First, the NOSES technique is minimally invasive, reducing the incidence of postoperative complications such as wound infection and fat liquefaction.

Additionally, NOSES provides all of the advantages of minimally invasive surgery and enables patients to recover quickly, helping patients return to their normal lives faster. This approach aligns with the concept of patient-centered care and significantly improves patient quality of life. The positive results noted at both short- and long-term postoperative follow-up indicate that NOSES is a valuable option in cancer care. Despite its many benefits, NOSES has also been challenged by bacteriology, oncology, and ethics.
