A critical appraisal of the cost effectiveness of laparoscopic colorectal surgery for oncological and non-oncological resections.

The aim of this study was to critically appraise the cost effectiveness of the laparoscopic colorectal (LCRS) surgery using published randomised, control trials (RCTs). Published RCTs comparing the cost effectiveness of LCRS with conventional open surgery were selected from the search of standard electronic databases and the extracted data were analysed using the statistical software RevMan 5.3. Seven RCTs on 2197 patients reported the cost effectiveness of the LCRS. There was significant heterogeneity (τ  = 161,772.25, χ  = 166.69, df = 6, p = 0.00001, I  = 96%) among included randomised, controlled trials. In the random effects model analysis (MD 320.37, 95% CI -38.21, 678.95, z = 1.75, p < 0.08), the LCRS was costing £320.37 more than open colorectal resection but it failed to reach the statistical significance indicating that LCRS is as much cost effective as the open approach. LCRS is a cost effective intervention and should be offered routinely to all patients requiring colorectal resections provided the resources and expertise are available.
