order in figuring out malabsorption work up

100 g fat- 72 hrs

if >14 g/d fat in stool:
2. give d-xylose abs

if absorbed–give pancreatic enzymes
if not abs– do EGD and bx

orders to stablilize GI bleed

``` 2 large bore IV's, IVF IV PPI T&S call GI if cirrhotic- add ceftriaxone, octreotide ```

if lower GI bleed, evaluate rate of bleed. how?

stopped --> c-scope brisk --> arteriogram, embolize increasing --> tagged RBC scan

dieulafoy

normal variant artery close to mucosal surface dx with EGD tx: resect

dx and tx of ischemic colitis

dx: c-scope tx: supportive care

AVM associated with

aortic stenosis

dx and ts of gastroparesis

dx: 1) EGD 2) emptying study tx: metoclopramide (stable), erythromycin (for flares) avoid opiates, ACs small meals

plummer vinson sxs

esophageal webs dysphagia Fe def anemia esophageal cancer

tx of esophageal stricture

PPI | dilation

dx of dysphagia

if motility: barium swallow, manometry, EGD + bx if mechanical: barium swallow, EGD + bx

peptic ulcer appearnance in NSAIDS vs h pylor vs malignancy etiologies

NSAIDS: shallow, multiple H pylori: single malignancy: heaped, necrotic

h pylori dx techniques and when to use which one

urea breath- initial dx serology- test & treat (if never been tested and have sxs) EGD + bx- best stool Ag- good to monitor eradication

zollinger- ellison sx

gastrin level - <250: nl - >1600: gastrinoma - in between: secretin stim test (will stimulate gastrin level by >200) somastostain receptor s CT

which hepatitis can be acute

hep A | Hep B

which hepatitis can be chronic

hep B hep C Hep D

which hepatitis have vaccines

hep A and B

RNA or DNA for hepatits

A: RNA B: DNA C: RNA D: DNA

treatment for hep C

PI= direct acting antagonists (borcephexin)

which IBD has crypt abscesses

which IBD has noncaseating granulomas

crohns

extra- intestinal symptoms of UC

PSC | p-ANCA

cullen vs turner sign

cullen: umbilical hematoma turner- flank hematoma (turn on side) signs of pancreatits

whats more specific for pancreatits- amylase vs lipase

lipase

when do you do an ERCP with pancreatitis

only if gallstone etiology

early complications of pancreatitis (1-3 days)

ARDS hypocalcemia pleural effusion ascites

mid complications of pancreatitis (1-3 weeks)

sepsis- check with CT

late compications of pancreatitis (3-7 weeks)

abscess pseudocyst

when to drain and biopsy pancreatic pseudocyst

>6 cm or >6 weeks

what test in suspected cholecystits if US neg

HIDA scan

what test in suspected choledocholithiasis if US neg

MRCP

what sxs in choledocholithiasis

jaundice +/- hepatitis, pancreatits (stuck in bile duct) murphy's

tx choledocholithiasis and cholangitis

1) ERCP npo, ivf, iv abx 2) chole

dx esophagitis

EGD + bx

types of esophagitis

``` Pill-induced Infectious Eosinophilic Caustic (ingestion of substance) GERD ```

when to do EGD + bx in GERD

if alarm sxs or if 6 week PPI trial fails

treatment for barret's esophagus

increase PPI dose

tx for esophagus dysplasia

local ablation (rad, laser, cryo)

stool osmotic gap for secretory vs osmotic diarrhea

= mean Osm - 2(Na+K) if <50: secretory if >100: osmotic
