Optimal surgical techniques for curative resection of the rectal cancer

The aim of rectal cancer surgery is to achieve a curative resection by completely removing the rectum involved with cancer surrounding the mesorectum, obtaining a safe adequate resection margin, and preserving important structures crucial for the patient's quality of life. Optimal dissection along the avascular embryological fusion line and among deep invisible structures is essential. Whereas a minimally invasive surgical approach allows for better visibility of deep pelvic structures compared with the open surgery period, the sequence of dissection and anatomical knowledge about pelvic fascia and relevant nerve structures are crucial for safe pelvic dissection in terms of oncologic and functional outcomes. In this review, we represent practical technical tips based on personal experience and previous studies to achieve the mentioned goals.
