How would you manage long-segment Barrett's esophagus with both LGD and HGD that has failed to respond to RFA, cryoablation, or even Nissen fundoplication for large hiatal hernia?
ESD/multifocal EMR followed by may be a great option to assess T-stage/rule out occult esophageal cancer. However, the challenge with a large hiatal hernia is ongoing severe GERD and persistent esophagitis. This is a known risk factor for lack of response to endoscopic ablative and resection therapi...
When giving albumin challenge, for acute kidney injury with suspected hepatorenal syndrome, do you administer a single dose daily or split the dose of albumin?
The main concern about albumin infusions is the potential risk for pulmonary edema (China et al., PMID 33657293). Therefore, I prefer to have albumin administered in divided doses of 25 grams at a time with a max daily dose of up to 100 grams, and I tend to stop IV albumin if the serum albumin level...
Do you feel there is a role for triple-phase budesonide in the management of patients with celiac disease who refuse to follow a gluten free diet?
I do not believe it does. Budesonide is useful for acute gluten exposures and type 1 RCD but will not correct the inflammatory cascade associated with chronic gluten exposure and has significant side effects with long term use.
Is there a role for checking calprotectin, or other markers of inflammation, in decision making or monitoring in patients undergoing abdominopelvic radiotherapy with history of IBD?
The fecal calprotectin is neither sensitive nor specific enough to determine the protocol for radiotherapy. In fact, the very disease requiring the radiation may contribute to the results! If you need to know the condition of the rectosigmoid, a flexible sigmoidoscopy should be your best bet.
Would you ever consider switching a patient with an LVAD from warfarin to Eliquis, such as in the setting of recurrent GI bleeds?
In general, warfarin remains the agent of choice in VAD patients. However, in patients with INR non-adherence or recurrent GI bleeds, it is an option. In this situation, ensure that GI bleeding is stopped and start 2-3 days after warfarin is stopped. Monitoring with anti-factor Xa monitoring can be ...
Should an individual who received the purified protein Hepatitis B vaccine in 1985 receive a booster or have antibody titers checked?
I recommend you ask yourself two questions. How likely has this individual lost humoral immunity? Did they receive B cell deplaning chemotherapy or have CLL, etc? How likely is the individual to be re-exposed? If the answer to both is low, re-vaccination probably provides no benefit.
What is your experience with transesophageal lung mass biopsies?
Thoracic lesions requiring FNA in the mediastinum are often best approached with EUS–FNA, as the sedation and airway management are less complex than the EBUS, and the needle does not need to break through cartilage rings to access the lesion. On the other hand, a lung mass would require the needle ...
In a patient with Zieve's Syndrome and alcohol related cirrhosis which antibiotic regimen is safe to treat H. pylori?
I am not concerned about a cirrhotic patient receiving a fluoroquinolone, macrolide, metronidazole, or doxycycline. The drug insert labels do not raise any particular concerns for these drugs’ use, even in Child Pugh class C cirrhosis. Yes, there is a theoretical potential for overdosing patients on...
At what BMI or waist-circumference threshold do you opt to move from Fibroscan to other NILDA for fibrosis assessment?
The XL-validation study found a liver stiffness measurement (LSM) failure of 1% for the XL and 16% for the M probe, in patients with a BMI of 28 or above. In people with a BMI of 40 or above, the XL-probe failure was 5%, and the best predictor of failure was a skin-to-capsule distance (SCD) ≥25 mm (...
If you do not have easy access to shear wave elastography (aka Fibroscan), what do you recommend for non-invasive tests to determine if a MASLD patient has clinically significant portal hypertension and risk-stratify them?
Great question. I do magnetic resonance elastography (MRE), and if not possible, shear wave elastography (SWE). If I have access to only blood-based non-invasive liver disease assessment (NILDA), will then order enhanced liver fibrosis (ELF). However, for clinically significant portal hypertension (...
