Objective To approach the clinical effect，feasibility， and advantages and disadvantages of laparoscopic liver resection for liver tumor. Methods The clinical data of 32 patients with liver tumor underwent laparoscopic liver resection from January 2009 to August 2011 in this hospital were analyzed retrospectively. Results The laparoscopic liver resection of 32 patients with liver tumor were performed successfully，including 23 cases of primary liver cancer，5 cases of metastatic liver，3 cases of liver hemangioma，1 case of focal liver nodular hyperplasia. Laparoscopic liver resection included left lateral lobectomy （Ⅱ＋Ⅲ segments） in 17 cases，left internal lobectomy （Ⅳ segment） in 2 cases （left lateral lobe was already removed），left hemihepatectomy （Ⅱ＋Ⅲ＋Ⅳ segments） in 8 cases，Ⅴsegmentectomy in 1 case，and Ⅵ segmentectomy in 1 case，and Ⅲ，Ⅳ，and Ⅴ segments hemihepatectomy in 3 cases. The average operation time of hepatectomy was 75-285 min with an average 215 min. Intraoperative bleeding was 115-760 ml with an average 365 ml. No complications such as bile leakage，hemorrhage，air embolism, and so on happened. The time of gastrointestinal function recovery was 1-3 d. The hospital stay was 5-11 d with an average 6 d. Thirty-one cases were followed-up，the follow-up time was 6-32 months with an average 18 months，except one case was died of tumor recurrence and metastasis in one year after operation，the rest were alive，no tumor recurrence and metastasis happened. Conclusions Laparoscopic liver resection for liver tumor has a small wound，less suffering，quick recovery，which is safe and feasible. The clinical effect is good．
Objective To discussion the surgical approach of laparoscopic resection of left hepatic lobe. Methods The clinical data of 86 patients with Intr- and extra-hepatic bile duct stones and liver hemangioma were analyzed retros-pectivly. Eighty-six patients underwent laparoscopic hepatectomy. Forty-nine cases underwent the left hepatic lobe resectionby the left longitudinal groove （left longitudinal groove group）， 37 cases underwent the left hepatic lobe resection by the first hepatic portal （first porta hepatis group）. The operative time， intraoperative bleeding volume， postoperative hospital stay， and postoperative complications of two kinds of operation were compared. Results The operative time and intraoperative bleeding volume of left longitudinal groove group were shorter or less than those of the first porta hepatis group 〔（142±123）min vs. （208±58）min，P＜0.05； （320.5±38.3）mL vs. （450.9±39.1）mL，P＜0.05〕. There were no statistically significant difference between the 2 groups in complication and hospitalization after operation （P＞0.05）. Conclusion The left hepatic lobe resection by the left longitudinal groove is more safe and fast.
