腹腔镜胆囊切除术前超声内镜检查胆总管必要性的探讨

目的 探讨腹腔镜胆囊切除（laparoscopic cholecystectomy,LC）术前超声内镜（endoscopic ultrasonography,EUS）检查胆总管的临床价值。方法 对25例术前经腹超声检查诊断胆囊结石,胆总管内径〉0.7 cm可疑胆总管梗阻的患者进行EUS检查,并与手术结果或内镜十二指肠乳头切开术（endoscopic sphincterotomy,EST）取石结果进行比较。结果 EUS对于胆总管病变诊断的敏感性、准确性和阴性预测值[100%（17/17）、92%（23/25）、100%（6/6）]均优于经腹超声[35%（6/17）、56%（14/25）、42%（8/19）]（P=0.000,0.008,0.020）。结论EUS对胆总管病变诊断优于经腹超声检查,可作为术前常规检查,特别是当胆总管内径〉1.0 cm时,EUS应作为术前必检项目。     

肝移植术后缺血型胆道病变的再移植治疗策略

目的探讨肝移植术后缺血型胆道病变的再移植的指征、手术时机的选择及免疫治疗策略。方法回顾性分析我中心自1999年7月至2007年2月10例肝移植术后缺血型胆道病变再移植治疗的病例。供肝植入均采用改良背驮式原位肝移植术,手术当天及第四天给予IL-2受体拮抗剂（舒莱）,术中不用激素冲击,术后采用他克莫司（FK506）,麦考酚酸酯（MMF）和激素（Pred）的常规三联或FK506和MMF两联免疫抑制治疗方案。结果10例病人中8例术后肝功能恢复良好,顺利痊愈出院,最长已存活42个月。2例死亡,分别于术后34、69 d死于严重的混合感染。术前MELD小于25分的7例患者无一例死亡,术前MELD大于25分的3例患者中2例死亡。结论肝移植术后发生缺血型胆道病变行再次肝移植是有效的治疗方法。术前对患者病情的准确评估,尽可能在MELD评分小于25分时进行再次肝移植治疗,有助于提高再移植的疗效。

Bone disease in primary biliary cirrhosis: Lack of association with distal renal tubular acidosis

Background and Aims: Primary biliary cirrhosis (PBC) might be complicated by osteoporosis, whose etiology remains unknown but seems to be multifactorial. Prevalence rates of 30% to 60% for distal renal tubular acidosis (DRTA) have been reported in PBC patients, generally as incomplete DRTA. Although it is undisputed that a reduced bone mineral density (BMD) is the expected outcome among patients who have been suffering from longstanding chronic metabolic acidosis, it is unclear if incomplete DRTA is also associated with metabolic bone disease in PBC patients. The present study was undertaken to compare the BMD of PBC patients with and without DRTA.
Methods: The BMD of 23 PBC patients (11 with DRTA and 12 without), all with normal clearance of creatinine, was assessed by dual energy radiograph absorptiometry. The diagnosis of DRTA was made if the urine pH was above 5.4 in all samples after the oral acid overload, showing tubular inability to acidify urine in the presence of test-induced systemic metabolic acidosis.
Results: Densitometric signs of osteoporosis were found in 82% of DRTA cases and in 83% of patients without DRTA (difference not significant). There were no significant differences in BMD measurement, T and Z scores of patients with and without DRTA.
Conclusions: The present study could not support a correlation between the presence of DRTA and the bone loss observed in PBC patients.     

NASOGALLBLADDER DRAINAGE FOR MIRIZZI’S SYNDROME

The authors experienced a case of Mirizzi’s syndrome successfully treated with endoscopic nasogallbladder drainage (ENGBD). The patient was a 63‐year‐old man. He was admitted with abdominal pain and jaundice. Laboratory data indicated leukocytosis and elevation of serum bilirubin level. Abdominal ultrasound showed marked swelling of gallbladder and debris in the gallbladder, therefore, the authors strongly suspected Mirizzi’s syndrome. He had past history of acute myocardial infarction and treated with anticoagulation therapy. Then, the authors couldn’t perform surgical removal or percutaneous transhepatic drainage, and tried endoscopic transpapillary drainage. Endoscopic retrograde cholangiopancreatography revealed smooth stricture in the superior portion of common bile duct and occlusion of the cystic duct, and ENGBD was then performed. After ENGBD, his complaints, laboratory data, swelling of gallbladder and stricture of common bile duct were all remarkably improved.     

肝移植术后胆道并发症的介入治疗

目的 探讨原位肝移植术后胆道并发症的介入治疗疗效。方法 回顾性分析我院2002年6月至2005年9月诊治的173例原位肝移植患者的临床资料。结果 术后出现胆道并发症14例（8．1％），其中胆管狭窄6例．胆管狭窄合并胆漏1例，胆泥淤积或结石3例，肝断面胆漏2例（劈离式肝移植患者），T管拔除后胆漏1例，Oddi括约肌功能失常1例。除1例胆道狭窄再次行肝移植，因发生严重感染导致肝功能衰竭死亡外．其余患者经介入治疗均获得满意的效果。结论 介入治疗是诊断和治疗肝移植术后胆道并发症的首选方法。

Laparoscopic choledochotomy with primary closure

Background: Thirty-three patients were candidates for laparoscopic choledochotomy. The indications for this operation are described. Methods: The procedure was completed 32 times (97%). We had 29 successful common bile duct (CBD) clearances, three negative explorations, and one failed clearance which needed to be converted to laparotomy. All the completed procedures ended with primary closure of the main duct. Median duration of surgery was 180 min (range 100–300), including three associated laparoscopic procedures. Results: There were three postoperative complications (9.4%), none major. Average postoperative hospital stay was 7.1 days (range 4–14). In May–June 1995 we controlled 31 out of the 32 consecutive patients (one patient was lost to follow-up) who had a successful laparoscopic choledochotomy from October 1991 to December 1994. Median follow-up was 22 months (range 5–44). Besides clinical control, 23 patients also had ultrasound (US) controls and 24 had blood tests. Eleven had intravenous cholangiotomography. Two patients died 11 and 22 months after the operation for unrelated causes and without biliary symptoms. Two patients had umbilical hernias. One had a small residual asymptomatic stone, which was removed endoscopically. None had signs of postoperative CBD stricture. At US, CBD was ≤7 mm in 15 patients, 8–10 mm in four patients, and 10–12 mm in three patients. The last group had preoperative CBD dilation, too. We could compare preoperative and postoperative CBD diameters in 22 patients: 11 had no change; in nine it decreased; and two had a slight increase (8–10 mm). Conclusions: We conclude that laparoscopic choledochotomy with primary closure is a very good operation: It has a high success rate and low morbidity. Mortality is nil so far. Medium-term results are very positive: We had no CBD stricture and only one case of asymptomatic residual stone, which could have been avoided. Our results suggest that intraductal biliary drainage is useless, and its specific complications are well known. Received: 20 October 1995/Accepted: 28 February 1996     

胸导管引流对慢性哮喘病人外周血淋巴细胞内环核苷酸代谢的影响

观察7例慢性哮喘病人胸导管引流治疗前后外周血淋巴细胞内 cAMp/cGMP 值的变化。结果发现,慢性哮喘病人外周血淋巴细胞内 cAMP/cGMP 的值较正常人低(P<0.001);胸导管引流治疗后,哮喘病人外周血淋巴细胞内 cAMP/cGMP 值较治疗前升高(P<0.01)。提示,慢性哮喘病人外周血淋巴细胞功能异常、活性增强,这可能是哮喘发病的重要原因之一。胸导管引流引起的免疫抑制作用,一个重要的机理就是影响淋巴细胞内环核苷酸的代谢,而使淋巴细胞的活性降低,这可能也是胸导管引流治疗慢性哮喘的机理之一。     

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。
