AAA, mestenteric ischemia, SBO, ectopic pregnancy, ovarian torsion, appendicitis, MI, cholangitis
What is the classic triad seen in 50% of AAA patients?
hypotension/syncope, pulsatile mass, dull abd pain
What is the imaging to assess AAA?
abd bedside US or abd CT with contrast
When to use abd US for appendicitis eval?
young non-obese, pregnant
When to use abd CT for appendicitis?
everyone else! use oral contrast if broad ddx, and IV if thin
What are the cutoffs for making C diff severe disease?
age > 65, Cr > 1.5x baseline, wbc > 15
What is a surgical emergency associated with c Diff?
colonic ileus / toxic megacolon
What are RF for c diff coliits?
recent abx, recurrence, PPI, chemo, IBD
What is the branch point for diverticulitis in terms of mgmt?
uncomplicated (microperforation) vs complicated (macroperforation) - abscess, peritonitis, fistula formation, obstruction (from inflammation)
What is the outpt mgmt for divertculitis if pt meets criteria?
cipro and flagyl for 10-14 days
What are the criteria needed for diagnosis of pancreatitis?
Epigastric characteristic pain; lipase > 3x normal; abd imaging
What are things to check for pancreatitis?
TG, RUQUS, alcohol levels (if unclear story)
What is the imaging needed for ovarian torsion?
TVUS
What are the RF for mesenteric ischemia?
PVD, Afib, CAD, valvular disease, AAA
What is definitive imaging for Mestenteric ischemia?
CT angiography
What are the four main systems for abd pain?
think GI; think GU/gyne; think cardiac. Also think vascular.
What are the indications for an ERCP when suspecting CBD stone?
high risk of CBD
If imaging shows CBD stone OR
cholangitis OR
bilirubin > 4mg/dl AND
Dilated CBD (>6mm/8mm)
What about approach to intermediate risk of CBD stone?
EUS or MRCP or lap chole with intraop cholangiogram
Charcot’s triad vs Reynold’s pentad
RUQ pain, fever, jaundice
+/0 AMS and hypotension
not seen in more than half of cholangitis patients
What are other guidelines that can be used for Acute cholangitis?
Tokyo guidelines!
Immediate treatment of acute cholangitis?
IV fluids and IV abx
cipro +/- flagyl (GNR + enteroccocus)
2 out of 3 criteria for acute pancreatitis diagnosis?
1) lab - lipase 3x greater than normal
2) epigastric pain
3) CT imaging
single best imaging is abd ultrasound!
When is abd CT helpful in pancreatitis?
diagnosis unclear, not improving after 48-72 hr
What are labs and imaging you can get in pancreatitis?
labs - lipase, liver labs, TG (looking for dx)
imaging: CT esp if over 40 to look for mass if not sure about diagnosis
What are predictors of mortality in acute panreatitis?
BUN if greater than 20 or rising more than 2 in 24 hours
what is harmless acute pancreatitis score
normal hct; normal Cr; no abd guarding and/or rebound - 99% PPV of it’ll go ok!
What are fluid treatment requirements in pancreatitis?
Bolus 10cc/kg then 1.5 cc/kg/hr
1.5 cc / kg/hr
WATERFALL 2022 NEJM study
Nutrition for pancreatitis ?
start within 24-48 hours
do not NEED to start with clear liquids (low fat, normal fat, soft or normal diets are fine)
NGT or NJT > TPN
when should CCY timing happen in mild gallstone pancreatitis?
BEFORE DISCHARGE
