GI Flashcards
First step in obscure GI bleed
Repeat EGD/c-scope, NOT push enteroscopy
Treatment of opioid-induced constipation
Oral naloxegol (opioid receptor antagonist) OR oral nadlemedine OR subcutaneous methylnaltrexone
When to initiate therapy for chronic HBV
- In the immune-active phase, HBeAg-postive and reactivation, HBeAg-negative phase
AND Elevated aminotransferase levels and hepatic fibrosis
Management of patient with chronic hep B in immune tolerant phase (active viral load)
Serial monitoring of aminotransferase levels.
Preoperative aspirin management for colonoscopies
- Continue for patients with established cardiovascular disease
- Discontinue after polypectomy in patients without established cardiovascular disease
NAFLD on liver ultrasound
Hyperechoic
Autoimmune hepatitis diagnosis
HIGH titer antibody (20-30% of patients with NALFD can have low titer antibody levels) + requires liver biopsy
What is pseudoachalasia?
TUmor at GEJ infiltrating the myenteric plexus causing esophageal motor abnormalities (symptoms, barium-imaging and manometry and endoscopy are similar to achalasia)
How to differentiate pseudoachalasia from achalasia
Achalasia = insidious onset, long duration of symptoms (years) before patients seek attention Pseudoachalasia = short duration of symptoms, rapid weight loss
Treatment for diarrhea-predominant IBS
low-FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) diet
How to diagnose zenker diverticulum
Barium esophagram (you can see it with endoscopy but too high risk for perforation if endoscope enters diverticulum)
Presentation of zenker diverticulum
- Regurgitation of undigested food + halitosis + esophageal dysphagia
Diagnosis of hepatopulmonary syndrome
TTE w/ agitated saline demonstrating that shunting of blood is not intracardiac
Pathophys of hepatopulmonary syndrome
Dilation of pulmonary vasculature in setting of advanced liver disease
Classic features of hepatopulmonary syndrome
Platypnea (worsening shortness of breath in upright position)
Orthodeoxia (worsening o2 sat in upright position)
Presentation of acalculous cholecystitis
biliary colic + sepsis-like + jaundice + critically ill patient + soft palpable mass
Treatment for acalculous cholecystitis
IF unstable –> cholecystostomy tube placement
IF stable –> cholecystectomy
IV abx, bcx
Management of patient requiring NSAID with history of PUD
celecoxib + PPI
Follow-up colonoscopy interval if hyper plastic polyps
10 years (unless greater than 10 mm), they are non neoplastic
Follow-up colonoscopy interval if sessile serrated polyps
5 years
Follow-up colonoscopy interval if 3 or more adenomas
3 years
Follow-up colonoscopy interval if polyp with villous or high-grade dysplasia
3 years
Next step for ascending cholangitis
ERCP
Treatment of toxic megacolon
1) Urgent colectomy
2) IV high dose steroids,
3) broad spectrum abx
