Generate an evidence-based presentation on: "Totally robotic pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD): from biological tissue simulation to clinical practice." Target Audience: Surgical Oncologists, HPB Surgeons, and Clinical Fellows. Narrative Arc: Learning curve review and transition from simulation to live surgery. Please ensure the literature search explicitly retrieves and synthesizes: 1. The technical challenges of robotic PJ (e.g., duct-to-mucosa, modified Blumgart technique) and the risk factors for postoperative pancreatic fistula (POPF). 2. The specific role of advanced simulation using biological material (biotissue/animal models) to overcome the lack of haptic feedback in robotic surgery. 3. Validation metrics for competency assessment (such as modified OSATS scores or learning curve milestones). 4. Evidence on "skills transfer" and how structured biotissue training impacts clinical outcomes and patient safety during initial real-world robotic PD cases.
