Surgical Complications and Long-Term Outcome of Different Biliary Reconstructions in Liver Transplantation for Primary Sclerosing Cholangitis—Choledochoduodenostomy versus Choledochojejunostomy

Choledochojejunostomy (CJS) is commonly used for biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC). We alternatively performed choledochoduodenostomy (CDS) and side-to-side choledochodocholedochstomy in a large cohort of patients. Fifty-one patients with PSC, transplanted between 1988 and 2000, were analyzed retrospectively. Biliary reconstruction was CDS in 25 (49%), CJS in 20 (39%) and CC in 6 transplantations (12%). Biliary leaks occurred in the early follow-up (< or =41 days) only in CDS patients (20%). However, in the late follow-up (>4 months), stricturing of anastomosis was found once in CDS (4%) and CJS (5%). Later (>9 months), intrahepatic bile duct strictures were diagnosed in four CDS (16%), one CJS (5%) and one CC (17%) patient(s). In 48% of CDS (12/25), 60% of CJS (12/20) and 17% of CC (1/6) at least one incidence of cholangitis was observed. Overall, biliary complication rates were significantly higher in CDS (40%) than CJS (10%) and CC (17%); of those none in CC and 12% in CDS were anastomosis-related. Graft/patient survival showed no significant differences among groups. Based on our results we consider CJS the standard method for biliary reconstruction in PSC; however, in selected cases where CJS is difficult to accomplish because of previous surgery or for retransplantation, CDS may present an alternative technique.     

Surgical approach after failed enteryx injection for GERD.

OBJECTIVE: We report on 3 patients who underwent laparoscopic antireflux procedures for persistent symptoms of GERD after biopolymer injection. METHODS: Experienced laparoscopic surgeons completed all 3 procedures laparoscopically. In 2 patients, there was an extramural extravasation of the polymer outside and adherent to the esophageal wall. In these patients, a partial posterior fundoplication was used. The third patient, who had the polymer material deposits removed preoperatively by endoscopic mucosal resection, underwent a Nissen fundoplication. RESULTS: Postoperative recovery was uneventful in all cases. At follow-up of 6 to 12 months, all patients were symptom free, off medical therapy, and experiencing no dysphagia. CONCLUSION: Surgical therapy for patients after failed biopolymer injection is safe and effective. The choice of surgery may depend on whether the polymer mass can be removed preoperatively.     

Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.     

十二指肠镜、腹腔镜联合治疗肝外胆管结石

目的探讨十二指肠镜联合腹腔镜治疗胆囊结石并胆管结石的临床效果。方法回顾分析7年间106例胆囊结石并胆管结石患者的临床资料。106例均先行内镜下十二指肠乳头切开(EST)取石、鼻胆引流(ENBD)然后行腹腔镜胆囊切除术(LC)。结果EST取石成功101例(95.3%);并发症包括胰腺炎(高淀粉酶血症)11例(10.4%),出血1例,急性胆管炎2例,均经对症处理治愈。全组病例无死亡,均痊愈出院。85例获平均3.1年随访,术后复发胆管结石5例(5.9%),十二指肠乳突部再狭窄1例;另发生胆管癌2例,其他原因死亡2例。结论联合EST和LC治疗肝外胆管结石是一种安全有效的微创手术方法。     

肝门胆管癌的外科治疗60例临床分析

肝门胆管癌近年有增多趋势,本文报告我院1975年～1985年间肝门胆管癌60例,占全部肝外胆管癌82例之73.1％,占同期全部胆道手术3626例之1.65％。临床表现主要有三型:1)阻塞性黄疸29例,其中25例曾误诊为肝炎;2)急性胆管炎12例;3)长期胆道疾病14例,其他5例。本组行B超检查19例,ERCP10例,PTC39例。最后诊断根据PTC和/或ERCP,剖腹术及病理检查结果。 56例施行了手术治疗,仅6例施行肿瘤连同半肝切除,姑息性肝胆管内引流15例,外引流23例,其他方法12例。平均存活时间:6例切除组24.5月,48例姑息手术组8.7月,未手术的4例为5月。文中强调早期诊断,凡40岁以上出现阻塞性黄疸或“传染性肝炎”均须警惕胆管癌,进行B超,CT,ERCP或PTC检查,文中强调PTC是诊断本病重要手段,可选择进行右左肝管PTC。本病应争取手术切除,不能切除者行肝胆管内引流或外引流,二者疗效无明显差别。     

经内镜胆管引流术在肝门部恶性胆管梗阻中的应用及其评价

肝门部恶性肿瘤手术切除率极低，临床处理十分棘手。作者采用内镜胆管引流术治疗此类肿瘤２８８例次（肝门部胆管癌１８４例、胆囊癌２３例、肝细胞癌侵犯肝门部胆管４７例、其他转移性肿瘤３４例），其中行内镜鼻胆管引流１６２例次、塑料内置管引流８０例次、放置可膨式金属胆道支架４６例、４例患者接受同期双内置管引流。引流总有效率为６７．０％，其中效果满意者４３．１％；４０例患者术后１个月内发生胆管炎，发生率为１３．８％，３例死亡；长期随访病例的平均存活期５．３个月。我们观察到治疗的效果与Ｂｉｓｍｕｔｈ分型有密切关系，如果全肝４０％以上的胆系得到引流，黄疸有望消退；左、右两侧胆管同时引流可扩大引流范围，提高疗效；应合理选择三种内镜胆管引流方法并适时灵活转换才能获得满意的疗效。结论：对于肝门部肿瘤，内镜胆管引流术是一种安全有效的治疗手段，可作为首选的姑息性治疗。

失去肝动脉血液供应后大鼠肝门部胆管周围血管丛变化的三维构像研究

目的 探讨完全失去肝动脉血液供应后，大鼠肝门部胆管周围血管丛（PBP）的形态学变化。方法 将SD大鼠随机分为两组，对照组仅游离胆总管、门静脉、腔静脉和肝总动脉，不做切断；实验组结扎肝动脉，并切断肝十二指肠韧带除门静脉以外的其它组织，阻断其它侧支血管对肝门部胆管的血液供应。术后应用计算机对大鼠肝门部组织切片进行PBP三维可视化构建，并对PBP内层微血管进行定量分析，对胆管壁组织进行病理学检查。结果 实验组肝门部胆管分叉部位PBP平面结构显示胆管扩张，胆管壁明显增厚，壁内微血管尖细，排列紊乱，内层微血管密度减低；PBP立体构像显示空间结构紊乱，不规则，微血管细小，管壁不均匀增厚。与对照组相比，实验组肝门部PBP内层微血管总数明显减少（P〈0．01），肝门部PBP内层微动脉数也明显减少（P〈0．05）。实验组肝门部胆管壁呈慢性增生性炎症改变。结论 失去含氧量高的动脉血液供应时，PBP形态结构将会发生一系列改变，胆管壁组织也将发生相应的病理变化。     

胆汁胆固醇对胆囊收缩素受体表达的影响

目的：探讨胆汁胆固醇对胆囊收缩素受体（CCK－R）表达的影响。方法 采用放射免疫分析法和受体放射配基结合法检测对照组、高胆固醇组、自然恢复组及治疗组豚鼠门静脉血CCK水平、胆囊CCK－R的最大结合容量（Bmax）和亲和力（Kd），同时观察空腹胆囊体积（FV）、胆囊胆汁量（FB）和餐后胆囊体积（RV）、胆囊胆汁量（RB）及胆囊收缩率（E％）、胆汁胆固醇浓度的变化。结果 与对照组比较，高胆固醇组豚鼠FV、FB增大（P＜0.05），RV、RB也增大，胆囊收缩率下降（P＜0.01），胆汁胆固醇浓度升高（P＜0.05），门静脉血CCK水平及CCK－R的Kd无改变，而CCK－R的Bmax下降（P＜0.01）；治疗组上述各项指标正常。结论 胆汁中的高胆固醇通过下调胆囊CCK－R表达而导致胆囊收缩功能障碍，降低胆汁高胆固醇浓度可以促进胆囊动力功能的恢复。
