Endoscopic Resection of Complex Duodenal Polyps

Gastroenterology & Endoscopy

In this episode of the Gastroenterology and Endoscopy podcast, we discuss a challenging case involving a pedunculated duodenal adenoma. These types of polyps present unique challenges for endoscopists, requiring meticulous planning for a successful procedure. The goal is to achieve a complete R0 resection, removing the entire lesion without leaving any microscopic remnants. We explore strategies to prevent migration of the polyp into the bowel, such as positioning the patient in a decubitus supine position or using an antimotility agent. The endoscopist and assistant must be on high alert to catch the polyp with the snare, and having a Roth's net on standby is recommended.

Quotes:

• 00:02:52 - "By allowing the neoplasm to float, we reduce the chances of transmitting electrosurgical current to the base of the lesion, minimizing the risk of perforation."
• 00:03:06 - "And when it comes to closing the wound post-resection, clips are a must."

Topics Discussed:

1. Introduction to Pedunculated Duodenal Adenoma: Brief description of the polyp’s location and importance of meticulous planning for resection.
2. Achieving Complete Resection (R0): Importance of removing the entire lesion and considerations to make during resection.
3. Preventing Polyp Migration: Strategies to prevent the polyp from moving into the distal bowel.
4. Complication Prevention: Discussion on measures to prevent complications during and after endoscopic resection.
5. Tools and Techniques: Exploration of various tools (snare, Roth’s net, distal transparent cap) and techniques (submucosal injection, underwater resection, use of endoloops and clips).
6. Managing Immediate and Delayed Bleeding: Importance of using endoscopic clips and hemostatic hydrogels, especially in patients on anticoagulation.
7. Proximity to the Papilla of Vater: Ensuring correct identification of the lesion’s location and planning the resection accordingly.
8. Post-procedure Care: Importance of starting proton pump inhibitors post-procedure.
9. Final Thoughts and Goodbye: Summing up the key takeaways from the episode and bidding farewell to the listeners.
