Departments

Yale’s Department of Surgery is a premier center for adult and pediatric surgical treatment, providing comprehensive care for a full range of conditions and diseases. To ensure that our patients experience shorter hospital stays and less postoperative discomfort, we employ the latest technologies and surgical techniques, and perform minimally invasive surgery whenever possible. Our renowned surgeons and faculty continue to push the frontiers of surgical science through innovative treatment and leading-edge research, with the ability to offer treatment options that can be difficult to find elsewhere. More state-of-the-art surgical suites at Yale New Haven Hospital than in any other hospital in the region Collaboration with the Yale Department of Biomedical Engineering and with industry to develop 3-D bioprinting for the regeneration, repair, and replacement of human tissue and vessels Nationally recognized Center of Excellence and designated training center for transcatheter aortic valve replacement (TAVR) Yale’s Endocrine Neoplasia Laboratory is an internationally renowned multidisciplinary research group in which surgeons work with endocrine geneticists to decipher the molecular genetics of endocrine tumor disease First program in Connecticut to offer three different minimally invasive bariatric surgical techniques: Roux-en-Y gastric bypass, LAP-Band® surgery, and laparoscopic sleeve gastrectomy

Weight management is a complex and multi-faceted challenge that can involve a wide range of health issues, with solutions that are different for every person. The Center for Weight Management, part of Yale New Haven Health (YNHH) and Yale School of Medicine, is a multidisciplinary practice offering a comprehensive range of services for patients needing help to achieve their target weight. The center provides assistance with weight and weight-related health conditions from many different perspectives, with personally tailored solutions based on each patient’s specific needs and goals. Weight management is a lifelong journey, and we are here to help. The center brings together renowned experts in both the medical and surgical treatment of obesity, as well as in such fields as psychology, nutrition, exercise physiology, orthopaedics, endocrinology, cardiology, liver disease, and more. The center doesn’t just focus on weight management, but also on the many health outcomes associated with excess weight, such as diabetes, fatty liver disease, heart disease, joint problems, and cancer. Successful weight management can significantly improve these conditions and reduce the chance of developing them in the first place. In short, the center provides services across the entire continuum of care for weight management, including everything from dietary advice to psychological counseling, medications, endoscopic interventions, and surgery. Having all of those services under one umbrella gives us the unique ability to care for any patient with weight management needs, regardless of size or treatment options. The center also has an alliance with the YNHH Department of Pediatrics, and since obesity tends to run in families, center administrators are planning an intergenerational clinic where the entire family can receive care. Currently, the center is situated at several different locations within the health system; in 2022, all of the components of the center are scheduled to move to a single location at 8 Devine St. in North Haven. Consultations are also available via telehealth. The Center for Weight Management has three physician-directors: John Morton, MD, MPH, medical director of bariatric surgery for the Yale New Haven Health System; Wajahat Mehal, MD, PhD, director of the Yale Weight Loss Program and an expert in obesity medicine and endobariatrics; and Ania Jastreboff, MD, PhD, an adult and pediatric endocrinologist with expertise in obesity medicine and weight management. The center has a fully integrated medical and surgical team. We have approximately 20 physicians, including 12 bariatric surgeons, who together have performed about 10,000 successful surgeries (Dr. Morton alone has performed about 4,000 successful bariatric surgeries). Other members of the team include nurses, dieticians, psychologists, social workers, and an exercise physiologist, as well as the many experts on weight-related health conditions who partner with the center.

At Yale Medicine, our Bariatric and minimally invasive surgery team specializes in surgical care for conditions affecting the digestive tract. Expert surgeons use the latest minimally invasive techniques designed to reduce scarring and minimize discomfort after surgery, providing a smoother and more rapid recovery. We recognize that it’s natural to experience various emotions and concerns before undergoing surgery. That's why our approach focuses on patient education and comprehensive care—we are here to provide clear, detailed answers to all your questions before, during, and after your procedure. About Us Specialized care is offered in the following areas: Abdominal wall reconstruction to treat complex hernias or trauma to the abdomen Laparoscopic surgery to treat severe (Class III) obesity Weight-loss surgery options: Roux-en-Y gastric bypass, in which a small stomach pouch is created to restrict food intake. LAP-Band® surgery, in which a band is placed around the upper part of the stomach to create a small pouch to hold food. The band limits the amount of food that’s consumed by making the patient feel full after eating small amounts. Sleeve gastrectomy, which involves removing about 85% of the stomach. The smaller-sized stomach holds less food, creating a feeling of fullness with significantly less food. All weight-loss surgery options include education and support from nursing, nutrition, and psychological service providers.

We provide comprehensive surgical care for children with inflammatory bowel disease.Our innovative surgeons have extensive experience in the latest surgical technologies and the most delicate surgical situations. We understand that inflammatory bowel disease can present challenges for children. We want to help each child meet and overcome those challenges by exploring how his or her condition affects daily life. We focus on education and making each child’s parent his or her best advocate.

An estimated 80,000 children suffer from inflammatory bowel disease (IBD) in the United States, and the disease is on the rise. We offer comprehensive care to children with IBD—which includes Crohn’s disease and ulcerative colitis—focusing specifically on young patients and their unique needs. We are dedicated to improving the physical and psychological health—and promoting optimal growth—for all children and adolescents with IBD. We are also proud that our remission rates in patients are higher than the national average. At our weekly clinic at Yale New Haven Children’s Hospital, patients can meet with IBD specialists, surgeons, nurses, social workers, and nutritionists who are ready to care for them with the most advanced available technology and medication. If surgery is needed, our skilled surgeons use methods, including laparoscopy, that allow for smaller incisions and quicker recovery. We have a transition plan for patients who are 21 and are ready to move into our IBD program for adults.

Our goal at the Diabetes Center is to give patients the tools necessary to successfully manage the day-to-day challenges of living with diabetes and prevent long-term diabetes complications. We provide comprehensive management and education for adults with type 1 and type 2 diabetes. We focus on lifestyle interventions and use the latest medications and technologies to improve our patients’ health. We also treat patients with: Pre-diabetes and metabolic syndrome Obesity Polycystic ovarian syndrome Lipid or cholesterol abnormalities Our nationally recognized doctors and nurse practitioners work as a team to address our patients’ needs in managing diabetes and other conditions. We understand that living with diabetes presents challenges. We focus on education and making patients their own advocates. Through the most current and state-of-the-art treatments, we will help them better manage their care. Oral Medications There are several classes of oral diabetes medications that we may prescribe if patients have type 2 diabetes. These medications differ in the way they work to reduce blood glucose levels. Frequently, oral medications from different classes are used in combination. Sulfonylureas: These drugs increase the amount of insulin produced by the pancreas. Meglitinides: These drugs rapidly increase the amount of insulin produced by the pancreas. Biguanides: Metformin is the only biguanide on the market. It is thought to work by reducing the production of glucose in the liver. Alpha-Glucosidase Inhibitors: These medications reduce the amount of glucose absorbed in the intestines. Thiazolidinediones: This agent makes the body more sensitive to insulin. Dipeptidyl Peptidase 4 inhibitors (DPP-4 inhibitors): These drugs increase the amount of insulin produced by the pancreas after a meal and reduce the amount of glucose produced by the liver. Injection Therapies There are several classes of injection therapies for diabetes. These treatments are given by an injection under the skin. The most common injection therapy is insulin, which comes in many different formulations that differ in how fast they work and how long they last. Below is a list of the different types of insulins. Technologies and Experimental Treatments Insulin Pumps: Insulin pumps were first pioneered at Yale in the 1970s. An insulin pump is an electronic, pager-sized, battery-powered device that delivers insulin continuously through a small plastic catheter under the skin. Insulin is delivered in different amounts (“basal” or “bolus” levels) during the day and controlled by the patient. While fasting, patients will administer a low level of continuous “basal” insulin to keep their blood glucose in the normal range. Prior to meals, they will determine a “bolus” of insulin based on the amount of carbohydrates in the meal. Continuous Glucose Monitoring systems (CGM): A CGM is a device that measures glucose under the skin (also known as “interstitial” glucose) every five minutes thr

Our program, focused on adult primary care, is known for its excellence and emphasis on prevention and wellness. We efficiently manage potential medical problems as they arise, and collaborate with specialists when needed.

We help children who are overweight or obese improve their health through a variety of strategies, including behavior and lifestyle modification. We understand that many factors can contribute to obesity, including genetics, diet, physical activity level, psychological issues, and adverse family events. Our team includes board-certified pediatric endocrinologists, advanced practice registered nurses, physician assistants, a registered dietitian, a bariatric surgeon, and an endocrinologist who specializes in diabetes and obesity management for adults and children. We work together to tailor treatment to each child and his or her family. Seventeen percent of children ages 2 to 19 in the United States are obese, according to the Centers for Disease Control and Prevention. While there is no cure for obesity, our caregivers work with children to prevent serious health complications that can accompany it, including: Prediabetes and type 2 diabetes Polycystic Ovary Syndrome (PCOS) High cholesterol Fatty liver disease When a child is referred to us—typically from a pediatrician—our first step is to do a full medical examination and check for obesity-related diseases and complications. We offer a traditional approach to weight loss through lifestyle changes, and incorporate the whole family into the process. We refer many children to Yale School of Medicine’s Bright Bodies Program in New Haven, which teaches children and their families about nutrition and encourages them to exercise. If lifestyle and behavioral modifications are not successful, medications are a potential option for children 16 and older. Our last step, if necessary, would be bariatric surgery, also for children 16 and up. There are rigid protocols for the surgery, as well as pre- and post-surgical care. Once patients turn 21, we can seamlessly transition them into an adult program for weight management.
