Objective To investigate the prevention and treatment strategy of bile duct injury (BDI) in laparoscopic cholecystectomy (LC). MethodsLatest progress was reviewed based on recent documents and the experience on BDI in LC in our department. ResultsWith the popularity of LC, BDI in LC is increasing. The reasons include illegibility and variability of local anatomy in gallbladder trigone,injury caused by galvanothermy, as well as operator’s overconfidence. In order to prevent BDI, we should apply more blunt dissection, not to use electrocogulation if possible and to study local anatomy and its variance clearly. The common bile duct and common hepatic duct should be clearly identified. Intraoperative cholangiography, laparoscopic ultrasonography and hepatobiliary scintigraphy are selections as necessary.The treatment of BDI depends on the type of BDI and its site and local condition.The treatment includes end to end anastomosis, repairing the defect, choledochoduodenostomy, RouxenY choledochojejunostomy and so on. T tube should be maintained in place for more than half a year after operation.Conclusion The key to improve the prognosis of BDI is prevention and treatment in proper time and in correct way.
ObjectiveTo summarize the research advancement of peroxisome proliferator-activated receptor γ (PPARγ) agonists inhibiting transforming growth factor-β (TGF-β)-induced organ fibrosis. MethodsThe related literatures on PPARγ agonists inhibiting TGF-β-induced organ fibrosis were reviewed. ResultsTGF-β was a major fibrosispromoting cytokine, which could promote a variety of organ fibrosis. PPARγ agonists could effectively block TGFβ signal transduction, and then suppressed organ fibrosis well. ConclusionsThe main antifibrotic mechanism of PPARγ agonists is to inhibit TGF-β signal transduction. The studies on this mechanism will help promoting the clinical application of PPARγ agonists, and provide a new way of the treatment for organ fibrosis.
目的 探讨脾占位性病变的临床诊断特点和治疗对策。方法 回顾性分析68例脾占位性病变患者的临床资料。结果 超声和CT是诊断脾占位性病变的主要方法。68例脾占位性病变中良性48例，恶性20例。手术治疗47例，其中脾切除37例，脾切除加胰尾切除2例，脾部分切除3例，脾切除加脾窝引流4例，单纯脾囊肿去顶减压1例。1例脾脓肿行脾切除术后发生肺部感染，经抗感染治疗后痊愈； 1例脾脓肿行脾切除术后，发生脾窝脓肿，感染严重，被迫再次开腹行脓肿引流术，其余良性病变经手术治疗后效果好； 恶性病变术后效果差。结论 脾占位性病变良性多见，恶性少见； 影像学检查是诊断脾占位性病变的主要手段。脾切除对成年人是一种有效的治疗方法，良性预后好，恶性预后差； 对儿童、青少年脾良性病变，脾部分切除是一种很好的选择。
