目的 探讨经皮经肝穿刺胆道引流术（PTCD）联合胆道支架置入术治疗恶性梗阻性黄疸的操作技巧及其临床应用价值。方法 2009年8月至2011年5月期间中国医科大学附属第四医院介入科对39例恶性梗阻性黄疸患者施行了PTCD联合胆道支架置入术，对其临床资料和效果进行回顾性分析。结果 39例患者全部穿刺成功，穿刺成功率为100％。穿刺左叶胆管11例，穿刺右叶胆管19例，左右胆管均行穿刺9例；单纯外引流22例，内外引流17例；引流管保留7～14d后均成功行胆道支架置入术。 33例患者自觉症状有缓解。患者术后14d时，其白蛋白、碱性磷酸酶、丙氨酸转氨酶、总胆红素、直接胆红素和间接胆红素水平均较术前降低（P＜0.05）。术后发生胆道感染3例（7.69％），发生急性胰腺炎4例（10.26％），发生支架脱落移位1例（2.56％），无胆汁性腹膜炎等并发症发生。本组32例患者获访，随访时间为8d～16.5个月，平均9.4个月。随访期间，27例患者死于肿瘤进展及多脏器功能衰竭；5例患者存活，无黄疸加重症状。结论 PTCD联合胆道支架置入术是一种姑息治疗恶性梗阻性黄疸的有效方法，具有简便、有效、安全、可重复性等优点，但需注意其适应证的选择和并发症的预防。
ObjectiveTo study the effectiveness of liver function, hepatic energy metabolism, regeneration, and apoptosis on the obstructive jaundice rat after partial hepatectomy (PH) combined with internal biliary drainage under the condition of conspicuous bilirubinemia. MethodsOne hundred and twenty male SD rats were used in research, six of whom were divided into sham operation (SO) group. Twenty rats underwent bridge operation between common bile duct and duodenum after 70% PH (70%PH group), and 6 rats out of the 94 rats who underwent common bile duct ligation (CBDL) for 5 d were randomly selected as CBDL group, and the residual rats were done the second operations after 5 d and were divided into three groups: bile duct obstruction combined with reperfusion of bile flow group （BDO-RBF group， n=20), 42% PH with BDO-RBF group (n=20), and 70%PH with BDO-RBF group (n=25). Levels of TB, ALT, ALB, and ALP in serum; HGF, bcl-2 mRNA and protein； ATP, ADP, and AMP; hepatocyte proliferation/apoptosis index in hepatic tissues were dynamically observed after operation (24 h, 72 h, and 7 d), respectively. The liver function and hepatocyte energy metabolism were only detected in the SO group. ResultsRats without obstructive jaundice would have an excellent liver regeneration after 70% PH, while the liver function and hepatocyte energy metabolism could recover rapidly. The liver function, hepatocyte energy metabolism, HGF and bcl-2 mRNA and protein of liver tissue and the hepatocyte proliferation/apoptosis index in partial (42% or 70%) hepatectomy combined with internal biliary drainage in obstructive jaundice group were significantly influenced while recovered rapidly (Plt;0.05). ConclusionsUnder the condition of conspicuous bilirubinemia, the influences of hepatectomy combined with internal biliary drainage on hepatocyte energy metabolism, liver function, hepatocyte regeneration and apoptosis are severer than that of normal rats who underwent 70% hepatectomy, while also make the rats recover rapidly in hyperbilirubinemia groups. The database suggest that it is not necessary to do preoperative external biliary drainage before performing liver resection.
ObjectiveTo investigate the diagnostic value of endoscopic retrograde cholangiopancreatography (ERCP) in obstructive jaundice of elderly patients. MethodsTotally 338 patients with obstructive jaundice underwent ERCP were divided into elderly group (age ≥60 years old) and nonelderly group (age lt;60 years old) based on age. The levels of serum amylase (AMY), ALT, and TBIL in 6, 24, and 48 h after ERCP were detected. The success rate of cholangiopancreatography, accuracy rate of diagnosis, and incidence of complications after ERCP in two groups were analyzed. ResultsThe difference of serum AMY, ALT, and TBIL levels of patients in 6, 24, and 48 h after ERCP were not significant between two groups (Pgt;0.05). The success rate of cholangiopancreatography in nonelderly group was 96.3% (130/135) and in elderly group was 96.1% (195/203), and no difference was found (Pgt;0.05). However, the accuracy rate of diagnosis of ERCP in nonelderly group (84.6%, 110/130) was significantly lower than that in elderly group (98.5%, 192/195), Plt;0.05. The difference of the incidence of complications was not significant between two groups 〔14.8% (20/135) vs. 17.2% (35/203)〕, Pgt;0.05. There was no mortality in two groups patients. ConclusionERCP is a safe, effective, and accurate method, which is of importance to the diagnosis of obstructive jaundice in elderly patients.
【Abstract】ObjectiveTo investigate the protective effect of melatonin on renal injury induced by bile duct ligation in rats. MethodsSixtyfour rats were randomly divided into four experimental groups (n=16 rats per group): the control group (CN), sham operative group (SO), bile duct ligation group (BDL) and bile duct ligation melatonin treatment group (BDL+Mel). Obstructive jaundice was induced by common bile duct ligation. Plasma level of nitric oxide (NO), total bilirubin (TB), direct bilirubin (DB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea nitrogen (BUN) and creatinine (Cr) were measured 4 d and 8 d after operation. NO and inducible nitric oxide synthase (iNOS) in renal tissue were detected at the same time point, too. Histopathological changes of kidneys were examined by HE staining. ResultsIn BDL group, the plasma levels of NO, TB, DB, ALT, AST, BUN and Cr were higher than those of SO group (P＜0.01）, and the level of NO and activities of iNOS in renal tissue were significantly increased (P＜0.01）. However, in BDL+Mel group, the plasma levels of NO, ALT, AST, BUN and Cr were lower than those of the BDL group (P＜0.01）, and the level of NO and activities of iNOS in renal tissue were significantly suppressed (P＜0.01）; histopathological changes of kidneys were improved.ConclusionAugmentation of iNOS activities and increasing of NO production in local tissue contributed to renal injury induced by bile duct ligation, and the mode of melatonin’s protective actions, at least in part, relates to interference with no pathways.
【Abstract】ObjectiveTo study the effects of endothelin (ET) and Xuesaitong injection on hepatic, renal and myocardial tissues after bile duct ligation (BDL) in rabbits. MethodsSeventytwo rabbits were randomly divided into three groups: BDL group (24 rabbits), BDL+Xuesaitong injection group (24 rabbits), and sham operation group (24 rabbits). Each group was subdivided into four subgroups of postoperative 3, 6, 9 and 12 d (6 rabbits in each subgroup). Automatic biochemical analysis equipment was used to detect the levels of serum TBIL, ALT, BUN and Crea. The levels of ET in plasma, hepatic, renal and myocardial tissues were measured with radioimmunological method. ResultsThe levels of ET in plasma, hepatic, renal and myocardial tissues in both BDL group and BDL+Xuesaitong injection group were higher than those of sham operation group (P＜0.01). The levels of ET in plasma and tissues of BDL+Xuesaitong group were lower than those in BDL group (P＜0.05). ConclusionObstructive jaundice can lead to an increase of ET in plasma, hepatic, renal and myocardial tissues, the level of ET increases with the time of obstruction. Xuesaitong injection may play a protective role in the injury of hepatic, renal and myocardial tissues after obstruction by decreasing the level of ET in plasma and tissues.
ObjectiveTo study the changes of lipopolysaccharide binding protein (LBP) in the serum of Wistar rats with obstructive jaundice and to investigate its potential mechanism.MethodsEighty male Wistar rats were randomly divided into obstructive jaundice group (OJ group, n=40） and sham operation group (SO group, n=40）. Before operation and the 5th, 10th, 15th, 20th day after common bile duct ligation, the levels of LBP, endotoxin, tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in plasma were detected in all the rats. ResultsLBP levels in serum increased significantly in OJ group on the 10th day after operation compared with those of SO group. Moreover, LBP levels gradually increased in OJ group with the prolongation of obstructive time. A positive correlation existed between serum LBP and plasma endotoxin, TNF-α and IL-6.ConclusionThe study demonstrates that LBP in serum is high and plays an important role in the pathogenesis of multiple organ injury secondary to obstructive jaundice. It may be an appropriate way to treat patients with obstructive jaundice by decreasing LBP levels in serum.

Objective To observe therapeutical effect of recombinant human growth hormone (rhGH) on postoperative obstructive jaundice. Methods Fourtyeight patients were divided into two groups randomly: control group with 30 patients and rhGH group with 18 patients. After operation, subcutaneous injection of rhGH was administered 8 U/d for a week. At the same time, parenteral nutrition was given to both groups until the patients could eat and drink. Biochemistry examination, endotoxin, tumor necrosis factor, sIL-2R and nutritional status were all measured at following states: before operation 1, 7 and 14 days after operation. Results Body weights of rhGH group on the fourth day after operation and that of control group on the seventh day after operation increased, but the increasing tendency of rhGH group was more prominent than the control group. For blood sugar 7 days after operation, the level of rhGH group was higher than that of control group (P＜0.05). The level of serum albumin, transferrin, prealbumin in rhGH group was higher than that of control goup （P＜0.05）. Blood serum total bile acid,total cholesterol, low density lipoprotein,glutamicoxal acetic transaminase, transglutaminase, total bilirubin, endotoxin, tumor necrosis factor and sIL-2R were all decreased compared with control group (P＜0.01). However, no significant difference was observed in renal function and electrolute between the two groups.Conclusion An improvement of nutrition status and immunologic function can be observed in obstructive jaundice patients after the postoperative administration of rhGH.
Objective To investigate the correlation between the plasma endothelin (ET) and gastric mucosal pathology.MethodsIn this experiment,seven dogs who experienced common bileduct ligation were in experiment group, the other three dogs who underwent shamoperation were control group. By using specific radio immunological method, the plasma ET levels were determined in dogs before and after 1,4,7 d. The total bilirubin levels were determined before and after 1,4,7 d after operation by using carbazotic acid method.The gastric mucosa,7 d after operation, was cut into slices and was examined under the electron microscope and the light microscope.Results In the experiment group,the levels of ET and total bilirubin rose continually and were higher than those in control group. Vascular congestion and oedema were seen in gastric mucosa of common bileduct ligated dogs. Under the electron microscope, we could see the dilated blood capillary and sludging of blood,the intenstitial mucusa cells oedema. Conclusion The increase of plasma ET might lead to impairment of mucosal microcirculation,which might be one of the pathogens that could induce the gastric mucosal damages in common bileduct ligated dogs.
