Behind The Knife: The Surgery Podcast

Direct Peritoneal Resuscitation!  We’re not just dumping fluids into the open abdomen.  What is DPR?  Why do it?  Who should get it?  Does it work? Come try and stay awake for some basic science talk before then learning all about why you should consider adopting DPR into your Trauma/EGS practice? Join Drs. Cobler-Lichter, Kwon, Meizoso, Urréchaga, and Rattan as they guide you through all this and more!  Hosts: Michael Cobler-Lichter, MD, PGY2: University of Miami/Jackson Memorial Hospital/Ryder Trauma Center @mdcobler (twitter) Eva Urrechaga, MD, PGY6/R4: University of Miami/Jackson Memorial Hospital/Ryder Trauma Center @urrechisme (twitter) Eugenia Kwon, MD, Trauma/Surgical Critical Care Fellow: University of Miami/Jackson Memorial Hospital/Ryder Trauma Center Jonathan Meizoso, MD, MSPH Assistant Professor of Surgery, 3 years in practice University of Miami/Jackson Memorial Hospital/Ryder Trauma Center @jpmeizoso (twitter) Rishi Rattan, MD, Attending Surgeon in Trauma/Critical Care, 7 years in practice Legacy Emanuel Medical Center @DrRishiRattan (twitter) Learning Objectives: - State the proposed benefits of DPR - Identify who can benefit from DPR - Demonstrate the proper way to set up a DPR circuit - Discuss the proposed basic science mechanism for DPR’s efficacy Quick Hits: 1.      Consider DPR in all your open abdomens in EGS/Trauma.  You never know when you’re going to be able to close some of these patients. 2.     The principal of DPR is to allow the fluid to dwell in the abdomen as long as possible.  Keep the catheter deep and don’t put holes in your dressing. 3.     DPR is ideal for patients with packing, who are in discontinuity, and for fresh anastomoses.  These will only benefit from DPR, not be harmed by it.  4.     Make sure these patients are receiving hourly I/Os.  Nursing by-in is huge for this procedure. 5.     DPR is associated with higher rates of fascial closure, reduces inflammation, and improves blood flow to the abdomen.

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.
