Essential Updates 2024-2026: Advances in Colorectal Cancer Surgery

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Surgical innovation in colorectal cancer is evaluated by oncological outcomes, function preservation, and morbidity reduction.
• Recent advancements focus on robotic and minimally invasive techniques for improved patient care.

Purpose of the Study:

• To review major surgical studies on colorectal cancer from 2024-2026.
• To assess the impact of new surgical techniques on oncological outcomes and patient recovery.

Main Methods:

• Structured narrative review of randomized trials and meta-analyses.
• Analysis of studies on robot-assisted surgery, transanal total mesorectal excision, and fluorescence angiography.

Main Results:

• Robot-assisted rectal surgery improved locoregional control and disease-free survival in the REAL trial.
• Transanal total mesorectal excision showed noninferiority but requires careful interpretation.
• Indocyanine green fluorescence angiography reduced leakage rates in specific colectomy types.

Conclusions:

• Surgical benefits are context-specific, depending on case selection, surgeon expertise, and standardization.
• Robot-assisted rectal surgery offers advantages, but oncological equivalence for robotic colectomy and intracorporeal anastomosis requires further study.
