    Episode 43: The one where I discuss all things Fractyl with Dr. Harith Rajagopalan

    Resetting the Metabolic Setpoint: Duodenal Mucosal Resurfacing (DMR) and the Future of Obesity Care with Dr. Harith Rajagopalan Is the duodenum the "early warning beacon" for metabolic disease? In this episode, we sit down with Dr. Harith Rajagopalan, MD, PhD, Co-Founder and CEO of Fractyl Health, to discuss the revolutionary shift from treating downstream symptoms of diabetes and obesity to addressing the upstream root cause in the gut. We dive deep into the science and technique of Duodenal Mucosal Resurfacing (DMR)—an automated, 45-minute endoscopic outpatient procedure designed to reset the metabolic setpoint. Dr. Rajagopalan explains how high-fat, high-sugar diets pathologically alter the duodenal mucosa and how "resurfacing" this tissue can provide a durable off-ramp for patients on GLP-1 therapies. Key highlights include: The "Reset" Mechanism: How the duodenum acts as the body's nutrient-sensing center and why it becomes dysfunctional. Technical Deep Dive: A look at the automated circumferential saline injection and thermal ablation process (and the future of through-the-scope devices). The "Remain" Trial Data: Breakthrough insights into post-GLP-1 weight maintenance and craving reduction. The Rejuva Platform: A look at the first-in-class EUS-guided gene therapy targeting the pancreas. Whether you are a fellow learning the ropes or an attending looking for the next frontier in interventional GI, this episode explores a future where endoscopists own the management of metabolic disease.

    Episode 40: The one where I explore building a path to Advanced Endoscopy with Dan Marino, MD

    In this episode of The Interventional Endoscopist, host Mankanwal Sachdev sits down with Dr. Dan Marino, a GI fellow at NYU and future advanced endoscopy fellow, to unpack the real-world pathway to a fourth-year advanced endoscopy fellowship. Dan shares his journey from New Jersey soccer goalie to medical student, resident, fellow and ultimately interventional endoscopy fellow. He discussed how early mentorship, showing up in the endoscopy suite, and consistently doing excellent work shaped his trajectory. Together, they walk through how to think about competitiveness, building a portfolio (clinical performance, procedural exposure, research, and leadership), and how to strategically approach the ASGE Advanced Endoscopy Match—from choosing programs and asking for letters to understanding program culture, case volumes, and general GI expectations. They also dive into wellness, boundaries, and the “human side” of a very long training road, including protecting physical health, finding community, and keeping hobbies alive. Dan closes with concrete advice for residents and fellows: be present, do excellent work, say yes early in your career, and leverage mentors who genuinely want to see you succeed. This is a practical, candid roadmap for anyone seriously considering a career in advanced endoscopy.   https://www.asge.org/home/education-meetings/training-trainees/advanced-endoscopy-fellowship-(aef)

    Episode 38: The one where I speak to Jeremy Starkweather and Jason Ylizarde, co-creators of the Dragonfly Cholangioscope

    This conversation traces Dragonfly from an idea “in the back of a cab” to a clinically focused cholangioscopy platform that rotates through the biopsy channel for predictable, millimeter-level control. We delve into the mechanics (≈1.7 mm channel supporting 1.5 mm forceps and 4.5 Fr EHL), exploring how the catheter’s suppleness and internal rigidity enhance distal duct stability and device passability, and why micro-movements and neutral ergonomics are crucial for case efficiency. We map where cholangioscopy shifts the algorithm—medium/large stones, altered anatomy, tight distal duct work, and stricture evaluation with larger bites—and talk learning curve (~3–5 cases), setup tips, and the Medtronic distribution partnership. Finally: adoption math, fair-use evaluations despite contracting realities, and a look toward accessory innovation and AI-aided visualization. Key takeaways Rotation-first control → faster targeting, less wall fighting, better stability in tight anatomy. Larger working channel enables bigger biopsies and higher-energy lithotripsy. Aim for complete fragmentation in session one; repeat procedures should be the exception. Ergonomics: neutral hand position and micro-movements reduce fatigue. Practical adoption requires training support and a fair, multi-case evaluation window.
