This video begins with a brief introduction of natural orifice specimen extraction for middle colorectal cancer with the indications and contraindications are clearly defined. Following segment shows an animation summarizing key technical points and operational skills. In the end, the main procedures of laparoscopic middle rectal cancer resection with transanal specimen extraction (NOSES II) are presented. It is helpful for gastrointestinal cancer surgeons and general surgeons to have a better understanding on technical difficulties and key issues of laparoscopic middle rectal resection with transanal specimen extraction.
This video introduces natural orifice specimen extraction for middle colorectal cancer with the indications and contraindications are clearly defined.

With the great advances of minimally invasive surgery over the last decade, various techniques spring up. As one of the representatives, Natural Orifice Specimen Extraction Surgery, also known as NOSES, has attracted widespread attention in recent years. A series of video about NOSES in colorectal surgery has been made with the purpose of comprehensively understanding this technique in treatment of colorectal cancer.
NOSES is created and systematically classified by Professor Xishan Wang. He serves as the director of Colorectal Surgery Department in National Cancer Center, Cancer Hospital Chinese Academy of Medical Sciences and Peking Union Medical College, the chairman of Chinese Medical Doctor Association, Colorectal Cancer Committee, the chairman of Chinese Anti-cancer Association, Colorectal Cancer Committee, the Chairman of International NOSES Alliance and Chinese NOSES Alliance, et cetera.
NOSES is defined as the surgical procedures, including specimen resection or reconstruction, are performed intracorporeally by laparoscopic, robotic device or flexible endoscope followed by specimen extraction through a natural orifice, anus, vagina, or mouth. According to the roots of specimen extraction, NOSES in colorectal cancer is divided into transanal specimen extraction and transvaginal specimen extraction. According to the tumor locations, 10 different NOSES techniques are proposed.
In terms of rectal cancer, five approaches specific for the upper, middle, and lower rectal cancer are included. For the lower rectal cancer, we further propose five methods, and we will show them in detail in other videos of our CRC-NOSES series. Colon cancer resection also includes eight approaches, mainly for the left colon, right colon, and the total colon. In this video, we will demonstrate laparoscopic middle rectal cancer resection with transanal specimen extraction. We name it as the CRC-NOSES II.
