资料收集中的护患沟通交流技巧

正确的护理评估依赖于资料收集的充足与准确。因此资料收集是否全面、系统、真实、及时，直接影响着护理诊断和护理措施的正确制订。如何应用护患沟通技巧，准确、及时、全面地收集资料保证护理质量是当今护理工作应关注的重要内容。     

人胰胆管合流异常胆汁对胆管细胞的影响及其机理探讨

目的研究胰胆管合流异常(APBDU)患者的胆汁对人胆管细胞生长的影响,探讨APBDU与胆管癌发生的关系。方法应用四甲基偶氮唑蓝(MTT)比色法检测APBDU患者胆汁对胆管细胞增殖的影响,流式细胞仪测定其细胞周期分布及凋亡情况;Western blot法检测经APBDU胆汁处理的胆管细胞c-erbB-2蛋白表达水平的变化。结果APBDU患者胆汁与正常对照胆汁比较,能明显促进胆管细胞的增殖(P<0.05),这种促增殖作用可被环氧化酶COX-2抑制剂celecoxib或一氧化氮合成酶抑制剂L-NAME抑制;流式细胞仪分析经APBDU胆汁处理的胆管细胞其处于S期的细胞明显增多(P<0.001);Western blot法检测经APBDU胆汁处理的胆管细胞其c-erbB-2表达增多。结论APBDU患者的胆汁对正常胆管细胞增殖有促进作用,可能潜在致癌活性。     

肝移植术后缺血型胆道病变的介入治疗进展

肝移植是终末期肝病最有希望的治疗方法之一。移植肝缺血型胆道病变逐渐成为肝移植术后胆道并发症的主要类型，其病因及发病机制复杂，临床处理棘手，日益成为影响肝移植患者长期成活及导致移植物丢失的主要原因之一。国内外尝试用多种方法来预防和治疗缺血型胆道病变，介入治疗被认为是首选治疗方法，疗效显著。     

腹腔镜胆囊切除术致胆管的热力损伤

目的探讨腹腔镜胆囊切除术致胆管热力损伤的原因、特点、处理及预防方法。方法回顾总结我院1992-2002年间收治的腹腔镜胆囊切除术致胆管热力损伤的8例临床资料。结果6例表现为穿孔性损伤：右肝管损伤1例，肝总管损伤4例，胆总管损伤1例，经过1次或1次以上手术治疗后痊愈；2例表现为延迟性胆管狭窄，均为肝总管损伤，再次手术后痊愈。随访1．5～9年，无胆管狭窄。结论与机械性胆管损伤相比，腹腔镜胆囊切除术致胆管热力损伤具有一定的特点，且其病情复杂、处理困难、处理方法灵活多样；娴熟的腹腔镜技术、正确掌握中转开腹指征以及丰富的胆道外科经验是预防和处理胆道热力损伤的关键。     

胆道消融剂在选择性胆道消融栓塞中的选用

目的 观察不同胆道消融剂选择性胆道消融栓寒对肝脏结构和功能的影响。方法无水乙醇、醋酸、盐酸、氧氧化钠分别消融姐道，OB胶栓塞巴马小型猪左外叶胆管，观察术后肝功及病理变化。结果术后各组肝功能各项指标除白蛋白外．均出现一过性增高，术后两周内恢复正常。尤水乙醇肝功变化没有其他组显著。其它各组坏死范围较无水乙醇大。其中氢氧化钠出现急性肝坏死，醋酸坏死范围大于左外叶。光镜下左外叶汇管区纤维明显增生，肝细胞数目减少。假小叶形成。Masson染色提示胶原纤维显著增生。结论无水乙醇与OB胶联合使用．行选择性胆道消融栓塞能使消融栓塞胆道引流区域肝组织萎缩纤维化，肝内假小叶形成。而且对机体影响最小，是目前安全的胆道消融剂。     

小切口胆囊切除术中胆道损伤的预防

目的探讨预防小切口胆囊切除术（MC）中胆道损伤的方法。方法对本组15131例MC中发生的18例胆道损伤进行回顾分析。结果1994年12月前施行MC2321例，发生胆道损伤9例（0．39％），1995年以来实施MC12810例，发生胆道损伤9例（0．07％）。结论思想上高度重视、规范手术适应证、规范手术操作是预防MC中胆道损伤的关键。     

ENDOSCOPIC OBSERVATION OF MUCOSAL SPREAD LESION OF CHOLANGIOCARCINOMA USING PERORAL CHOLANGIOSCOPY WITH NARROW BAND IMAGING

A 69‐year‐old man was admitted to Toho University Omori Medical Center complaining of icterus. Abdominal computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography were suspicious of cholangioma of inferior bile duct. Peroral cholangioscopy using narrow band imaging (NBI) was performed and it was possible to diagnose the mucosal spread lesions of cholangioma. Histological findings reflected the endoscopic findings. Mucosal spread lesions of cholangiocarcinoma were successfully diagnosed using the CHF‐B260 for NBI.     

CLINICAL EVALUATION OF PERORAL CHOLANGIOSCOPY FOR BILIARY DISEASE USING NARROW BAND IMAGING

Regarding peroral cholangioscopy (POCS) for biliary disease, due to the recent appearance of a video cholangioscope that can obtain high‐quality images, it is possible to observe subtle changes of the biliary mucosa. In addition to the conventional observation method using POCS, the biliary mucosa with also observed with narrow band imaging (NBI) in one case of chronic cholangitis and four cases of extra hepatic bile duct tumor (three surgical cases). In the conventional observation method, the vessels in the surface layer of the biliary mucosa could be observed more clearly using NBI. In one case in which a tumor was observed, the irregularity of the biliary mucosa became clear on NBI, and the vessels inside a papillary tumor could also be easily observed. In another case of bile duct tumor, the conventional observation method showed a region in the proximity of the tumor where the vessels could not be seen clearly, but they could be seen clearly on NBI. In all of the cases, the bile juice was seen as red on NBI, which disturbed the observation. With POCS using NBI, it was possible to observe the vessels and irregularities in the surface layer of the biliary mucosa more clearly than with conventional observation methods.     

经结膜下穹隆至上颌窦插管术治疗泪道阻塞的临床研究

采用经结膜囊下穹隆至上颌窦插管的术式引流泪液，治疗泪道阻塞引起的溢泪症，获得较为满意的效果。手术的主要步骤是：局麻后于结膜囊下穹隆内1／3区作一4mm长的结膜切口，自筋膜下分离至眶线下5mm。从切口伸入上颌窦骨钻钻通上颌窦顶壁，插入长短适度的义管，并向管内注入生理盐水，证实有液体流入鼻咽部后，固定义管。术后定期冲洗，无需拆线，应用这种术式治疗泪道阻塞引起的溢泪症218眼，其中溢泪完全消失151眼占82．1％，溢泪减轻的27眼占14．6％，总效率96．7％。
