E174 - Bridging East and West on colorectal cancer, with Tsuyoshi Konishi

Tsuyoshi Konishi Dr. Tsuyoshi Konishi is an associate professor of Colon and Rectal Surgery at the University of Texas M.D. Anderson Cancer Center, in Houston, USA. We again got a chance to hear several of his talks at the COLOSOS conference in Toronto in Oct 2024. Dr. Konishi is really helping to bridge the gap between “Eastern” and “Western” approaches to colorectal cancer. In this episode, Dr. Konishi really broke down the sometimes nebulous concept of complete mesocolic excision in right sided colon cancers. We’d really encourage you to head over to our YouTube channel www.youtube.com/@coldsteelsurgery to check out the accompanying video and slides. One of the really enjoyable parts of this conversation was discussing some of the differences between Japanese and North American training – there’s lots we can learn! Maybe we should incorporate the Japanese system of having everyone upload their operative video prior to board certification?? What do you think?
