[Absrt act] Obj ective To summarize the clinical experience with isolated complete resection of he-patic caudate lobe in 14 patients. Mte hods The clinical data of 14patients with isolated complete resection of hepatic caudate lobe carried out in our hospital from December 2007 to March 2015 were retrospectively analyzed .During the operation , selective hepatic vascular occlusion slings , and supra-and infra-hepatic in-ferior vena cava slings were placed after full mobilization of the liver .Isolated complete resection of the he-patic caudate lobe was performed through the left and /or the right , the anterior liver-splitting or the retro-grade approaches .Results The mean operation time was (227 ±64) min.The mean amount of blood loss was (530 ±325) ml.The mean vascular occlusion time was (19.5 ±18.6) min.The mean diameter of ne-oplasm was (15 4.±9 .2) cm. All the operations were successfully carried out .There were no massive hem-orrhage, bile leakage or perioperative death .Hydrothorax occurred in 3 patients and ascites in 2.The mean stay in hospital was (21 ±9) days.All the patients were cured and discharged home .Conclusion Isolated complete resection of hepatic caudate lobe was feasible in clinical practice .

Objective To evaluate the safety of mesohepatectomy for centrally located large hepatic tumors.Methods The clinical data of 37 patients who underwent hepatectomy for centrally located large liver tumors in our hospital from October 2010 to August 2015 were retrospectively analyzed.During the operation,the left and right hemilivers were mobilized.Slings for the improved liver hanging maneuver and for selective hepatic vascular occlusion were placed.These slings were used when necessary in order to minimize occlusion and ischemia time to the residual liver,and to maximize the volume of functional liver remnant.Mesohepatectomy was carried out using a microwave hemostatic separator.The feasibility,its effects on preventing hemorrhage,the degree of liver damage and the postoperative complications were evaluated.Results The mean diameter of the neoplasms was (12.6 ± 7.2) cm.The vascular inflow occlusion time of the left and right hemilivers were (12.2 ±3.5) min and (18.5 ±7.1) min,respectively.The blood loss was (487 ± 352) ml.The amount of red blood cell transfusion was (2.7 ± 1.9) U.The operation time was (215 ± 72) min.TBIL,ALT and AST reached their peak levels on the 1 st day after operation and they were higher than before surgery (P ＜ 0.01).The levels were then significantly decreased on the 3rd day after operation.However,the TBIL (P ＜ 0.05),ALT (P ＜ 0.01) and AST (P ＜ 0.05) were higher than the preoperative level,and only returned to normal or were close to the preoperative value on the 7th day after operation (P ＞ 0.05).The initial increase in ALT was quick and then it slowed down,while the initial increase in AST was slow but it decreased quickly.Conclusions Mesohepatectomy for centrally located large hepatic tumors could safely be carried out using the liver hanging maneuver combined with selective hepatic vascular occlusion and a microwave hemostatic separator.This method has the advantages of causing less bleeding,liver damage and rapid recovery.
