目的 探索急性化脓性梗阻性胆管炎20世纪90年代后期与80年代以前的差异，探讨对本病治疗的方向。 方法 收集我院1996～2000年病例，并与我院1950～1981年资料进行比较。 结果 ①发病率显著降低，从46.08%降至15.62%； ②发病年龄延后10～20岁； ③入院时病情相对较轻，有休克者从51.39%降至22.80%； ④病死率明显下降，从25.78%降至3.50%； ⑤再手术患者显著增加，从12.12%增至55.20%。造成上述差异的原因与患者就诊早，及时的治疗，医务人员的水平提高，药品与医学的发展等有关。 结论 对急性梗阻性化脓性胆管炎患者，虽然发病率和死亡率已明显下降，仍需足够重视，因术后T管造影和B超检查发现肝内残石或胆管狭窄者，高达85.1%，复发再手术率达55.2%，远不能令人满意。为提高远期效果，应在急诊手术引流后，待患者病情平稳后，再进一步检查和彻底处理肝内病变。
Objective To investigate the phenotypic change and proliferation of fibroblasts in human inflammatory strictured bile duct wall. Methods We observed the density and ultrastructure of fibroblasts, and the histologic structure in human normal bile duct wall and inflammatory strictured bile duct wall by light and electron microscope.Results The results showed that fibroblasts were the main source of extracellular matrix production in bile duct wall. The phenotype of fibroblasts in inflammatory strictured bile duct wall changed obviously, quiescent fibroblasts were activated and transformed to myofibroblasts, with massive proliferation. Conclusion These data suggest that massive proliferation of activated fibroblasts and myofibroblasts is the main source of extracellular matrix overproduction which results in inflammatory bile duct stricture.
The contents of lipid peroxides(LPO)and vitamin E(V.E)and some functional index and histologic changes in the lungs from the the rabbit models of acute cholangitis of severe type(ACST)were measured dynamically.The results revealed that the V.E content decreased strikingly from 6 hours and the LPO level increased progressivelg from 12 hours in the lungs.Simultanuosly,the congestion and neutrophil infiltreation in the lung mesenchyme,and the endothelial cell damage and thrombosis in the lung blood capillaries had been observed.These suggest that acute lung injury induced by ACST is referable to the lipid peroxidation damage to the lung blood capillaries which is due to increased LPO and decreased antioxidants including V.E.
目的:探讨糖尿病合并化脓性胆管炎(acute obstructive suppurative cholangipis,AOSC)患者围手术期护理方法。方法:回顾性分析我院2002 年1月至2008 年8 月收治的15 例糖尿病合并化脓性胆管炎患者的临床资料。结果:本组2例术后伤口裂开,1例切口裂开胆道大出血死亡,3 例发生肺部感染,无低血糖休克病例,9例伤口愈合良好,按期拆线。结论:加强围手术期的观察和护理,对糖尿病合并化脓性梗阻性胆管炎患者的治疗起着重要作用。
【摘要】目的 探讨急性重症胆管炎(ASC)患者的手术时机、治疗方式的选择以及患者围手术期的治疗。方法 回顾性分析156例ASC患者的临床资料。结果 治愈131例，死亡25例，总死亡率为16.0%。入院后行急诊手术者32例，术后死亡9例，死亡率28.1%； 入院后经支持治疗、纠正休克和酸碱失衡及抗感染治疗后再行手术者53例，死亡9例，死亡率为17.0%。行ERCP+乳头括约肌切开术治疗17例,行PTCD 治疗12例,行保守治疗42例。结论 对ASC患者掌握好手术时机，根据病情选择治疗方式，重视围手术期支持治疗以及适时手术治疗，是降低死亡率，提高疗效的重要措施。
Objective To study the neural mechanism of hypotension or shock state in acute cholangitis in severe type (ACST) and its value of clinical application. Methods A technique of blocking abdominal splanchnic nervi via right adipose capsule of kidney was carried out on 28 patients by injecting 1% lidocaine before urgent operation. Results After blocking the relevant nervi, hypotension or shock state in 23 patients were improved significantly (Ｐ＜0.05). The death rate was lower (14.3%) after having performed biliary decompressions with laparotomy. Conclusion Patients′ hypotension or shock state at the early phase of ACST is the result of neural reflex in which the splanchnic nervi is its afferent pathway. Blocking the relevant nervi before urgent operation, the valuable opportunity of emergency treatment can be obtainded and the complication and death rate are reduced significantly.
Objective To investigate the recurrence of hepatolithiasis and reoperation and their relation to the location of intrahepatic stone. MethodsTwo hundred and twentysix patients of hepatolithiasis operated upon in the period of 1990-1995 were retrospectively analysed.ResultsAmong those patients, there were 101 patients (44.7%) had previous operation for the gallstones diseases including cholecystectomy for gallbladder stones (n=21, 20.8%), choledocholithotomy (n=72, 71.3%),liver segmentectomy (n=6， 5.9%), and choledochojejunostomy (n=2, 2.0%). The operative mortality was 5.0% for the reoperation group and none for the first time operation for hepatolithiasis.Conclusion Although the liver resection is an ideal surgical method to eradicate the diseased lesion and to minimize the malignant changes especially in primary hepatolithiasis (type I, or IE)， choledochojejunostomy is only recommended for the secondary type (type IE or IE) where possible. In the management of hepatolithiasis, the complete information of biliary tract is needed for the choice of surgical methods.
To evaluate the effect of intercellular adhesiveness molecule-1 (ICAM-1), E-selectin on hepatic microcirculation in acute cholangitis. The Changes of hepatic tissue, content of blood flow and Evan′s blue (EB) in hepatic tissue in acute cholangitis were determinated. Results: The number of PMN in hepatic tissue and sinusin increased, degenaration and necrosis of the hepatic cells and hepatic sinusoidal endothelial cells and content of blood flow in liver were reduced, and content of EB in hepatic tissue increased remarkbly in the rats with acute cholangitis. Pretreatment of anti ICAM-1 and E-selectin mAb reduced the damage of hepatic microcirculation. Conclusion: ICAM-1 and E-selectin may play an important role in damage to hepatic microcirculation in acute cholangitis.
The authors observed the progressive changes of the platelet activity in 25 cases of acute cholangitis severe type(ASCT)within 2 weeks of pre-and-post-operation.The results revealed that there are signficant changes of the platelet activity in ASCT.The levels of the platelet activity were proportional to the severity of disease and degree of biliary duct obstruction.Persistency of abnormality of platelet activity may predict the worse of disease and bad prognosis.The results are useful to understand the complex changes of pathophysiology in ACST,to the mechanism of multiple organic failure.
