Intravascular papillary endothelial hyperplasia (Masson's hemangioma) is a disease characterized by exuberant endothelial proliferation within the lumen of medium-sized veins. In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis. The lesion has a propensity to occur in the head, neck, fingers, and trunk. Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date. The authors have experienced intravascular papillary endothelial hyperplasia of the liver in a 69-yr-old woman, and report the case with a review of the literature.

OBJECTIVE:
To explore the technique and effect of liver hanging maneuver in anterior approach for isolated complete liver caudate lobectomy.
METHODS:
We recruited 17 patients with liver caudate lobe tumor (13 primary hepatocellular carcinoma, 3 cholangiocarcinoma and 1 liver metastasis from colorectal cancer). Isolated complete caudate lobectomy with liver hanging maneuver was performed in 17 patients.
RESULTS:
All 17 patients were successfully received the above-mentioned operation. The operative time was 166-427 (211.5 ± 20.1) min and the intraoperative blood loss was 372-1 208 (472.7 ± 83.6) mL. There was no operative death. The survival rates of follow up for 1, 3 and 5 years were 76.5%, 52.9% and 23.5%, respectively.
CONCLUSION
Liver hanging maneuver for isolated complete resection of the caudate lobe is an ideal approach for liver neoplasms resection.

OBJECTIVETo assess the feasibility and the significance of surgical resection of small intrahepatic lesions adjacent to the major vasculature.
METHODSThe results of treatment were retrospectively reviewed in 40 patients who received operation for intrahepatic lesions less than 3 cm in diameter between Jan. 2003 and Dec. 2005. The lesions were all adjacent to the major vasculature in the liver.
RESULTSIn the 40 patients, a total of 44 small intrahepatic lesions were successfully resected with minimal morbidity and blood loss (mean 163 ml). A second lesion was found in 4 patients (10%) during intraoperative exploration. Histologically the lesion was malignant in 29 cases (including 4 cases with two lesions) and benign in 11 cases, with correct preoperative diagnosis in 62.5% of all cases. For 26 patients with hepatocellular carcinoma, the 1-, 2-, and 3-year postoperative survival rates were 90.1%, 83.2% and 64.7%, respectively, while the patients with benign lesions were cured with the operation.
CONCLUSIONSSurgical resection of small intrahepatic lesions adjacent to the major vasculature is demanding but feasible and with satisfying effect. The significance of surgical management of these small lesions is not only excising the lesions but also making definite diagnosis and finding new lesions in some patients.

OBJECTIVE:
To evaluate the highly-selective regional vascular exclusion in the risk hepatectomy for liver tumor.
METHODS:
Short hepatic veins were ligated and divided followed by the dissection, and isolation of the inflow and outflow vessels of the tumor-bearing lobe, which were completely devascularized after the occlusion of these vessels. The blood loss volume, postoperative recovering situation of the liver function and the incidence of complication were observed in 68 cases.
RESULTS:
Main hepatic veins were dissected and isolated exo-hepatically in 65 cases. In the other 3 cases, the main hepatic veins were blocked by Satin skin clamp applied longitudely along the inferior vena cava. Hepatic pedicle was routinely excluded.The amount of blood loss was from 400 to 1200 (600+/-200) mL and 26 (65%) cases didn't receive transfusion.There was no operative mortality and liver function failure. Surgical complications included subphrenic abscess in 2 cases and bile leakage in 2 cases, which were cured conservatively.
CONCLUSION
Highly-selective regional exclusion of hepatic blood flow during the risk hepatectomy is safe and effective to prevent massive bleeding and to reduce the incidence of liver failure.

OBJECTIVETo investigate the resection technique for small hepatocellular carcinoma (SHCC) in special sites and discuss their outcome.
METHODSClinicopathological data of 30 patients with SHCC in special sites undergone liver resection were reviewed. There were 29 cases of hepatocellular carcinoma and 1 case of cholangiocarcinoma, confirmed by pathology. The tumor was close to the first porta hepatis in 8 cases, colse to the second porta hepatis in 15 cases, and close to the third porta hepatis in 7 cases. Twenty-five patients had one lesion, 4 patients had two and the other had three. The tumor diameter was (2.7 ± 1.2) cm.
RESULTSNo perioperative death occurred. The operation time was (279 ± 101) min, the mean intraoperative blood loss was 566 ml, and the postoperative hospitalization was (10.5 ± 2.7) days. The 1- and 3-year survival rates were 100% and 83.3%, respectively, and the 1- and 3-year disease free survival rates were 85.0% and 41.3%, respectively.
CONCLUSIONAlthough the surgery for SHCC in special sites is quite difficult and risky, surgical treatment is still safe with good perioperative management and is an effective treatment of SHCC in special sites.

BACKGROUNDLaparoscopic liver resection (LLR) has been considered to be safe and feasible. However, few studies focused on the comparison between the anatomic and nonanatomic LLR. Therefore, the purpose of this study was to compare the perioperative factors and outcomes of the anatomic and nonanatomic LLR, especially the area of liver parenchymal transection and blood loss per unit area.
METHODSIn this study, surgical and oncological data of patients underwent pure LLR procedures for malignant liver tumor were prospectively collected. Blood loss per unit area of liver parenchymal transection was measured and considered as an important parameter. All procedures were conducted by a single surgeon.
RESULTSDuring nearly 5 years, 84 patients with malignant liver tumor received a pure LLR procedure were included. Among them, 34 patients received anatomic LLR and 50 received nonanatomic LLR, respectively. Patients of the two groups were similar in terms of demographic features and tumor characteristics, despite the tumor size was significantly larger in the anatomic LLR group than that in the nonanatomic LLR group (4.77 ± 2.57 vs. 2.87 ± 2.10 cm, P = 0.001). Patients who underwent anatomic resection had longer operation time (364.09 ± 131.22 vs. 252.00 ± 135.21 min, P < 0.001) but less blood loss per unit area (7.85 ± 7.17 vs. 14.17 ± 10.43 ml/cm 2 , P = 0.018). Nonanatomic LLR was associated with more blood loss when the area of parenchymal transection was equal to the anatomic LLR. No mortality occurred during the hospital stay and 30 days after the operation. Moreover, there was no difference in the incidence of postoperative complications. The disease-free and overall survival rates showed no significant differences between the anatomic LLR and nonanatomic LLR groups.
CONCLUSIONSBoth anatomic and nonanatomic pure LLR are safe and feasible. Measuring the area of parenchymal transection is a simple and effective method to estimate the outcomes of the liver resection surgery. Blood loss per unit area is an important parameter which is comparable between the anatomic LLR and nonanatomic LLR groups.

BACKGROUNDHepatoblastoma (HB) is a rare childhood tumor. We investigated the effect of intraoperative management of the intrahepatic major vessels in children with HB.
METHODSBetween April 2005 and August 2012, surgical resection was performed on 50 children with hepatoblastoma. These children were divided into a vessel-ligation group (n = 20) and a vessel-repair group (n = 30). In the vessel-ligation group, the intrahepatic major vessels were ligated and removed together with the tumor and the affected liver lobe/liver parenchyma. In the vessel-repair group, the affected intrahepatic major vessels were dissected and preserved as much as possible and the normal liver lobe/liver parenchyma and blood supply from these vessels were also preserved. The outcomes were analyzed by postoperative follow-up.
RESULTSIn the vessel-ligation group, two patients gave up surgery, six patients underwent palliative resection, and 12 patients underwent en bloc resection; four patients died of liver failure and eight patients fully recovered and were discharged. In the vessel-repair group, all 30 patients underwent en bloc resection and were discharged after satisfactory healing. After a follow-up time of 5 - 36 months (median: 20 months), two patient in the vessel-ligation group survived and 22 patients in the vessel-repair group survived.
CONCLUSIONSPatients with HB can be successfully treated by tumor resection with vascular repair. This method prevents postoperative liver failure, ensures patient safety during the perioperative period, and allows for early chemotherapy.

OBJECTIVETo explore the value of ultrasound-guided percutaneous radiofrequency ablation (RFA) in designing the indication, treatment protocol and operational skills for patients with primary hepatocellular carcinoma (HCC) near the liver surface.
METHODSSixty-one HCC patients with 69 lesions, confirmed by clinical examination and pathology, underwent percutaneous radiofrequency ablation. The study included 40 cases of liver function Child-Pugh grade A and 21 cases of grade B. The average size of tumors was (3.8 ± 1.2) cm, tumor diameter ≥ 4 cm accounted for 39.1% (27/69 lesions), and the average age was 58.2 years (range, 35-76 years). Taking comprehensive measures, such as intraperitoneal injection of saline adjacent to the tumor before RFA, increasing the puncture sites on the surface of tumor to avoid overlapping of the central portion of tumor, repeated ablation of the needle track to reduce needle tract metastasis, avoid vertical puncture, and other additional measures, to improve the inactivation of tumors adjacent to the liver surface. Enhanced CT/MRI was performed to evaluate the curative effect at 1, 3, 6 and 24 months after the treatment.
RESULTSThe inactivation rate of tumor was 98.6% (68/69 lesions) and local recurrence rate was 5.8%(4/69) after RFA. The tumor-related marker AFP was 1 000-1 500 ng/ml before and reduced to (98.5 ± 42.5) ng/ml after radiofrequency ablation, among them returned to normal in 13 cases (21.3%). Since the ablation area was rather small, the level of serum alanine aminotransferase was elevated only to (148.5 ± 38.5) U/ml at one week after RFA and returned to normal at (1.8 ± 0.6) week after RFA. No patient experienced severe liver dysfunction. The local HCC recurrent rate after RFA was 5.8%(4/69 lesions) and intrahepatic heterotopic recurrence rate was 24.6% (15/61). The 20-61 months follow-up showed that the 1-, 2- and 3-year survival rate was 83.6%, 57.3% and 44.2%, respectively.
CONCLUSIONSUltrasound-guided percutaneous radiofrequency ablation provides an effective minimally invasive treatment for primary HCC near the liver surface. Taking some additional measures such as intraperitoneal injection of saline, increase of percutaneous puncture sites, and avoiding vertical needle puncture, may reduce complications and improve the therapeutic outcome. RFA is one of effective and minimally invasive treatment and causing less liver damage for primary HCC near the liver surface.

OBJECTIVETo explore the role of extrahepatic control on blood flow of hepatic vein and inferior vena cava in hepatectomy, and observe its effect on minimizing hemorrhage.
METHODSFrom 2001 to April 2003, 33 patients who had liver tumors involving segment IV, VII, VIII or half liver underwent major hepatectomies that required exposure of the inferior vena cava and main trunks of hepatic veins, during which the major hepatic veins and inferior vena cava were isolated and taped to control blood flow when necessary.
RESULTSIn 33 attempts, 32 were successful and all tumors were resected successfully. The placement of occlusion tape was unsuccessful in 1 case. 7 cases did not need blood transfusion during operation. The amount of blood transfusion for other cases were form 0 to 1 600 ml. there was no operative mortality.
CONCLUSIONSAppropriate control of main truck of hepatic vein and inferior vena cava is effective in reducing blood loss during hepatectomies. It is also very helpful for performing difficult hepatectomies.
