目的:探讨肝胆管结石合并胆管癌的临床表现特征和诊治经验。方法:分析了自2001年1月到2009年8月我院收治的30例肝胆管结石合并胆管癌患者的临床资料。结果:肝胆管结石合并胆管癌术前确诊10例,术中病理检查确诊14例,术后病理检查发现6例。左肝胆管癌16例,占533%,右肝胆管癌7例占233%,肝门部胆管癌5例占167%,其余2例为左右肝都有。肿瘤根治性切除术17例(567%),姑息性手术9例(30%),单纯活检4例(133%)。在30例随访资料中,根治性切除术者平均存活时间26个月。存活1年以上10例,2年以上5例,3年以上2例;姑息治疗者术后平均生存9个月;其余的≤4个月。结论:胆石症状易反复发作,胆道病史较长大于10年且术前CA199gt;2500 ng/mL的患者应高度怀疑合并有胆管癌。
目的:探讨Livin基因在人胆管癌组织及胆管癌细胞系中的表达情况及其与胆管癌发 生发展之间的关系。方法:采用免疫组织化学技术（SP法）检测Livin基因蛋白在45例人胆管 癌标本及及40例癌旁胆管组织、20例正常胆管组织标本中的表达；同时采用RTPCR法及SP 法检测了Livin基因mRNA和蛋白在人胆管癌细胞系QBC939及非肿瘤细胞系HT1080中表达。 结果:Livin在胆管癌组织中表达阳性率为57.8%，而癌旁胆管组织、非癌胆管组织中未能检 测到Livin表达。Livin表达与性别、年龄、肿瘤大小及肿瘤分化程度无关。在有淋巴结转组 中，Livin阳性表达率（70.4%）明显高于无淋巴结转移组（38.9%）。在人胆管癌细胞QBC939 中，Livin mRNA及蛋白均特异性表达，而非肿瘤细胞系HT1080未见Livin表达。结论:Livin 基因在人类胆管癌组织和细胞系中选择性高表达，其可能与胆管癌发生、发展及预后密切相 关。
目的:总结肝部分切除治疗肝胆管结石的临床经验。方法:回顾性分析91例肝胆管结石的定位诊断、手术方式、临床效果和手术并发症等情况。结果:术前行彩超检查91例（100％）、CT检查78例（85.7％）、MRI检查6例（5.5％）。术中发现合并胆管狭窄24例（26.4％），合并胆管癌2例（2.1％）。左外叶或左半肝切除71例（78.0％）、右叶各段切除18例（19.8％）、右半肝切除2例（2.2％）。术后并发症发生率19.8％，残石率18.7％。结论:彩超+CT对肝胆管结石的术前定位诊断基本能满足术前对手术方式的制定；以肝段叶切除为主的综合治疗方案是治疗肝胆管结石的有效手段；术中、术后彩超、纤维胆道镜的运用及术后针对患者具体情况的对症治疗措施可提高临床效果，减少并发症。
目的:探讨腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）致胆管损伤的原因、预防措施和经验教训。方法:分析2007年8月～2008年8月期间我院胆道外科收治的3例胆管严重损伤病例资料。结果:3例LC术致胆管严重损伤的患者均发生肝门部胆管狭窄，并均在肝门胆管成形后行胆管空肠Roux-en-Y吻合术，吻合口直径2.0～3.0 cm。术后患者恢复良好，均顺利出院，住院时间为10～15天。随访1～6个月，1例于术后2月出现肝区隐痛，口服消炎药可控制，其余未见异常不适。结论:术中仔细辩清肝总管、胆总管与胆囊管的三者关系是预防LC术胆管损伤的关键。胆管空肠Roux-en-Y吻合术是处理胆管损伤的重要手术方式。LC术时，胆道外科医生思想上要高度重视，不可盲目追求速度。
目的 探讨内镜下治疗胆管乳头状瘤的价值。方法 6例经病理学检查证实的胆管乳头状瘤患者在行“胆道探查+ T管引流术”后6～8周行胆道镜下高频电刀烧灼术，对术后治疗效果进行评估。结果 6例患者术后胆汁引流量逐渐增多至100～400 ml/d(平均250 ml/d)，胆汁黏稠度明显减轻，黄疸减退。术后随访1～3年，平均2年，3例患者术后黄疸、腹痛明显减轻，至今无复发； 2例在继续治疗中； 1例患者随访半年，T管引流通畅，但因严重肺部感染并发多器官功能衰竭死亡。结论 内镜下高频电刀烧灼治疗胆管乳头状瘤能有效缓解患者的临床症状，明显提高患者的生存质量。
Objective To explore primary surgical treatment experience of typeⅣ hilar cholangiocarcinoma. Methods From April 2008 to April 2011，20 patients with type Ⅳ hilar cholangiocarcinoma were enrolled into the same surgical group in Department of Hepatobiliary and Pancreatic Surgery of West China Hospital of Sichuan University.The intra- and post-operative results were analyzed.Results The total resection rate was 75%，which was consisted of 10 cases of radical excision and 5 cases of non-radical excision.Seven patients received left hepatic trisegmentectomy and caudate lobe resection including anterior and posterior right hepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy.Six patients received enlarged left hepatic trisegmentectomy and caudate lobe resection including left intrahepatic and extrahepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy. Two patients received quadrate lobe resection including two cholangioenterostomies after anterior and posterior right hepatic duct reconstruction，and left intrahepatic and extrahepatic duct reconstruction.After percutaneous transhepatic cholangial drainage （PTCD） and portal vein embolization （PVE），two patients with total bilirubins ＞400 mmol/L received radical excision and non-radical excision，respectively.Three patients only received PTCD during operation due to wide liver and distant metastasis，and two patients received T tube drainage during operation and postoperative PTCD due to left and right portal vein involvement. All 15 patients who received lesion resection survived more than one year， whereas another five patients whose lesions can not been resec ted only survived from 3 to 6 months with the mean of 4.2 months.No death occurred during the perioperative period. Conclusions For patients with type Ⅳ hilar cholangiocarcinoma， preoperative evaluation and tumor resection shall conducted so as to relieve obstruction of biliary tract，otherwise PTCD and PVE prior to the final lesion resection shall be performed.
ObjectiveTo explore the expressions of prostaglandin F2α receptor (PTGFR) and cyclooxygenase-2 (COX-2) in tissues of benign bile duct scar and their significances, and investigate the regulating effect of transforming growth factor-β1 (TGF-β1) on the expression of PTGFR in human bile duct fibroblasts cultured in vitro. MethodsThe samples of common bile duct (CBD) scars were collected from 18 patients with benign bile duct scar stricture and 6 cases of normal CBD tissues from liver transplantation donor were collected as control. The expressions of PTGFR and COX-2 were detected by immunohistochemical strept-avidin-biotin complex (SABC) method. Semiquantitative RT-PCR and ELISA methods were used to detect the mRNA and protein levels of PTGFR in bile duct fibroblasts which were effected by TGF-β1 with different concentrations (0, 10, 20, and 30 ng/ml) for 24 h. ResultsThe positive rates of PTGFR and COX-2 were 88.9% (16/18) and 83.3% (15/18) in tissues of benigh CBD scar and 33.3% (2/6) and 0 (0/6) in normal CBD tissues (Plt;0.05). The expressions of the PTGFR mRNA and protein levels became upregulated when the concentrations of the TGF-β1 became higher in human bile duct fibroblasts (Plt;0.05). And the effect was concentration dependant to some extent. ConclusionsThe high expressions of PTGFR and COX-2 play important roles in the process of benign bile duct stricture formation. TGF-β1 is able to induce higher expressions of PTGFR mRNA level and the PTGFR protein level in a concentration dependent manner, and regulate the formation of benign bile duct stricture.

Objective To investigate the clinical applications of plasma shock wave lithotripsy （PSWL） in the treatment of calculi via choledochoscope. Methods Between 2004 and 2009, 56 huge residual calculi (54 cases) were underwent PSWL via choledochoscope treatment in our hospital. Calculi size: diameter ≤10 mm in 9 calculi, 10 mm lt;diameter ≤15 mm in 24 calculi, 15 mm lt;diameter ≤20 mm in 17 calculi, and diameter gt; 20 mm in 6 calculi. Twenty four cases of these 54 patients had bile duct stricture. Procedure: Firstly found the calculus, and then the lithotriptor wire was introduced to the place 0.5-1.0 mm far away from the calculus surface through choledochoscope channel, and powered on, fired, destructed. Results Forty-eight cases of 54 patients were cured by PSWL with 1 times, 2 cases with 2 times, 2 cases with 3 times, and 2 cases with 4 times. Shock 4-300 times were exported per PSWL, with an average of 65 times. Crushing each stone needed shock for 4-680 times, with an average of 77 times. The calculi were ruptured in different degrees by PSWL, of which 20 cases were completely ruptured. All calculi were completely extracted. Except one case with bile duct stricture was found a small amount of bile duct bleeding during operation, all other patients had no operation complications. Conclusion PSWL technique plays an important role in lithotripsy. It is easy to deal with intrahepatic impacted calculi by PSWL, especially the pigment stones with rough surface.
ObjectiveTo explore the curative effect of precise hepatectomy techniques in hepatolithus. MethodsTotally 132 patients underwent precise hepatectomy and 52 patients underwent irregular hepatectomy were retrospectively analyzed, and the intraoperative and postoperative indexes such as operation time, blood loss, postoperative complications, hospitalization time, clearance rate of calculus, and cost of hospitalization were analyzed. ResultsCompared with the patients in irregular hepatectomy group, although the operative time was longer in precise hepatectomy group 〔(364.6±57.8) min vs. (292.9±44.7) min, Plt;0.001〕, but the patients in precise hepatectomy group had less blood loss 〔(558.3±90.6) ml vs. (726.7±88.7) ml, Plt;0.001〕, less postoperative complications (11.4% vs. 23.1%，P=0.004 3), and higher clearance rate of calculus (89.4% vs. 73.1%, P=0.005 5). Thus, the patients in precise hepatectomy group had shorter hospital stay 〔(22.9±4.4) d vs. (28.8±3.5) d, Plt;0.001〕 and less cost of hospitalization 〔(1.8±0.7)×104 yuan vs. (2.1±0.9)×104 yuan, P=0.016 5〕. Conclusion Precise hepatectomy is better than irregular hepatectomy in treatment for hepatolithus.
