Comparison of perioperative blood loss of three different posterior nonfusion decompression operations for single-segment lumbar disc herniation

In terms of perioperative blood loss, the PEID group was more minimally invasive than the UBE and OPD groups. Compared with OPD group, UBE group was less invasive, but did not significantly reduce the amount of hidden blood loss after surgery. In terms of operation time, UBE group had the longest operation time and OPD group had the shortest operation time. In terms of hospitalization days, OPD group had the longest hospital stay. In terms of total hospitalization cost, UBE group had the highest total hospitalization cost and PEID group had the lowest total hospitalization cost. The clinician should choose the appropriate surgical plan according to the actual situation of the patient to ensure the efficacy and safety of the operation.
