GI 2 Flashcards
Esophageal cancer
Proximal 2/3: squamous cell carcinoma. Risk factors: alcohol, tobacco, achalasia, esophageal webs
Distal 1/3: adenocarcinoma. Risk factors: smoking but not alcohol, Barrets/GERD
Esophageal cancer metastasizes to
Lung and liver
And mets from melanoma and breast cancer
Hematemesis DDX
Frank blood: esophageal cancer, rupture (eating disorder? Huge food bolus?), varices (do you have liver dz?)
Coffee ground: gastric ulcer that hemorrhages, erosive gastritis (NSAIDs, alcohol, stress virus?)
Symptom that indicates dysphagia due to esophageal cancer
Progressive! (No solids–> no liquids–> drooling)
Weight loss
How to dx esophageal cancer
Endoscopy w biopsy
Gastritis versus PUD
Erosive gastritis: caused by NSAIDs, alcohol, stress, radiation, viral. Sxs: dyspepsia, N/V, hematemesis, melena
Non erosive: caused by H pylori. Asx.
PUD: caused by H pylori, NSAIDs, cigarettes, family hx, Zollinger Ellison syndrome. Sxs: epigastric pain, relieved by food/antacids, burning/gnawing
What predisposes patient for gastric cancer?
H pylori, autoimmune metaplastic atrophic gastritis
Gastric ulcer versus duodenal ulcer Sxs
Gastric- no pattern
Duodenal- consistent pattern, better w food, worse 2-3 hrs after meal (post prandial), pain awakens pt at night
Complications of PUD…
Hemorrhage Penetration Free perforation Gastric outlet obstruction Recurrence Gastric cancer
Acute pancreatitis
Cause: chronic, heavy alcohol intake, biliary tract dz
Sxs: steady, boring, upper abdominal pain, radiating to back, N/V
Labs: 3x elevated amylase and lipase, elevated WBCs
X-rays: pancreatic duct calcification, US may show gallstone
What is the pancreatic position?
Bent over, sitting froward, fetal position
Classic triad of chronic pancreatitis
Pancreatic calculi, steatorrhea, DM
Labs for acute vs chronic pancreatitis vs pancreatic cancer
Acute: very high amylase and lipase
Chronic: normal to low
Cancer: normal to low amylase and lipase, high alk phos and bilirubin
Chronic pancreatitis Sxs
Post-prandial pain is dominant sx. Episodic, hours-days
Dx based on Sxs and history
Pancreatic cancer
Serious dx if found late (90%).
Sxs: severe abdominal pain, wt loss, jaundice and pruritis (head), splenomegaly, gastric/esophageal varices (body and tail); diabetes in 25-30%
