R0 Resection Rates in Minimally Invasive Versus Open Pelvic Exenteration for Colorectal Malignancies: A Systematic...

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Minimally Invasive Procedures

Background:

• Pelvic exenteration is a key treatment for advanced colorectal cancer.
• Achieving R0 resection is crucial for patient outcomes.
• Minimally invasive surgery (MIS) offers potential benefits but requires further evaluation.

Purpose of the Study:

• To compare the oncological and clinical outcomes of MIS versus open pelvic exenteration for colorectal cancer.
• To evaluate the feasibility and safety of MIS in this complex procedure.

Main Methods:

• Systematic review and meta-analysis of retrospective studies.
• Included studies compared MIS (laparoscopic/robotic) with open pelvic exenteration.
• Primary outcome: R0 resection rate; secondary outcomes: operative, postoperative, and oncological results.

Main Results:

• No significant difference in R0 resection rates between MIS and open approaches (p=0.41).
• MIS demonstrated significantly reduced intraoperative blood loss and shorter hospital stay.
• MIS was associated with improved 3-year overall and disease-free survival rates.

Conclusions:

• Minimally invasive surgery (MIS) is a viable option for pelvic exenteration in colorectal cancer, yielding comparable R0 resection rates to open surgery.
• MIS offers advantages in terms of reduced blood loss, shorter recovery, and enhanced survival.
• Further high-quality, prospective studies are necessary to confirm these findings and mitigate selection bias.
