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.
In patients with longstanding UC or Crohn's colitis, would you extend the interval of surveillance colonoscopy to longer than 3 years if they have had little inflammatory disease over the years and no other factors to increase their risk (ie, history of polyps, history of dysplasia, or family history)?
AGA Practice Update says you can go to 5-year interval. Murthy et al., PMID 34416977
How do you remove and code for the following polyps?
I would inject and remove with a hot snare. It also depends on the location of the polyp. If the polyp is in the cecum, I would use a cold snare. I would code this as EMR. I would inject and remove this one also in one piece if possible. I would code this as EMR.
How does the presence of gallbladder sludge vs stones on POCUS impact your suspicion for gallbladder disease as a cause of abdominal pain?
With all point-of-care ultrasound, so much depends on your pre-test probability before you acquire the image. If you are simply trying to identify biliary colic in a patient with a good history of the disease, then the presence of either sludge or stones is quite an effective test with bedside provi...
When do you send for genetic testing (e.g., SPINK1, PRSS1, CFTR) in a patient with recurrent or chronic pancreatitis without an obvious etiology and how does it impact your management?
I offer and discuss getting genetic testing in patients with idiopathic recurrent acute pancreatitis or chronic pancreatitis, more frequently in younger patients. Impact of testing can help identify undiagnosed CFTR patients, for whom further CF evaluation and management including options to try new...
Is there a role for use of GLP1 R agonist or dual agonist therapy for management of post bariatric hypoglycemia and dumping syndrome?
There is little systematically collected information in this area on which to base judgments. A case series of 5 post-bariatric surgical patients treated empirically with liraglutide described reduction of hypoglycemic events based on patient history. In an experimental study comparing several treat...
Do you prescribe respiratory muscle training (RMT) devices to patients with dysphagia?
We encounter dysphagia frequently in our patients with Parkinson's disease and other movement disorders. If there are any concerns about swallowing or aspiration, my first step is to refer to Speech Therapy for evaluation, and I defer to their expertise for specific treatments from there. That said,...
What is your approach to duration of fidaxomicin in a patient receiving treatment for first C difficile infection while also receiving concurrent antibiotics for an infection?
Yes, I would extend the duration of Fidaxomicin for at least 7 days past the completion of antibiotics. Additionally, I would consider resuming Fidaxomicin if a patient needs additional antibiotics within 2 weeks of having completed C diff treatment.
Do you recommend food elimination diets for GI eosinophilic disorder not affecting the esophagus?
Yes, food elimination diets would be recommended for eosinophilic gastritis and duodenitis, as per clinical studies and experience (Gonsalves et al., PMID 37462600).
What diet do you recommend for patients with inflammatory bowel disease?
This is a good question and very commonly comes up. The first step is really understanding what the expectations and goals are. If the goal is to achieve remission in people with inflammation who are symptomatic and want to use diet as monotherapy or in conjunction with meds, I discuss various thera...
