Objective To state operative details of lip-shaped hepatectomy (LSH) and evaluate its advantage in treatment of primary liver cancer (PLC).Methods LSH is one of the irregular hepatectomies. The key lies in the following five operative kinks: ①adequately mobilizing perihepatic ligaments; ②designing lip-shaped hepatic incision; ③laying sutures on both sides of the hepatic incision for traction; ④wedge-shapedly resecting the tumor and the surrounding liver; ⑤closely sewing up the hepatic cutting surface.Results Two hundreds and thirty three patients with PLC were treated by LSH between Oct. 1991 and Dec. 1997 in Zhongshan hospital, Shanghai medical university. Among them 8 cases underwent initial hepatectomy and resection for recurrence of the tumor. The operative mortality rate was 1.2%, 2 died of hepatic failure and 1 renal failure. In addition to bile leakage in 3 cases and hydropsy at the operative area in one case, no severe postoperative complications were found, such as intraperitoneal bleeding, subphrenic abscess and so on. The 1-,3-,5-year survival rates were 89.8%, 64.3% and 55.9% respectively, in 233 patients with 241 LSHs. 25 patients survived more than 5 years. The result indicated that the most advantage of LSH was to increase operative safety on the basis of guarantee of radical resection of PLC, especially to decrease some complications from hepatic cutting surface.Conclusion LSH is a relatively simple, safe, reasonable and recommendable hepatectomic modality.
One hundred and five hepatic resection were performed from 1984 to 1994. Six of these patients complicated with subphrenic infection after hepatectomy, of whom two patients died of liver failure. Subphrenic dropsy occureeed in nine cases. Subphrenic infection is easy to occur in: right or extend lobectomy, massive blood loss at operation, and in postoperative bleeding which subjects to laparotomy for lemostasis. Seecure hemostasis, avoidence of hepatic tissue devitalization during operation and effective subphenic drainage aree essential to reduce the incidencee of subphrenic infection, and routine bacterial culture of subphrenic drainage fluid will help to select propre antibiotic.
Objective To explore the value of laparoscopic hepatectomy for small hepatocellular carcinoma (HCC) of non-peripheral type. Methods The clinical data of 34 patients with small HCC of non-peripheral type underwent laparoscopic liver resection from March 2008 to April 2011 in our hospital were analyzed retrospectively. Results Thirty-two patients received successful total laparoscopic hepatectomy without blockage of liver blood flow，and 2 were converted to open surgery. The operative time was （162±65） min （100-220 min） and the blood loss was （295±166） ml （100-750 ml）. There were postoperative complications in 4 patients， included cross-section bleeding in 2 cases and ascites in 2 cases. There were no complications such as biliary fistula， infection， carbon dioxide gas embolism， and so on. The mortality of perioperative period was 0. The postoperative hospital stay was （6±2） d （4-9 d）. The follow-up time was （23±7） months （5-42 months）. Thirteen patients developed intrahepatic tumor recurrence during follow-up. The overall and recurrence-free survival rate one year after operation was 90.6% （29/32）and 75.0% （24/32）， respectively. Conclusions Laparoscopic hepatectomy is a safe， feasible， and minimal invasive approach for small HCC of non-peripheral type，and it can be considered as a alternative treatment of HCC.
Objective To explore the curative effect of surgical treatment for primary liver cancer with portal vein tumor thrombus（PVTT）. Methods The clinical data of 227 patients who were performed surgical treatment because of primary liver cancer with PVTT were analyzed retrospectively. Results Two hundreds and seventeen cases were performed surgical resection, 14 cases died from postoperative complications. The median survival time was 17.7 months, and the l-, 2-, 3-, and 5-year survival rates were 61.9%, 37.2%, 21.7%, and 4.0% respectively. There were 40 cases with PVTT ofⅠtype, the l-, 2-, 3-, and 5-year survival rates were 82.3% , 61.7%, 38.6%, and 6.6% respectively，which was obviously higher than those with PVTT of Ⅱ type （n=129, 61.1%, 34.3%, 20.8%, and 5.3%） and PVTT of Ⅲ type （n=48, 46.8%, 24.0%, 9.6%, and 0）, P＜0.05. There were 84 cases whose PVTT and tumor were resected together, the l-, 2-, 3-, and 5-year survival rates were 67.3%, 43.2%, 28.1%, and 7.9% respectively，which were obviously higher than those patients whose PVTT were removed from cross-section of liver （n= 85, 65.1%, 38.8%, 22.3%, and 3.4%） and patients whose PVTT were removed by cutting the portal vein （n=48, 46.8%, 24.0%, 9.6%, and 0）, P＜0.05. The l-, 2-, 3-, and 5-year survival rates of 76 cases who received postoperative therapy of TACE/TAI were 75.3%, 53.2%, 33.1%, and 5.7% respectively, which were obviously higher than those patients who were not received any postoperative therapy （n=141, 54.8%, 29.1%, 15.9%, and 3.2%）, P＜0.05. Conclusions Surgical treatment is an effective treatment for primary liver cancer with PVTT. Surgery should strive for resecting the tumor and PVTT together, and postoperative therapy of TACE/TAI may have a favorable effect on the long term survival rate.
Objective To investigate the technique and feasibility of hepatic pedicle vascular control in laparoscopic hepatectomy. Methods From May 2005 to June 2011, 95 cases of hepatectomies were performed by laparoscopy in the Department of Minimally Invasive Surgery, The First Affiliated Hospital, Guangxi Medical University.The characteristics of these cases were analyzed. Results Left lateral segmentectomy were required in 21 patients, left hepatectomy in 13 patients, right hepatectomy in 4 patients, segmentectomy in 17 patients, tumor resection in 24 patients,hemangioma resection in 5 patients, and conversions to laparotomy in 11 patients.

The selective vascular control of inflow were performed in 56 patients， the technique included intrahepatic Glisson approach in 14 patients and controlling hepatic artery and portal vein separately in 42 patients. Pre-parenchymal transection control of hepatic outflow were performed in 12 patients, included the left hepatic vein were controlled by suturing or separating in 11 patients and right hepatic vein was controlled by separating in 1 patient. Others were controlled intraparenchymally during transection. The mean operative time was （236.80±95.97） min，mean operative blood loss was（ 551.55±497.41） ml， concentrate red blood cells transfusion volume was（ 2.60±2.23） U， and plasma transfusion volume was （211.90±179.29） ml. The postoperative complications included bleeding in 4 patients, pleural effusion in 4 patients, pneumonia in 3 patients, ascites in 7 patients, and biliary fistula in 2 patients, and dead in 1 patient. The mean hospitalization time was（ 12.47±4.18） days. At the deadline（ February 2012）, 72 cases with liver cancer were followup. The follow-up time ranged from 5 to 81 months and the mean time was（ 24.14±16.62） months， where survival rate was 68.4%（ 54/79） of 1-year and 21.5%（ 17/79） of 3-year. Conclusions The application of hepatic pedicle vascular control in laparoscopic hepatectomy is feasible.
Objective To evaluate the effect of pulse dye-densitometry by indocyanine green test (PDD-ICG)on the assessment of hepatic function reserve. MethodsSeventy-five hepatic carcinoma patients aimed to accept hepatectomy from March 2007 to February 2008 at West China Hospital were prospectively included in this study.Patients were grouped by dysfunction grade of hepatic function and the indexes before operation were compared.Furthermore, patients were grouped by K and R15 value to compare the moderate and severe liver dysfunction ratio, respectively. ResultsSixty cases manifested slight liver dysfunction,12 cases manifested moderate liver dysfunction,and 3 cases manifested severe liver dysfunction(the latter was took into moderate group due to the cases were too few).The difference of Child-Pugh score and common liver function examination indexes such as PT and INR before operation was not significant betweentwo groups(P＞0.05).ButPDD-ICG experiment indexes(K and R15)were remarkable different betweentwo groups(P＜0.05).The patients were divided into two groups according to K and R15 value,respectively.The rate of moderate and severe liver dysfunction was significant different between K＜0.158/min groupand K≥0.158/min group(47.1% vs. 12.1%,P＜0.05),and likewise moderate and severe liver dysfunction was significant different between R15≤10% group and R15＞10% group(15.9% vs.41.7%,P＜0.05）. ConclusionPDD-ICG is an effective and easyto evaluate hepatic function reserve of patient undergone hepatectomy.Therefore,it may give clinical instruction to predict and avoid the liver dysfunction after operation.
Objective To approach the indications， techniques features， and efficacy of laparoscopic hepatectomy for liver tumor. Methods The clinical data and follow-up results of 61 patients who received laparoscopic hepatectomy at our institute from January， 2007 to December， 2012 were retrospectively analyzed. Results Of the 61 patients， 16 cases were with primary liver cancer， 1 case with liver adenocarcinoma， 2 cases with metastatic liver cancer， 31 cases with hepatic hemangioma， and 11 cases with other benign liver diseases （including hepatocellular adenoma， focal nodular hyperplasia， hepatic cysts， and mucinous cystadenoma）. The average tumor diameter was 5.6 cm （2-15 cm）. The surgical approaches includes laparoscopic hepatic left lateral lobectomy （42 cases）， right posterior lobectomy （2 cases）， hepatectomy of segmentⅥ （3 cases）， hepatectomy of segmentsⅦ/Ⅷ， Ⅳa， and caudate lobe （one respectively）. Non-anntomic and wedge resection were performed on 11 patients. The mean operating time， blood loss， postoperative hospital stay， and postoperative complication rate were （124±65） min （50-200min）， （251±145） mL （50-1 000mL），（7.3±3.6） d （4-11d）， and 16.3% （10/61）， respectively. In 19 cases with malignant liver lesions， 15 cases were followed up mean for 26 months （1-48 months）. One of them died in 1 year after operation for multiple organ dysfunction， others were survival. Conclusions Experienced laparoscopic surgery doctors selected appropriate cases， used proper blood inflow oclussion and liver resction methods， and cared for tumor-free principle， the laparoscopic hepatectomy for malignant and benign tumors of liver could be safe and effective to carry out.
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.
The treatment of liver cancer is still a challenge in the world, and it is mainly refers to hepatocellular carcinoma (HCC). There are many factors affecting the overall survival rate of HCC; the recurrence of HCC is the main risk factor affecting the survival of patients, hence, it is urgent to explore the clinical treatment of recurrent HCC to obtain long-term survival of the patients. Up to now, surgical treatment is a radical treatment for HCC. Similarly, liver resection and liver transplantation are still the main therapy methods for recurrent HCC. In addition, radiofrequency ablation and transcatheter arterial chemoembolization and other local treatments still play an irresistible role. Therefore, emphasizing the postoperative follow-up of patients, diagnosing recurrent HCC in early stage, paying attention to the risk factors of HCC recurrence and selecting a suitable treatment plan for individuals are critical ways to prolong the survival of patients.
