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.

Wound Healing In Peripheral Arterial Disease: Current And Future Therapy, Jon C. Henry, Laura Peterson, Richard E. Schlanger, Michael R. Go, Chandan K. Sen, Robert S.D. Higgins

Wounds secondary to peripheral arterial disease (PAD) result in substantial morbidity and burden to the healthcare industry. 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 …

Intravenous Ascorbic Acid To Prevent And Treat Cancer-Associated Sepsis?, Thomas E. Ichim, Boris Minev, Todd Braciak, Brandon Luna, Ron Hunninghake, Nina A. Mikirova, James A. Jackson, Michael J. Gonzalez, Jorge R. Miranda-Massari, Doru T. Alexandrescu, Constantin A. Dasanu, Vladimir Bogin, Janis Ancans, R. Brian Stevens, Boris Markosian, James Koropatnick, Chien-Shing Chen, Neil H. Riordan

Department of Surgery Faculty Publications

The history of ascorbic acid (AA) and cancer has been marked with controversy. Clinical studies evaluating AA in cancer outcome continue to the present day. However, the wealth of data suggesting that AA may be highly beneficial in addressing cancer-associated inflammation, particularly progression to systemic inflammatory response syndrome (SIRS) and multi organ failure (MOF), has been largely overlooked. Patients with advanced cancer are generally deficient in AA. Once these patients develop septic symptoms, a further decrease in ascorbic acid levels occurs. Given the known role of ascorbate in: a) maintaining endothelial and suppression of inflammatory markers; b) protection from sepsis …

Portable Ultrasonography In Mass Casualty Incidents: The Caveat Examination, Stanislaw P. Stawicki, James M. Howard, John P. Pryor, David P. Bahner, Melissa L. Whitmill, Anthony J. Dean

Department of Surgery Faculty Publications

Ultrasonography used by practicing clinicians has been shown to be of utility in the evaluation of time-sensitive and critical illnesses in a range of environments, including pre-hospital triage, emergency department, and critical care settings. The increasing availability of light-weight, robust, user-friendly, and low-cost portable ultrasound equipment is particularly suited for use in the physically and temporally challenging environment of a multiple casualty incident (MCI). Currently established ultrasound applications used to identify potentially lethal thoracic or abdominal conditions offer a base upon which rapid, focused protocols using hand-carried emergency ultrasonography could be developed. Following a detailed review of the current use …

Bleeding Meckel’S Diverticulum In A 4-Month-Old Infant: Treatment With Laparoscopic Diverticulectomy. A Case Report And Review Of The Literature, J. Rainer Poley, Thomas E. Thielen, Jeffrey C. Pence

Department of Surgery Faculty Publications

A bleeding Meckel’s diverticulum is presented in a 4-month-old African American infant. This event is rare at this age, and our patient is only the second 4-month-old infant reported in the English literature. The infant presented with painless frank rectal bleeding, the blood being maroon-colored, and clots were found in the diaper. There was also anemia, with an hemoglobin of less than 8 gm/dl. The color of the blood suggested a bleeding site in the ileocecal region, a Meckel’s diverticulum was suspected, which was then confirmed by an isotope scan. A typical Meckel’s diverticulum was found on laparoscopic surgery, was …

Interventional Options For Malignant Upper Gi Obstruction, 2nd Ed, James R. Ouellette, Lisa Patterson, Paula M. Termuhlen

Department of Surgery Faculty Publications

Background

Patients with unresectable cancers of the upper gastrointestinal tract often suffer severe symptoms due to pain, nausea and vomiting, weight loss, cachexia, and poor food tolerance. This can be related to gastric and duodenal cancers causing intrinsic obstruction of the intestinal lumen or pancreatic and biliary cancers causing extrinsic biliary compression. Management options vary depending on the site of obstruction, the patient’s functional status, the patient-defined goals of care, and estimated prognosis. Fast Fact #45 discussed medical management options. This Fact Fact reviews interventional approaches for upper GI obstructions, especially when further radiation, chemotherapy, medical management, or curative surgical …

Fracture Of The Scapula With Intrathoracic Penetration In A Skeletally Mature Patient, Cary C. Schwartzbach, Hani Seoudi, Amy E. Ross, Kimberly M. Hendershot, Linda Robinson, Alireza Maekzadeh

Department of Surgery Faculty Publications

To our knowledge, intrathoracic displacement of a fractured scapula has only been described in two reports involving adolescents^1,2. We present the case of a skeletally mature adult with a scapular fracture that penetrated the thoracic cage without causing a pneumothorax. We speculate as to how the adult scapula can deform in a manner consistent with this rare injury. As the patient had advanced Alzheimer disease, the family consented to the publication of data concerning this case.
