ABSTRACT
Objective:
Surgical sealant, which is used for the reinforcement of suture lines, has been widely used in lung-resection surgeries with the aim of reducing postoperative morbidity; however, it may exacerbate surgical-site adhesion, creating the risks of restrictive thoracic movement and a difficult entrance for redo operation. We aimed to assess the pleural adhesive effects of 3 frequently used surgical sealants, (1) fibrin glue (fibrin), (2) a composite of polyethylene glycol and human serum albumin (PEG/HSA), and (3) bioabsorbable polyglycolic acid felt (PGA), in an in vivo setting.Methods:
Eighty-one rats were randomly assigned to 3 experimental groups-fibrin, PEG/HSA, and PGA. After intrapleural application of the sealants, the extent and severity of adhesion and inflammation were quantitatively compared among the 3 groups at 2, 4, and 8 weeks.Results:
The scores for both the extent and severity of adhesion were significantly greater in the PGA group than the other 2 groups throughout postoperative period (P < .001 for all). Although both scores in the PES/HSA and fibrin groups were 0 at 2 weeks, the fibrin group showed significantly greater scores than the PES/HSA group thereafter (P < .001 for all). Trends in inflammation scores were similar of those of adhesion scores, favoring the PES/HSA group followed by the fibrin group (P < .001 for all).Conclusions:
Among 3 commonly used sealants, PEA/HSA showed least degree of adhesion/inflammation compared with fibrin and PGA, whereas PGA demonstrated greatest degrees of adhesion/inflammation throughout a postoperative course of 8 weeks in an in vivo model.
