Upon encountering a patient who develops an anastomotic leak after a straight-forward low anterior resection, you are taken aback, as the patient is healthy and has no apparent risk factors. This prompts you to consider whether the microbiota may have played a role in causing the leak.



Join Dr. Carole Richard, Dr. François Dagbert, Dr. Maher Al Khaldi, and Dr. Roy Hajjar in their conversation about the impact of gut microbiota on anastomotic healing and leak. 



Learning objectives 

- To list the known risk factors for anastomotic leak.

- To understand how preoperative gut microbiota influence anastomotic healing and could lead to leak.

In this episode our team dives into the diagnosis, workup and management of malignant pleural mesothelioma. Listen as we debate the pros and cons of surgical management of this disease with extrapleural pneumonectomy versus pleural decortication and discuss the nuances of choosing the right approach for the right patient.



Learning Objectives

- Describe the workup and staging of a patient with malignant pleural mesothelioma

- List the subtypes of malignant pleural mesothelioma, characteristics of resectable disease, and patient factors which impact surgical candidacy 

- Describe the approach to an extrapleural pneumonectomy and pleural decortication

- Analyze which surgical approach is best for various subsets of patients

- Describe the adjuvant treatment for malignant pleural mesothelioma

Clinical Challenges in Thoracic Surgery: Malignant Pleural Mesothelioma

Can appendicitis wait until the morning? Join Drs. Ashlie Nadler, Jordan Nantais, Graham Skelhorne-Gross, and Marika Sevigny from our Emergency General Surgery Team as they discuss the role of deferring appendectomies from overnight to the next morning.



Paper 1: Patel SV, Zhang L, Mir ZM, Lemke M, Leeper WR, Allen LJ, Walser E, Vogt K. Delayed Versus Early Laparoscopic Appendectomy for Adult Patients With Acute Appendicitis: A Randomized Controlled Trial. Ann Surg. 2024 Jan 1;279(1):88-93.

https://pubmed.ncbi.nlm.nih.gov/37436871/



-Non-inferiority randomized controlled trial comparing delayed appendectomy group with surgery taking place after 0600 the morning following a decision to operate versus the immediate appendectomy group with surgery taking place between 8pm and 4am and within 6 hours of a decision to operate



-A priori non-inferiority margin of 15% for 30-day complications



-Intention-to-treat analysis with risk difference -12% in favor of the delayed group (p < 0.001)



-Superiority as on per protocol analysis



-Underpowered at 91% due to early closure of study due to loss of reliable day time emergency triage operating time



Paper 2: Jalava K, Sallinen V, Lampela H, Malmi H, Steinholt I, Augestad KM, Leppäniemi A, Mentula P. Role of preoperative in-hospital delay on appendiceal perforation while awaiting appendicectomy (PERFECT): a Nordic, pragmatic, open-label, multicentre, non-inferiority, randomised controlled trial.

https://pubmed.ncbi.nlm.nih.gov/37717589/



-Non-inferiority randomized controlled trial comparing appendectomy within 8 hours versus 24 hours



-No difference in rate of perforation on intention-to-treat or per protocol analyses

Journal Review in Emergency General Surgery: Appendicitis

Before 1952, open heart surgery was considered science fiction. The heart was off limits to surgeons despite more than half a million Americans dying annually from heart disease. Doing nothing was the strategy. However, the status quo would soon change thanks to a few brave and imaginative surgeons who dared to break the most rigid of medical taboos: Do not touch the human heart. We sat down with Dr. Gerald Imber, author of the new book “Cardiac Cowboys: The Heroic Invention of Heart Surgery” to discuss how five men raced to invent an entirely new field of surgery. 



Guests:

Jessica Millar, MD- General Surgery Resident- University of Michigan; Education Fellow- Behind the Knife 

 Nick Teman, MD- Associate Professor of Cardiac Surgery and Critical Care- University of Virginia 

Gerald Imber- Assistant Clinical Professor of Plastic surgery at the Weill-Cornell Medical Center, Attending Surgeon at New York-Presbyterian Hospital, and Director of a private clinic in New York City, NY; Author of “Wendell Black, MD”, “Genius on the Edge: The Bizarre Double Life of Dr. William Stewart Halsted”, and “Cardiac Cowboys: The Heroic Invention of Heart Surgery”.
