Behind The Knife: The Surgery Podcast

You have a young patient with a horseshoe abscess. How should you address the abscess initially? What is the best approach to drain it? Now that it is drained, what do I do with all the drains? Tune in to figure out how to best approach the most challenging of perianal abscesses.  Join Drs. Peter Marcello, Jonathan Abelson, Tess Aulet and special guest Dr. Julia Saraidaridis as they discuss the management of horseshoe abscess and complicated perianal fistula.  Learning Objectives 1. Describe the evaluation for perianal abscesses and fistula.  2. Discuss the different surgical options in managing horseshoe abscesses and post operative care to definitive management 3. Explain the rationale behind use of different fistula surgeries in complex perianal fistulas Link to episode video: https://behindtheknife.org/video/clinical-challenges-in-colorectal-surgery-management-of-horseshoe-abscess/ Please visit https://behindtheknife.org to access other high-yield surgical education podcasts, videos and more.  Our Colorectal Surgery Oral Board Audio Review includes 51 high-yield scenarios designed for Colorectal Surgeons by Colorectal Surgeons.  Learn more here: https://behindtheknife.org/premium

To close or not to close - that is the question!  Internal hernias following bariatric surgery can be a vexing source of delayed postoperative morbidity.  Join Drs. Matthew Martin, Kunoor Jain-Spangler, Adrian Dan, and Vincent Cheng for this EXCELLENT Journal Review in Bariatric Surgery.   Article #1: Stenberg 2023 - Long-term Safety and Efficacy of Closure of Mesenteric Defects in Laparoscopic Gastric Bypass Surgery Two mesenteric defects are created during Roux-en-Y gastric bypass (RNYGB) Petersen’s Defect Jejuno-jejunostomy mesenteric defect  Consensus does not exist regarding the standard of care for mesenteric defect closure (e.g., closure of one or both defects, material used for closure).  Risks of leaving defects open: internal herniation with or without bowel ischemia  Risks of closing defects Kinking the bowel (especially near the jejunojejunostomy) leading to obstruction  Chronic abdominal pain This article discusses a randomized controlled trial of obese patients undergoing bariatric RNYGB Randomized into two groups: a closure group and a non-closure group  Followed patients for 10 years with 95-96% follow up rate Results analyzed using a Cox proportional hazards regression that included risk factors like BMI, total weight loss at 1 year after surgery, and the other  Highlighted outcomes  Within the first 30 postop days, there was a higher rate of SBO in the closure group (1.3%) compared to the non-closure group (0.2%). This was attributed to kinking of the jejunojejunostomy  After 30 postop days and up to 10 years, reoperation rates for SBO were higher in the non-closure group (14.9%) compared to the closure group (7.8%). This trend was consistent regarding each site of mesenteric defect.  No significant differences between the two groups regarding chronic opioid use as a metric of chronic abdominal pain. Article #2: Nawas 2022 - The Diagnostic Accuracy of Abdominal Computed Tomography in Diagnosing Internal Herniation Following Roux-en-Y Gastric Bypass Surgery Unless there is an indication to immediately operate on a RNYGB patient in whom internal herniation is suspected, computed tomography (CT) is the recommended diagnostic test This article is a meta-analysis of 20 studies published between 2007 and 2020 that analyzed the accuracy of CT or detecting internal hernias in adult patients who underwent RNYGB for morbid obesity. A collective total of 1,637 patients were included.   Accuracy was determined by comparing diagnostic CT with exploratory surgery or the combination of negative CT and a negative 90 days follow-up Internal herniation was defined as presence of herniated small bowel with or without obstruction or ischemia through a visible opening at the mesenteric defect Results Pooled sensitivity of CT was 82% and specificity was 85% Positive predictive value of CT was 83% and negative predictive value was 86% CT signs with the highest sensitivity (sensitivity of finding)  Venous congestion (79%) Swirl sign (78%)  Mesenteric edema (67%) 15% risk of an internal hernia even with a negative CT scan In conclusion, CT can provide useful information, but these are just additional data points to consider in the overall evaluation of a patient. Surgeons should still have a low threshold for diagnostic laparoscopy even with negative CT findings If you liked this episode, check out other bariatric episodes here: https://behindtheknife.org/podcast-category/bariatric/ Please visit https://behindtheknife.org to access other high-yield surgical education podcasts, videos and more.

Surgical residency is hard. In some ways, intern year may be the hardest. We’ve been there. We’re a group of surgical residents formally known as the Collaboration of Surgical Education Fellows (CoSEF), a multi-institutional organization of surgical education research fellows working together to foster peer mentorship, networking, and scholarly collaboration. We’ve collectively reflected on our experiences as surgical interns across the country. Join Drs. Ananya Anand, Joe L’Huillier, and Rebecca Moreci as they discuss three tips for thriving as a surgical intern.  Hosts: –Dr. Ananya Anand, Stanford University, @AnanyaAnandMD –Dr. Joseph L’Huillier, University at Buffalo, @JoeLHuillier101 –Dr. Rebecca Moreci, Louisiana State University, @md_moreci –COSEF: @surgedfellows Learning Objectives:  Listeners will:  – List CoSEF’s three tips for thriving as a surgical intern – Challenge their definition of patient ownership – Recall the “Golden Rule” of treating others how you want to be treated – Appreciate the importance of self-care in surgical residency  References:  L’Huillier, Joseph C.

For patients with insufficient future liver remnant (FLR) volume, adequate hypertrophy after Portal Venous Embolization (PVE) is associated with reduced likelihood of post-operative hepatic insufficiency. But what happens when PVE isn’t enough to obtain adequate volume prior to surgery? In this episode from the HPB team at Behind the Knife, listen in on the discussion about advances in venous deprivation techniques that can potentially increase resection rates and hypertrophy  Hosts Anish J. Jain MD (@anishjayjain) is a T32 Research Fellow at the University of Texas MD Anderson Cancer Center within the Department of Surgical Oncology. Timothy E. Newhook MD, FACS (@timnewhook19) is an Assistant Professor within the Department of Surgical Oncology. He is also the associate program director of the HPB fellowship at the University of Texas MD Anderson Cancer Center.  Jean-Nicolas Vauthey MD, FACS (@VautheyMD) is Professor of Surgery and Chief of the HPB Section, as well as the Dallas/Fort Worth Living Legend Chair of Cancer Research in the Department of Surgical Oncology at The University of Texas MD Anderson Cancer Center Learning Objectives: - Develop an understanding of Portal Venous Embolization (PVE)  - Develop an understanding of Sequential Hepatic Venous Embolization (HVE) - Develop an understanding of Radiological Simultaneous Porto-hepatic Venous Embolization (RASPE) - Develop an understanding of the traditional two-stage hepatectomy with PVE - Develop an understanding of the Fast Track Two-Stage Hepatectomy Papers Referenced (in the order they were mentioned in the episode): 1) Niekamp AS, Huang SY, Mahvash A, Odisio BC, Ahrar K, Tzeng CD, Vauthey JN.
