Approach to upper GI symptoms 2 Flashcards
classic cause of esoph. motor dysphagia?
achalasia
achalasia: pathophysl?
hypertrophy of LES muscle. degeneration of neuronal bodies and ganglion cells in myenteric plexus, esp. VIP/NO nerves –> LES doesn’t open, peristalsis not coordinated
symptoms of achalasia
slowly progressive dysphagia for liquids + solids. regurgitation of undigested food esp. at night/when bending over. chest pain. weight loss.
causes of mechanical dysphagia
benign strictures (Webs, rings). schatzke’s ring (ring of mucosal or muscular tissue = narrows LES). esophageal cancer. eosinophilic esophagitis
odynophagia: meaning? causes?
painful swallowing. pharyngeal infections/inflammation. pill esophagitis. infectious esophagitis: candida, CMV, herpes. caustic injury. radiation esophagitis.
odynophagia: how to figure out cause
usually requires endoscopy
common causes of dyspepsia (epigastric pain)
gastric/duodenal ulcer disease. non ulcer dyspepsia. pancreatitis. gall stone disease. causes above diaphragm like MI
how to test for H. pylori
serology (blood sample). mucosal gastric biospy during endoscopy. C13 breath testing.
2 main causes of peptic ulcers
H. pylori + NSAIDs
pathogenesis of NSAID induced ulcers (2)
prostaglandin mediated: inhibit PG which normally stimulate cell turnover/bicarb. direct effect: microvascular injury b/c of increased neutrophil adherence + formation of white clots that result in ischemia
non ulcer dyspepsia: def
symptoms of epigastric pain or discomfort from upper GI tract but not caused by ulcer disease –> nausea, feeling of abnormal/slow digestion, feeling of early satiety
causes of NUD
dietary, lifestyle, stress. med related: antibiotics, aspirin, hormones, narcotics. H pylori infection. motor disorder?
management for dyspepsia
test + treat for HP. investigate with endoscopy if alarm symptoms. treat ulcers: for HP, or with H2 blockers/PPIs
choosing wisely (3)
reassess PPI use at least once a year. avoid UGI series to investigate dyspepsia. avoid endoscopy <55yo unless alarm symptoms
