Gallstones. Right upper quadrant. Precipitated by meals, especially fatty foods. Last 30 to 60 minutes with spontaneous resolution

4

Irritable bowel syndrome suggested by what symptoms?

1. Chronic dysmotility symptoms (up loading, cramping)
2. Relieves with defecation
3. no weight loss or bleeding

5

Duodenal ulcers caused pain how long after meals? Relieved by?

2 to 5 hours after a meal. Food or antacids.

6

If food worsens gastric pain - think?

Gastric ulcer

7

Gastric cancer can present with dysphasia if? Persistent vomiting if? Early satiety it?

In the cardiac region of the stomach. Blocking the pyloric channel. Mass effect or infiltration of the stomach wall.

8

When should patients undergo endoscopy for dyspepsia?

1. Older than 45 years who present with new onset dyspepsia
2. Patients with alarm symptoms (weight-loss, recurrent vomiting, dysphasia, bleeding, anemia)
3. Symptoms have failed to respond to empiric therapy

9

In younger patients with no alarm features - strategy for dyspepsia?

Urea breath test or H. pylori antibody test

10

Problem with H. pylori antibody test?

Will remain positive for life even after successful treatment

11

Cancers associated with H. pylori?

Gastric carcinoma and gastric MALT lymphoma

12

Treatment for H. pylori?

Clarithromycin, amoxicillin and a PPI

13

Major cause of duodenal and gastric ulcers not caused by H. pylori? Mech?

NSAIDs. Inhibit prostaglandin synthesis resulting in reduced secretion of mucus and bicarb and decreased mucosal bloodflow

14

Condition that should be suspected if pt with ulcers is H. pylori negative and does not use NSAIDs? Diagnosed with?

Zollinger-Ellison syndrome. Serum gastrin levels greater than 1000

15

Free perforation into the abdominal cavity may cause?

Hemorrhage with severe onset of pain and development of Peritonitis

16

Indications for surgical intervention?

Perforation and obstruction

17

Symptoms of gastric outlet obstruction?

Persistent vomiting and weight loss with +/-
abdominal distention

18

Gastritis? Presents as? Common causes?

#Portal hypertension
#Stress (trauma, burns, sepsis, uremia)

19

Atrophic gastritis is associated with which vitamin deficiency?

B12

20

Test to diagnose erosive gastritis?

#Endoscopy to diagnose
#H pylori testing

21

H pylori testing options?

#endoscopic biopsy – most accurate/invasive
#Serology – negative test excludes infection but lacks specificity (current versus old infection?)
#Urea breath testing – positive only in activity fiction
# stool antigen – positive only in active infection

22

When to give stress ulcer prophylaxis?

#Mechanical ventilation
#head trauma
#burns
#Coagulopathy

23

Role of alcohol and tobacco in PUD?

Delay healing of ulcers (do not cause ulcers)

24

Risk of cancer into duodenal PUD? Gastric PUD?

No risk

4%

25

Patient with H. pylori gastritis treated with triple therapy. How to evaluate if treatment worked?

Treatment failure usually from?

Breath test or stool antigen

Alcohol, NSAIDs, smoking, medication noncompliance

26

Patient with confirmed gastrinoma. CT/MRI negative for metastases. Next step?

Somatostatin receptor scintigraphy (nuclear octreotide scan) + endoscopic ultrasound to further exclude metastases

(Gastrinoma associated with increased number of somatostatin receptors)

27

Treatment for diabetic gastroparesis?

Erythromycin and metoclopramide
