GI Precision & Pearls #1 Flashcards
GERD is due to ___________. Name some typical symptoms of this condition.
What diagnostics are done for GERD. There are three. What is shown on the first? What is the GOLD standard? What is the first line if persistent or complicated?
Transient relaxation of the LES –> esophageal mucosal injury
Symptoms: Pyrosis, acid taste, etc.
Diagnostics: Esophageal manometry (shows decreased LES pressure); 24 hour ambulatory pH (GOLD STANDARD); Endoscopy (first line if complicated)
What are some atypical GERD symptoms?
Name some alarm symptoms of GERD.
Atypical: Hoarseness, wheezing, chest pain
Alarm: bleeding, dysphagia, odynophagia, weight loss
Treatment for GERD
-Lifestyle modifications: elevate head of bed, smoking cessation, avoid laying down after eating, low alcohol intake, weight loss
-Antacids or H2 blockers -tidines (Cimetidine, Ranitidine, Famotidine)
-PPI if > 2 episodes/week
-Nissen fundoplication if refractory
What is gastritis? Name the MC etiology, as well as other etiologies.
Symptoms of this condition
Superficial inflammation of mucosa without injury. Imbalance between aggressive and protective factors.
MC etiology: H. Pylori.
Others: NSAIDs, Aspirin, Stress, Etoh
Symptoms: Most asymptomatic, dyspepsia, n/v
What diagnostics can be done for gastritis?
How do you manage this condition?
Upper endoscopy with biopsy (GOLD)
H. Pylori testing needed as well
Treatment: like PUD (H. Pylori eradication, PPI, H2 blockers)
What are some things in a patient’s history that may lead you to believe they have erosive gastritis?
History of H. Pylori, NSAIDs/Aspirin, acute stress, heavy alcohol use, reflux, radiation, trauma, corrosives
Chronic gastritis, also known as autoimmune metaplastic atrophic gastritis, increases the risk for ______.
This usually occurs in which parts of the stomach?
What is the pathophysiology of this condition?
Gastric adenocarcinoma
Fundus and body
Auto-antibodies against intrinsic factor and parietal cells. Lack of intrinsic factor –> B12 deficiency (pernicious anemia).
With peptic ulcer disease (PUD), which type is usually benign and which type is associated with gastric adenocarcinoma?
What is the pathophysiology of each of the two types?
Duodenal (MC): Usually benign
Gastric: Associated with gastric adenocarcinoma
Patho: Imbalance between (increased aggressive factors - duodenal ulcers) and (decreased protective factors - gastric ulcers)
With peptic ulcer disease (PUD), which type is usually benign and which type is associated with gastric adenocarcinoma?
What is the pathophysiology of each of the two types?
Duodenal (MC): Usually benign
Gastric: Associated with gastric adenocarcinoma
Patho: Imbalance between (increased aggressive factors - duodenal ulcers) and (decreased protective factors - gastric ulcers)
MCC of PUD?
Name symptoms of both types of ulcers.
Because PUD is the MCC of an upper GI bleed, what are symptoms of a bleeding ulcer? How about a perforated ulcer?
H. Pylori
Dyspepsia
-Duodenal ulcer: pain relieved with food, younger patients (30-55), worse before meals
-Gastric ulcer: pain worse with food, older patients (55-70)
Bleeding: hematemesis, hematochezia
Perforated: sudden onset pain, may radiate to shoulder, rebound tenderness, rigidity, guarding, etc.
Upper endoscopy with biopsy is the diagnostic of choice for PUD; however, what else should be done (there are four ways to test for it).
H. Pylori Testing
-Upper endoscopy with biopsy is GOLD standard
-Urea Breath Test
-Stool Antigen (confirms eradication)
-Serologic antibodies (only to confirm)
If the patient with PUD is H. Pylori positive, what two treatment regimens can be done?
Quad Therapy: Bismuth + Tetracycline + Metronidazole + PPI X 14 days
Triple Therapy: Clarithromycin + Amoxicillin + PPI X 10-14 days
–Metro if PCN allergy
If the patient with PUD is H. Pylori positive, what two treatment regimens can be done?
Quad Therapy: Bismuth + Tetracycline + Metronidazole + PPI X 14 days
Triple Therapy: Clarithromycin + Amoxicillin + PPI X 10-14 days
–Metro if PCN allergy
If the patient with PUD is H. Pylori positive, what two treatment regimens can be done?
Quad Therapy: Bismuth + Tetracycline + Metronidazole + PPI X 14 days
Triple Therapy: Clarithromycin + Amoxicillin + PPI X 10-14 days
–Metro if PCN allergy
If the patient with PUD is H. Pylori positive, what two treatment regimens can be done?
Quad Therapy: Bismuth + Tetracycline + Metronidazole + PPI X 14 days
Triple Therapy: Clarithromycin + Amoxicillin + PPI X 10-14 days
–Metro if PCN allergy
If the patient is H. Pylori negative, what treatment should you do?
PPI, H2 blocker, Misoprostol
-Smoking, ETOH, and NSAIDs cessation. Prophylaxis with Misoprostol or PPI in patients with a history of an ulcer
What is the order of treatment (pharm therapy) in which you should give patients if they have PUD?
-OTC antacids –> H2 Blockers –> PPI’s if H. Pylori negative
If the PUD is refractory to pharm therapy, what is the last line treatment?
Bilroth II surgery
Proton Pump Inhibitors (PPI)’s, such as _____, _______, and ________, have a MOA of….
Omeprazole, Lansoprazole, Pantoprazole
Block H/K ATPase of parietal cell, decreasing acid secretion
What are some recommendations for taking PPI’s?
Adverse Effects?
Take 30 minutes before meals
-B12 deficiency, C. Diff, Hip fractures
