Abstract: Objective: To investigate an optimum method for left hepatolith to improve the operation response. Methods: Sixty-three cases of left hepatolith underwent operations of left-half hepatectomy, Roux-en-Y cholangio-jejunostomy and removal of stones by cholangiotomy under the condition of hemihepatic blood flow occlusion at normal atmospheric temperature. The postoperative complications, the index of liver function, the recurrent rate and the re-operation rate were evaluated. Results: No one died during the operations and the postoperative recovery rate, the improvement rate and the residual rate were 82.4%, 17.6% and 8.3%, respectively. Complications were found in 23 cases, biliary fistula in 2 cases, subphrenic infection in 4, incisional wound infection in 9, transaminase lifting in 6 and digestive tract bleeding in 2, but they were all cured by non-operative treatment. During 1-8 years of follow-up, 87.7% of the cases were rechecked by ultrasonic diagnosis B, CT and liver function test, and 6 of them had relapsed. Conclusion: The hemihepatic blood flow occlusion for hepatectomy is a feasible, reasonable and effective procedure due to good control of blood loss, retention of blood circulation in the healthy liver side, and lessening of intra-operation and post-operation liver dysfunction.
