BACKGROUND: Giant @entity409 >20  cm may cause severe complications; therefore, operative treatment can be highly difficult and risky. No studies have been performed to determine the characteristics of this subgroup. METHODS: A retrospective study was performed on 141 @entity1 who underwent operative treatment for @entity409 . The @entity1 were divided into an extremely @entity2695 group (>20  cm, 36 cases) and a @entity2695 group (>10  cm but <20  cm, 105 cases). A comparison was then made between the groups. For @entity1 in the extremely @entity2695 group, further comparison was also made between liver resection and enucleation. RESULTS: Compared with the @entity2695 group, @entity1 in the extremely @entity2695 group had greater rates of @entity1431 (P < .001), @entity417 (P < .001), @entity882 (P < .001), @entity3043 (P < .001), prolonged prothrombin time (P < .001), and @entity16970 (P = .001). @entity1 in the extremely @entity2695 group also had greater rates of compression of the hepatic vein (P < .001), inferior vena cava (P < .001), and porta hepatis (P < .001). The extremely @entity2695 group had more @entity190 (P < .001) and autologous transfusion (P < .001), greater rates of blood transfusion (P < .001), and greater postoperative stays (P < .001). Morbidity was greater in the extremely @entity2695 group; however, this difference was not statistically significant (P = .076). For @entity1 in the extremely @entity2695 group, no differences were detected regarding autologous transfusion, blood transfusion, or morbidity between enucleation and liver resection. CONCLUSION: @entity2695 may cause @entity1503 systems. Operative treatment may be difficult and risky but can be completed safely.
