Background and purpose
Single-port laparoscopy (SPL) is a relatively new technique, used in various procedures. There is limited knowledge about the cost effectiveness and the learning curve of this technique. The primary aim of this study was to compare hospital costs between SPL and conventional laparoscopic resections (CLR) for colorectal cancer; the secondary aim was to identify a learning curve of SPL.
Methods
All elective colorectal cancer SPL and CLR performed in a major teaching hospital between 2011 and 2012 that were registered in the Dutch Surgical Colorectal Audit were included (n = 267). The economic evaluation was conducted from a hospital perspective, and costs were calculated using time-driven activity-based costing methodology up to 90 days after discharge. When looking at SPL only, the introduction year (2011) was compared to the next year (2012).
Results
SPL (n = 78) was associated with lower mortality, lower reintervention rates, and more complications as compared to CLR (n = 189); however, none of these differences were statistically significant. A significant shorter operating time was seen in the SPL. Total costs were higher for SPL group as compared to CLR; however, this difference was not statistically significant. For the SPL group, most clinical outcomes improved between 2011 and 2012; moreover, total hospital costs for SPL in 2012 became comparable to CLR.
Conclusion
No significant differences in financial outcomes between SPL and CLR were identified. After the introduction period, SPL showed similar results as compared to CLR. Conclusions are based on a small single-port group and the conclusions of this manuscript should be an impetus for further research.
