Objective To evaluate the methodological and reporting quality of randomized controlled trials involving traditional Chinese medicine in the treatment of cholelithiasis. Methods We searched CNKI (1994 to 2007), CMCC (1994 to 2007), VIP (1989 to 2007), MEDLINE (1966 to April 2007) and The Cochrane Library (Issue 4, 2006). Data from randomized controlled trials (RCTs) and quasi-RCTs were extracted by two reviewers independently. The methodological quality of included trials was assessed by using the quality assessment criteria recommended by The Cochrane Collaboration, and the reporting quality was assessed by using the CONSORT for TCM checklist. Results Seventeen studies including 16 RCTs and one quasi-RCT were included. The methodological and reporting qualities of included studies were generally low. All studies were graded C. The highest score evaluated by the CONSORT for TCM checklist was 18. Conclusion The quality of RCTs and quasi-RCTs involving traditional Chinese medicine for cholelithiasis is generally low, with a high risk of biases. The reporting of these trials is also incomplete, which would affect a reader’s understanding and evaluation of the validity, importance and applicability of the study results. Therefore, new randomized controlled trials of high quality are required to provide reliable evidence.
肝脏移植、心脏移植及肾脏移植等已广泛开展,大批受者长期存活。本文现就这组特殊人群在移植术后患胆道结石病的机理及其处理原则介绍如下。1器官移植受体胆石病的发生机理肝移植术后胆管结石与胆泥形成并引起胆道梗阻可随时发生。除了明确的结石外,胆泥形成胆管铸形并广泛分布于肝内胆管也有报道。胆管粘膜损害、胆管梗阻、移植肝的冷、热缺血、感染及胆固醇过饱和等都在胆管结石形成过程中发挥作用,但胆管梗阻可能是肝移植术后胆管结石形成的最重要因素[1]。胆管结石和胆泥形成的患者,绝大多数都伴有胆管狭窄,这个狭窄可以发生在胆管胆管吻合口和胆管空肠吻合口,也可发生在非吻合口处的胆管。胆管内异物如T型管或内支撑管也可作为结石形成的核心。除了这些引起胆汁淤积的物理学原因外,环孢素A(CsA)在胆石发生中也起了作用[2]: 它可抑制胆汁分泌,促进胆汁淤积,而FK506(普乐可复)似乎没有这方面的副作用。此外,肝移植受者胆汁中胆固醇呈过饱和状态,且T管引流及胆酸池的减少还加重这种状态。目前还不清楚胆道重建方式对胆道结石形成有没有影响。但从理论上讲,胆肠吻合会增加肠源性细菌进入胆道的机会,从而导致胆红素去结合化,并进一步形成色素石。但到底是胆管对端吻合还是胆肠吻合后更易形成结石,目前尚无详尽研究。
目的:探讨腹腔镜胆囊切除术(LC)与内镜十二指肠乳头括约肌切开术(EST)联合应用治疗胆囊结石合并胆总管结石的临床效果。方法:回顾性分析我院开展的LC联合EST治疗胆囊结石合并胆总管结石76例,其中56例先行EST后行LC,20例先行LC后行ERCP/EST。结果:本组全部治愈,先行EST组56例,3例并发胰腺炎,3例出血,2例再发胆总管结石,先行LC组20例行EST11例,6例取石后未做括约肌切开,3例结石自行掉入肠道,1例出现胆道感染,1例胰腺炎,无出血及穿孔。结论:内镜治疗胆囊结石继发胆总管结石具有创伤小、效果好、并发症少、恢复快的的特点;先作EST可解除胆道梗阻、减轻炎症,并为LC创造条件,选择性先行LC后可减轻创伤,甚至不必做EST。
目的:探讨胆石症再次手术的原因及预防措施。方法:对我院过去5年收治的134例胆石症再次手术病例的临床资料进行回顾性分析。结果:胆石症再次手术主要原因为结石残留或复发(86.57%),医源性胆管损伤(4.48%),拔除T管后胆汁性腹膜炎(4.48%),残留胆囊炎伴结石(2.99%),胆肠吻合口狭窄伴结石(1.49%)等。再次手术方式以胆总管切开取石胆道镜检查取石“T”形管引流术、胆总管十二指肠侧侧吻合术,肝胆管空肠Roux-en-Y吻合术,肝叶段切除,残留胆囊切除术为主。本组患者痊愈131例,死亡3例,死亡率2.29%,术后残石率5.17%.结论:对于胆石症,无论是首次手术还是多次手术,均应做好术前检查,制定周密的手术计划,利用胆道外科和肝脏外科技术,努力贯彻去除病灶,解除梗阻,通畅引流三原则,力争将残石率、复发率、再手术率降低到最低限度。
目的 探讨对Mirizzi综合征实施临床合理有效的手术方法。方法 自1990年1月至2003年12月期间,我院采用经肝放置胆道支撑引流管治疗Ⅱ、Ⅲ型Mirizzi综合征21例,胆道支撑引流管放置6个月以上,并行胆道造影检查。结果 所有患者恢复良好,胆道造影检查见胆道通畅后拔除支撑引流管,随访2~10年,无并发症发生。结论 经肝放置胆道支撑引流管治疗Ⅱ、Ⅲ型Mirizzi综合征,是保持胆道生理功能完整的有效方法。
Objective To evaluate the effectiveness and safety of Chinese medicine treatment of cholelithiasis. Methods We searched electronic databases including MEDLINE (1966 to Feb. 2009), EMbase (1974 to Feb. 2009), The Cochrane Library (Issue 4, 2008), Chinese Biomedical Literature Database (CBM, 1978 to Feb. 2009), CJFD (CNKI, 1994 to Feb. 2009), the Chinese Scientific and Technical Journals database (VIP, 1989 to Feb. 2009), and a database of Chinese biomedical journals (CMCC, 1994 to Feb. 2009). At the same time, we searched references of the included studies. Metaanalysis was performed using RevMan 5 if there was no significant heterogeneity. We described the date which could not be combined. Results A total of 18 randomized controlled trials involving 2 276 patients were included. According to measurement indicators and interventions, subgroup analysis was performed. Efficacy was reported in 10 studies, which showed that part of proprietary Chinese medicines had a higher efficiency for cholelithiasis. Gallbladder emptying index and the trend of bile into the stone were compared in 5 studies, suggesting that the bile of proprietary Chinese medicines reduced the stone index, which eased the bile tendency to rock. Three studies reported the rate of cholecystokinin. Metaanalysis results suggested that the difference was significant. Two studies reported adverse drug reactions (ADRs), such as epigastric discomfort and diarrhea. Most ADRs were slight, and could be self relieved. Conclusion Results suggest that Chinese medicines produce effects on clinical symptoms of cholelithiasis, gallbladder function and reduce the trend of bile into stones. However, the therapeutic effects for long-term are rarely reported. The conclusion needs further verification due to low methodological quality and apparent heterogeneity.
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.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
Thirty-six partial hepatectomies for patients with symptomatic intrahepatic stones is reported.Partial liver resection should be done when the liver containing strictrue(s),dilated ducts and stones.Meanwhile,additional procedures should be performed togather with partial hepatectomy,i,e,common duct exploration and drainage,cholangiotomy and cholangioplanty,and cholangeoenterostomy,according to the location of stones and ductal strictures.Postoperative long-term follow-up in this series showed that the results of 86.2% of patients were satiffactory.Partial hepatectomy can be considered as a better treatment of choice for the stones confined to one segment or lobe of liver or combined with multiple strictures of ducts.
Objective To explore the effects of bile from patients with cholecystolithiasis on the growth of human gallbladder carcinoma cells GBC-SD and the potential correlation between cholecystolithiasis and gallbladder carcinoma. Methods Cholecystolithiasis bile (CB) and normal bile (NB) specimens were used for this study. The proliferative effects of bile were measured by methabenzthiazuron (MTT) assay and cell cycle and apoptosis were analyzed by flow cytometry. Results CB can significantly promote the proliferation of GBC-SD cells, GBC-SD proliferative index increased significantly after treated with 1% CB for 48 h (P<0.05).The Sphase fraction of CB 〔(49.26±8.07)%〕 increased remarkably (P<0.05) compared with that of NB 〔(25.54±6.57)%〕, and the CB percentage of G0/G1 phase 〔(40.59±9.12)%〕 decreased remarkably (P<0.05) compared with NB 〔(60.64±13.42)〕%. Conclusion CB can promote the proliferation of human gallbladder carcinoma GBC-SD cells.
