Objective To study the etiology of primary intrahepatic stones. MethodsThe literatures in the recent years on the etiology of intrahepatic stone were revieved. Results The formation of intrahepatic stone mainly caused by bacteria infection, parasitic infestation, bile stasis, congenital anatomic abnormalities and immunoreaction of bile tract. Further investigation found that metabolic, low protein diet, environment and ethnic factors and gene mutation were considered to play important roles in the formation of the intrahepatic stone. Conclusion The formation of intrahepatic stone is complex and are result of multiple factors. It closely related to the infection and stasis of the bile duct.
ObjectiveTo investigate the effectiveness of epidermal growth factor receptor antagonist (AG-1478) on chronic proliferative cholangitis (CPC), so as to investigate new treatment approach for hepatolithiasis associated with CPC. MethodsForty-six SD rats were divided into 5 groups: CPC model group (n=10), only made models. AG-1478 treatment group (divided into 3 mg/kg， 6 mg/kg， and 12 mg/kg groups, n=10 per group), the common bile ducts in CPC animal model received an intralumenal administration of AG-1478 at the meantime of modeling, followed by intraperitoneal AG-1478 injection of 1.5 mg/(kg·d) for 7 days. Sham operation group (SO group, n=6). Subsequently, histopathological observation, immunohistochemistry, real time PCR， and Western blot were used to evaluate the mRNA expression and influence of AG-1478 on the hyperplasia （EGFR， ki-67， BrdU， collagen Ⅰ protein） and lithogenic potential (Mucin 5AC) of CPC. ResultsCompared with CPC model group, the expressions of EGFR, ki-67， and BrdU were obviously decreased in the AG-1478 treatment group. Also, the inhibition of hyperplasia of biliary epithelium and collagen fibers were confirmed by histopathological observation. Additionally, the expressions of Mucin 5AC mRNA and collagen Ⅰ protein remarkable decreased in the AG-1478 treatment group (Plt;0.05). Conclusions EGFR inhibitor (AG-1478) could shows inhibitory effectivenss on the CPC-mediated hyperplasia and lithogenic potential, and therefore holds promise as the new treatment approach for CPC.
目的 探讨胆源性肝脓肿的诊治方法。方法 对我院2000~2004年期间收治并确诊为胆源性肝脓肿的12例患者进行分析，在应用抗生素和全身支持的前提下，再依据其病变发生、发展的不同阶段采用不同手段治疗。结果 4例急性期患者中2例行急诊胆道引流手术后治愈，另2例转为亚急性期（脓肿融合期）； 6例亚急性期患者均经B超导向下行脓肿穿刺抽脓后注入抗生素治疗后治愈； 4例慢性期患者行脓肿切开引流后治愈。结论 本病在应用广谱抗生素（二联抗生素）和全身支持治疗的前提下，再根据病变不同时期采用不同方法治疗，可获得良好效果。
ObjectiveTo investigate the clinical application effect of descending hilar plate technology in laparoscopic heminephrectomy for intrahepatic bile duct calculus.MethodsThe clinical data of 40 patients with intrahepatic bile duct calculus who underwent laparoscopic heminephrectomy in our hospital from January 2015 to December 2019 were retrospectively analyzed. The patients were grouped according to different surgical procedures, 21 patients with Pringle method of total hepatic vascular exclusion were classified in the control group, and 19 patients with descending hilar plate technology of blood occlusion technology were classified in the observation group. The operation time, intraoperative bleeding volume, postoperative hospital stays, liver function recovery, and postoperative complications were compared between the two groups.ResultsThere was no statistically significant difference between the two groups in the intraoperative bleeding volume and operation time (P>0.05), but the postoperative hospital stays in the observation group shortened (P=0.025). The changes on the ALT, TB, and AST in the observation group was obvious than those of the control group (P<0.05). There was no statistically significant incidence between the two groups in the total incidence of complications (P=0.128).ConclusionsCompared with Pringle method of total hepatic vascular exclusion, descending hilar plate technology in laparoscopic heminephrectomy can fully expose the Glisson pedicles of the left and right livers, and it is convenient to implement hemihepatic blood flow occlusion. It has less damage to healthy side of the liver and quicker liver function recovery, and it can reduce postoperative complications and shorten postoperative hospital stay.
【Abstract】ObjectiveTo investigate the anatomic feature and special clinical manifestations of variant right intrahepatic bile duct draining into left hepatic bile duct near the umbilical portion. MethodsVariant right intrahepatic bile ducts joining into left hepatic bile ducts near the umbilical portions were identified through cholangiograms in 52 patients, who were included in this study. Their history, clinical process and operations were reviewed. ResultsThere were total 38 cases of intrahepatic gallstone in this group. High incidence of intrahepatic calculi was found in variant right intrahepatic bile ducts （23/38 cases, 60.52%） and left hepatic ducts （33/38 cases, 86.84%）. Most of these cases were accompanied with dilatation and stricture of bile ducts in these area. The gallstones in the variant right intrahepatic bile ducts were not detected in 8 cases (8/23) and the rate of residual gallstone was as high as 86.95%(20/23). Injury of variant right intrahepatic bile duct took place when left hepatectomy was performed in one case. ConclusionGallstone is very likely to be formed in the variant right intrahepatic bile duct due to derangement of bile hydrokinetics and compression of blood vessel. Special attention should be paid to the diagnosis and operation of this abnormity.
