What non-variceal EGD findings, if any, deter you from using atezo/bev in patients with advanced HCC?
I would discuss the severity and risk of bleeding with the endoscopy team and start beta blockers as indicated before starting anti-angiogenesis therapy.
What is your approach to explaining the role of the microbiome to patients with inflammatory arthritis?
The gut microbiota play a central role in modulating the inflammatory response. This is especially relevant to inflammatory arthritis, where the pathogenesis is quite well understood, especially as it relates to arthritis associated with inflammatory bowel disease. We also know that the diet is the ...
In patients who have failed 5-ASA and have moderate to severe UC, do you utilize 5-ASA as an adjunct, especially rectal therapy?
Good question. There are two separate questions here. The first is regarding oral 5-ASA therapy. In patients who require initiation of advanced therapy for control of their ulcerative colitis after failing 5-ASA, both the AGA and ACG guidelines for moderate to severe UC recommend not continuing 5-AS...
Should all patients diagnosed with B12 deficiency get a baseline EGD?
It is important to determine the cause of B12 deficiency. The majority of cases are due to pernicious anemia (atrophic gastritis and lack of intrinsic factor), I presume this question relates to that group. If there is another cause such as intestinal malabsorption or bacterial overgrowth, this does...
What is your preferred approach in treating recurrent bleeding from GAVE?
If repeated APC has not helped, I ask our advanced endoscopists to perform RFA. If it is a nodular GAVE, then banding is another option.
How do you sequence antiviral therapy and cancer-directed therapy in a newly diagnosed patient with hepatocellular carcinoma and incidentally found hepatitis C?
According to the recent publication by Cabibbo G, et at, J. Hepatol. 2019, 71, 265–273, yes direct-acting antivirals after successful treatment of early hepatocellular carcinoma improves survival in HCV-cirrhotic patients. No such data or evidence for advanced disease though. in that case, antiviral...
Would you consider sotalol to be a suitable non-selective beta blocker for primary prevention of variceal bleeding in a patient who requires sotalol for treatment of arrhythmia in the setting of Fontan-associated liver disease and clinically significant portal hypertension?
The answer to this question will need to be case-by-case, unfortunately.The short answer:The priority in this patient's case for using sotalol is likely the underlying heart disease and its associated arrhythmia, and this cardiac benefit would not be achieved by carvedilol and other NSBBs. Thus, it ...
Which patients with cirrhosis and portal hypertension are ideal candidates to undergo TIPS to reduce perioperative risk in anticipation of an elective surgery?
A pre-operatively placed TIPS may have a role in preventing hepatic decompensation and post-surgical complications in carefully selected patients undergoing elective abdominal surgery. The data to support TIPS pre-operatively is limited, given the varying surgical contexts and the generally poor pro...
Do you obtain liver biopsy to confirm the diagnosis of cirrhosis if cirrhotic liver morphology is noted on imaging?
This question touches upon two interesting trends: 1) There is an increasing trend in Radiology to report "cirrhotic liver morphology" in the "Impressions" section. When you then review the Body of the report, often these cases are noted to only have a heterogeneous appearing liver with surface nodu...
What is your approach to the management of post-TIPS hepatic encephalopathy?
In general, this will depend on if HE is provoked or unprovoked. Provoking factors such as infection, dehydration, medications (sedatives) or GI bleeding are reversible and often do not require aggressive HE treatment when the underlying trigger is removed. It may be reasonable to consider lactulose...
