Abstract:
Objective To analyze Glisson system-related complications after percutaneous thermal ablation of liver cancer and the relationship with tumor location.Methods Data of 2 218 case-times of ultrasound-guided percutaneous thermal ablation in 1 879 patients with liver cancer were retrospectively analyzed.Four types were defined according to the relative position between the tumor and Glisson system:Tumor close to the first branch of the portal vein (type Ⅰ),the second branch of the portal vein (type Ⅱ),the third branch of the portal vein (type Ⅲ) and far away from portal vein (type Ⅳ).Types Ⅰ to Ⅲ were classified as close to Glisson system group,while type Ⅳ was classified as far away from Glisson system group.The Glisson system-related complications (cholesteatoma,bile leakage,serious biliary stricture,cholangiobronchial fistula,arterio-venous fistula and arterial aneurysm) were analyzed.Results Glisson system-related severe complications occurred after 20 case-times (20/2 218,0.90 ％) of thermal ablation.The incidence of Glisson system-related severe complications in close to Glisson system group (1.81 ％ [16/886]) was higher than that in far away from Glisson system group (0.30％ [4/1 332],P＜0.001).The incidence of Glisson system-related severe complications of type Ⅰ,Ⅱ,Ⅲ and Ⅳ was 6.35％ (4/63),3.52％ (5/142),1.03％ (7/681) and0.30％ (4/1 332),respectively (P＜0.001).Glisson system-related mild complications included liver function damage (280 case-times),portal thrombosis (156 case-times) and slight cholangiectasis (82 case-times).The incidences of the three Glisson system-related complications mentioned above decreased from type Ⅰ to Ⅳ.Conclusion Percutaneous thermal ablation is safe in treating patients with tumors close to Glisson system.But the risk of incidence of Glisson system-related severe complications is higher when the tumor is close to the more advanced branch of portal vein.
