Abstract: Objective To evaluate ultrasound-guided methylene blue dyeing for radical liver segmental resection.Methods Liver segmental resection with uhrasound-guide methylene blue dyeing (UMD-SR) was performed in 16 cases, results were compared with 16 conventional liver segmental resection (CSR) retrospectively.Results All the operations under uhrasound-guided methylene blue dyeing were successfully carried out, among them, reverse dyeing was used in cases with segment Ⅳ, Ⅴ, Ⅷ resection.The blood loss in UMD-SR group was much less than CSR group(t =3.011 ,P =0.009) , at the cost of a longer operation time (t =5.423,P =0.000 07).There was no difference in the mortality and morbidity rates between two groups.Tumor recurrence rate was 6.25％ in UMD-SR group and 18.75％ in CSR group (x2 =0.133,P =0.285).Conclusions Ultrasound-guided methylene blue dyeing liver segmental resection can reduce the blood loss during operation, improve the safety of hepatectomy in case of hepatic carcinoma.
