How would you approach endoscopic diagnosis and treatment of an area of visible nodularity concerning for cancer within long segment Barrett’s esophagus?
I would begin by careful inspection of the Barrett's (BE) mucosa under HD-white light and narrow band imaging after washing off the surface mucus. I would evaluate the entire BE segment for nodules, ulcers, irregularities in pit-pattern and focal changes in vascular pattern, raising suspicion for in...
Would you pursue a colonoscopy for a patient in their 20s with constipation and rectal bleeding if they had a first-degree relative who died young from a "carcinoid tumor"?
Carcinoid tumor is relatively uncommon in someone who is relatively healthy and young. I would make sure to consider all the more common diagnoses and workup before considering carcinoid tumor. Moreover, carcinoid tumor is associated with diarrhea rather than constipation. Neuroendocrine tumor of th...
How do you approach using fecal microbiota therapy for recurrent Clostridioides difficile infection in immunocompromised patients?
We generally do not do the single donor FMT via colonoscopy, that was popular 5-10 years ago. We do offer both the oral and enema-based products, with a slight preference for the oral-based product due to ease of use.
How long do you recommend waiting after variceal bleeding and banding before a transesophageal echocardiogram can be performed safely?
In the exact wording of this question, the scenario that is being presented is that the patient has had a variceal hemorrhage (VH) recently and urgent banding has already been performed to stop the VH (so that the concern would be of the TEE probe knocking off a band that is actively treating an eso...
What is your preferred screening tool for colon cancer in an average-risk patient?
For their first time screening, I universally recommend a colonoscopy (in the absence of contraindications or social barriers) to evaluate for polyps, followed in 5-10 years by a yearly FIT or Cologuard every three years (unless the patient has a strong preference for a repeat colonoscopy). Repeat c...
How do you determine whether to limit volume removal during therapeutic paracentesis in a patient without acute or chronic kidney disease?
Large volume paracentesis (LVP) can lead to complications such as post paracentesis circulatory dysfunction. In patients who have ongoing acute renal failure, patients with borderline low blood pressure, or in patients who have a history of hyponatremia, LVP should be limited to 5L.
How do you approach a patient on anti-TNF with positive Quantiferon (previously negative) with negative chest x-ray and no symptoms?
Prior to routine screening for latent TB for patients receiving or about to receive TNF inhibitor therapy, there were reports of miliary TB developing after initiation of TNF inhibitors. Therefore, one cannot say that a negative chest x-ray and no symptoms means the patient is not at risk for develo...
Is there a role for use of JAK inhibitors instead of corticosteroids to induce clinical remission in those with severe ulcerative colitis?
Tofacitinib and upadacitinib are specifically approved for the treatment of moderately to severely active ulcerative colitis (UC), and both had steroid-sparing endpoints in their clinical trial programs. However, so do many of our newer therapies for UC. Both agents have demonstrated efficacy within...
How do you approach a patient with IgG4-related disease who has failed rituximab and mycophenolate and continues to rely on high-dose steroids?
Most cases of IgG4-RD respond to rituximab similar to the steroid treatment. When there is a lack of response to moderate dose steroid or rituximab, either the diagnosis is not IgG4-RD or the manifestation is not due to active IgG4-RD. In many cases, if treatment is delayed, fibrosis takes over the ...
How do you approach the treatment of Crohn's colitis in the setting of immunosuppression for liver transplant?
Good question, as additional immune suppression can increase the risk of infection. The anti-rejection drug mycophenolate can cause diarrhea, which could mimic a Crohn’s flare. I individualize Crohn’s therapy in a liver transplant patient. What type of Crohn’s do they have? What meds were they on pr...
