上世纪60年代,肝切除手术的死亡率高达30%~40%,死亡的主要原因是大出血。近20年来,随着人们对肝脏解剖认识的加深、影像学技术的发展、手术技术水平的不断提高以及围手术期处理的进步,肝切除术中大出血的发生率已明显下降。在不少作者近几年报告的病例中,约有50%左右的病例术中及围手术期可以不需要输血。尽管如此,由于术中大出血所导致的肝切除手术失败的病例仍时有发生。肝切除术中出血量仍然是决定手术成功与否的关键。控制术中出血的技术也是肝切除术中最关键的技术。物理止血是减少术中肝切缘出血的有效技术。高频电凝止血的原理是高频… 相似文献

随着肝脏外科技术的发展,围手术期管理和患者筛选标准的进步使可以接受半肝切除术或扩大肝切除术的患者数量大大增加.而肝切除术后肝功能衰竭是肝切除术后严重的并发症之一,肝切除术后肝功能衰竭患者相关风险中糖尿病及已有肝脏疾病如肝硬化、脂肪肝、胆汁淤积等是最重要的危险因素.手术相关风险中残肝体积及术中大出血是影响肝切除术后肝功能衰竭发病率及病死率的关键因素.而到目前为止还没有很好的方法治疗肝功能衰竭,所以预防显得尤为重要. 相似文献

Major hepatectomy for hepatocellular carcinoma in patients with an unsatisfactory indocyanine green clearance test. 总被引:10,自引:0,他引:10
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. 相似文献

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. 相似文献

Hepatectomy for hepatocellular carcinoma: the surgeon's role in long-term survival. 总被引:10,自引:0,他引:10

HYPOTHESIS: The surgeon can contribute substantially to the long-term survival rate of patients undergoing hepatectomy for hepatocellular carcinoma (HCC). DESIGN: The long-term survival rate of patients with HCC undergoing hepatectomy has improved, but the contribution of the surgeon to the improved survival rate is unknown. We surveyed 211 consecutive patients undergoing hepatectomy for HCC. The clinical, operative, and pathological factors were analyzed to identify factors that were important in affecting long-term survival. SETTING: A tertiary referral center. PATIENTS: From April 1989 to December 1995, 211 consecutive patients with HCC underwent 153 major and 58 minor hepatectomies. MAIN OUTCOME MEASURES: Disease-free and overall cumulative survival rate. RESULTS: The 5-year disease-free survival rate was 27%. By Cox regression analysis, blood transfusion (relative risk [RR], 1.21; 95% confidence interval [CI], 1.05-1.40) and TNM stage (RR, 1.90; 95% CI, 1.47-2.47) were shown to be independent prognostic factors in the 5-year disease-free survival rate. The 5-year overall cumulative survival rate was 37%. By Cox regression analysis, the preoperative indocyanine green retention value at 15 minutes after injection (RR, 1.03; 95% CI, 1.01-1.06), blood transfusion (RR, 1.191; 95% CI, 1.078-1.316), tumor rupture (RR, 1.48; 95% CI, 1.08-2.04), and TNM stage (RR, 1.62; 95% CI, 1.27-2.07) were shown to be significant independent factors that influenced cumulative survival rate. CONCLUSIONS: The long-term survival of patients with HCC after hepatectomy depends on tumor staging, preoperative hepatic functional reserve, history of blood transfusion, and rupture of HCC. Preoperative liver function and tumor staging cannot be altered; however, the surgeon can play an important role in improving the prognosis if blood transfusion and iatrogenic tumor rupture can be avoided and if function of the liver remnant can be preserved. 相似文献

Risk factors for perioperative morbidity and mortality after extended hepatectomy for hepatocellular carcinoma 总被引:16,自引:0,他引:16
BACKGROUND: Extended hepatectomy with resection of more than four segments is a high-risk operation, especially in patients with hepatocellular carcinoma (HCC) associated with chronic liver disease. This study evaluated the risk factors for morbidity and mortality following extended hepatectomy for HCC. METHODS: Preoperative and intraoperative variables of 155 patients who underwent extended hepatectomy for HCC were analysed to identify risk factors for postoperative morbidity and mortality. RESULTS: The overall morbidity rate was 55.5 per cent (n = 86). Most morbidity was due to ascites or pleural effusion. Significant life-threatening complications occurred in 20.0 per cent (n = 31). The perioperative mortality rate was 8.4 per cent (n = 13). Multivariate analysis found that portal clamping (P = 0.023) and perioperative blood transfusion (P < 0.001) were risk factors for morbidity, whereas perioperative blood transfusion (P < 0.001) was the only risk factor for significant morbidity. Co-morbid illness (P = 0.019) and perioperative blood transfusion (P = 0.004) were risk factors for perioperative mortality. CONCLUSION: Meticulous operative techniques to minimize blood loss and transfusion, while avoiding a prolonged Pringle manoeuvre, may help reduce postoperative morbidity. Avoidance of perioperative blood transfusion and careful preoperative selection of patients in terms of overall physiological status are important measures to reduce the postoperative mortality rate. 相似文献

Objective: To deWne the safety of major hepatectomy for hepatocellular carcinoma (HCC) associated with cirrhosis and the selection criteria for surgery in terms of hospital mortality.
Design: Major hepatectomy for HCC in the presence of cirrhosis is considered to be contraindicated by many surgeons because the reported mortality rate is high (26% to 50%). Previous workers recommended that only selected patients with Child''s A status or indocyanine green (ICG) retention at 15 minutes of less than 10% undergo major hepatectomy. A survery was made, therefore, of our patients with HCC and cirrhosis undergoing major hepatectomy between 1989 and 1994.
Setting: A tertiary referral center.
Patients: The preoperative, intraoperative, and post-operative data of 54 patients with cirrhosis who had major hepatectomy were compared with those of 25 patients with underlying chronic active hepatitis and 22 patients with normal livers undergoing major hepatectomy for HCC. The data had been prospectively collected.
Intervention: Major hepatectomy, defined as resection of two or more liver segments by Goldsmith and Woodburn nomenclature, was performed on all the patients. Main Outcome Measure: Hospital mortality, which was defined as death within the same hospital admission for the hepatectomy.
Results: Preoperative liver function in patients with cirrhosis was worse than in those with normal livers. The intraoperative blood loss was also higher (P=.01), but for patients with cirrhosis, chronic active hepatitis, and normal livers, the hospital mortality rates (13%, 16%, and 14%, respectively) were similar. The hospital mortality rate for patients with cirrhosis in the last 2 years of the study was only 5%. Patients with cirrhosis could tolerate up to 10 L of blood loss and survive the major hepatectomy. By discriminant analysis, an ICG retention of 14% at 15 minutes was cutoff level that could maximally separate the patients with cirrhosis with and without mortality.
Conclusion: Major hepatectomy for HCC in the presence of cirrhosis is associated with a mortality rate that is not different from the rate for patients with normal livers. An ICG retention of 14% at 15 minutes would serve as a better selection criterion than the 10% previously used. 相似文献

One hundred consecutive hepatobiliary resections for biliary hilar malignancy: preoperative blood donation, blood loss, transfusion, and outcome 总被引:10,自引:0,他引:10
BACKGROUND: Many reports on blood loss and transfusion requirements during hepatectomy for metastatic liver cancer or hepatocellular carcinoma have been published; however, there are no reports on these issues in hepatectomy for biliary hilar malignancy. The aim of this study was to review our experience with blood loss and perioperative blood requirements in 100 consecutive hepatectomies for biliary hilar malignancy. METHODS: One hundred consecutive hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for hilar malignancies were performed, including 81 perihilar cholangiocarcinomas and 19 advanced gallbladder carcinomas involving the hepatic hilus. Fifty-eight hilar resections were combined with other organ and/or vascular resection. Data on preoperative blood donation, intraoperative blood loss, and perioperative transfusion were collected and analyzed. RESULTS: Preoperative autologous blood donation was possible in 73 patients (3.4 +/- 1.2 U). Intraoperative blood loss was 1850 +/- 1000 mL (range, 677-5900 mL), and it was < 2000 mL in 62 patients. Intraoperatively, only 7 of the 73 patients (10%) who donated blood received transfusion of unheated, homologous blood products (packed red blood cells or fresh frozen plasma), whereas 18 the 23 patients (67%) without donation received homologous transfusions. Only 16 patients received transfusion postoperatively, and overall, 35 patients received unheated homologous blood products. Total serum bilirubin concentrations after hepatectomy in patients receiving autologous blood transfusion only was similar to those in patients who did not receive transfusion. The incidence of postoperative complications was higher in the 35 patients who received perioperative homologous transfusion than in 65 patients who did not (94% vs 52%; P <.0001). The mortality rate (including all deaths) was 3% (myocardial infarction, intra-abdominal bleeding, and liver failure, 1 patient each). CONCLUSIONS: Despite the technical difficulties arising from hepatectomy for biliary hilar malignancy, approximately two thirds of hepatectomies can be performed in an experienced center without perioperative homologous blood transfusion using preoperative blood donation. 相似文献
