Join us for our 7th joint Journal Club with Annals of Surgery. This time our guest is Dr. Chad Ball, a hepatobiliary and acute care surgeon and Associate Professor at the University of Calgary.    He has pioneered a new single-stage approach for walled off pancreatic necrosis, "surgical transgastric necrosectomy," described in this Annals paper:  https://journals.lww.com/annalsofsurgery/Abstract/publishahead/Surgical_Transgastric_Necrosectomy_for_Necrotizing.95399.aspx    Join us to learn more the range of approaches to this challenging problem and new, exciting techniques!   PS: For those interested, a video of laparoscopic transgastric necrosectomy can be found here: https://www.youtube.com/watch?v=VWPiaZpzAxQ
