Surgery; Surgery - Vascular
The practice of vascular surgery has changed dramatically in the last decade, largely as a result of rapid adoption of technologic advances by most vascular surgeons, and I am proud and happy to be a part of this evolution. We the vascular surgeons do not consider ourselves as just surgeons, but "therapists" of vascular disease. This mainly stems from our better understanding of the natural history of vascular diseases, and their treatment. Our capability of doing both surgery and minimally-invasive procedures puts us in the best position on treat the millions of complicated patients with vascular disease. I am privileged to work with veterans with very complicated vascular problems, and we perform about 700 vascular and endovascular interventions yearly. My main areas of clinical and research interests are abdominal aortic aneurysms (esp. stent graft repair), limb salvage interventions (bypasses and angioplasty/stenting procedures), and carotid artery disease. I also have an interest in wound healing, and hold a wound clinic once a week. Hasan H. Dosluoglu, MD

Surgery - Laparoscopic; Surgery - Trauma; Surgical Critical Care - Surgery
I am an acute care surgeon board-certified in both surgery and surgical critical care, with clinical focus in trauma, emergency general surgery and surgical critical care. The most important part of my job is providing compassionate surgical care to my patients, who are often acutely injured and/or critically ill. I have a deep awareness of, and empathy for my patients’ suffering, and I do my best to alleviate it. I practice medicine with a golden rule — “Do unto others as you would have them do unto you”. I believe that an optimal medical decision is the one that integrates information about the patient’s clinical state and circumstances, the available research evidence, as well as the patient’s values and preferences. I also perform laparoscopic surgery, gastrointestinal surgery (small bowel, colorectal and biliary), complex hernia repair, endoscopy and provide wound care. My scholarly focus is in the area of trauma and critical care-related pathophysiology. In basic science, I was the first to demonstrate that food high in advanced glycation end-products (AGE) and its interaction with the receptor (RAGE) predispose patients for aspiration-induced acute respiratory distress syndrome (ARDS) in trauma. In clinical research, I have been pursuing interests in areas of utilization of imaging study in trauma, prevention of blood clot formation in head injury patients, ICU quality improvement. I was a co-investigator on NIH-funded grants for evaluation of aspiration biomarkers in trauma and surgery, as well as on an SIS multicenter study on duration of antibiotics for abdominal infection. I have mentored numerous surgical residents and medical students in research, which has led to them receiving national research awards. I have a bibliography of 50 peer-reviewed scientific publications and 6 book chapters, in addition to many oral and poster presentations. I am a member of the editorial review board for the Journal of Surgical Research, and an ad hoc reviewer for many leading journals. I have a passion for teaching medical students and residents. I find satisfaction in sharing my knowledge, experience and wisdom with those in the training phase of their careers. The trainees’ inquiries have helped me stay current in the field, and ultimately help me render the best care to my patients. As a surgeon, role model and mentor, I have inspired many medical students to pursue surgery as a career.
Surgery; Surgery - Vascular; Surgery - Endovascular
Dr. Harris has a national reputation for her work in the field of education, having served on the ACME Surgery Review Committee, the Vascular Surgery Milestone Project and is the past President for the Association of Program Directors in Vascular Surgery and Eastern Vascular Society. Her clinical interests include peripheral arterial disease, venous occlusive disease, dialysis access, thoracic outlet syndrome, aneurysmal disease and carotid disease. As a vascular surgeon, I am dedicated to treating and helping my patients manage conditions of the circulatory system, including diseases of the arteries, veins and lymph vessels and blood disorders that affect circulation. My patients can feel secure knowing I’m prepared to deliver the most advanced treatments available — including minimally invasive endovascular interventions, open vascular procedures and hybrid surgery techniques that combine open surgical and endovascular approaches. Vascular disease tends to be a lifelong problem; therefore, I aim to help my patients modify their lifestyles so that they experience as few vascular difficulties as possible throughout their lives. I have decades of experience researching venous disease, cerebrovascular disease, aneurysms, peripheral arterial disease (PAD) and thoracic outlet syndrome. I am committed to conducting outcomes-based research for conditions including PAD and aneurisms because my goal is to increase knowledge about the intermediate and long-term results of endovascular and vascular practices and interventions. While immediate results are important, long-term outcomes are even more important for vascular disease, as we cannot cure the conditions, but we can treat them. I work toward learning which treatments are most effective based on patients’ end results. As program director for both the vascular surgery residency and fellowship, I train the next generation of vascular surgeons to be preeminent members of the vascular surgical community. I believe that the better I prepare my medical students, residents and fellows, the more opportunities they have to positively affect a greater number of patients. My teaching covers all aspects of vascular disease; I teach trainees in clinics and the hospital setting and during angiographic procedures and open surgery. I strive to help professionals and trainees in my field stay abreast of emerging scientific research and clinical applications. That’s why I’ve co-directed and lead symposia for the Gates Vascular Institute (GVI) and Western New York Vascular Society — conferences enabling discussion about updates in cardiac, vascular and neuroendovascular medicine. It’s also why I am an adviser for the Vascular and Endovascular Surgery Interest Group, which provides faculty mentoring and support to medical students considering surgical fields. Further, teaching trainees is such an important part of my work that I became a certified educator through the Royal College of Physicians, an organization that has helped me enhance my teaching methods and learn educational techniques to help my mentees excel.
I have been Chief of Gastrointestinal Surgery and Professor of Oncology at Roswell Park Cancer Institute since April 2012. I did my residency at the NYU Medical Center Department of Surgery and both research and clinical fellowships at Memorial Sloan Kettering Cancer Center and I am a graduate of Johns Hopkins University with a MD from New York University School of Medicine. My research focuses on technical advances in minimally invasive esophageal and GI surgeries and developing new targets and agents for treatment of pancreatic and other GI cancers. I lead a funded laboratory program which focuses on glucose promotion of histidine signaling to drive cancer progression in the absence of growth factor stimulation. The goal is to target histidine signaling as novel therapy in GI cancer.
My current research interests and expertise are in the following areas: limb salvage for sarcomas and other tumors; node dissections in malignant melanoma; regional chemotherapy; debulking of disseminated abdominal tumors; intraperitoneal chemotherapy; intraoperative radiation; resection of difficult or unresectable tumors. 1)resection of difficult "unresectable" tumors which can be rendered resectable through special surgical techniques; e.g. retroperitoneal sarcoma limb preserving surgery and resection of extremity sarcomas. 20 surgical treatment of malignant melanoma, stages I-IV. Other research interestes: 1) Tumor Immunology; 2) Regional chemotherapy; 3) The development of a predictable, reliable chemosensityiveity assay in vitro.
Surgery; Transplantation; Surgery - Transplant
I conduct clinical outcomes research on hospital- and population-based data with a focus on donor selection, kidney transplantation outcomes, and delivery of high quality care. Over the last decade my research has focused on donor selection. In retrospective cohort studies of national and single center data I have examined outcomes of kidneys perceived to be suboptimal such as those declined by local centers and transplanted elsewhere, kidneys with prolonged cold ischemia time, small pediatric donor kidneys, dual kidney engraftments, kidneys with chronic lesions, donation after cardiac death donors, and donors with acute kidney injury in order to provide evidenced-based data on the magnitude of the risks associated with utilization of specific types of organs. As a result of these analyses, changes in perception of donor quality have resulted in increased kidney utilization at the centers where I have worked and invitations to share my work at other programs as well as national meetings. My research findings in this area have had a positive effect in the transplant realm since my work provides empiric evidence of acceptable outcomes of various types of kidneys that have traditionally been rejected, thus providing a basis for increased kidney utilization. With knowledge and expertise acquired through matriculation at the University of Michigan with a Masters in Clinical Research Design and Statistical Analysis I am able to analyze data myself or communicate effectively with a biostatistician. During the last 14 years I have either conducted or participated in 85 retrospective and 17 prospective studies of transplant outcomes.
Surgery - Vascular; Surgery - Endovascular
Clinical expertise: Endovascular & open surgical treatment of Peripheral arterial disease, Abdominal aortic aneurysms (AAA), Thoracic aneurysms & dissections, Carotid disease & Venous disease and Dialysis access surgery Vascular surgery has seen great advancement in the last two decades with introduction of minimally invasive endovascular techniques and devices. Vascular surgeons are not only required to stay up-to-date with the newest technologies, but also maintain the highest standards in traditional open surgery. I aim to provide comprehensive care to patients suffering from vascular diseases, including open surgical and minimally invasive treatment of peripheral arterial disease, venous disease, carotid disease, hemodialysis access, abdominal aortic aneurysm (AAA) and thoracic aortic aneurysm at Gates Vascular Institute (GVI)/Buffalo General Hospital and Erie County Medical Center (ECMC). I am also involved in the care of trauma patients suffering from vascular injuries at ECMC. I also have research interests in various aspects of vascular diseases including peripheral arterial disease and aortic aneurysm disease. Peripheral arterial disease has been my main focus and I have been involved in various studies investigating novel diagnostic and treatment modalities and their impact on our patients. I believe that technology can help us improve patient care but it should be rigorously tested before it is offered to our patients. Education is an important part of my practice and I train medical students and residents to take care of vascular patients. Some of these trainees will become vascular surgeons, ensuring provision of care to vascular patients in the future.
I was exposed to the field of surgery through my ancestry, as my grandfather and great-grandfather were surgeons. I knew that I wanted to be a surgeon from an early age, and during medical school I always had the surgical field in mind. Helping patients through gastrointestinal cancer treatments and operations has been my passion and focus for almost 40 years. A cancer diagnosis is a tremendous challenge for anyone. Within a single day, it can turn someone's world upside down. Being able to help patients who are in that situation, both as a physician and as a surgeon, is very important to me. Cancer treatment is not only about treating the tumor in the best possible way, but helping the patient and the family cope with the situation and guiding them through it. I began my medical education in Germany and continued my training, research and clinical work in the United States at various well-respected cancer centers, including the University of Pittsburgh, Memorial Sloan-Kettering Cancer Center, City of Hope in California, the Cancer Institute of New Jersey, the Simmons Comprehensive Cancer Center at UT Southwestern in Texas and most recently at Indiana University with the Goshen Center for Cancer Care, before coming to Buffalo, NY. After having worked at a total of five National Cancer Institute-designated comprehensive cancer centers, I consider it a true privilege to now hold a leadership role at a center like Roswell Park that set the model for other cancer centers to follow over a century ago. My clinical interest is in pancreatic, hepatobiliary and upper GI tract cancer. My laboratory-based translational activities focus on experimental combination therapy of pancreatic and gastric cancer. I am a member of 13 scientific organizations, including the American College of Surgeons (ACS), American Association for Cancer Research (AACR), Society of Surgical Oncology (SSO), Americas Hepato-Pancreato-Biliary Association (AHPBA) and Society of University Surgeons (SUS), and have served as committee member or chair and as executive council member on several of these. I am also recognized as an exceptional clinician member of the "Best Doctors in America" and "America's Top Surgeons" databases, and as an outstanding teacher through several academic teaching awards.
