Behind The Knife: The Surgery Podcast

Calling all surgeons! It’s time to take back common bile duct stones! Join our surgical education fellow, Shanaz Hossain, as she talks about laparoscopic common bile duct exploration (LCBDE) with Drs. Maggie Bosley, Lucas Neff, and Byron Fernando Santos. Dr. Bosley is a graduating chief resident at Wake Forest and incoming MIS fellow at Washington University in St. Louis. Dr. Neff is an assistant professor of pediatric surgery with Wake Forest Baptist Health and Brenner’s Children’s Hospital. Dr. Santos is an assistant professor of surgery at Dartmouth-Hitchcock Medical Center. As a research resident at Northwestern University, he co-invented a LCBDE simulator that is used to train surgeons in these techniques. He is also a member of the SAGES Safe Cholecystectomy Task Force and has led numerous LCBDE courses.  Join us for a discussion on LCBDE indications, implementation, techniques, and tips for incorporation into patient care.

To operate or not to operate, to drain the urine leak or to not drain it, those are the questions. Join our Miami Trauma team including Drs. Urréchaga, Neeman, and Rattan- in their final episode together! - as they discuss how to navigate the ins and outs of renal trauma!  Learning Objectives:  ·       Define the different renal injury grades and how to manage each, ·       Identify when to take the renal trauma patient to the operating room, ·       Discuss when to involve IR for urinary drainage or embolization. ·       Explain when and how to perform a nephrectomy. ·       Debate the treatment of penetrating zone two injuries- to explore or not explore? Quick Hits: 1.     Most kidney injuries, the vast majority, can be non-operatively managed.  2.     For pretty much all AAST grade of injury, the choice to go to the OR immediately lies in whether the patient is stable or unstable.  3.     If there is a urinary leak seen on imaging, it can usually just be observed and followed with repeat imaging to determine the need for drainage, unless the injury is significant or if there is injury to the renal pelvis- then the patient will usually need a drainage procedure.  4.     Consider IR in any stable patient found to have active extravasation, fistula, or pseudoaneurysm. 5.     In the case of an unstable patient, except very rare circumstances, you should be going to the OR  6.     If there is another cause of instability, address that first. If you’re opening Gerota’s fascia, be prepared to commit to a nephrectomy.  7.     In penetrating injury, the formal teaching is mandatory exploration of a renal hematoma. Real world experience shows that this isn’t always necessary- such as in tangential injuries or injuries to the periphery- on a case-by-case basis.

Have a grand idea for how to improve education and patient safety in surgery, but unsure how to make it a reality? Perhaps the OR Black Box can inspire you and set you on your path as an innovator. We are joined by Dr. Teodor Grantcharov, one of its creators. The OR Black Box is a system that collects, stores, and analyzes a large amount of data from the operating room beyond just surgical video, such as video and audio of the operating room and patient physiology data. Using the system for feedback through self-directed review, coaching, and integrated AI analysis has changed the way we can learn and teach in surgery, and may have implications for the future of evaluation and credentialing.  Learning Objectives Listeners will describe the value that accessible data review and analysis adds to surgical education. Listeners will describe how review of operative data could be utilized for more objective evaluation and credentialing, and how this can be used for continuous improvement. Listers will recognize common barriers to using new technology or process changes in surgery. Listeners will recognize the importance of a well-developed research question and its application to a clinical need when designing research or innovation in surgery and education. Listeners will appreciate the long and iterative process required to go from a research idea to implementation and impact on clinical outcomes. Listeners will organize their own ideas for research utilizing the advice offered in the episode.  References: 1. Goldenberg MG, Jung J, Grantcharov TP.

Think about why you are in the OR. If its an elective situation and can wait, consider bailing. If its emergent, you may have to do something more definitive. Exposure may be a challenge, you may have to alter your typical approach including where the assistant grabs and retracts. Extra hands are helpful. Bleeding can be a big deal. If possible, map out the abdominal wall ahead of time with cross-sectional imaging.
