[Scientific evidence for laparoscopic rectal cancer surgery]

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Colorectal Surgery

Background:

• Innovative surgical techniques aim to reduce injury and improve oncological outcomes in colorectal surgery.
• High-level clinical studies are essential to validate new operative techniques.

Purpose of the Study:

• To evaluate the safety and oncological quality of laparoscopic rectal cancer surgery.
• To determine if results from laparoscopic colon cancer resection are applicable to rectal cancer.

Main Methods:

• Prospective randomized studies, including the COLOR-II trial.
• Comparison of laparoscopic resection versus open resection for rectal cancer.

Main Results:

• Laparoscopic rectal resection is not inferior to open resection in short-term outcomes.
• Laparoscopic surgery demonstrated advantages in blood loss, recovery, pain management, and hospital stay.
• Improved lateral safety margins were observed in laparoscopic procedures for distal rectal cancer.

Conclusions:

• Laparoscopic total mesorectal excision (TME) shows clinically significant short-term advantages for rectal cancer patients.
• Laparoscopic rectal cancer resection is a strong candidate for becoming the future gold standard in treatment.
