Objectives of the Program:

The main objective of the Mount Sinai Endocrine Surgery Fellowship program is to train the next generation of endocrine surgeons. Fellows receive broad exposure to all aspects of endocrine surgery with an emphasis on the AAES core curriculum for endocrine surgery, minimal access techniques and head & neck cancer surgery.

Highlights of the Fellowship:

In Sept 2013, the Mount Sinai Medical Center acquired 5 NYC hospitals to become the Mount Sinai Health System, the largest healthcare organization in New York City with 37,000 employees. To capitalize on the immense educational opportunity, the Mount Sinai endocrine surgery fellow is able to perform surgery and see patients at several sites in Manhattan and Queens. Four fellowship-trained endocrine surgery attendings continually collaborate through health system-wide endocrine tumor boards, research and quality initiatives. The fellow will be exposed to the following:

1. Minimally invasive thyroid and parathyroid procedures (local anesthesia, video-endoscopic, trans-oral techniques, nerve monitoring) as well as conventional approaches

2. Laparoscopic/robotic adrenalectomy (transabdominal and retroperitoneal) as well as open adrenalectomy for ACC

3. Hepatic and pancreas endocrine surgical oncology (RFA/resection neuroendocrine hepatic metastases, carcinoid, islet cell tumors)

4. Office-based procedures (cervical ultrasonography, ultrasound guided fine needle aspiration, fiberoptic laryngoscopy)

5. Head and neck oncology (neck dissection, parotid, melanoma, squamous cell cancer)

6. Multidisciplinary Endocrine Neoplasia Center office hours and conferences [which includes the Thyroid and Parathyroid Center (staffed by endocrine surgery, endocrinology, cytopathology, nuclear medicine and medical oncology) and The Adrenal Center (staffed by endocrinology, endocrine surgery, cardiology, medical oncology and other ancillary specialists).

The Fellow has one protected academic/research day per week, participates in several clinical research projects during the year and is expected to present at a national meeting, generally AAES, IAES, SAGES, ACS. To facilitate the production of academic videos, the fellow is provided with access to professional quality video recording and editing equipment. The fellow is expected to assist in writing review articles and book chapters. The fellow presents Grand Rounds to the Department of Surgery and/or at other venues and plays an active role in the education of Mount Sinai residents and medical students.
