Objectives of the Program:

Endocrine surgery has a longstanding, rich tradition in the Department of Surgery at UT Southwestern Medical Center. Dr. William H. Snyder, III, started the endocrine surgery practice at UTSW in 1971, building a legacy of high-quality care until his death in 2010. Twenty years later, the practice has its own division and employs 7 fellowship-trained endocrine surgeons in North Texas, representing fellowship training from the University of Wisconsin, University of Michigan, Mayo Clinic, UCSF, MD Anderson, UCLA, Cleveland Clinic and Johns Hopkins.

The objective of the William H. Snyder Endocrine Surgery Fellowship is to train future leaders in the field of endocrine surgery who can confidently manage the breadth and depth of simple and complex diseases of the thyroid, parathyroid, and adrenal glands. These principles will be taught in a multidisciplinary university setting.

Highlights of the Fellowship:

The Division of Endocrine Surgery employs 7 endocrine surgeons (Dr. Shelby Holt, Dr. Alan Dackiw, Dr. Sarah Oltmann, Dr. Ana Islam, Dr. Ankeeta Mehta, Dr. Vivek Sant and Dr. Meghan Parmer)) and performs over 1,000 endocrine operations annually and growing. The fellows will be exposed to the full scope of endocrine surgical diseases across our 3 clinical sites, which provide exposure to complex referrals and re-operations (William P. Clements Jr. University Hospital), county hospital population (Parkland Memorial Hospital), and community-based practice (UT Southwestern Frisco). The fellows will become well-versed in work-up and management of endocrine disease in weekly clinics with each of the Faculty and will have the opportunity to become proficient in performing head and neck ultrasounds, fine-needle aspiration biopsies, and flexible laryngoscopies. We anticipate fellows to complete between 350-400 routine and complex cases with extensive exposure in thyroidectomy for both benign and malignant disease (~200), central and lateral neck dissections (~30), parathyroidectomy (~150), and laparoscopic/ robotic/ open adrenalectomy (~35), with a substantial number of re-operative cases. Additionally, the fellow will develop expertise in minimally-invasive approaches, use of intra-operative PTH, and intra-operative laryngeal nerve monitoring.

The endocrine surgery division is an excellent example of a multidisciplinary practice. The group collaborates with dedicated specialists in medical endocrinology, mineral metabolism, radiology and nuclear imaging, and endocrine pathology, with whom the fellow will rotate, to care for a breadth of disorders of the thyroid, parathyroid, adrenal, and neuroendocrine pancreas. An example of this collaborative effort is the Multidisciplinary Endocrine Tumor Clinic at Parkland, in which the fellow is expected to participate.

Average Thyroid Case Volume: 200
Average Parathyroid Case Volume: 150
Average Adrenal Case Volume: 40

Neuroendocrine Tumors (NET)

Number of evaluation and management of NET (enteric and pancreatic only) cases per year: 5
Number of operative NET (enteric and pancreatic only) cases per year: 2

If the fellow desires, there is an internal opportunity to engage in a more robust NET experience by participating on the Hepatobiliary service.

International Medical Graduates:

Our program is not able to accept international applicants at this time.

Special Considerations:

The candidate must be eligible for and obtain a Texas medical license and DEA license prior to beginning the fellowship. The fellow will be required to apply for privileges at the Clements University Hospital and Parkland Memorial Hospital, and Texas Health Resources Frisco.
