Abstract:
Objective To investigate the clinical value of lasting methylene blue staining in precise hepatectomy.Methods The clinical data of 21 patients with liver cancer who received precise hepatectomy after methylene blue staining at General Hospital of PLA from February to August in 2009 were retrospectively analyzed.After the hepatic pedicle Was dissected,methylene blue WaS injected into the portal vein,and then the hepatic pedicle was ligated.Parenchymal division is initiated along the line of devascularization demarcated on Glisson capsule.Results The success rate of methylene blue staining Was 100%.Methylene blue retained in the parenchyma for(80±23)minutes.Right hepatectomy was performed on 2 patients,left hepatectomy on 1,right posterior lobectomy on 2,right anterior lobectomy on 3,left lateral lobectomy on 1,segmentectomy of segment Ⅷon 2,segmentectomy of segment Ⅶ on 3,segmentectomy of segment Ⅵ on 1,segmentectomy of segment Ⅳ on 2 and combined segmentectomy on 4.The mean volume of blood loss,incidence of postoperative complications and postoperative hospital stay were(236±6)ml,14%(3/21)and(12±3)days.Conclusions Ligation of hepatic pedicle after methylene blue injection has the advantages of high success rate and lasting staining of parenchyma of liver.Especially,this staining method contributes to improve the precision of hepatectomy by guiding the segment selection during parenchyma transection.
