Thoracoscopy In Children: Is A Chest Tube Necessary?, Todd A. Ponsky, Steven S. Rothenberg, Kuojen Tsao, Daniel J. Ostlie, Shawn D. St Peter, G W. Holcomb Iii

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Historically, a chest tube or drain has been left following a thoracic operation to allow drainage of air or fluid in the postoperative period. However, in patients undergoing thoracoscopy, the tube is often the greatest source of postoperative pain. We began excluding chest tubes several years ago and therefore are reviewing our experience to evaluate the safety and efficacy of this approach.

METHODS: A retrospective review of the medical record was performed on patients undergoing thoracoscopy at two centers from 1993 to 2007. Patients who left the operating room without a chest tube were included in this series. Patient …

Coronary Steal Syndrome After Coronary Artery Bypass For Anomalous Aortic Origin Of A Coronary Artery., Benjamin A. Youdelman, Glenn J. Pelletier, C Igor Mesia, Marshall L. Jacobs

Department of Surgery Faculty Papers

Anomalous aortic origin of a coronary artery found in a symptomatic 9-year-old boy was initially treated with coronary artery bypass grafting using a left internal mammary artery anastomoses to the left anterior descending coronary artery, but resulted in coronary ischemia, likely from a steal phenomenon. Subsequent transection of the proximal left internal mammary artery with anastomosis to the ascending aorta, and coronary ostial enlargement, resulted in a durable treatment. We recommend caution in choosing coronary artery bypass grafting using a left internal mammary artery pedicle graft for the treatment of anomalous aortic origin of a coronary artery.

Iatrogenic Bile Duct Injury Associated With Anomalies Of The Right Hepatic Sectoral Ducts: A Misunderstood And Underappreciated Problem, Nitin Babel, Sujit Vijay Sakpal, Prakash Paragi, Jason Wellen, Stephen Feldman, Ronald Scott Chamberlain

Department of Surgery

Although laparoscopic cholecystectomy (LC) has been widely accepted as the standard of care, it continues to have a higher complication rate than open cholecystectomy. Bile duct injury with LC has often been attributed to surgical inexperience, but it is also clear that aberrant bile ducts are present in a significant number of patients who sustain biliary injuries during these procedures. We present three cases of right sectoral hepatic duct injuries which occurred during LC and provide a discussion of the conditions which are likely to lead to these injuries, as part of a strategy to prevent them.

Rhizopus Necrotizing Fasciitis Of Caesarean Wound: A Rare Life Threatening Condition, Abdul Rehman Alvi, Ghina Shamsi

Section of General Surgery

Mucormycosis is a rare cause of necrotizing fasciitis in immunocompromised patients. We report a young female, who developed rhizopus necrotizing fasciitis of caesarean wound. The lady died secondary to non-responding sepsis and irreversible multi-organ failure. High index of suspicion can lead to early diagnosis by frozen section of histopathology and fungal culture technique. Aggressive surgical debridement and intravenous anti-fungal medication is the main stay of treatment. A delay in diagnosis and treatment may cause multi-organ failure leading to high mortality.

Non-Traumatic Right Hepatic Artery Pseudoaneurysm: An Unusual Cause Of Hemobilia And Obstructive Jaundice, Abdul Rehman Alvi, Shahida Bibi, Ziaur Rehman, Salma Khan

Section of General Surgery

Most hepatic artery pseudoaneurysms (HAPA) are post traumatic, and non-traumatic pseudoaneurysm is rarely reported. It is a potentially life threatening vascular disorder and difficult to diagnose before rupture. Early diagnosis and prompt nonoperative intervention of this lesion could be life saving. The authors report the case of a patient with hemobilia caused by ruptured right hepatic artery pseudoaneurysm and subsequently developed right hepatic duct stricture, which has not been reported previously. This patient was successfully treated with endovascular stent graft of pseudoaneurysm and endoscopic stenting of right hepatic duct stricture.

Microrna Expression Profiling Of Male Breast Cancer., Matteo Fassan, Raffaele Baffa, Juan P Palazzo, Joshua Lloyd, Marco Crosariol, Chang-Gong Liu, Stefano Volinia, Hannes Alder, Massimo Rugge, Carlo M Croce, Anne Rosenberg

Department of Urology Faculty Papers

INTRODUCTION : MicroRNAs (miRNAs) are a class of small noncoding RNAs that control gene expression by targeting mRNAs and triggering either translation repression or RNA degradation. Their aberrant expression may be involved in human diseases, including cancer. To test the hypothesis that there is a specific miRNA expression signature which characterizes male breast cancers, we performed miRNA microarray analysis in a series of male breast cancers and compared them with cases of male gynecomastia and female breast cancers. METHODS : Paraffin blocks were obtained at the Department of Pathology of Thomas Jefferson University from 28 male patients including 23 breast …

The Efficacy Of Surgical Decompression Before 24 Hours Versus 24 To 72 Hours In Patients With Spinal Cord Injury From T1 To L1--With Specific Consideration On Ethics: A Randomized Controlled Trial., Vafa Rahimi-Movaghar, Soheil Saadat, Alexander R Vaccaro, Seyed Mohammad Ghodsi, Mohammad Samadian, Arya Sheykhmozaffari, Seyed Mohammad Safdari, Bahram Keshmirian

Department of Neurosurgery Faculty Papers

BACKGROUND: There is no clear evidence that early decompression following spinal cord injury (SCI) improves neurologic outcome. Such information must be obtained from randomized controlled trials (RCTs). To date no large scale RCT has been performed evaluating the timing of surgical decompression in the setting of thoracolumbar spinal cord injury. A concern for many is the ethical dilemma that a delay in surgery may adversely effect neurologic recovery although this has never been conclusively proven. The purpose of this study is to compare the efficacy of early (before 24 hours) verse late (24-72 hours) surgical decompression in terms of neurological …

Thoracoscopic Decortication Vs Tube Thoracostomy With Fibrinolysis For Empyema In Children: A Prospective, Randomized Trial., Shawn D. St Peter, Kuojen Tsao, Troy L. Spilde, Scott J. Keckler, Christopher J. Harrison, Mary Anne Jackson, Susan W. Sharp, Walter S. Andrews, Douglas C. Rivard, Frank P. Morello, G W. Holcomb Iii, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Management of empyema has been debated in the literature for decades. Although both primary video-assisted thoracoscopic surgery (VATS) and tube thoracostomy with pleural instillation of fibrinolytics have been shown to result in early resolution when compared to tube thoracostomy alone, there is a lack of comparative data between these modes of management. Therefore, we conducted a prospective, randomized trial comparing VATS to fibrinolytic therapy in children with empyema.

METHODS: After Institutional Review Board approval, children defined as having empyema by either loculation on imaging or more than 10,000 white blood cells/microL were treated with VATS or fibrinolysis. Based on …
