Autologous blood storage before hepatectomy for hepatocellular carcinoma with underlying liver disease

BACKGROUND: Preoperative autologous blood donation has been suggested for patients with liver disease who are to undergo liver resection. The aim of this retrospective study was to clarify the risk factors for increased blood loss and the need for blood transfusion during hepatectomy for hepatocellular carcinoma (HCC). METHODS: From January 1996 to December 2000, 206 consecutive patients, 98.5 per cent of whom had underlying liver disease, underwent elective hepatectomy for HCC. RESULTS: Major hepatectomy was performed in 34 patients (16.5 per cent) and minor hepatectomy in 172 patients (83.5 per cent). The mean blood loss was 410 (median 260) ml. Eleven (5.3 per cent) of the 206 patients received blood transfusion during or after the operation. Operation time (P = 0.004) and central venous pressure (CVP) (P = 0.041) were independently correlated with blood loss of more than 1000 ml. Only preoperative haemoglobin level (P = 0.001) was independently correlated with the need for blood transfusion. CONCLUSION: In patients with underlying liver disease, maintaining CVP at a level below 5 cm H2O during parenchymal transection to reduce blood loss is more important than reserving autologous blood before the operation.     

Major hepatectomy for hepatocellular carcinoma in patients with an unsatisfactory indocyanine green clearance test.

BACKGROUND: Liver failure is the commonest cause of postoperative death in patients with hepatocellular carcinoma (HCC). With the improvement in operative technique and perioperative care, the limit of hepatic functional reserve may be lowered. The aim of this study was to evaluate the postoperative morbidity, mortality and survival rates in patients with an indocyanine green (ICG) retention value higher than 14 per cent, after major hepatectomy for HCC. METHODS: From January 1994 to December 1997, 117 patients underwent major hepatectomy for HCC; 92 patients had preoperative ICG retention at 15 min lower than 14 per cent (median 8.3 (range 1.6-13.8) per cent), while 25 patients had ICG retention greater than 14 per cent (17.4 (range 14.3-35.3) per cent). Data were collected prospectively and analysed retrospectively. RESULTS: The two groups of patients were similar in terms of age, sex ratio, preoperative platelet count, liver biochemistry, Child-Pugh status and operative procedures performed, but the prothrombin time was significantly longer in the high ICG group. The operative blood loss (1.5 litres), the amount of blood transfused and the number of patients requiring blood transfusion were similar. The postoperative complication rate (41 versus 40 per cent), duration of hospital stay (12 versus 13 days), hospital mortality rate (1 versus 4 per cent) and median survival time (47 versus 45 months) were not significantly different. CONCLUSION: With meticulous surgical technique to decrease intraoperative blood loss and good perioperative care, selected patients with limited hepatic functional reserve can achieve a good immediate postoperative result and a survival rate similar to that of patients with good hepatic functional reserve.     

Hepatectomy for hepatocellular carcinoma: toward zero hospital deaths

OBJECTIVE: The authors report on the surgical techniques and protocol for perioperative care that have yielded a zero hospital mortality rate in 110 consecutive patients undergoing hepatectomy for hepatocellular carcinoma (HCC). The hepatectomy results are analyzed with the aim of further reducing the postoperative morbidity rate. SUMMARY BACKGROUND DATA: In recent years, hepatectomy has been performed with a mortality rate of <10% in patients with HCC, but a zero hospital mortality rate in a large patient series has never been reported. At Queen Mary Hospital, Hong Kong, the surgical techniques and perioperative management in hepatectomy for HCC have evolved yearly into a final standardized protocol that reduced the hospital mortality rate from 28% in 1989 to 0% in 1996 and 1997. METHODS: Surgical techniques were designed to reduce intraoperative blood loss, blood transfusion, and ischemic injury to the liver remnant in hepatectomy. Postoperative care was focused on preservation and promotion of liver function by providing adequate tissue oxygenation and immediate postoperative nutritional support that consisted of branched-chain amino acid-enriched solution, low-dose dextrose, medium-chain triglycerides, and phosphate. The pre-, intra-, and postoperative data were collected prospectively and analyzed each year to assess the influence of the evolving surgical techniques and perioperative care on outcome. RESULTS: Of 330 patients undergoing hepatectomy for HCC, underlying cirrhosis and chronic hepatitis were present in 161 (49%) and 108 (33%) patients, respectively. There were no significant changes in the patient characteristics throughout the 9-year period, but there were significant reductions in intraoperative blood loss and blood transfusion requirements. From 1994 to 1997, the median blood transfusion requirement was 0 ml, and 64% of the patients did not require a blood transfusion. The postoperative morbidity rate remained the same throughout the study period. Complications in the patients operated on during 1996 and 1997 were primarily wound infections; the potentially fatal complications seen in the early years, such as subphrenic sepsis, biliary leakage, and hepatic coma, were absent. By univariate analysis, the volume of blood loss, volume of blood transfusions, and operation time were correlated positively with postoperative morbidity rates in 1996 and 1997. Stepwise logistic regression analysis revealed that the operation time was the only parameter that correlated significantly with the postoperative morbidity rate. CONCLUSION: With appropriate surgical techniques and perioperative management to preserve function of the liver remnant, hepatectomy for HCC can be performed without hospital deaths. To improve surgical outcome further, strategies to reduce the operation time are being investigated.     

Influence of postoperative morbidity on long-term survival following liver resection for colorectal metastases

BACKGROUND: Survival after resection of colorectal liver metastases may be influenced by the patient, the primary tumour and the liver metastases. Postoperative morbidity is associated with poor survival in several cancers. The aim of this retrospective study was to evaluate prognostic factors of survival after resection of colorectal liver metastases, including postoperative morbidity. METHODS: From 1985 to 2000, 311 consecutive patients with liver metastases from colorectal cancer underwent resection with curative intent. Univariate and multivariate analyses were performed to assess the influence of age, sex, site and stage of the colorectal tumour, disease-free interval, number, size and distribution of metastases, type of hepatectomy, pedicular clamping, resection margin, blood transfusion, postoperative morbidity and adjuvant chemotherapy on overall and disease-free survival. RESULTS: The postoperative mortality and morbidity rates were 3 and 30 per cent respectively. The 3- and 5-year overall survival rates were 53 and 36 per cent respectively. Both overall and disease-free survival rates were independently associated with nodal status of the colorectal tumour, number of metastases and postoperative morbidity. Patients with postoperative morbidity had an overall and disease-free 5-year survival rate half that of patients with no morbidity: 21 versus 42 per cent for overall survival (P < 0.001) and 12 versus 28 per cent for disease-free survival (P = 0.001) respectively. CONCLUSION: Long-term survival can be altered by postoperative morbidity after resection of colorectal liver metastases by increasing the risk of tumour recurrence. This justifies optimizing the surgical treatment of colorectal liver metastases to decrease postoperative morbidity and the use of efficient adjuvant treatments in patients with postoperative morbidity.     

Effects of the combination of blood transfusion and postoperative infectious complications on prognosis after surgery for colorectal cancer. Danish RANX05 Colorectal Cancer Study Group

BACKGROUND: The frequency of postoperative infectious complications is significantly increased in patients with colorectal cancer receiving perioperative blood transfusion. It is still debated, however, whether perioperative blood transfusion alters the incidence of disease recurrence or otherwise affects the prognosis. METHODS: Patient risk variables, variables related to operation technique, blood transfusion and the development of infectious complications were recorded prospectively in 740 patients undergoing elective resection for primary colorectal cancer. Endpoints were overall survival (n = 740) and time to diagnosis of recurrent disease in the subgroup of patients operated on with curative intention (n = 532). The patients were analysed in four groups divided with respect to administration or not of perioperative blood transfusion and development or non-development of postoperative infectious complications. RESULTS: Overall, 19 per cent of 288 non-transfused and 31 per cent of 452 transfused patients developed postoperative infectious complications (P< 0.001). The median observation period was 6.8 (range 5.4-7.9) years. In a multivariate analysis, risk of death was significantly increased among patients developing infection after transfusion (n = 142) compared with patients receiving neither blood transfusion nor developing infection (n = 234): hazard ratio 1.38 (95 per cent confidence interval (c.i.) 1.05-1.81). Overall survival of patients receiving blood transfusion without subsequent infection (n = 310) and patients developing infection without preceding transfusion (n = 54) was not significantly decreased. In an analysis of disease recurrence the combination of blood transfusion and subsequent development of infection (hazard ratio 1.79 (95 per cent c.i. 1.13-2.82)), localization of cancer in the rectum and Dukes classification were independent risk factors. CONCLUSION: Blood transfusion per se may not be a risk factor for poor prognosis after colorectal cancer surgery. However, the combination of perioperative blood transfusion and subsequent development of postoperative infectious complications may be associated with a poor prognosis.     

Is extended hepatectomy for hepatobiliary malignancy justified?

BACKGROUND: Extended hepatectomy may be required to provide the best chance for cure of hepatobiliary malignancies. However, the procedure may be associated with significant morbidity and mortality. METHODS: We analyzed the outcome of 127 consecutive patients who underwent extended hepatectomy (resection of > or = 5 liver segments) for hepatobiliary malignancies. RESULTS: The patients underwent extended hepatectomy for colorectal metastases (n = 86; 67.7%), hepatocellular carcinoma (n =12; 9.4%), cholangiocarcinoma (n =14; 11.0%), and other malignant diseases (n =15; 11.5%). Thirty-two left and ninety-five right extended hepatectomies were performed. Eight patients also underwent caudate lobe resection, and 40 patients underwent a synchronous intraabdominal procedure. Twenty patients underwent radiofrequency ablation, and 31 underwent preoperative portal vein embolization. The median blood loss was 300 mL for right hepatectomy and 600 mL for left hepatectomy (P = 0.02). Thirty-six patients (28.3%) received a blood transfusion. The overall complication rate was 30.7% (n = 39), and the operative mortality rate was 0.8% (n = 1). Significant liver insufficiency (total bilirubin level > 10 mg/dL or international normalized ratio > 2) occurred in 6 patients (4.7%). Multivariate analysis showed that a synchronous intraabdominal procedure was the only factor associated with an increased risk of morbidity (hazard ratio [HR], 4.9; P = 0.02). The median survival was 41.9 months. The overall 5-year survival rate was 25.5%. CONCLUSIONS: Extended hepatectomy can be performed with a near-zero operative mortality rate and is associated with long-term survival in a subset of patients with malignant hepatobiliary disease. Combining extended hepatectomy with another intraabdominal procedure increases the risk of postoperative morbidity.     

Improving perioperative outcome expands the role of hepatectomy in management of benign and malignant hepatobiliary diseases: analysis of 1222 consecutive patients from a prospective database

OBJECTIVE: To assess the trends in perioperative outcome of hepatectomy for hepatobiliary diseases. METHODS: Data of 1222 consecutive patients who underwent hepatectomy for hepatobiliary diseases from July 1989 to June 2003 in a tertiary institution were collected prospectively. Perioperative outcome of patients in the first (group I) and second (group II) halves of this period was compared. Factors associated with morbidity and mortality were analyzed. RESULTS: Diagnoses included hepatocellular carcinoma (n = 734), other liver cancers (n = 257), extrahepatic biliary malignancies (n = 43), hepatolithiasis (n = 101), benign liver tumors (n = 61), and other diseases (n = 26). The majority of patients (61.8%) underwent major hepatectomy of > or = 3 segments. The overall hospital mortality and morbidity were 4.9% and 32.4%, respectively. The number of hepatectomies increased from 402 in group I to 820 in group II, partly as a result of more liberal patient selection. Group II had more elderly patients (P = 0.006), more patients with comorbid illnesses (P = 0.001), and significantly worse liver function. Nonetheless, group II had lower blood loss (median 750 versus 1450 mL, P < 0.001), perioperative transfusion (17.3% versus 67.7%, P < 0.001), morbidity (30.0% versus 37.3%, P = 0.012), and hospital mortality (3.7% versus 7.5%, P = 0.004). On multivariate analysis, hypoalbuminemia, thrombocytopenia, elevated serum creatinine, major hepatic resection, and transfusion were the significant predictors of hospital mortality, whereas concomitant extrahepatic procedure, thrombocytopenia, and transfusion were the predictors of morbidity. CONCLUSIONS: Perioperative outcome has improved despite extending the indication of hepatectomy to more high-risk patients. The role of hepatectomy in the management of hepatobiliary diseases can be expanded. Reduced perioperative transfusion is the main contributory factor for improved outcome.     

Efficacy and safety of radiofrequency ablation for perivascular hepatocellular carcinoma without hepatic inflow occlusion

BACKGROUND: The role of radiofrequency ablation (RFA) for perivascular (up to 5 mm from the major intrahepatic portal vein or hepatic vein branches) hepatocellular carcinoma (HCC) is unclear because of possible incomplete tumour ablation and potential vascular damage. This study aimed to evaluate the safety and efficacy of RFA for perivascular HCC without hepatic inflow occlusion. METHODS: Between May 2001 and November 2003, RFA using an internally cooled electrode was performed on 52 patients with perivascular HCC (group 1) through open (n = 39), percutaneous (n = 9), laparoscopic (n = 2) and thoracoscopic (n = 2) approaches. Hepatic inflow occlusion was not applied during the ablation procedure. The perioperative and postoperative outcomes were compared with those of 90 patients with non-perivascular HCC (group 2) treated by RFA during the same period. RESULTS: The morbidity rate was similar between groups 1 and 2 (25 versus 28 per cent; P = 0.844). One patient in group 1 (2 per cent) and two in group 2 (2 per cent) had developed thrombosis of major intrahepatic blood vessels on follow-up computed tomography scan. There were no significant differences between groups 1 and 2 in mortality rate (2 versus 0 per cent; P = 0.366), complete ablation rate for small HCC (92 versus 98 per cent; P = 0.197), local recurrence rate (11 versus 9 per cent; P = 0.762) and overall survival (1-year: 86 versus 87 per cent; 2-year: 75 versus 75 per cent; P = 0.741). CONCLUSION: RFA without hepatic inflow occlusion is a safe and effective treatment for perivascular HCC.     

输血对大肝癌切除术后近远期预后的影响

目的研究输血对大肝癌切除术后近期并发症和远期存活率的影响。方法回顾性分析177例大肝癌切除术病例，结合随访分析输血对近期并发症和远期存活率的影响。结果本组大肝癌围手术期输血率为74．6％。近5年输血量及输血率较5年前显著减少（P〈0．01）。不输血组并发症率低于输血组（P〈0．05）。单因素分析显示，年龄、肝门阻断、术中出血量、输血量以及手术时间与术后并发症发生有关。多因素分析显示，年龄、肝门阻断、输血量以及手术时间是决定术后并发症的4个独立的预测指标。本组大肝癌1、3、5年总存活率为67％、44％和34％，1、3、5年无瘤存活率为51％、31％和31％。不输血组和输血组的总存活率以及无瘤存活率无显著差别。结论输血是决定大肝癌切除术后并发症发生的独立危险因素之一，但输血对大肝癌切除术后存活率无显著影响。肝脏外科医生应积极采取各种方法尽可能避免大肝癌切除术围手术期的输血。     

Laparoscopic liver resection

BACKGROUND: This paper describes a 10-year experience of laparoscopic liver surgery, including several major hepatectomies for malignant tumours. METHODS: Of 243 hepatectomies carried out between January 1995 and December 2004, 113 (46.5 per cent) were performed by laparoscopy and 89 were included in this retrospective study. RESULTS: Twenty-four laparoscopic hepatectomies (27 per cent) were for benign disease and 65 (73 per cent) for malignant tumours, including hepatocellular carcinoma (HCC) in 16 patients and colorectal metastasis (CRM) in 41. Minor hepatectomy was performed in 51 patients and major hepatectomy (three or more Couinaud segments) in 38. Conversion to laparotomy was necessary in 12 patients and perioperative blood transfusion in eight. One patient with cirrhosis who underwent right hepatectomy for HCC with conversion to open surgery died 8 days after surgery. Major morbidity occurred in eight patients (16 per cent) having minor hepatectomy and in 11 (29 per cent) of those having a major resection. The 3-year overall and disease-free survival rates for patients with CRM (mean follow-up 30 months) were 87 (11 patients at risk) and 51 (6 patients at risk) per cent respectively. Corresponding values for patients with HCC (mean follow-up 40 months) were 85 (10 patients at risk) and 68 (5 patients at risk) per cent. CONCLUSION: In experienced hands, the results of laparoscopic liver surgery are similar to those for laparotomy.

French multicentre prospective observational study of laparoscopic versus open colectomy for sigmoid diverticular disease

BACKGROUND: The aim of this study was to compare in-hospital morbidity and mortality rates after elective laparoscopic and open colorectal surgery for sigmoid diverticular disease (SDD). METHODS: This prospective national multicentre observational study included all consecutive patients undergoing open or laparoscopic elective colectomy for SDD in a 4-month period between June and September 2002. Postoperative in-hospital mortality and morbidity in the two groups were compared. RESULTS: Three hundred and thirty-two consecutive patients undergoing either laparoscopic (163 patients) or open (169 patients) colectomy for SDD were analysed. Overall postoperative mortality and morbidity rates were 0.3 and 23.8 per cent respectively. The morbidity rate was significantly higher in the open than in the laparoscopic group (P < 0.001), leading to a significantly longer hospital stay (P < 0.001). The morbidity rate remained significantly higher in the open group when the patients were matched for age (P = 0.015) or American Society of Anesthesiologists score (P = 0.028). An open procedure (relative risk (RR) 2.13 (95 per cent confidence interval (c.i.) 1.29 to 3.45)), age over 70 years (RR 1.62 (95 per cent c.i. 1.14 to 2.30)) and intraperitoneal contamination (RR 2.54 (95 per cent c.i. 1.18 to 5.50)) were identified as independent risk factors for morbidity. CONCLUSION: A laparoscopic approach to elective treatment of SDD may be associated with reduced postoperative morbidity and hospital stay. A randomized study is required to confirm these results.     

Liver resection for hepatocellular carcinoma in patients with cirrhosis

BACKGROUND: Although liver resection is now a safe procedure, its role for hepatocellular carcinoma (HCC) in patients with cirrhosis remains controversial. METHODS: This study compared the results of liver resection for HCC in patients with cirrhosis over two time intervals. One hundred and sixty-one patients had resection during period 1 (1991-1996) and 265 in period 2 (1997-2002). Early and long-term results after liver resection in the two periods were compared, and clinicopathological characteristics that influenced survival were identified. RESULTS: Tumour size was smaller, indocyanine green retention rate was higher, patients were older and a greater proportion of patients were asymptomatic in period 2 than period 1. Operative blood loss, need for blood transfusion, operative mortality rate, postoperative hospital stay and total hospital costs were significantly reduced in period 2. The 5-year disease-free survival rates were 28.2 and 33.9 per cent in periods 1 and 2 respectively (P = 0.042), and 5-year overall survival rates were 45.9 and 61.2 per cent (P < 0.001). Multivariate analysis identified serum alpha-fetoprotein level, need for blood transfusion and Union Internacional Contra la Cancrum tumour node metastasis stage as independent determinants of disease-free and overall survival. CONCLUSION: The results of liver resection for HCC in patients with cirrhosis improved over time. Liver resection remains a good treatment option in selected patients with HCC arising from a cirrhotic liver.     

Prognostic factors and survival after hepatic resection for hepatocellular carcinoma without cirrhosis

BACKGROUND: Detailed follow-up of patients with chronic hepatitis has resulted in increased diagnosis of hepatocellular carcinoma (HCC) in patients without cirrhosis. Despite numerous studies on hepatic resection, the prognostic factors for intrahepatic recurrence and survival are not well known for patients with HCC without cirrhosis. METHODS: Among 349 patients with HCC treated in the past 13 years, cirrhosis was absent in 126 patients (36 per cent). Curative hepatic resection was carried out in 100 (79 per cent) of these patients. Risk factors for intrahepatic recurrence and prognostic factors for survival were evaluated by univariate and multivariate analyses. RESULTS: Postoperative morbidity and mortality rates were 22 and 3 per cent respectively. The 5- and 10-year disease-free and overall survival rates were 31 and 50 per cent, and 22 and 47 per cent respectively. Blood loss, surgical resection margin, intrahepatic metastasis, portal vein invasion and extent of hepatic resection were independently associated with overall survival. However, the only risk factors for intrahepatic recurrence were portal vein invasion and hepatitis C virus (HCV) infection. The former was related to early recurrence while the latter was related to later recurrence. The 5-year disease-free survival rate was 58 per cent in patients with hepatitis B virus infection while it was 6 per cent in patients with HCV infection (P < 0.001). CONCLUSION: In the treatment of HCC without cirrhosis, major hepatectomy is advocated to prevent early recurrence. Liver transplantation may be required for patients with HCV infection.     

Repeat hepatic resection for recurrent colorectal liver metastases is associated with favourable long-term survival

BACKGROUND: The management of patients with recurrent colorectal liver metastases (RCLM) remains controversial. This study aimed to determine whether repeat liver resection for RCLM could be performed with acceptable morbidity, mortality and long-term survival. METHODS: Of 1121 consecutive liver resections performed and prospectively analysed between 1987 and 2005, 852 'curative' resections were performed on patients with colorectal liver metastases. Single liver resection was performed in 718 patients, and 71 repeat hepatic resections for RCLM were performed in 66 patients. RESULTS: There were no postoperative deaths following repeat hepatic resection compared with a postoperative mortality rate of 1.4 per cent after single hepatic resection. Postoperative morbidity was comparable following single and repeat hepatectomy (26.1 versus 18 per cent; P = 0.172), although median blood loss was greater during repeat resection (450 versus 350 ml; P = 0.006). Actuarial 1-, 3- and 5-year survival rates were 94, 68 and 44 per cent after repeat hepatic resection for RCLM, compared with 89.3, 51.7 and 29.5 per cent respectively following single hepatectomy. CONCLUSION: The beneficial outcomes observed after repeat liver resection in selected patients with RCLM confirm the experience of others and support its status as the preferred choice of treatment for such patients.     

Validation of POSSUM scoring systems for audit of major hepatectomy

BACKGROUND: The aim of the study was to validate the use of Physiological and Operative Severity Score in the enUmeration of Mortality and morbidity (POSSUM) and Portsmouth (P) POSSUM scoring systems to predict postoperative mortality in a group of Chinese patients who had a major hepatectomy for hepatocellular carcinoma. METHODS: A retrospective analysis was performed on data collected prospectively over a 6-year interval from January 1997 to December 2002. The mortality risks were calculated using both the POSSUM and the P-POSSUM equations. RESULTS: Two hundred and fifty-nine patients underwent major hepatectomy; there were 17 (6.6 per cent) postoperative deaths. Of 32 preoperative and intraoperative variables studied, age, smoking habit, serum creatinine concentration, American Society of Anesthesiologists grade, and physiological and operative severity scores were found to be significant factors predicting mortality. On multivariate analysis only the physiological and operative severity scores were independent variables. The POSSUM system overpredicted mortality risk (14.2 per cent) and there was a significant lack of fit in these patients (chi(2) = 14.1, 3 d.f., P = 0.003). The mortality rate predicted by P-POSSUM was 4.2 per cent and showed no significant lack of fit (chi(2) = 7.6, 3 d.f., P = 0.055), indicating that it predicted outcome effectively. A new logistic equation was derived from the present patient data set that requires testing prospectively. CONCLUSION: P-POSSUM significantly predicted outcome in Chinese patients who had major hepatectomy for hepatocellular carcinoma. A modified disease-specific equation requires further testing.     

Reduction of postoperative morbidity and mortality in patients with rectal cancer following the introduction of a colorectal unit

BACKGROUND: Surgery for rectal cancer is associated with high morbidity and mortality rates. The reason for this has been much debated. This population-based study reports the findings on postoperative morbidity and mortality after rectal cancer surgery following the introduction of a centralized colorectal unit in a county central hospital, supervised by a colorectal surgeon using the most recent techniques. METHODS: All consecutive patients with rectal cancer who underwent surgery at four county hospitals in the V?stmanland county in Sweden during 1993-1996 (n = 133) were compared with patients who underwent surgery at the new colorectal unit in the county central hospital from 1996 to 1999 (n = 144). RESULTS: The number of operating surgeons was reduced from 26 to four. The postoperative mortality rate decreased from 8 to 1 per cent (P = 0.002) and the total postoperative complication rate was reduced from 57 to 24 per cent (P < 0.001). Surgical complications dropped from 37 to 11 per cent (P < 0.001). The relaparotomy rate fell from 11 to 4 per cent (P < 0.05). Postoperative stay in hospital was reduced from a median of 13 to 9 days (P < 0.001). CONCLUSION: The new organization, with centralized rectal cancer surgery using modern techniques, reduced postoperative mortality and overall morbidity rates to less than half.     

Salvage hepatic resection after incomplete interstitial therapy for primary and secondary liver tumours

BACKGROUND: When the response to percutaneous ablation therapy (PAT) of liver tumours is incomplete, surgery may be undertaken as a salvage therapy. To validate the safety and effectiveness of salvage hepatectomy, patients who had undergone PAT or no treatment before hepatectomy were compared. METHODS: Of 137 patients who had hepatectomy for primary and secondary tumours, 21 had undergone PAT and 116 had surgery as primary treatment. Tumour features and the incidence of liver cirrhosis were similar in the two groups. RESULTS: Peroperative mortality and major morbidity rates were zero and 5 per cent (one of 21) respectively among patients who had PAT before surgery, and 0.9 per cent (one of 116) and zero in those who did not. Duration of operation (mean 495 versus 336 min; P<0.001), clamping time (mean 81 versus 53 min; P<0.001), blood loss (mean 519 versus 286 ml; P=0.004), need for blood transfusion (six of 21 patients versus nine of 116; P=0.001), and rates of thoracophrenolaparotomy (eight of 21 versus 14 of 116; P<0.001) and resection of other tissues (six of 21 versus nine of 116; P<0.001) were significantly higher in the PAT group. CONCLUSION: Hepatectomy after incomplete PAT is safe and effective, but more extensive procedures are necessary. The effect of salvage hepatectomy on long-term outcome is still unclear.     

Extensive surgery for carcinoma of the gallbladder

BACKGROUND: The purpose of this study was to clarify the efficacy of, and define the indications for, extensive surgery for gallbladder carcinoma. METHODS: Between 1979 and 1994, 116 patients with gallbladder carcinoma underwent operation. Radical resection was performed in 80 patients. RESULTS: In 68 patients with stage III or IV disease, extensive resection including extended right hepatectomy (n = 40), pancreaticoduodenectomy (n = 23) and/or portal vein resection (n = 23) was employed to achieve complete tumour excision. The hospital mortality rate was 18 per cent. The postoperative 3- and 5-year survival rates were 44 and 33 per cent respectively in the patients with stage III disease (n = 9), and 24 and 17 per cent respectively in patients with stage IV (M0) disease (n = 29). In contrast, the postoperative survival rate for the 30 patients with stage IV (M1) disease (7 per cent at 3 years and 3 per cent at 5 years) was worse than that for patients with stage III and stage IV (M0) disease (P = 0.009 and P = 0.062 respectively). CONCLUSION: Radical resection should be undertaken for stage III and stage IV (M0) gallbladder cancer. Although portal vein resection and/or pancreaticoduodenectomy did not contribute to long-term survival, better survival was obtained than that for the unresected patients.     

Trends in morbidity and mortality after hepatic resection for hepatocellular carcinoma: an institute's experience with 625 patients

BACKGROUND: Despite recent developments in surgery and patient management during the perioperative period, critical complications still developed in a few patients who had hepatic resection for hepatocellular carcinoma (HCC). STUDY DESIGN: Six hundred twenty-five consecutive patients who had hepatic resection for HCC were reviewed and operative morbidity and mortality rates assessed. RESULTS: There were progressive decreases in the surgical blood loss and the rate of blood transfusion (p = 0.0001). Occurrence of ascites and other complications dramatically decreased in the study series (p = 0.0001). Hospital death rate and incidence of postoperative liver failure also decreased from 2.5%, 1.9% (1985 to 1990), 4.4%, 3.2% (1991 to 1996) to 1.9%, 1.4% (1997 to 2002), respectively. Using multiple logistic regression, independent risk factors associated with postoperative complications were found to be the period of operation (odds ratio [OR] = 0.408; p < 0.0001) and alanine aminotransferase > or = 70 IU/L (OR = 2.020; p = 0.0009) over the entire period of this study (1985 to 2002), or the platelet count of < 100 x 10(3)/mm(3) (OR = 4.654; p = 0.0072) and the presence of blood transfusion during operation (OR = 8.249; p = 0.0230) in 1997 to 2002. CONCLUSIONS: In this series, there has been a decline in surgical blood loss and rate of blood transfusion and in the number of patients with major complications. These results are largely attributable to the adequate selection of surgical candidate and factors aimed at reducing surgical blood loss.
