Conditions
Interventions

Inclusion criteria
Inclusion criteria: 1)Patients scheduled to undergo robotic-assisted colorectal resection with D3 lymphadenectomy (including high ligation of the inferior mesenteric artery) for sigmoid colon cancer or rectal cancer (or suspected cases). 2) Patients with a clinical tumor depth of cT1 to cT3. 3) Patients with an ECOG Performance Status of 0 to 2. 4) Patients who are willing to participate in this study, have provided written informed consent, and are 20 years of age or older at the time of consent.

Patients diagnosed with multiple colorectal cancers 4. Patients with a history of colorectal resection 5. Patients diagnosed preoperatively with bowel obstruction, perforation, or penetration 6. Patients diagnosed preoperatively with PDM 7. Patients scheduled for robot-assisted surgery but converted preoperatively to open or laparoscopic surgery 8. Patients whose consent cannot be obtained due to inability to confirm their own will (e.g., dementia, impaired consciousness) 9. Patients with poorly controlled diabetes mellitus 10.
