Abstract
BackgroundThe study carries the aim to compare the clinical efficacy and economic outcomes of using barbed suture closure versus conventional closure for wounds after posterior long-segment lumbar surgery.MethodsOne hundred and eighty-one patients undertaking posterior long-segment lumbar surgery participated in the prospective randomized controlled trial study to receive either barbed suture wound closure (n = 91) or conventional suture closure (n = 90). Outcome measures included operating room time (ORT), wound closure time, length of incision, length of hospital stay (LOS), 90-day readmission rates, wound complications of dehiscence and infection, and costs.ResultsBarbed suture group was related with significantly lower ORT (P = 0.036), wound closure time (P < 0.001) and average wound closure time (P < 0.001), and significantly lower wound complication rates (dehiscence and infection) (P = 0.031). No significant differences were found when compared with conventional suture group in terms of length of incision (P = 0.086), length of hospital stay (P = 0.174), readmission rates up to 90 days after the surgical procedure (P = 0.232) and costs (P = 0.205).ConclusionThe study suggested the knotless barbed suture technique outperformed the conventional suture in shortening operating room time, wound closure time and average wound closure time, and reducing wound complication rates.
