【摘要】目的探讨提高可切除胰头癌疗效和降低手术风险的方法。方法回顾我院1996年1月至2001年12月期间行根治性胰十二指肠切除术治疗的胰头癌病例，对可切除胰头癌患者的术前评估、围手术期治疗和术式选择进行分析。结果外科收治胰头癌271例，行根治性切除术73例，根治切除率为26.9%（73/271），围手术期死亡率为6.8%（5/73）。其中56例行改良扩大的胰十二指肠切除术，1年和3年生存率分别为71.4%和33.9%。结论根治性胰十二指肠切除术是可切除胰头癌惟一可能提供治愈机会的治疗选择。加强术前评估并同时重视围手术期处理，有助于改善预后。
Objective To discuss the therapeutic effectiveness of surgical approach to complex intrahepatolithiasis with biliary liver cirrhosis.Methods A case of complex intrahepatolithiasis with biliary liver cirrohosis, portal hypertension was treated with splenectomy and pericardial devascularization plus left hepatectomy and portal cholangio plasty with T tube drainage. Results Follow up one year and a half after operation, no symptom of cholangitis was found, and there is no relapse up to date. Conclusion Combined operation of hepatectomy with splenectomy is an ideal and effective treatment for complex intrahepatolithiasis with biliary liver cirrhosis.

ObjectiveTo explore the curative effect of synchronous resection of hepatopancreas lesions in the treatment of hepatic oligometastatic pancreatic cancer. MethodsThe patients with hepatic oligometastatic pancreatic cancer who met the inclusion and exclusion criteria in the Neijiang Second People’s Hospital from January 2016 to December 2020 were retrospectively collected. The enrolled patients were divided into resection group and non-resection group according to the treatment method. The patients in the resection group were treated with synchronous resection of hepatopancreas lesions, the patients in the non-resection group were treated with conservative treatment including palliative bypass surgery, biliary drainage, systemic chemotherapy, and so on. The patients were followed up to December 2021. The overall survival of the patients in the two groups were compared, and the factors affecting the overall survival were analyzed. ResultsA total of 54 patients who met the inclusion and exclusion criteria were collected in this study, including 31 cases in the resection group and 23 cases in the non-resection group. There were no statistical differences between the two groups in the baseline data such as age, gender, preoperative liver function indexes, and so on (P>0.05). The pancreaticojejunostomy leakage occurred in 7 cases (22.6%) of the resection group. The median follow-up time of the resection group and the non-resection group were 14 and 11 months. The median overall survival time of patients in the resection group and non-resection group were 18.0 months [95%CI (13.8, 22.1)] and 12.0 months [95%CI (8.2, 15.8)] respectively. The survival of the resection group was better than that of the non-resection group by log-rank test (χ2=4.074, P=0.045). Cox multivariate regression analysis result showed that the preoperative low albumin level (≤35.0 g/L), no perioperative chemotherapy, and no synchronous resection of hepatopancreas lesions shortened the overall survival time of patients with hepatic oligometastatic pancreatic cancer (P<0.05). For the patients who underwent the synchronous resection of hepatopancreas lesions, R0 resection and perioperative chemotherapy could prolong the overall survival time (P<0.05). ConclusionsFrom the results of this study, synchronous resection of hepatopancreas lesions can benefit survival for patients with hepatic oligometastatic pancreatic cancer. The prognosis of patients without R0 resection and perioperative chemotherapy is even worse.
Objective To study the expression and significance of multidrug resistance-associated protein (MRP) gene in hepatocellular carcinoma (HCC). Methods Reverse transcription polymerase chain reaction (RT-PCR) assay was used to detect the expression of MRP mRNA in 25 fresh specimens of the primary HCC and its surrounding liver tissues. Immunohistochemistry LSAB technique was adopted to test MRP in 60 HCC specimens. The drug sensitivity was also tested by flow cytometry.Results The positive expression rates of MRP mRNA and MRP protein in primary HCC were 44.00%(11/25) and 45.00%(27/60) respectively. All the intensity of expression was low, but significant higer than its surrouding liver tissues (P＜0.05). The intensity and expression rate of MRP protein in 5 recurrent HCC had a tendency to increase. There was a correlation between the expression of MRP mRNA and MRP protein in 25 patients using RT-PCR and immunohistochemistry assay (Plt;0.05). Detected by flow cytometry, the average sensitivity of drugs in vitro of 60 HCC sp-cimens were 5-FU （15.80±7.63）%，DDP（18.45±9.59）%，ADM（17.95±7.99）%，MMC（16.60±8.69）% and CTX（17.40±10.14）%. Only 5FU and ADM were significantly affected by the expression of MRP protein (Plt;0.05).Conclusion The expression of MRP in primary HCC may be one of the important mechanisms of the intrinsic and acquired drug resistance in HCC. To study the expression of MRP could give a predictive value in HCC chemotherapy.

【Abstract】ObjectiveTo investigate the perioperative management in hepatectomy using hepatic energy metabolisom for enhancing safety of and improving the survival in patients with primary liver cancer (PLC).MethodsTwo thousands and one hundred fortythree patients with PLC were treated in this hospital from January 1990 to January 2004. The perioperative data, operative approach, postoperative treatment, postoperative clinical course and follow up data were retrospectively analyzed. All patients were divided into two groups: the early period group and the late period group(from January 1997 to January 2004) and comparison was taken between two groups. The preoperative redox tolerance index (RTI), intraoperative hepatopetal blood occlusion of half liver, and postoperative arterial ketone body ratio (AKBR) were investigated and evaluated.Results①The proportion of small PLC and resection rate increased, the morbidity of complications and mortality after hepatectomy decreased, also the survival rate prolonged in the late period group. ②When using RTI as an indicator for selection of hepatectomy, the morbidity of complications decreased from 21.1% to 11.0%, the mortality form 1.6% to 0.3%. ③Comparising hepatopetal blood occlusion of total liver (n=476) with half liver (n=523),the postoperative morbidity of complications and mortality were 25.8% to 11.9% and 2.3% to 0.6% respectively. ④Postoperative AKBR measurements was a reliable indicator to assess the energy status of the liver and liver failure.ConclusionRTI is of potential value in predicting preoperative hepatic functional reserve, hepatopetal blood occlusion of half liver could protect the residual liver function, and postoperative AKBR measuremeant is a simple and accurate means of determining the immediate state of metabolic dysfunctioning in liver resection. The authors propose that perioperative treatment is an important factor in decreasing operative complications and mortality rate after liver resection.
