    Study Notes

    Foreign Bodies in the Stomach and Intestine

    • 95% of ingested objects pass through the gastrointestinal tract without difficulty
    • Objects longer than 6 cm or wider than 20 mm in diameter often fail to pass through the pylorus
    • Open safety pins require urgent endoscopic removal
    • Small magnets should be removed if in the esophagus
    • Multiple magnets can cause bowel perforation
    • Lead-based foreign bodies can cause lead poisoning
    • Water-absorbing polymer balls can expand in the small intestine and cause obstruction
    • Objects inserted into the rectum typically need to be retrieved
    • Batteries larger than 15 mm are less likely to pass spontaneously

    Bezoars

    • A bezoar is an accumulation of matter in the stomach or intestine
    • They are primarily composed of food or fiber

    Antisecretory Therapy With Pediatric Dosages

    • H2 Receptor Antagonists
      • Ranitidine: 4-10 mg/kg/day divided 2 or 3 times a day
      • Famotidine: 1-2 mg/kg/day divided twice a day
      • Nizatidine: 5-10 mg/kg/day divided twice a day
    • Proton Pump Inhibitors
      • Omeprazole: 1.0-3.3 mg/kg/day
      • Lansoprazole: 0.8-4 mg/kg/day
      • Rabeprazole: 5-10 mg/day
      • Pantoprazole: 0.3-1.2 mg/kg/day (limited data)
      • Esomeprazole: 2.5-10 mg (depending on weight)
      • Dexlansoprazole: 30-60 mg
      • Omeprazole sodium bicarbonate: Not approved for use < 18 years
    • Cytoprotective Agents
      • Sucralfate: 40-80 mg/kg/day

    IBD (Inflammatory Bowel Disease)

    • Ulcerative colitis and Crohn disease have a higher prevalence among relatives of patients with the same disorder
    • The concordance rate for twins is higher for Crohn disease (36%) than for ulcerative colitis (16%)
    • The first IBD gene, NOD2, was identified in 2001
    • Since 2006, there has been an exponential growth in the set of validated genetic risk factors for IBD
