Summary
Minimally invasive surgery for rectal cancer showed no significant difference in postoperative C-reactive protein (CRP) levels between laparoscopic (LAP) and robotic (ROBOT) approaches. While robotic surgery showed numerically lower CRP levels on postoperative days 2-4, further research is needed to confirm clinical relevance.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Inflammation Biomarkers
Background:
- Minimally invasive surgery (MIS) is increasingly used for rectal cancer treatment.
- Assessing postoperative inflammatory response is crucial for patient recovery.
- C-reactive protein (CRP) is a key biomarker for inflammation.
Purpose of the Study:
- To compare postoperative inflammatory response, measured by CRP levels, between laparoscopic anterior resection (AR) and robotic-assisted AR for rectal cancer.
- To evaluate the efficacy of different MIS techniques in managing the inflammatory cascade post-surgery.
Main Methods:
- A retrospective study included 123 patients undergoing AR for rectal cancer via MIS (laparoscopic or robotic) between 2011-2021.
- CRP levels were measured preoperatively and on postoperative days 1-5.
- Data were collected from the Swedish Colorectal Cancer registry and patient charts.
Main Results:
- No statistically significant difference in CRP levels was observed between laparoscopic (LAP) and robotic (ROBOT) surgery.
- Numerically lower CRP values were noted in the ROBOT group on postoperative days 2-4.
- Complication rates and hospital stay duration were similar between LAP and ROBOT groups.
Conclusions:
- Postoperative inflammatory response, as indicated by CRP, does not differ significantly between LAP and ROBOT for rectal cancer AR.
- The numerical trend of lower CRP in the ROBOT group warrants further investigation into its clinical significance.
- Both techniques appear comparable in managing postoperative inflammation in this cohort.
