Recent advances in technology and techniques have significantly improved outcomes for patients with rectal cancer. This event will spotlight two of the most groundbreaking innovations in the field. Our expert panel will present data on lateral pelvic node dissection and the use of indocyanine green (ICG), along with the integration of these methods. The program will emphasize the cost-effective laparoscopic approach to lateral pelvic node dissection and demonstrate how ICG enhances the safety and precision of pelvic dissection. Internationally renowned faculty will share valuable insights, including data, surgical videos, and practical tips for adopting these laparoscopic techniques globally.

PROGRAM 1. Intraoperative Diagnosis - Dr. Jurrian Tuynman Since anastomotic leaks pose a real danger to patient outcomes, surgeons should always keep this problem in mind. To prevent them as much as possible, patient optimization must be achieved. The aspects and characteristics associated with anastomotic leakage should also be known so as to make good decisions regarding the procedure. However, sometimes anastomotic leaks cannot be prevented, so action must be taken. Recommendations supported by images are given. 2. Laparoscopy (second laparoscopic approach) to diagnose and treat anastomotic leak. - Dr. Nicolas Rotholtz Reoperative laparoscopic surgery is performed on patients who have already been operated through a laparoscopic procedure, but complications have required a further operation. The scientific literature on the techniques used in complications is discussed. Videos and images of the techniques, and technical documentation are also explained. 3. Early diagnosis and complementary tests according to anastomotic leak risk factors - Dr. Lucia Oliveira Given the gravity of anastomotic leaks and how important their treatment is, it is crucial to be aware of the risk factors and the techniques to prevent them. Despite this, anastomotic leaks can occur, so it is really important to detect them early. In this video, different paths are considered depending on the patient’s characteristics. The studies and papers that show the relationship between risks and symptoms in anastomosis are also discussed.
