【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.
Immunohistochemical study on 39 specimens of hepatobilibary duct stricture due to stones were performed. Collagen types Ⅲ and Ⅳ were studied by quantitative analysis. The results showed that significant increase of type Ⅲ collagen was found in the stenotic bile duct wall, the portal area and liver sinusoid with fibrosis. Abnormal increasing of type Ⅳ collagen was found in the liver sinusoid of the stenotic bile duct.
Objective To investigate the anatomic factors on iatrogenic biliary injury for elevating surgical safety and decreasing incidence of iatrogenic biliary injury. Methods The clinical data of 39 patients with iatrogenic biliary injury and anatomic varied factors in operation records from January 2000 to August 2009 in The Second Affiliated Hospital of Kunming Medical College were analyzed retrospectively. Results Thirty-nine patients with iatrogenic biliary injury were divided into 5 types according to Bismuth typing, including type Ⅰ 6 cases, type Ⅱ 19 cases, type Ⅲ 8 cases, type Ⅳ 5 cases, and type Ⅴ 1 case. Anatomic varied factors included bile duct variation in 15 cases, cystic duct abnormal position in 10 cases, vascular variation in 13 cases, and porta hepatis rotation in 1 case. Biliary injuries were found during operation in 6 cases, 24—72 h after operation in 16 cases, and stenosis of biliary duct was found in 17 cases 3 months to 2 years after operation. Two cases were dead because of liver function failure or myocardial infarction, withdraw was 4, the other patients were cured. Conclusion Anatomic factors are important objective elements in iatrogenic biliary injury, paying attention to abnormal anatomic factors can effectively prevent iatrogenic biliary injury.
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.
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.
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.
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。
Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepatic duct strictures. MethodsTwo hundreds and sixteen cases of intrahepatic lithiasis and high hepatic duct strictures treated in this hospital from January 1993 to October 2002 were analysed retrospectively.ResultsOne hundred and eightythree cases underwent different selective operation by selected time; 33 cases complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were reoperated. The operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic repair with own patch and choledochojejunostomy.Two hundreds and six cases were cured,the curative rate was 95.4%; 8 cases improved (3.7%), and 2 cases died (0.9%).Conclusion The best effective surgical treatment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct strictures and to clear the intrahepatic lithiasis. For patients with normal extrahepatic bile duct and Oddi’s function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholangioscopy may play an important role in the treatment of intrahepatic tract lithiasis during operation.
