??Objective:To study the factors associated with postoperative complications of resection of hepatocellular carcinoma. Methods:Consecutive 378 cases of hepatocellular carcinoma between June 1988 and April 2005 at Xiangya Hospital were summarized retrospectively.Single??variant and multivariate stepwise regression model were used to analysis the factors associated with postoperative complications of resection of hepatocellular carcinoma. Results:The overall morbidity rate and mortality rate were 17.7% and 1.3% respectively.Single??variant analysis showed that the age,pringle maneuver,intraoperative blood loss and blood transfusion were associated with postoperative complications.Furthermore,multivariate stepwise regression analysis revealed that the age,pringle maneuver,intraoperative blood loss and blood transfusion volume were the independent risk factors of morbidity rate of resections of hepatocellular carcinoma. Conclusion:The surgical excisions of hepatocellular carcinomas are safe and feasible only if the liver function reserve could be judged accurately before operation and the intraoperative hemorrhage and blood transfusion could be controlled effectively and the duration of portal clamping could be shortened during the operation. 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: 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

OBJECTIVE: To evaluate the feasibility, safety, efficacy, amount of hemorrhage, postoperative complications, and ischemic injury of selective clamping in patients undergoing minor liver resections. SUMMARY BACKGROUND DATA: Inflow occlusion can reduce blood loss during hepatectomy. However, Pringle maneuver produces ischemic injury to the remaining liver. Selective hemihepatic vascular occlusion technique can reduce the severity of visceral congestion and total liver ischemia. PATIENTS AND METHODS: Eighty patients undergoing minor hepatic resection were randomly assigned to complete clamping (CC) or selective clamping (SC). Hemodynamic parameters, including portal pressure and the hepatic venous pressure gradient (HVPG), were evaluated. The amount of blood loss, measurements of liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), and postoperative evolution were also recorded. RESULTS: No differences were observed in the amount of hemorrhage (671 +/- 533 mL versus 735 +/- 397 mL; P = 0.54) or the patients that required transfusion (10% versus 15%; P = 0.55). There were no differences on postoperative morbidity between groups (38% versus 29%; P = 0.38). Cirrhotic patients with CC had significantly higher ALT (7.7 +/- 4.6 versus 4.5 +/- 2.7 mukat/L, P = 0.01) and AST (10.2 +/- 8.7 versus 4.9 +/- 2.1 mukat/L; P = 0.03) values on the first postoperative day than SC. The multivariate analysis demonstrated that high central venous pressure, HVPG >10 mm Hg, and intraoperative blood loss were independent factors related to morbidity. CONCLUSIONS: Both techniques of clamping are equally effective and feasible for patients with normal liver and undergoing minor hepatectomies. However, in cirrhotic patients selective clamping induces less ischemic injury and should be recommended. Finally, even for minor hepatic resections, central venous pressure, HVPG, and intraoperative blood loss are factors related to morbidity and should be considered. 相似文献
