Purpose: Literature on outcomes after SSRF, stratified for rib fracture pattern is scarce in patients with moderate to severe traumatic brain injury (TBI; Glasgow Coma Scale ≤ 12). We hypothesized that SSRF is associated with improved outcomes as compared to nonoperative management without hampering neurological recovery in these patients.

Methods: A post hoc subgroup analysis of the multicenter, retrospective CWIS-TBI study was performed in patients with TBI and stratified by having sustained a non-flail fracture pattern or flail chest between January 1, 2012 and July 31, 2019. The primary outcome was mechanical ventilation-free days and secondary outcomes …

BACKGROUND

Outcomes after surgical stabilization of rib fractures (SSRF) have not been studied in patients with multiple rib fractures and traumatic brain injury (TBI). We hypothesized that SSRF, as compared with nonoperative management, is associated with favorable outcomes in patients with TBI.

METHODS

A multicenter, retrospective cohort study was performed in patients with rib fractures and TBI between January 2012 and July 2019. Patients who underwent SSRF were compared to those managed nonoperatively. The primary outcome was mechanical ventilation-free days. Secondary outcomes were intensive care unit length of stay and hospital length of stay, tracheostomy, occurrence of complications, neurologic outcome, …

Management Of Traumatic Subarachnoid Hemorrhage By The Trauma Service: Is Repeat Ct Scanning And Routine Neurosurgical Consultation Necessary?, Stephen W. Cooper, Kimberly B. Bethea, Trevor J. Skrobut, Rod G. Gerardo, Juan Torres-Reveron, Akpofure Peter Ekeh

Department of Surgery Faculty Publications

Subarachnoid hemorrhage (SAH) results frequently from traumatic brain injury (TBI). The standard management for these patients includes brief admission by the acute care surgery (trauma) service with neurological checks, neurosurgical consultation and repeat head CT within 24 hours to identify any progression or resolution. Recent studies have questioned the need for repeat CT imaging and specialty consultation in mild TBI. We reviewed patients with mild TBI specifically with isolated SAH to determine progression of the pathology and need for neurosurgical involvement. All patients with SAH secondary to mild TBI (Glasgow Coma Score (GCS) of 13-15) who presented over a 5-year …

Department of Surgery Faculty Publications

Case summary A 33-year-old woman was transferred from an outside hospital with a penetrating injury to her right chest. The patient was shot with a crossbow with the entry site to the right breast/chest and a transmediastinal trajectory. She was intubated prior to arrival due to difficulty breathing. Her vital signs remained stable and within normal limits, with good breath sounds, and no evidence of pneumothorax on chest X-ray. The tip of the bolt was palpable at the patient’s left midaxillary line. Chest X-ray in trauma bay showed the transmediastinal trajectory, and the bolt appeared to have a field point …

Staged Reconstruction Of The Inferior Vena Cava After Gunshot Injury, Nathan M. Droz, John K. Bini, Kamran A. Jafree, John H. Matsuura

Department of Surgery Faculty Publications

A 23-year-old man with a gunshot injury to the abdomen and cardiac arrest requiring emergency department thoracotomy had a transection of the distal inferior vena cava (IVC) and small bowel injury. Because of persistent hemorrhagic shock, the IVC was ligated. During the next 3 days, he developed worsening bilateral leg edema. He was taken back for reanastomosis of his small bowel and reconstruction of the IVC using autologous femoral vein harvested from the right leg. We think that patients requiring ligation of the vena cava with worsening leg edema can benefit from a staged reconstruction of the IVC.

A Randomized 2x2 Factorial Clinical Trial Of Renal Transplantation: Steroid-Free Maintenance Immunosuppression With Calcineurin Inhibitor Withdrawal After Six Months Associates With Improved Renal Function And Reduced Chronic Histopathology, R. Brian Stevens, Kirk W. Foster, Clifford D. Miles, Andre C. Kalil, Diana F. Florescu, John P. Sandoz, Theodore H. Rigley, Tamer Malik, Lucile E. Wrenshall

Department of Surgery Faculty Publications

Introduction

The two most significant impediments to renal allograft survival are rejection and the direct nephrotoxicity of the immunosuppressant drugs required to prevent it. Calcineurin inhibitors (CNI), a mainstay of most immunosuppression regimens, are particularly nephrotoxic. Until less toxic antirejection agents become available, the only option is to optimize our use of those at hand.

Aim

To determine whether intensive rabbit anti-thymocyte globulin (rATG) induction followed by CNI withdrawal would individually or combined improve graft function and reduce graft chronic histopathology–surrogates for graft and, therefore, patient survival. As previously reported, a single large rATG dose over 24 hours was well-tolerated …

Irreversible Electroporation Of Malignant Lesions: An Institution Experience, Benjamin Bates, Minia Hellan, Shannon Kauffman, James R. Ouellette

Department of Surgery Faculty Publications

Background: Irreversible electroporation (IRE) is a tumor ablation technique where short, high-voltage pulses are applied to tumors to permeabilize the cell membranes. Since no thermal energy is created, it can be used near vital structures. We report our experience in a wide array of anatomic locations and on diverse oncologic processes.

Methods: We performed a retrospective review of all IRE cases performed at our institution from September 2010 to September 2013. Patients were evaluated for peri-operative morbidity, mortality, and oncologic outcome.

Results: Twenty-seven patients underwent IRE during 16 laparotomies and 12 CT guided percutaneous procedures. Anatomic locations: 9 liver, 7 …

A Novel Approach Using Liquid Embolic Agent For The Treatment Of Pancreatic-Cutaneous Fistulas: Report Of A Case, Amye M. Farag, Priti Parikh, Tamer Malik, Shannon L. Kauffman

Department of Surgery Faculty Publications

Pancreatic fistula formation remains one of the most dreadful complications after pancreaticoduodenectomies, resulting in extended hospital stays, increased healthcare costs, along with significantly increased morbidity and mortality. Little is mentioned in the literature about the use of percutaneous techniques to resolve this complication when conservative treatments fail. Thus, we developed a novel technique for treating pancreatic-cutaneous fistulas that develop post-pancreaticoduodenectomy. This work describes a novel approach of using a liquid embolic agent to treat a high-output pancreatic-cutaneous fistula after a Whipple procedure, which to the best of our knowledge after extensive literature searches, has not been performed before.

Identification Of A Cytotoxic Form Of Dimeric Interleukin-2 In Murine Tissues, Lucile E. Wrenshall, Suzanne E. Clabaugh, David R. Cool, Prakash Arumugam, William C. Grunwald Jr., Deandra R. Smith, Gino C. Liu, John D. Miller

Department of Surgery Faculty Publications

Interleukin-2 (IL-2) is a multi-faceted cytokine, known for promoting proliferation, survival, and cell death depending on the cell type and state. For example, IL-2 facilitates cell death only in activated T cells when antigen and IL-2 are abundant. The availability of IL-2 clearly impacts this process. Our laboratory recently demonstrated that IL-2 is retained in blood vessels by heparan sulfate, and that biologically active IL-2 is released from vessel tissue by heparanase. We now demonstrate that heparanase digestion also releases a dimeric form of IL-2 that is highly cytotoxic to cells expressing the IL-2 receptor. These cells include “traditional” IL-2 …

Traumatic Axillary Artery Pseudoaneurysm Treated With Intravascular Balloon Occlusion And Percutaneous Thrombin Injection, Maria Carratola, Priti Parikh, Kathryn M. Tchorz, Shannon Kauffman

Department of Surgery Faculty Publications

Axillary artery pseudoaneurysms are relatively rare, with few reported cases found in the literature. Furthermore, treatment with percutaneous thrombin injection has not yet been reported. We report the case of a 59-year-old man with a large (10 cm) post-traumatic pseudoaneurysm of the left axillary artery found five weeks after a motorcycle crash. The patient sustained multiple injuries, including fractures of the left scapula and clavicle. Edema was observed at the time of diagnosis. Arteriography with successful ultrasound-guided percutaneous thrombin injection was undertaken. The patient experienced no complications after the procedure.

To aid in the care of this patient population, knowledge of the disease process and current standards of therapy is paramount for healthcare providers.The future care of these patients and improvement from our existing standards hinges on the active translational research. To implement new technologies and advances in the treatment of PAD-induced wounds and ensure adequate utilization of our current therapies a PAD-wound team is necessary.

Early Prediction Of Trauma Patient Discharge Disposition, Ronald Beaulieu, Priti Parikh, Akpofure Peter Ekeh, Ronald J. Markert, Mary C. Mccarthy

Department of Surgery Faculty Publications

Objective: Do pre-injury and early hospital admission characteristics help predict patient discharge disposition? Background: Total one-year treatment cost of adult major trauma in the United States is estimated at $30 billion annually, with 58% of the cost due to the index hospitalization. Increased length of stay (LOS) increases morbidity and delays rehabilitation. Prediction of discharge to a location other than home through univariate risk factor methodology and development of a multivariable binary logistic regression model allows early discharge planning. Methods: A one-year Level 1 trauma center registry dataset was used to develop a predictive model of discharge disposition using 2836 …

Hemodialysis Access: Initial Considerations And The Difficult Patient, Laura Peterson, Maria Litzendorf, Hooman Khabiri, Stanislaw P. Stawicki

Department of Surgery Faculty Publications

The population requiring hemodialysis (HD) in the United States continues to grow, with recent studies reporting over 370,000 Americans with end stage renal disease (ESRD) who are HD-dependent. The creation of functional HD access is often the limiting step in utilization of renal replacement therapy (RRT). Since the 1960s, the creation of hemodialysis access has become one of the most commonly performed procedures in the United States with over 500,000 vascular access procedures performed per year. This represents approximately 8% of the annual Medicare budget allocated to patients with ESRD. The magnitude of the associated economic and human costs is …
