Progressive w/Heartburn- scleroderma
Intermittent w/ chest pain- DES
Dxtix for DES
Barium swallow showing corkscrew appearance
Tx: trial of PPI; CCB

Intermittent: eosinophilic esophagitis
Indications for EGD
Anemia Melena Weight loss Dysphagia or odynophagia Poor response to PPI for 4-8 weeks GERD sx > 5 yrs
T/F tx of barrett’s esophagus w/ PPI or fundoplication reverses the epithelial changes
F
EGD for Barretts
If no dysplasia, rpt in 3 yrs
If w/ low grade dysplasia, rpt in 6 mos. if still dysplasia, rpt in 1 yr; if already metaplasia, repeat in 3yrs
If high grade dysplasia, endoscopic radiation ablation and repeat egd in 1 yr
Dxtic for esophageal rupture
Gastrograffin study
Difference bet type A and B chronic gastritis
Type A: (AAA) more common in fundus Atrophic gastritis Anemia - Pernicious adenoCA-- 3x risk (no need for surveillance) Inc gastrin
Type B:
H pylori associated
More common in antrum
T/F diet, personality, occupation play a role in PUD
F
Tx of maltoma?
H pylori tx
After tx repeat biopsy before annpuncing cure bec t (8,11) has poor response to tx
Best test for h pylori diagnosis when px is on PPI
Ab testing
Tx regimen for PUD
PAC: PPI + amox + clarithro
MOC: Metro + Omep + clarithro
Tx failure w/ PUD regimen
Tetracycline + bismuth + metro + PPI
Zollinger ellison syndrome
Gastrinomas; associated w: men 1
Presents w/ diarrhea/ steatorrhea

Fasting gastrin level
If not dxtic, IV secretin w/c inc gastrin to > 1000
CT or somatostatin scintigraphy to localize
Tx for ZES
PPI, resection

Postgastrectomy there is postprandial bloating/pain relieved with bilious vomiting
Blind loop syndrome
Postgastrectomy – bacterial overgrowth (low B12, normal folate) — steatorrhea

Tx: cholecystectomy
Gb sludge & pancreatitis?
What to do
Ercp w/ biliary sampling — cholecystectomy
Why do yearly US for ulcerative colitis?
To look for GB polyps
If + and > 1cm, cholecystectomy bec of high risk of CA
Marker for autoimmune pancreatitis?
IgG4
Tx: steroids
Finding in pancreatic divisum
Dilated dorsal duct
In pancreatitis, marker for biliary etiology?
ALT 2x elevated; alkphos rises later
Soap bubble sign in pancreatitis
Abscess; abx and drainage
For persistent fever > 72 hrs, open drainage
Persistently elevated amylase in pancreatitis?
Consider pseudocyst

Solid component Enhancing thickened wall Nodule RBCs or inflammatory cells Size 3cms or more Dilated pancreatic duct > 1cm \+ cea \+ pathology
What to do if pancreatic cyst has worrisome features
Confirm with EUS
3cm panc cyst w/ no worrisome features on eus
MRI or EUS every 3-6mos
2cm panc cyst w/ no worrisome features on eus
MRI or EUS every 2-3 yrs
Dx for steatorrhea
Stool fat > 40g
Tx for chronic pancreatitis
Pancrealipase x 6 wks; if no response, pregabalin
Path in IBD
