Expert live case documenting the complete management of a significant perforation following underwater polypectomy of a 30–35mm splenic flexure polyp. Running dual commentary narrates every decision — from haemostasis prioritisation and Kerr grasper use through to systematic high-density clip closure and real-time clip failure management.

This live case captures real-time identification and management of the Muscle Retraction Sign (MRS) during ESD of a biopsy-proven mid-oesophageal squamous cell cancer. Learn how directionality and asymmetric submucosal injection reveal deep SM invasion, how to navigate the EID intramuscular plane deliberately, and how to re-enter the submucosa to achieve a negative deep margin.

Expert live case teaching decision-making in complex polypectomy, featuring hybrid underwater ESD/EMR of a previously attempted duodenal lesion. Covers technique selection, intraoperative bleeding management with a systematic gravity-water-tamponade framework, and high-risk defect closure using mantis and retention clips. Includes candid discussion of when to transition from ESD knife to snare resection and the importance of patient positioning for optimal access.

Expert live case teaching piecemeal EMR of a large sessile transverse colon polyp, covering optical assessment with BLINK criteria, underwater and injection-assisted resection, intraprocedural bleeding management, and clip closure.

Watch the complete PRIME algorithm in action: from MRS detection and deep margin optical diagnosis to real-time EID plane selection. A 75-minute teaching case demonstrating how to achieve R0 resection in early rectal cancer with the REACT tool.
