Lower need for allogeneic blood transfusion after robotic low anterior resection compared with open low anterior resection: a propensity score-matched analysis.

Robotic low anterior resection (R-LAR) for rectal cancer may decrease estimated blood loss compared with open low anterior resection (O-LAR). The aim of this study was to compare estimated blood loss and blood transfusion within 30 days after O-LAR and R-LAR. This was a retrospective matched cohort study based on prospectively registered data from Västmanland Hospital, Sweden.
