Reducing Complications in Esophagus Surgery

Esophageal cancer remains one of the most prevalent cancers globally and a leading cause of cancer-related mortality. Among the various treatments available, three-field lymphadenectomy has recently gained significant attention. Originating in Japan in the 1980s and now utilized in several other countries, it continues to be a topic of active discussion, especially in the context of contemporary neoadjuvant treatments. This upcoming webinar will bridge Japanese and European perspectives on this critical topic. We will explore best practices and review evidence on reducing complications, providing valuable insights for surgeons worldwide.

Improving Oncological Outcomes with Precise Surgery

In the ever-evolving landscape of medical science, precision surgery has emerged as a game-changer, offering new hope for patients. Japan, with its pioneering advances in medical technology and expertise, is at the forefront of this transformative approach. Precision surgery is a paradigm shift in the way we approach cancer treatment. By employing state-of-the-art techniques and cutting-edge technology, surgeons can now target tumors with unparalleled accuracy. As we continue to reimagine how we heal, the integration of precise surgery techniques offers newfound optimism for patients.

CME with D3 dissection for colon cancer

This session will cover a Complete Mesocolic Excision (CME) with D3 dissection for colon cancer. This is a modern type of combined surgical procedure. Currently, both European and Japanese doctors are doing an increasing number of these procedures with lymph node dissection and Complete Mesocolic Excision. First, he goes over statistics regarding how many cases are performed each year in Japan, then moves on to provide a brief overview of the history of D3 dissection surgery in Japan.    Dr. Tsuyoshi Konisihi affirms that many studies with oncologic outcomes for colon cancer have not improved as much as the outcomes for rectal cancer. When it comes to the learning curve of CME procedures in rectal cancer, we should point out that many surgeons are performing this type of surgery as ‘minimally invasive surgery’ and there’s good transmission of knowledge on this topic. Nevertheless, while there’s no exact information about the learning curve, it is the doctor’s opinion that a laparoscopic procedure needs at least 10 cases to feel comfortable.  Bearing in mind that we are coping with a treatable metastasis, it is necessary to perform CME with D3 dissection in metastatic cancer. Also, the doctor tells us that this kind of surgery was treated as being very specific in the past but over the years these operations have become more common. In conclusion, the prevention of colorectal cancers is very important for the maintenance of a healthy population. 

Lateral Lymph node dissection for rectal cancer

The main issue discussed in this talk is lateral lymph node dissection for rectal cancer. There is not a single main step across Japan, but rather there are several approaches to lower rectal cancer.  Dr. Yusuke Kinugasa answers questions from the audience about different approaches to attacking colorectal cancer in Japan based on his experience. When it comes to lymph node dissection, robotic surgery is a good option.  Dr. Kinugasa answers all questions related to risks, discusses which method has improved the most in recent years, and the preoperative steps to be taken before surgery.  He also discusses complications and how they can be treated, and whether the patient must follow a strict postoperative procedure.  During the talk, the audience interacts with Dr. Kinugasa, asking questions about his specialty.
