DSA 3 - Hepatobiliary Patient Gallbladder Biliary (McGowan) Flashcards

1
Q

What is the clinical test used to test for acute cholecystitis? How does it work?

A

Murphy’s Sign

Patient exhales, physician places hand below costal margin on the right side at mid-clavicular line, patient inspires. It’s positive if the patient stops breathing in and winces with a “catch” in their breath due to pain.

23
Q

What is the most direct and accurate means of determining the cause, location, and extent of obstruction for Choledocholithiasis?

A
    • ERCP
    • Percutaneous transhepatic cholangiography

***EUS can also be helpful!

24
Q

What is it vital to check before an ERCP?

A

INR (always check this before invasive procedures)

25
Q

What are the treatment options for Choledocholithiasis and Ascending Cholangitis?

A

– ERCP with sphincterotomy and stone extraction/stent placement (procedure of choice)

– Cholecystectomy

– Antibiotics, pain meds, IVF

26
Q

What is the main complication that Choledocholithiasis can lead to?

A

Ascending Cholangitis

27
Q

What disorder should we suspect when the patient presents with fever, gram-negative shock, jaundice, and leukocytosis? Also can have biliary pain and N/V.

A

Ascending Cholangitis

28
Q

Acute Cholangitis has a characteristic of symptoms called Charcot Triad, which includes…

A
    • RUQ pain
    • Fever (and chills)

Q

If Acute Cholangitis develops into Acute Suppurative Cholangitis, it presents with something called Reynold Pentad. What does this include?

A

+

– Altered mental status (confusion) and hypotension

30
Q

What are the lab results for Ascending Cholangitis?

A

– Leukocytosis

– Positive blood cultures for E. coli, Klebsiella, Enterococcus

– Increase in AST and ALT (greater than 1000)

– ALP and GGT rise slowly

Q

What is the best diagnostic imaging technique for Acute Cholangitis?

A

***Remember to check INR beforehand!

32

A

Biliary Dyskinesia

40
Q

What is the best imaging to perform for Biliary Dyskinesia diagnosis?

A

– There will be a NORMAL ultrasound for this, so other diagnostics are preferred.
