Core Tip

Core tip: Lateral pelvic recurrence after rectal cancer surgery is still a major problem. There have been differences in the treatment of suspicious lateral pelvic lymph nodes between the East and West, treating this as either regional or systemic disease. Lateral pelvic lymph node dissection is a topic of debate in the treatment of these patients. In this study, we evaluate our single-center data, showing our short-term outcomes. Minimally invasive surgery, especially with the robotic platform is shown to be safe and feasible in lateral pelvic lymph node dissection.
