Safety and efficacy of ligasure vessel sealing system for thyroidectomy: a Meta analysis / 中华内分泌外科杂志

ABSTRACT

Objective To evaluate the safety and efficacy of ligasure vessel sealing system (LVSS) and conventional ligation haemostasis in thyroidectomy.Methods Pubmed,EMBASE,Medline,and CNKI were performed to search for randomized controlled trial.Literature selection and data collection were completed by 2 researchers independently.The assessment of methodological quality was conducted with Cochrane Handbook 5.1.The Review Manager software 5.2 was used for Meta analysis.Results A total of 11 studies (934 patients) were involved.Meta-analysis indicated that the operation time was shorter in LVSS group [WMD=-12.47,95％ CI (-18.33,-6.61),P＜0.0001].No significant difference was found in intra-operative blood loss,incidence of hypocalcaemia,recurrent laryngeal nerve (RLN) injury,or hospitalization time between the 2 groups (P＞0.05).Conclusion LVSS can reduce the operation time without increasing intra-operative blood loss,incidence of hypocalcemia,RLN injury,or hospitalization time,which is a safe and effective haemostasis method.
