactive protein (CRP) rising
D. Severe pancreatic damage decreases lipase production and release leading to fat malabsorption in the gut. Calcium binds with fat (saponifies) in the bowel, leading to calcium malabsorption. Although amylase and lipase are elevated in pancreatitis, there is no correlation between the height of these enzyme levels and disease severity.
111
What is the best initial test for Acute Pancreatitis?
Amylase and Lipase
112
What is the most specific test for Acute Pancreatitis?
CT Scan (Abdominal CT Scan is always performed with IV and oral contrast to better define and outline abdominal structures)
113

Alpha 1-Antitrypsin Deficiency
125
What is the treatment for Alpha 1-Antitrypsin Deficiency?
Replace the enzyme
126
This is a genetic disorder leading to overproduction of iron in the duodenum. The mutation is the C282y gene. Men presents earlier than women because menstruation delays the onset of liver fibrosis and cirrhosis. What is the most likely diagnosis?
Hemochromatosis
127
What is the best initial test for Hemochromatosis?
Iron studies that show:
- Increased serum iron and ferritin
- Decreased iron binding capacity
128
What is the most accurate test for Hemochromatosis?
Liver biopsy for increased iron
129
A 54-year-old man has been evaluated in the office for fatigue, erectile dysfunction, and skin darkening. He is found to have transferrin saturation (iron divided by TIBC) above 50%. His AST is 2 times the upper limit of normal.
What would you do next to confirm the diagnosis?
a. Echocardiography
b. Glucose level
c. Abdominal MRI and HFE (C282y) gene testing.
d. Liver biopsy
e. Prussian blue stain of the bone marrow
f. Deferoxamine
g. Deferasirox
C. MRI will show increased iron deposition in the liver. An abnormal MRI combined with an abnormal genetic test for hemochromatosis can spare the patient the need for liver biopsy. There is an association with diabetes; however, glucose levels will not confirm a diagnosis of hemochromatosis. Prussian blue is the stain of blood cells for iron. Prussian blue is also used to diagnose sideroblastic anemia.
Iron chelation therapy is used in hemochromatosis for those who:
1. Cannot be managed with phlebotomy
2. Are anemic and have hemochromatosis from overtransfusion such as thalassemia
Deferoxamine, deferasirox, or deferipone should not be started until the diagnosis is confirmed. Deferasirox and deferipone are huge breakthrough medications because they are effective orally. Deferoxamine has to be given lifelong by injection.
