You get consulted on a 34-year-old with ileocolic Crohn’s disease on Humira. You determine he needs surgery for recurrent partial obstructions. When do you do the surgery? How long should he be off his biologic medication? When to restart it post op? Join Drs. Abelson, Marcello and Aulet as they take us through two articles to help us figure it out!
Learning Objectives:
1.     Describe the complications of biologic medications in the peri-operative period
2.     List the different classifications of medications for Crohn’s disease
3.     Discuss the approach to managing timing of surgery for patients with crohn’s disease

Episode Title: Journal Review in Colorectal Surgery: Timing of Biologics and Surgery in the Setting of Crohn’s Disease
Want to learn more about achalasia and its procedural management? Excited about the POEM procedure?  Learn what the current literature says when it comes to recommending POEM or the tried-and-true Heller myotomy from the Swedish Thoracic surgery team.

Learning objectives
–        Review basics of achalasia
–        Discuss the current literature comparing POEM and Heller myotomy with fundoplication

The utilization of point-of-care ultrasound and other non-invasive cardiac output monitoring technologies varies because of knowledge, resource availability and cultural practices. In this  Clinical Challenge in Surgery episode from the Surgical Critical Care team at Behind the Knife, we provide a brief history of the use of cardiac-output monitoring in the ICU, introduce a few clinical scenarios in the context of point of care ultra-sound and other less-invasive cardiac-output monitoring technologies.
Learning Objectives: 
In this episode, we review the historical uses of central venous pressure monitoring, pulmonary-artery catheters and the more frequently utilized point-of-care-ultrasound (or POCUS) in managing complex ICU patients. We review the outcomes behind these technologies, describe the views and utility of POCUS, and introduce less-invasive or completely non-invasive ways to measure cardiac-output monitoring.
