BackgroundThe short-term benefits of laparoscopy for rectal surgery are equivocal. The objective of this study was to determine the clinical and economic impact of an enhanced recovery pathway (ERP) for laparoscopic and open rectal surgery.Materials And MethodsAll patients who underwent elective rectal resection with primary anastomosis between January 2009 and March 2012 at two tertiary-care, university-affiliated institutions were identified. Patients who met inclusion criteria were divided into four groups, according to surgical approach (laparoscopic [lap] or open) and perioperative management (ERP or conventional care [CC]). Length of stay (LOS), postoperative complications, and hospital costs were compared.ResultsA total of 381 patients were included in the analysis (201 open-CC, 34 lap-CC, 38 open-ERP, and 108 lap-ERP). Patients were mostly similar at baseline. ERPs significantly reduced median LOS after both open cases (open-CC 10 days versus open-ERP 7.5 days, P = .003) and laparoscopic cases (lap-CC 5 days versus lap-ERP 4.5 days, P = .046). ERPs also reduced variability in LOS compared with CC. There was no difference in postoperative complications with the use of ERPs (open-CC 51% versus open-ERP 50%, P = .419; lap-CC 32% versus lap-ERP 36%, P = .689). On multivariate analysis, both ERP (-3.6 days [95% confidence interval, CI -6.0 to -1.3]) and laparoscopy (-3.6 days [95% CI -5.9 to -1.0]) were independently associated with decreased LOS. Overall costs were only lower when lap-ERP was compared with open-CC (mean difference -2420 CAN$ [95% CI -5628 to -786]).ConclusionsERPs reduced LOS after rectal resections, and the combination of laparoscopy and ERPs significantly reduced overall costs compared to when neither strategy was used.
