The Interventional Endoscopist

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.

In this deep-dive, Mankanwal Sachdev explores how cholangioscopy moves us from fluoroscopic silhouettes to direct mucosal visualization—and why that changes diagnosis and therapy across indeterminate strictures, PSC dominant lesions, and difficult stones. We walk through the current platform landscape (SpyGlass™ DS2, eyeMAX™, and Dragonfly™), practical biopsy technique to improve yield, and real-world lithotripsy choices (EHL vs Holmium laser) with a focus on workflow, cost, and verification of clearance. We also look ahead to AI-assisted interpretation, robotic/telerobotic control, and how training is evolving with ESGE 2025 standards and ASGE/ACG guidance. If you’re building or refining a pancreatobiliary program, this episode offers an evidence-based framework you can put to work tomorrow. Key takeaways: Use cholangioscopy when results will change management; pair with EUS for maximal diagnostic yield. Standardize biopsy protocols and specimen handling with pathology. Choose energy based on stone density, access, and resources; confirm clearance by direct inspection. Build a training pathway (simulation + supervised volume) and consider tiered credentialing.

I am excited to share insights from the Interventional Endoscopist podcast featuring Dr. Sachin Wani! The discussion centered on Barrett's esophagus, and strategies to improve detection and risk stratification Key takeaways: • The rising incidence of esophageal adenocarcinoma makes early detection crucial. Yet, survival rates remain low, highlighting the need for improved strategies • PEEC and PEEN underscore the issue of missed lesions during endoscopy, emphasizing the need for high-quality exam. • PEEC (postendoscopy esophageal adenocarcinoma) refers to cancer detected before the next recommended surveillance endoscopy in patients with non-dysplastic Barrett's esophagus. • PEEN (postendoscopy esophageal neoplasia) is a composite endpoint of high-grade dysplasia or cancer detected before the next recommended surveillance exam • A high-quality endoscopic exam is paramount, including meticulous inspection, standardized classification, and advanced imaging techniques like chromoendoscopy. • A 10-step approach to a high-quality exam includes identifying landmarks, spending adequate time inspecting the Barrett's segment, cleaning the distal esophagus, and using high-definition white light endoscopy and virtual chromoendoscopy • While the Seattle biopsy protocol is standard, it has limitations due to sampling errors • WATS (Wide Area Transepithelial Sampling) can enhance neoplasia detection as an adjunct to the Seattle protocol by sampling the entire Barrett's segment. • AI (artificial intelligence) holds promise for lesion detection, improved diagnostic accuracy, and quality assessment of endoscopic exams. AI platforms may help identify visible lesions and predict histology, as well as assess the quality of the endoscopic examination. • The Tissue Cypher test can aid in risk stratification by analyzing biomarkers to predict the risk of progression to high-grade dysplasia. It can also predict prevalent high-grade dysplasia or cancer. • Dr. Wani also shared his journey into medicine, influenced by his family, and the challenges faced by foreign medical graduates. A key message was the importance of continuous improvement in endoscopic techniques and the integration of new technologies to combat esophageal adenocarcinoma This episode was sponsored by Castle Biosciences the makers of the TIssue Cypher Test.

🔵 As many of you know, March is Colon Cancer Awareness Month. To contribute to this important conversation, I decided to share my personal experience with a colonoscopy that took place two years ago. 🎧 In Episode 19 of my podcast, "The Interventional Endoscopist," aptly titled "The One Where I Talk About My Colonoscopy," I recount the details of my procedure, my feelings before and after, and why it's so crucial to get screened. My hope is that my personal experience can help dispel any fears and misconceptions about this life-saving procedure. Remember, prevention and early detection are key in the fight against colon cancer, and a colonoscopy is one of the most effective ways to ensure this. So, whether you're a physician, a patient, or someone interested in health and wellness, I invite you to listen to my candid conversation about this important topic. My decision to share this personal story was greatly inspired by Dr. Neil Parekh and his recent episode on "The Gut Doctor Podcast." where he discusses how he performed his colleague's procedure. Their discussion inspired and encouraged me to do the same, in hopes of dispelling fears and misconceptions around this life-saving procedure.
