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。     

酥胆麒麟膏用于痔瘘术后换药的药效学与毒理学研究（二）

本文通过设一个阳性对照组（马应龙鹰香痔疮膏），一个空白对照组（凡士林）及酥胆麒麟膏大、中、小三个剂量组（１０％、２０％、４０％浓度）进行三个方面的实验研究，证实酥胆麒麟膏具有止血、抗菌、生肌长皮等综合作用，局部外用无毒副作用，安全性高。其止血、生肌长皮作用，优于马应龙麝香痔疮膏；抗金葡萄茵的作用与银灰散相同；抗大肠杆菌的作用犹于银灰散。尤其是２０％酥胆麒麟膏的以上多种作用优于１０％浓度的，等效于４０％浓度的，可作为临床使用时的最佳浓度。     

Abdominal ultrasonography in the diagnostic work-up in children with recurrent abdominal pain

We report on our experience with routine abdominal ultrasonography in 120 children (aged 3–15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. Conclusion The diagnostic value of abdominal ultra‐sonography in unselected children with recurrent abdominal pain is low. However, the direct visualization of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain.

内镜鼻胆管引流术在腹腔镜和开腹胆总管探查术中的应用

目的　评价内镜鼻胆管引流术 (Endoscopicnasobiliarydrainage ,ENBD)配合腹腔镜和常规开腹手术治疗胆总管结石的疗效。　方法　回顾分析 1997年 1月～ 2 0 0 1年 7月应用ENBD配合完成腹腔镜胆总管探查、I期缝合术 4 4例及开腹胆总管探查、I期缝合术 34例。　结果　 78例均手术成功 ,术后无胆漏、胆道出血、胆管炎等并发症。术中结石取净率 10 0 % (78 78)。术后住院时间 :腹腔镜组为 (6 2±1 3)d ,开腹组为 (7 4± 2 1)d。随访 5 7例 ,时间 (1～ 4 5 )年 ,平均 2 6年 ,腹部彩色B超检查无胆管狭窄及结石复发。　结论　ENBD配合腹腔镜和开腹胆总管探查取石、胆总管I期缝合术安全、可靠。

EFFECTIVENESS OF CYTODIAGNOSIS WITH PANCREATIC DUCT LAVAGE FLUID FOR PANCREATIC DUCTAL CARCINOMA: NEW SAMPLING TECHNIQUE

Background: Pancreatic carcinoma is one of the most lethal cancers. Because pancreatic carcinoma is still very difficult to diagnose in its early stage, many of these patients will be considered unsuitable for surgery. If a cytological diagnosis is obtained at initial endoscopic retrograde cholangiopancreatography (ERCP), suitable treatment will be initiated without delay. Methods: To increase the number of exfoliated cells from the pancreatic duct, we devised a new technique, pancreatic duct lavage fluid (PDLF), following bronchoalveolar lavage fluid. The present paper reports the effectiveness of cytological examination using PDLF in the diagnosis of pancreatic carcinoma. We examined 18 pancreatic carcinoma cases. After the endoscopic retrograde pancreatography (ERP), PDLF was collected from a double‐lumen catheter inserted into the main pancreatic duct. Saline injected from the lumen for the injection, and PDLF was aspirated from the other lumen for the guidewire at the same time. The cytological examination was performed using PDLF. Results: Exfoliated cells were more frequently found in PDLF from all patients. In 15 cases (83%), cytological examination of PDLF revealed positive cytological results as the diagnosis of pancreatic carcinoma. Conclusion: Cytological examination using PDLF has a high sensitivity for detection of pancreatic carcinoma. The new examination, PDLF, is simple, safe and effective, so we expect PDLF to become widely popular.     

胆汁4种初级结合型胆汁酸的多因素判别对胆汁成石性的判断价值

本文运用二值回归判别法探讨了胆汁中4种初级结合型胆汁酸含量变化对胆汁成石性的判断价值。根据52例测试数据得出4因素二类判别函数:Y=0.0395X_1-0.0386X_2 0.0185X_3 O.0586X_4-1.0513。87例自、回代结果表明,该判别函数在判断符合率、错误率、假阳性率、假阴性率等诸方面均较使用1种初级结合型胆汁酸作为判别指标优越。
