Robotic vs Laparoscopic D3-D4 Lymphadenectomy for Colorectal Cancer
Colorectal Cancer
About this trial
This is an interventional treatment trial for Colorectal Cancer focused on measuring Lymphadenectomy, Colorectal cancer, D3-D4
Eligibility Criteria
Inclusion Criteria: Histopathologically proved adenocarcinoma located at upper rectum (above pelvic peritoneal reflection), recto-sigmoid junction, or distal sigmoid colon (generally 10 to 25 cm above anal verge). Only recto-sigmoid cancers above the peritoneal reflection were investigated because the lymphatic drainage of upper rectum and distal sigmoid colon was along the inferior mesenteric artery to the para-aortic area, and therefore the extent of surgical resection and lymph node mapping were standardized. Clinically TNM stage III cancers. Curative robotic or laparoscopic surgery. American Society of Anesthesiology (ASA) class I to III patients. Age between 50 and 75 years. This was because patients >50 years old are generally deemed to be over the reproductive age, and the D3 dissection was considered too aggressive for patients older than 75 years. Patients who are willing to receive minimally invasive surgical procedures to treat their rectosigmoid cancer. Exclusion Criteria: Tumors located at other anatomic positions; Emergency or palliative surgery; Evidence of disseminated disease or adjacent organ invasion; Primary tumor mass ≥8 cm in diameter; Morbidly obese patients (body mass index ≥40 kg/m2); Previous major surgery of lower abdomen.
