How do you diagnose and manage suspected opioid-induced esophageal dysfunction?
Patients with opioid-induced esophageal dysfunction have symptoms of most often, chest pain or dysphagia, with manometric findings of EGJ outflow obstruction, type 3 achalasia, or esophageal spasm/hypercontractile/jackhammer esophagus. When manometry suggests EGJOO or type 3 achalasia, in our practi...
Would you consider a combination of anti-TNF therapy and azathioprine upfront in a young male with Crohn’s disease considering its risk of lymphoma in the era of several advanced therapies?
Definitely, TNF + IMM hasn’t been beaten in efficacy. If the patient is in clinical and endoscopic remission at 6-12 months with good IFX levels, then they can stop the IMM.
Which GI cancer patients do you use oral contrast in staging CT scans?
We do not use oral contrast for most of our patients and only offer oral contrast CT scans for patients we are concerned about perforation.
Under what circumstances do you give chemotherapy for a nondiagnostic pancreas biopsy that is suspicious for adenocarcinoma?
Assuming it is a localized pancreatic abnormality and no "metastases," I would not give chemotherapy as such. If anything, I would consider surgical removal, which will also give the exact diagnosis. To start, chemotherapy is not curative (maybe if it were a lymphoma!). There may be some way of doin...
In a patient with unresectable HCC who developed immune-related colitis with the first dose of tremelimumab/durvalumab, would you consider continuing durvalumab alone after resolution of the colitis with steroid treatment?
I haven’t seen too many TREMI/DURVA colitis cases, but basing experience off of BOT/BAL, which is notorious for the CTLA-4 inhibitor-related BOT-colitis, as well as some patients who have had IPI/NIVO colitis, or any grade ≥3 event in the combination setting, it’d be reasonable to continue the PD1/P...
How do you decide when to initiate or restart diuretics in a cirrhotic patient with ascites if they are receiving a therapeutic paracentesis?
This question has two parts, one with a straightforward answer, the other with a much more nuanced answer, if I understand it correctly. Any patient receiving a therapeutic paracentesis should start/restart diuretics afterwards. Per the 2021 AASLD guidelines, one of the statements reads “LVP is the ...
What surveillance is recommended for a C1M3 segment of columnar-lined esophageal mucosa with repeated biopsies demonstrating columnar metaplasia but no goblet cells/intestinal metaplasia across multiple endoscopies?
Based on current U.S. guidelines, routine endoscopic surveillance is not recommended for columnar-lined esophagus without intestinal metaplasia (goblet cells). The American Gastroenterological Association (AGA) does not consider this Barrett's esophagus and does not recommend using that term or perf...
What factors can lead to falsely elevated fibrosis readings on FibroScan (e.g., consuming sugar before the scan)?
I recommend 3 hours of fasting before performing a FibroScan. Liver stiffness may not be equivalent to fibrosis stages in the following conditions: liver congestion (right-sided heart failure, Fontan-associated liver disease), active liver inflammation (alcohol, active viral or autoimmune hepatitis)...
For high-risk ulcer bleeding requiring early anticoagulant resumption, what endoscopic/clinical threshold prompts you to add adjunctive prophylactic hemostatic powder specifically to support earlier restart?
If there is a high-risk ulcer, I would treat it as indicated. If, at the end of treatment (whether with injection + thermal therapy/ clips, etc), I am not confident that I rendered effective treatment, then I would apply hemostatic powder.
How would you approach the evaluation of a patient with decompensated cirrhosis, suspect to be due to alcohol, who is not a liver transplant candidate with iron studies showing elevated saturation and ferritin over 1000?
The finding of elevated iron saturation (I suspect means above 55%) and high ferritin raises the diagnosis of true iron overload. Certainly, a Ferritin level above 1000, when the patient is not actively drinking, is consistent with cirrhosis. So, I would start phlebotomies if the Hgb >11-12 g/dL all...
