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。     

Clinical analysis of congenital bile duct dilatation: Experience with 160 patients over a 7-year period

From July 1989, to June 1996, 160 patients with congenital bile duct dilatation (CBD) were treated at our institution. The incidence of CBD at our institution has increased annually. In approximately 90% of patients with CBD there was associated anomalous arrangement of the pancreaticobiliary ductal system, and we concluded that this was one of the main causes of CBD. Pediatric endoscopic retrograde cholangiopancreatography was first introduced to China in 1989, and has been successfully performed in 90.2% of 92 patients at our institution. We found that age at diagnosis was closely related to the subtype, complications, and mortality of CBD. The subtype also correlated with the presenting symptoms. One hundred and forty-seven of the 160 patients underwent surgery. Of these 147 patients, 136 (92.5%) were cured with normal liver function and 9 (6.1%) improved with liver impairment. Two patients died, one of postoperative pneumonia and one of liver failure. We conclude that early radical surgery and careful postoperative follow-up are essential in the prevention of CBD complications such as cholangitis, pancreatitis, biliary stones, and development of carcinoma. This article is based on a special lecture delivered before the 19th meeting of the Japanese Society of Pancreatico-biliary Maljunction, on September 14, 1996, in Tokyo     

A stratified intraoperative surgical strategy is mandatory during laparoscopic common bile duct exploration for common bile duct stones

Background: Open exploration and endoscopic sphincterotomy (ES) remain the preferred treatment of common bile duct stones (CBDS). The recent spread of laparoscopy has worsened the dilemna of choosing between surgical and endoscopic treatment of CBDS. The aim of this study was to critically evaluate the results of our preliminary experience with laparoscopic common bile duct exploration (CBDE) for CBDS. Methods: Ninety-two consecutive patients were prospectively submitted to laparoscopic CBDE. Surgical strategy included an initial transcystic approach or laparoscopic choledochotomy. Failure of stone clearance was managed by conversion to open CBDE or by postoperative ES. Electrohydraulic lithotripsy and papillary balloon dilatation were selectively used. Stone clearance was assessed by choledochoscopy and control cholangiography. Results: The overall laparoscopic stone clearance in this series was 84% (transcystic route 63% and choledochotomy 93%). Conversion to laparotomy was mandatory in 12% of the patients because of incomplete stone clearance and in 5% because of intraoperative complications. Postoperative ES was required in 4% of the patients, giving an overall surgical success rate of 96%. When indicated (small and limited number of stones located below the cysticocholedochal junction, with a dilated and patent cystic duct) the transcystic route had the lower success rate, the higher complication rate, and the shorter operative time and postoperative hospital stay. When indicated (accessible and dilated common bile duct over 7 mm), laparoscopic choledochotomy had the higher success rate, the lower complication rate, the longer operative time, and the longer postoperative hospital stay, which is related to associated external biliary drainage. The hospital mortality included two high-risk patients (2%) and the complications rate was 15%. Conclusions: Laparoscopic CBDE is safe in selected patients. A stratified intraoperative surgical strategy is mandatory in deciding between a transcystic route and choledochotomy with specific indications for each approach. When feasible, laparoscopic choledochotomy is more efficient and safe than the transcystic route, but it is associated with a longer postoperative hospital stay, which is due to external biliary drainage.

肝硬化病人施行胆道手术35例分析

本文对我院近10年来收治的肝硬化病人施行胆道手术35例进行分析，术前漏诊肝硬化12例，占3O％以上，死亡5例，有3例死于胆囊床大出血与术前漏诊有关。作者就术前漏诊原因、术前准备和手术处理体会进行讨论。     

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因     

梗阻性黄疸患者的内毒素血症及其对机体的影响

４９例梗阻性黄疸患者（实验组）和８１例无黄疸的胆系疾病患者（对照组）围手术期外周血的内毒素（ＥＴ）检测结果表明，实验组：①术前ＥＴ阳性率明显高于对照组（Ｐ＜０．００１）；②术后１０～１２ｄ夹闭Ｔ／Ｙ管后ＥＴ阳性率明显低于术前和夹管前（Ｐ＜０．００１）；③伴急性化脓性胆管炎（ＡＣＳＴ）的患者ＥＴ阳性率明显高于无ＡＣＳＴ的患者（Ｐ＜０．００１）；术前口服胆盐的患者ＥＴ阳性率则显著低于未口服胆盐者（Ｐ＜０．００１）．作者认为，本组梗阻性黄疸患者中出现的肾功能障碍、胃肠道出血以及２例患者的死亡，至少部分地与内毒素血症有关。
