52
Q

A

Can be diagnosed based on clinical symptoms alone!

  • Upper endoscopy may need to be done to evaluate alarming features of gerd
    • new onset of dyspespia in those older than 60
    • GI bleeding
    • Pain
    • Cancer Fhx
    • Persistent vomit
    • Dysphagia
    • Odynophagia
53
Q

GERD treatment?

A
  • Lifestyle mods:
    • Loose weight, eliminate triggers, elevate head of bed, no smoking or alcohol
  • Antacids
  • Surface agents
  • H2 blockers decrease secretion of acid by blocking Histamine 2 receptor-Zantac
  • Proton pump inhibitors: most potent inhibitors of gastric secretion by irreversibly binding and inhibiting H/K atpase-Omperazole
54
Q

PUD?

A
  • 1:1000 person yrs in general pop
  • Peptic ulcers are defects in gastric or duodenal mucosa extending through muscularis mucosa
    • risks: H. Pylori or NSAIDs use, smoking and alcohol
  • Sx: most are asympotmatic, Upper ab pain, primarily epigastric but can be in RUPQ and LUQ may present as GI bleed or perforation
  • Most common causes of UGI bleeding
55
Q

Difference between gastric and duodenal ulcers?

A
  • Gastric ulcers NSAIDs are risk factors and H Pylori typically in the lesser curvature of stomach. sharp burning epigastric pain worsening 30 min to hour half after eating
  • Duodenal ulcer H. Pylori infection, proximal duodenum multiple ulcers or ulcers distal to 2nd portion of duodenum. Sx include gnawing epigastric pain, worsening 3-5 hrs after eating, may be relieved by food/eating
56
Q

What is H. Pylori associated with? KNOW

A
  • PUD
  • Chronic Gastritis
  • Gastric adenocarcinoma
  • Gastric mucosa associated lymphoid tissue lymphoma and duodenal ulcers
57
Q

How does H pylori penetrate gastric mucus layer?

A
  • Urease hydrolyzes gastric luminal area to form ammonia that neutralizes gastric acid and protects the bacterium.
  • Affects:
    • inicreased gastric acid secretion
    • gastric metaplasia
    • immune response
    • mucosal defense mechanisms
58
Q

Melena is 90% of the time secondary to __.

Q

Achalasia (Zebra :) )

A
  • Uncommon!
  • Results from progressive degeneration of ganglion cells in the myenteric plexus in esophageal wall leading to failure of LES to relax with a loss of peristalsis in distal esophagus

  • Bird beak barium x ray
  • Confirm diagnosis with esophageal manometry, swallow probe measuring GI tract pressure. NOT often done
74
Q

Chagas disease? (Zebra!)

A
  • Secondary achalasia cause, indistinguishable from primary idiopathic achalasia, can also cause cardiomyopathy and megacolon, and swelling at sign of bite
    • romanha sign: swollen at eye
    • Chagoma swelling else where
  • Usually considered in patients from endemic region
  • Caused by parasite Trypanosoma cruzi
75
Q

Zollinger ellison syndrome? (Zebra)

A
  • VERY uncommon
  • Caused by secretion of gastrin by duodenal or pancreatic neuroendocrine tumors
  • Gastric acid hypersecretion resultisn in severe acid related PUD and diarrhea
  • consider with intraqctable ulcer/recurrent/severe ulcer diseasses
  • Ulcers in atypical locations, ulcer with diahhrea steatorrhea weight noss N/V
  • Positive secretin stimulation test and elevated fasting gastrin levels
76
Q

Viscerosomatics? (Know)

A
  • PSNS:
    • upper portion esophagus through transverse colon OA, AA (vagus)

    • Stomach T5-9
    • Liver/ GB T6-9
