Summary
Redo laparoscopic colorectal resection (Re-LCRR) is safe and effective for colorectal cancer, showing good short-term outcomes. However, fewer lymph nodes were harvested compared to primary resections, necessitating further study on long-term prognosis.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Redo laparoscopic colorectal resection (Re-LCRR) is infrequently reported.
- Evaluating the safety and short-term outcomes of Re-LCRR is crucial for patient management.
Purpose of the Study:
- To assess the safety and short-term outcomes of Re-LCRR for colorectal cancer.
- To compare Re-LCRR with primary laparoscopic colorectal resection (LCRR) using a matched case-control analysis.
Main Methods:
- Retrospective, monocentric study of patients undergoing Re-LCRR for colorectal cancer (2011-2019).
- A 2:1 matched sample of patients undergoing primary LCRR was selected for comparison.
- Matching criteria included age, sex, BMI, surgical procedure, and clinical stage.
Main Results:
- Twenty-nine Re-LCRR cases (RCRR group) were compared to 58 primary LCRR cases (PCRR group).
- No significant differences were observed in operative time, blood loss, conversion rates, comorbidity, or hospital stay.
- While radical margin rates were similar, the RCRR group had significantly fewer harvested lymph nodes (p=0.015).
Conclusions:
- Re-LCRR demonstrates favorable short-term safety and outcomes for colorectal cancer.
- A significant reduction in harvested lymph nodes is noted in Re-LCRR compared to primary LCRR.
- Further research is required to determine the long-term oncological prognosis of Re-LCRR.
