目的探讨肠外和肠内营养支持在克罗恩病围手术期的应用价值。方法对我院1995～2001年经手术治疗的20例克罗恩病进行回顾性分析。结果经肠内及肠外营养支持后，该20例克罗恩病围手术期的各项营养指标均有不同程度改善，且无营养不良的并发症发生。结论营养支持是克罗恩病围手术期的重要治疗手段，适时合理地应用肠外和肠内营养，有助于提高该病的手术疗效。
【Abstract】Objective To analysis the clinical characteristics, pathogenesis, diagnosis and treatment of acute acalculous cholecystitis.Methods Seventy-nine cases of acute acalculous cholecystitis from January 1996 to January 2003 were retrospectively reviewed.Results Of those 79 cases, 13 cases were treated nonoperatively and 66 cases were treated operatively. Twentythree cases were suppurative, 43 cases were gangrenous with perforation in 18 cases，which were proved by postoperative pathology. Seventysix cases were cured and 3 cases were dead. Conclusion Keeping vigilant alert, observing dynamically as well as appropriate operative intervention are effective to improve the prognosis of acute acalculous cholecystitis.
ObjectiveTo summarize the research progress of tissue-engineered bile duct in recent years. MethodsThe related literatures about the tissue-engineered bile duct were reviewed. ResultsIn recent years, the research of tissue-engineered bile duct has made a breakthrough in scaffold materials, seed cells, growth factors etc. However, the tissue-engineered bile duct is still in the research stage of animal experiments, which can not be directly applied to clinical practice. ConclusionsThe research of tissue-engineered bile duct becomes popular at present. With the rapid development of materials science and cell biology, the basic research and clinical application of tissue-engineered duct will be more in-depth research and extension, which might bring new ideas and therapeutic measures for patients with biliary defect or stenosis.
ObjectiveTo explore the clinicopathological characteristics of combined hepatocellular and cholangiocarcinoma (cHCC-CC), and the prognostic factors associated with survival. MethodesThe clinical features of 31 patients with cHCC-CC from 1995 to 2010 in West China Hospital of Sichuan University underwent liver resection were analyzed retrospectively. The prognostic factors were analyzed by using univariate and multivariate analysis. ResultsOf these 31 patients, 25 men and 6 women, with a median age of 58 years, underwent liver resection for cHCC-CC. Twentythree cases (74.2%) showed positive of hepatitis B surface antigen (HBsAg), 13 cases (41.9%) had elevated AFP≥20μg/L, 18 cases (58.1%) with liver cirrhosis, 8 cases (25.8%) showed presence of lymph node metastases. The 1-, 3-, and 5-year overall survival rates of these patients were 61.3%, 32.3%, and 12.9%, respectively. Univariate analysis showed that invasion of portal vein, microscopic tumor thrombi, positive resection margins, and lymph node involvement were significant prognostic factors. Multiple analysis revealed the positive resection margins and lymph node involvement were independent prognostic factors for overall survival. ConclusionsThe prognosis of patients with cHCC-CC is poor. R0 resection is the only available treatment in curing these patients.
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 探讨胆源性肝脓肿的诊治方法。方法 对我院2000~2004年期间收治并确诊为胆源性肝脓肿的12例患者进行分析，在应用抗生素和全身支持的前提下，再依据其病变发生、发展的不同阶段采用不同手段治疗。结果 4例急性期患者中2例行急诊胆道引流手术后治愈，另2例转为亚急性期（脓肿融合期）； 6例亚急性期患者均经B超导向下行脓肿穿刺抽脓后注入抗生素治疗后治愈； 4例慢性期患者行脓肿切开引流后治愈。结论 本病在应用广谱抗生素（二联抗生素）和全身支持治疗的前提下，再根据病变不同时期采用不同方法治疗，可获得良好效果。
