Robotic laparoscopic rectal resection (RR) significantly reduces conversion rates compared to standard laparoscopic rectal resection (LR). While RR shows fewer conversions, both methods have similar outcomes, but conversions increase postoperative complications.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Conversion from laparoscopic to open surgery negatively impacts postoperative outcomes.
- Laparoscopic rectal resection (LR) and robotic laparoscopic rectal resection (RR) are surgical options for rectal cancer.
Purpose of the Study:
- To compare conversion rates and postoperative outcomes between standard laparoscopic rectal resection (LR) and robotic laparoscopic rectal resection (RR).
Main Methods:
- A national 5-year cohort study of elective major laparoscopic resections for rectal cancer.
- Data analyzed from the Norwegian Registry for Gastrointestinal Surgery and Norwegian Colorectal Cancer Registry.
- Propensity score matching and logistic regression analyses were used to compare outcomes and identify predictors of conversion.
Main Results:
- Robotic laparoscopic rectal resection (RR) had a significantly lower conversion rate (2.1%) compared to standard laparoscopic rectal resection (LR) (9.6%).
- RR was associated with a reduced risk of conversion (aOR 0.22).
- Conversions were linked to higher rates of major complications, reoperations, and longer hospital stays.
Conclusions:
- Robotic assisted rectal resections demonstrate a lower conversion rate than conventional laparoscopy.
- Conversions during rectal resection are associated with increased postoperative complications.
