Ethical issues in organ procurement: donation after normothermic regional perfusion in liver transplantation.

PURPOSE OF REVIEW: With ongoing organ shortages, new perfusion technologies are being embraced to help fill the unmet requirement. Improvement in utilization of donation after cardiac death (DCD) donors has the potential to greatly expand the pool of usable liver allografts. Normothermic regional perfusion (NRP) has been shown to increase usage of DCD donors and improve recipient outcomes. Yet, there remains heterogeneity in its usage worldwide. RECENT FINDINGS: Results from the first US multicenter study show improved biliary outcomes with NRP, consistent with prior data from Europe. Internationally, there are wide variations in DCD and NRP usage, highlighting the opportunities for improvement and increased utilization. The ethics of this technique continue to be considered. SUMMARY: NRP is a sound technique that can improve utilization for DCD donors, thereby increasing organ supply. Its usage is increasing worldwide. New data continue to show the benefit of this procurement strategy. NRP agrees with the principles of ethics.

Evaluation of a multidisciplinary, multimodal pain management protocol following pancreas transplantation.

INTRODUCTION: Patients undergoing solid-organ transplantation demonstrate pain arising from both the surgical intervention and pre-existing comorbidities. High levels of opioid use both pre- and post-transplant are associated with unfavorable transplant outcomes. Patient education, multimodal therapy, and discharge planning have all been demonstrated to reduce opioid use after transplant. METHODS: This is a single-center, retrospective study analyzing patients before and after implementation of a multimodal, multidisciplinary pain management protocol. Morphine milligram equivalents (MMEs) use during the index transplant hospitalization and the need for opioids at discharge was compared between the pre- and post-protocol groups. RESULTS: A total of 52 patients were included in the study, 31 in the pre and 21 in the post-protocol groups. Inpatient MME use was reduced from 135.5 to 67.5 MMEs after protocol implementation. Additionally, the number of patients discharged on opioids following transplant decreased from 90.3% to 47.6%. Pain scores, length of stay (LOS), and return of bowel function was not different between groups. CONCLUSION: The implementation of a multimodal, multidisciplinary pain management protocol significantly decreased opioid use during the post-surgical hospitalization and in the 6 months following transplantation. A combination of non-opioid analgesics, patient education, and discharge planning can be beneficial elements in pancreas transplant pain management.

Barriers to implementation of the FUSE program.

INTRODUCTION: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) developed The Fundamental Use of Surgical Energy (FUSE) Program to promote safe use of energy devices in the operating room and endoscopy suite. Utilization of the program has been slower than anticipated. This study aims to determine the barriers to implementing FUSE. METHODS: An anonymous survey was distributed to a surgery department at an academic teaching hospital (n = 256). Participants indicated their level of training. Answers were measured using a 5-point Likert scale. RESULTS: There were 94 (36.7%) respondents to the survey from September 7 to 20, 2016. Fifteen surveys were incomplete, leaving 79 responses for analysis. Most respondents were at the faculty level (45/79, 57.0%). The majority had heard of FUSE (62/79, 78.5%), but only 19 had completed the certification (19/62, 32.3%). There was no difference in the completion rate between faculty and trainees (26.7 vs. 20.6%, OR 1.4, 95% CI 0.49-4.06, p = 0.53). The most common reasons for not taking the exam were lack of time to study (26/43, 60.5%) and lack of time to take the exam (28/43, 62.1%); however, cost was not a barrier (12/43, 27.9%). The majority identified a personal learning gap regarding the safe use of surgical energy (30/43, 69.7%). Of the 19 FUSE-certified respondents, reasons cited for completing the exam included wanting to prevent adverse events to patients and in the operating room (17/19, 89.5% and 17/19, 89.5%), and the belief that the course would make them a safer surgeon (16/19, 84.2%). CONCLUSIONS: FUSE teaches the proper use of radiofrequency energy, how to prevent unnecessary injury, and promotes safe practice. Close to three out of every four surgeons self-identified a personal knowledge gap regarding the safe use of surgical energy. Time restraints were cited most commonly as the barrier to starting and completing FUSE. Integrating the FUSE program into resident educational conferences, faculty grand rounds, or national conferences may help improve participation and drive adoption of FUSE certification.

Utility of Chest Computed Tomography after a "Normal" Chest Radiograph in Patients with Thoracic Stab Wounds.

Chest computed tomography (CCT) is used to screen for injuries in hemodynamically stable patients with penetrating injury. We aim to determine the incidence of missed injuries detected on CCT after a negative chest radiograph (CXR) in patients with thoracic stab wounds. A 10-year retrospective review of a Level I trauma center registry was performed on patients with thoracic stab wounds. Patients who were hemodynamically unstable or did not undergo both CXR and CCT were excluded. Patients with a negative CXR were evaluated to determine if additional findings were diagnosed on CCT. Of 386 patients with stab wounds to the chest, 154 (40%) underwent both CXR and CCT. One hundred and fifteen (75%) had a negative screening CXR. CCT identified injuries in 42 patients (37%) that were not seen on CXR. Pneumothorax and/or hemothorax occurred in 40 patients (35%), of which 14 patients underwent tube thoracostomy. Two patients had hemopericardium on CCT and both required operative intervention. Greater than one-third of patients with a normal screening CXR were found to have abnormalities on CCT. Future studies comparing repeat CXR to CCT are required to further define the optimal diagnostic strategy in patients with stab wounds to chest after normal screening CXR.

Core needle biopsy is a safe and accurate initial diagnostic procedure for suspected lymphoma.

BACKGROUND: Excisional biopsy is currently recommended for the analysis of lymphadenopathy suspicious for lymphoma. This study aims to evaluate the efficacy and safety of image-guided core needle biopsy (IGCNB) for the diagnosis of lymphoma using a standard protocol for tissue acquisition and analysis. METHODS: All IGCNBs from 2008 to 2014 performed under the study protocol were included in analysis. Demographics, pathology results, additional studies, and follow-up information were recorded. RESULTS: Seventy-three IGCNBs were performed in 71 consecutive patients. Lymphoma was diagnosed in 37 patients (51%). All 37 patients (100%) were subtyped and treated based on IGCNB results. The remaining 36 IGCNBs in 34 patients did not have subsequent diagnosis of lymphoma in a mean follow-up of 15 months (range, 0 to 54 months). There were no complications. CONCLUSIONS: IGCNB performed under a standard protocol is effective and safe and should be considered as an initial diagnostic tool for the evaluation of lymphadenopathy suspicious for lymphoma.

Effect of marijuana use on outcomes in traumatic brain injury.

Traumatic brain injury (TBI) is associated with significant morbidity and mortality. Several studies have demonstrated neuroprotective effects of cannabinoids. The objective of this study was to establish a relationship between the presence of a positive toxicology screen for tetrahydrocannabinol (THC) and mortality after TBI. A 3-year retrospective review of registry data at a Level I center of patients sustaining TBI having a toxicology screen was performed. Pediatric patients (younger than 15 years) and patients with a suspected nonsurvivable injury were excluded. The THC(+) group was compared with the THC(-) group with respect to injury mechanism, severity, disposition, and mortality. Logistic regression was used to determine independent associations with mortality. There were 446 cases meeting all inclusion criteria. The incidence of a positive THC screen was 18.4 per cent (82). Overall mortality was 9.9 per cent (44); however, mortality in the THC(+) group (2.4% [two]) was significantly decreased compared with the THC(-) group (11.5% [42]; P = 0.012). After adjusting for differences between the study cohorts on logistic regression, a THC(+) screen was independently associated with survival after TBI (odds ratio, 0.224; 95% confidence interval, 0.051 to 0.991; P = 0.049). A positive THC screen is associated with decreased mortality in adult patients sustaining TBI.
