Electives, didactic training, call frequency, procedures

Electives

You will have the opportunity in the second year for a six-week elective rotation in any of the core rotations or additional exposure in gynecologic surgery or basic/translational sciences.

Didactic training

Clinical conferences, small discussion groups, journal clubs, and one-on-one instruction are integral parts of the Complex General Surgical Oncology Fellowship. All fellows are required to attend morbidity and mortality conferences and Grand Rounds. Fellows are also required to attend Monday afternoon Surgical Oncology teaching conference. Protected time is provided.

During each subspecialty rotation, you also attend that subspecialty's weekly schedule of journal clubs, didactic presentations, and conferences dealing with patient management problems, mortality, and morbidity.

You are encouraged to attend national surgical oncology surgery meetings during your fellowship.

Lastly, you will be directly involved in multiple weekly tumor boards including presenting and discussing cases throughout their fellowship. This includes Pancreas Tumor Board, Gastroesophageal Tumor Board, Colorectal Tumor Boards, Cutaneous Malignancies Tumor Boards, Breast Tumor Boards, Endocrine Tumor Boards, and Sarcoma Tumor board.

Call frequency

The fellow call schedule is different for each rotation. Mayo Clinic follows the requirements of the Accreditation Council for Graduate Medical Education (ACGME) work hour restrictions, most likely resulting in two- to three-weekend home-call per six-week rotation block while on a surgical service. You are never on night float and do not provide Acute Care Surgery/Trauma coverage for the emergency department.

Procedures

You will have broad and comprehensive surgical experience with both MIS and open common and complex oncologic operations. This includes hepatic artery infusion pumps (HAIP), intraoperative radiation therapy (IORT), hyperthermic intraperitoneal chemotherapy (HIPEC), pressurized intraperitoneal aerosolized chemotherapy (PIPAC), radical multivisceral resections, and vascular resection and reconstructions, which are often performed independently by many of the Surgical Oncologist/HPB surgeons. Fellows will easily exceed minimum CGSO case volumes during their training. Video: Dr. Travis Grotz explains the steps of a robotic-assisted procedure.

Conferences, research opportunities

Conferences

The fellowship offers active involvement in numerous dedicated multidisciplinary tumor boards, including presenting cases in a multidisciplinary discussion format. Examples of tumors boards that fellows will routinely be involved in depending on the rotation include gastroesophageal, colorectal, sarcoma, pancreas, hepatobiliary, breast, melanoma, and endocrine tumors boards.

There is a twice monthly-run M&M conference in which fellows will present cases they were involved in. You will also participate in educational and journal club conferences relevant to rotating services. There are opportunities to participate in Quarterly Perfusion video conferences as well as didactics based on the SCORE CGSO curriculum.
