OBJECTIVETo analyze operative and perioperative factors associated with hepatectomy.
METHODS2008 consecutive patients undergoing hepatectomy from January 1986 to December 2005 at Chinese People's Liberation Army General Hospital were investigated retrospectively according to their medical documentation. Diagnoses were made on basis of pathological results.
RESULTSMalignant and benign liver diseases accounted for 58.5% and 41.2%, respectively. In the former, primary liver cancer accounted for 76.1% and hilar cholangiocarcinoma for 6.7%. Hemangioma (41.7%) and hepatolithiasis (29.6%) were listed in the first two in the latter group with relatively more patient ratios. Isolated caudate lobe resection was performed in 25 patients and micro-wave inline coagulation was induced in 236 cases of liver resection. In all cases, those with blood loss less than 200 ml accounted for 50.5% (1015/2008), whereas those with more than 400 ml accounted for 28.4% (570/2008). In patients performed micro-wave inline coagulation liver resection, those with blood loss less than 200 ml and more than 400 ml accounted for 60.6% (143/236) and 19.9% (47/236), respectively, which differed significantly from the average level (P < 0.05). The postoperative complication incidence was 14.44% for all cases, 12.54% for primary liver cancer, 16.40% for secondary liver cancer, and 16.32% for hepatolithiasis. Complication incidence of primary liver cancer with tumor size smaller than 5 cm was 11.65% and that with tumor larger than 10 cm was 14.69%. There was no significant difference between the two groups. All-case hospital mortality was 0.55% and that for liver malignant disease was 0.60%, hilar cholangiocarcinoma 2.53%.
CONCLUSIONHepatectomy can be performed safely with low mortality and low complication incidence, provided that it is carried out with optimized perioperative management and innovative surgical technique.

This study was undertaken to analyze and evaluate the diagnosis and principal treatment methods for congenital choledochal cyst, focusing on various surgical procedures and clinical outcome. A comprehensive, retrospective study was conducted on 72 adult patients who presented with choledochal cyst from 1985 to 2002. Surgical procedures were cyst excision with hepaticojejunostomy in 25 cases for type I or type IV-B, extrahepatic cyst excision with hepaticojejunostomy in 8 cases for type IV-A, extrahepatic cyst excision with modified hepaticojejunostomy in 2 cases for type IV-B, non-cyst excision with or without hepaticojejunostomy in 27 cases for types I, II, IV-A, IV-B. The early postoperative morbidity and mortality rate were 16.1% (9/62) and 6.5% (4/62) respectively, and the complication rate related to surgical procedure was 30.6% (19/62). The incidence of cholangiocarcinoma with non-cyst excision or non-operated congenital choledochal cyst was 10.8% (4/37). One patient died of primary hepatocellular carcinoma after cyst excision with hepatojejunostomy. In conclusion, our results showed that complete exci-sion of choledochal cyst for types I, II, and IV-B and complete excision of extra-hepatic choledochal cyst from the hepatic hilum in type IV-A with hepaticojejunostomy or modified hepaticojejunostomy are the treatment of choice for choledochal cyst in adult patients.

OBJECTIVETo evaluate the effects of acute normovolemic hemodilution (ANH) combined with controlled hypotension on reducing heterogeneous transfusion and safety during liver tumorectomy.
METHODSThirty patients undergoing elective liver tumorectomy were randomly divided into 3 groups (10 each), namely ANH group (group A), ANH combined with controlled hypotension group (group B) and control group (group C). All the patients were anesthetized via endotracheal intubation. Before the operation, ANH was performed in groups A and B after anesthesia induction, and controlled hypotension was initiated in group B during tumorectomy. Blood transfusion and fluid infusion were carried out routinely in group C. Hb and Hct were measured before operation, after ANH, and immediately, 1 day and 7 days after the operation. The difference in intraoperative blood loss and heterogeneous blood transfusion volume in the 3 groups was observed.
RESULTSIn group A, heterogeneous blood transfusion was avoided in 6 cases and but given in the other cases for an average of 400 ml. In group C, every patient received heterogeneous blood transfusion (664.8-/+248.1 ml), but none of the patients received heterogeneous blood in group B. The difference in transfusion volume between the 3 groups was significant (P<0.01). Hemodynamics was basically stable during operation in the 3 groups.
CONCLUSIONANH combined with controlled hypotension is safe and effective for decreasing and even avoiding homologous blood transfusion in liver tumorectomy.

OBJECTIVETo evaluate the combinated transcatheter hepatic artery chemoembolization (TACE) and analyse the factors affecting prognosis in patients with primary hepatic carcinoma.
METHODS141 consecutive patients with primary hepatic carcinoma were treated, including 125 men and 16 women (mean age, 52 years; age range, 21 - 76 years). Combinated TACE procedures included TACE, TACE followed by surgical resection, TACE and percutaneous ethanol injection (PEI) and transcatheter hepatic artery infusion (TAI). The factors included sex, age, ALT, AFP, HBsAg, liver function (Child's system), the way of treatment, tumor size and number, serum albumin, portal cancerous thrombus, pathological type of tumors, and HBeAg. The Cox's regression analysis model was used to analyse the factors affecting the prognosis. P < 0.05 means statistically significant difference.
RESULTSThe total median survival time was 19 months and mean survival time 23.59 months. The total survival rates of 1, 2, 3, 5 years were 63.9%, 44.5%, 25.8% and 7.4%, respectively. Multivariable analysis revealed significant prognostic factors as follows: age, liver function, the way of treatment, portal cancerous thrombus and pathological types of tumors (chi2 = 45.993, P = 0.0001).
CONCLUSIONThe combinated TACE procedure is safe and effective. In this study, 5 factors directly influencing the prognosis are age, liver function, portal cancerous thrombus and pathological types of tumors are risk prognostic factors, and the way of treatment is a protective factor (chi2 = 45.993, chi2 = 0.0001).
