MIS Fellowship

The Stanford Minimally Invasive Surgery/Bariatrics/Foregut Fellowship provides a one year fellowship offering a wide range of surgical exposure with a unique bariatric surgery experience at an American College of Surgeons certified Bariatric Center of Excellence.

Along with foregut/solid organ/and endoscopic training, the Stanford MIS fellowship has extensive bariatric surgery exposure including laparoscopic gastric bypass, sleeve gastrectomy, gastric banding, and adolescent bariatric surgery. In addition to traditional laparoscopic experience, we also offer natural orifice surgery (Apollo/Esophyx) and single incision surgery (cholecystectomy, splenectomy).  

Beyond this strong surgical experience, the successful applicant will also be given clinical instructor status at one of the most prestigious universities in the country with all the requisite resources including a teaching portfolio and access to an American College of Surgeons Education Institute.

Our former fellows have had success during fellowship winning best fellow presentations at both SAGES and ASMBS as well as placement both in community and academic settings. We are pleased to offer this one-year MIS fellowship at the Stanford Department of Surgery.
