The University at Buffalo Advanced Minimally Invasive Surgery Program provides a structured educational experience necessary to achieve expertise in minimally invasive surgery techniques relating to advanced GI surgery while also providing exposure to laparoscopic and bariatric procedures.

Educational Curriculum

Clinical experience is gained through progressive responsibility and increased autonomy over the course of the one-year fellowship. The fellow will gain exposure and experience to upper GI, bariatric, colorectal, hernia, solid organ, urologic, and thoracic procedures. They will learn techniques in robotic assisted laparoscopic and thoracoscopic operations. The fellow will also be exposed to complex open gastrointestinal and hepatopancreaticobiliary procedures.
