Join us for the 5th episode of our joint Journal Club series with Annals of Surgery. This time our guest is Dr. Mark Besselink, Professor at the University of Amsterdam and founder of the Dutch Pancreatic Cancer Study Group.    He led two new, practice-changing studies on laparoscopic distal pancreatectomy:    1) DIPLOMA, an observational study of laparoscopic vs. open distal pancreatectomy for pancreatic cancer focusing on oncologic outcomes: https://journals.lww.com/annalsofsurgery/Abstract/publishahead/Minimally_Invasive_versus_Open_Distal.95844.aspx   2) LEOPARD, a randomized controlled trial of laparoscopic vs. open distal pancreatectomy for any disease type: https://journals.lww.com/annalsofsurgery/Abstract/publishahead/Minimally_Invasive_Versus_Open_Distal.95444.aspx    Join us as we discuss the findings of these studies, the learning curve for advanced surgical techniques, and why the Dutch are just so good at surgical clinical trials.
