Laparoscopic Gallbladder Removal Cholecystectomy near Bronxville, NY

Biography: Dr. Emond is the Vice Chairman of Surgery at Columbia University. He has over 30 years of experience performing liver transplantation and complex liver and biliary surgery in children and adults, including the first living donor liver transplantation (LDLT) in the United States. Dr. Emond has published extensively in this field and was the co-chair of the NIH A2ALL program for 13 years. In collaboration with the department of Medicine at Columbia, Dr. Emond recruited the leadership of the Columbia Center for Translational immunology that created the foundation for translational and clinical research in transplantation tolerance. This will lead the way to inducing transplant tolerance in liver patients with the mixed chimerism strategy. As Director of Transplantation at the Columbia University Medical Center Dr. Emond's activities foster clinical excellence and research across all 11 of the solid organ transplant programs at the Medical Center. In recognition of his national and international leadership in transplantation, Dr. Emond is the past president of the American Society of Transplant Surgeons, the pre-eminent association of a transplant surgery. Contribution to Science Living donor liver transplantation Dr. Emond has spent a substantial portion of his career developing living donor liver transplantation and studying the safety of the procedure in both the donor and recipient. He participated in the first living donor liver transplant in the United States and focused on refining the techniques of performing living donor liver transplants and split liver transplants. He was the national co-chair of the NIH-sponsored Adult-to-Adult Living Donor Liver Transplantation (A2ALL) consortium from 2002 to 2015 to study the safety and outcomes of living donor liver transplants. Hepatic resection/ischemia Dr. Emond developed techniques for surgical resection of liver tumors and studied the effect of ischemia during resection on postoperative liver function. These studies include the outcomes of the extent of hepatectomy, the biochemical response to major hepatectomy and ischemia-reperfusion injury of the liver in rodent models. He has studied the clinical safety of inducing total vascular exclusion to provide a bloodless field during the liver transection. This has applications in both liver cancer and living donor hepatectomies. Hepatocellular carcinoma treatment Dr. Emond has studied many aspects of managing patients with hepatocellular carcinoma. These studies have included characterizing the risk factors for recurrence of disease following transplantation due to comorbidities and tumor characteristics. The research team has also studied the optimal method of preventing tumor growth in patients with HCC on the liver transplant wait list in addition to optimal strategies of liver allocation to optimize outcomes following liver transplantation. These studies have contributed to proposed changes in UNOS exception point allocation for liver transplant candidates with HCC. Pediatric liver transplantation Dr. Emond helped develop the field of pediatric liver transplantation. Contributions to this field include: the use of living donors for pediatric patients; use of auxiliary liver transplants for metabolic diseases; use of partial liver grafts for pediatric patients; and technical modifications that improved outcomes for this patient population.

Biography: Naomi Berezin is an Assistant Professor of Surgery and Critical Care at Columbia University Irving Medical Center. She specializes in both emergency and elective general surgery to treat such conditions as gallbladder disease, hernias, diverticulitis, and bowel obstruction, as well as the care of critically ill surgical patients. Dr Berezin's two passions are patient care and medical education. "I liked working with my hands as a child," says Dr. Berezin, who continued that interest in college at New York University where she studied English literature and music, before going on to complete the Post-Baccalaureate Premedical Program at Columbia University. "Working with my hands is what drew me to surgery." Dr. Berezin talks to patients about their diagnosis and treatment using language they can grasp. "I like to draw pictures for my patients so they can understand what I am talking about," she says. "I'm a visual learner and I've found that doing this enables patients to participate in their care. People ask really insightful questions when they are included in shared decision making." Dr Berezin teaches medical students and residents and is involved in courses on palliative care and surgical board preparation. Dr. Berezin is a member of a number of professional societies including the Eastern Association for the Surgery of Trauma, American Association for the Surgery of Trauma, Society of Critical Care Medicine, and American College of Surgeons. She is dually board-certified in both General Surgery and Surgical Critical Care. After graduating from Sackler School of Medicine, Dr Berezin went on to complete her general surgery residency training at Albert Einstein College of Medicine/Montefiore Medical Center. She then completed a trauma and surgical critical care fellowship at Cedars-Sinai Medical Center before embarking on her career at Yale School of Medicine.

Biography: Dr. William Middlesworth joined the medical staff of Morgan Stanley Children's Hospital of NewYork-Presbyterian/Columbia (MSCHONY), Division of Pediatric Surgery in 1997. He currently serves as director of the Pediatric ECMO Program, and Residency Program Director of the Pediatric Surgical Fellowship. Dr. Middlesworth has founded and leads the Pediatric Thyroid Center and the REACH (Researching Esophageal Atresia for Children's Health) Clinic. A graduate of Dartmouth College, Dr. Middlesworth spent two years in the Genetics Department at the Boston Children's Hospital on work leading to the identification and characterization of the dystrophin gene, important in the pathophysiology of muscular dystrophy. He went on to medical school at Rutgers University, and completed his general surgery training at the University of Maryland Medical System. During residency he spent a year as a surgical research fellow at the Royal Children's Hospital in Melbourne, Australia. His pediatric surgery fellowship was completed at MSCHONY. In addition to the responsibilities listed above, Dr. Middlesworth serves on numerous hospital and university committees focused on Quality and Patient Safety, and is the Quality Chair for Columbia Department of Surgery. He is the Surgeon Champion at the Columbia campus for the National Surgical Quality Improvement Project (NSQIP) of the American College of Surgeons. He chairs a multi-institution collaborative to reduce harm and enhance safety in the peri-operative setting that is sponsored by MCIC Vermont, the member-owned malpractice insurance carrier for Columbia, Cornell, New York Presbyterian Hospital, Johns Hopkins Medicine, University of Rochester Medicine and Yale. Dr. Middlesworth is a fellow of the American College of Surgeons, and the American Academy of Pediatrics. He is a member of numerous professional organizations dedicated to advancing the surgical care of infants and children, including the American Pediatric Surgical Association (APSA), the Eastern Association for the Surgery of Trauma(EAST) and the Extra-corporeal Life Support Organization(ELSO), among others. Dr. Middlesworth has been selected as a Best Doctor in New York Magazine, and a Castle Connolly Top Doctor. He has received recognition for excellence in teaching, and authored numerous papers in important journals including the Journal of Pediatric Surgery, the Journal of Pediatric Hematology and Oncology and Pediatric Critical Care Medicine.
