ObjectiveTo evaluate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) for biliary strictures post-orthotopic liver transplantation (OLT). MethodsA systematic review was performed by searching electronic bibliographic databases, including the Cochrane Library, Medline, EMbase, CNKI, and WanFang from 1994 to 2014. The pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were used to describe the diagnostic value. Summary receiver operating characteristic (SROC) curve with area under the SROC curve (AUC) were used to summarize overall diagnostic performance. ResultsSix studies involving 261 subjects were eligible for the analysis. The summary estimates of pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and AUC of MRCP for the diagnosis of biliary strictures after OLT were 89% (95% CI:0.83-0.94), 94% (95% CI:0.88-0.98), 8.04 (95% CI:2.83-22.85), 0.11 (95% CI:0.04-0.37), and 0.961, respectively. ConclusionMRCP is a sensitive and specific technique to diagnose biliary strictures after OLT.
The structure of 39 specimens of hepatobiliary duct stones with strictures were studied histologically. The elastic and collagenous fibers were studied by quantitative analysis. The results show that the epithelium of the sttnotic bile duct are intact but with proliferation. The mitochondrions are degenerated and broken, the endoplasmic reticulum are dilated, suggesting the functional impediment of these epithelium. The mucous glands are markedly proliferated fibrosis are found near the glands which are destroyed .Some of the elastic fibers are destroyed and arranged disorderly . Hyaline degeneration was observed in collagenous fibers with remarkable increase of the volume density.
In 1983-1994,748 cases hepatocholelithiasis had been treated in our department, in which 372 patients underwent hepatectomy and 43 patients underwent hepatectomy of the quadrate lobe. Hepatectomy of the quadrate lobe has been performed to treat all kinds of hepatocholelithiasis, it is easy to expose 1 or 2 degree branch of biliary tree, incise the hepatobiliary stricture and perform hepatocholangiojejunostomy in the hepatic hilum.
【Abstract】ObjectiveTo improve curative effects in the treatment of hilar bile duct stricture. MethodsIntrahepatic cholelithiasis was associated with the development of hilar bile duct stricture.Plastics of hilar bile duct stricture (PHBDS) using pedicled cholecystic graft and Roux-en-Y cholangiojejunostomy (RYCJ) were performed. The patients with hepatolithiasis treated with PHBDS or RYCJ between Jan. 1994 and Jan. 2004 were retrospectively analyzed.ResultsFollow-up was carried out from 16 months to 87 months with an average of 47 months. The postoperative morbidity of cholangitis was 5.66% and 21.88% (P=0.010) and recurring rate of hepatolithiasis was 3.77% and 16.67%(P=0.021).ConclusionPHBDS can preserve the physiological compatible, convenient and effective in treatment of hilar bile duct stricture. The late result after operation of PHBDS is better than that of RYCJ.
目的 减少肝内胆管结石术后的残留。方法 回顾性分析近5年我科收治的50例肝内胆管结石病例行病灶肝切除并结合术中、术后胆道镜应用的近期疗效及术后残石率。结果 术后近期并发症发生率为8%，无胆漏、肝衰及手术死亡发生，术后B超、逆行T管造影及术后胆道镜检查证实的即期残石率仅4%（2例）。结论 减少肝内胆管结石术后结石残留的关键是术中术后胆道镜的使用，肝内及肝门胆管狭窄的彻底处理； 依据狭窄胆管所引流区域行“根治性”的肝组织切除是取尽结石，清除病灶的合理方法。
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.
An retrospective analysis of 112 cases with localized left hepatolithiasis (LLH) treated in our center in recent two decades was made. The results showed: ①Coexisting involvements of both left external hepatic duct (LEHD) and left medial hepatic duct (LMHD) were the most common pathological pattern (83.08%), came next the only LEHD involvement (12.31%). There was no localized LMHD caculi in this group. ②The rate of concomitant LHD stricture was 59.82% and that of LMHD or LEHD were 84.85% and 84.00% respectively, in which severe degrees dominate. ③Lateral segmentectomy was the most common clinical practice for LLH (58.93%), and left lebectomy was much less frequently used (12.50%), although the latter led to a significantly smaller rate of residual (7.14% vs 21.21%) and had a satification follow-up rate of 85.71% being superior to lateral segmentectomy (46.97%), or cholangiojejunostomy (40.00%), bile duct exploration and drainage (0). ④The most common prognostic factors were residual or recurrent stones of LMHD (62.50%) and residual LHD stricture (37.50%). ⑤There was no significant difference between left lobectomy and lateral segmentectomy in length of operation, intraoperative bleeding, and postoperative complications. The results indicate that too much dependence on lateral segmentectomy in the management of LLH is one of the most important factors affecting the longterm results, for which left lobectomy is an applicable and safe therapy of choice.
Eighty two cases of acute gallstone pancreatitis on early operation are reported and the significance of the clinical picture and pathology are analysed. The data showed that gallstone was found in 85.5%, among the cases of them mulliple gallstone was 71.1%, dilated cystic duct was 26.4%, common bile duct stone 36.8%, distal bile ductal stricture was found in 9.3%, and anomalous conjunction of biliary and pancreatic duct was 20.1%. Sixteen cases with serious pancreatitis were determined on operation, but death rate was 3.7% only. The authors claim that early operation may be of value in patients of acute gallstone pancreatitis with or without jaundice espesially in bile duct obstruction.
目的 探讨胆道术后肝内、外胆管狭窄的治疗方法。方法 回顾性分析吉林大学第一医院自2003年1月至2007年12月期间应用胆道镜对37例胆道术后肝内、外胆管狭窄患者行气囊扩张治疗的结果。结果 本组37例患者42处肝内、外胆管狭窄均行胆道镜下气囊导管扩张，29例（78.4%）系胆管狭窄伴肝内胆管结石，经气囊扩张后，胆道镜通过狭窄部位，取净远端胆管结石； 另8例（21.6%）系单纯胆管狭窄无结石,仅行导管扩张。本组成功率达97.3%（36/37）； 1例因胆汁性肝硬变伴弥漫性胆管狭窄扩张失败后行肝叶切除手术。27例狭窄仅需一次性扩张,9例因胆管多处严重狭窄而行多次扩张。全部患者均获随访，随访时间6~24个月,平均12个月，未见结石复发。结论 胆道镜下气囊导管扩张治疗胆管狭窄微创、直观、安全、简便易行且疗效可靠,是治疗胆管狭窄并取净结石的理想方法。但需注意操作方法及技巧，防止并发症的发生。
