Metastasis to the gallbladder:A single-center experience of 20 cases in South Korea

引用

World Journal of Gastroenterology 2009年第38期15卷 4806-4809页

作者： Won Jae Yoon Yong Bum Yoon Youn Joo Kim ji kon ryu Yong-Tae Kim Department of Internal Medicine Seoul National University College of Medicine Department of Internal Medicine Korea Cancer Center Hospital

AIM： To evaluate the clinicopathologic characteristics of patients with metastases to the gallbladder （MGBs）. METHODS： We performed a single-center retrospective study of 20 patients with MGBs diagnosed pathologically from 1999 to 2007. RESULTS： Among 417 gallbladder （GB） malignancies, 20 （4.8%） were MGBs. The primary malignancies originated from the stomach （n = 8）, colorectum （n = 3）, liver （n = 2）, kidney （n = 2）, skin （n = 2）, extrahepatic bile duct （n = 1）, uterine cervix （n = 1）, and appendix （n = 1）. Twelve patients were diagnosed metachronously, presenting with cholecystitis （n = 4）, abdominal pain （n = 2）, jaundice （n = 1）, weight loss （n = 1）, and serum CA 19-9 elevation （n = 1）; five patients were asymptomatic. The median survival after the diagnosis of MGB was 8.7 mo. On Cox regression analysis, R0 resection was the only factor associated with a prolonged survival [hazard ratio （HR）： 0.01, P = 0.002]; presentation with cholecystitis was associated with poor survival （HR： 463.27, P = 0.006）. CONCLUSION： MGBs accounted for 4.8% of all pathologically diagnosed GB malignancies. The most common origin was the stomach. The median survival of MGI3 was 8.7 mo.

Optimal biliary drainage for inoperable Klatskin's tumor based on Bismuth type

引用

World Journal of Gastroenterology 2007年第29期13卷 3948-3955页

作者： Sang Hyub Lee Joo Kyung Park Won Jae Yoon Jun Kyu Lee ji kon ryu Yong Bum Yoon Yong-Tae Kim Department of Internal Medicine and Liver Research Institute Seoul National University College of Medicine Seoul South Korea

AIM： To investigate differences in the effects of biliary drainage procedures in patients with inoperable Klatskin＇s tumor based on Bismuth type, considering endoscopic retrograde biliary drainage （ERBD）, external percutaneous transhepatic biliary drainage （EPTBD） and internal biliary stenting via the PTBD tract （IPTBD）. METHODS： The initial success rate, cumulative patency rate, and complication rate were compared retrospectively, according to the Bismuth type and ERBD, EPTBD, and IPTBD. Patency was defined as the duration for adequate initial bile drainage or to the point of the patient＇s death associated with inadequate drainage. RESULTS： One hundred thirty-four patients （93 men, 41 women; 21 Bismuth type Ⅱ, 47Ⅲ, 66 Ⅳ; 34 ERBD, 66 EPTBD, 34 IPTBD） were recruited. There were no differences in demographics among the groups. Adequate initial relief of jaundice was achieved in 91% of patients without a significant difference in the results among different procedures or Bismuth types. The cumulative patency rates for ERBD and IPTBD were better than those for EPTBD with Bismuth type Ⅲ. IPTBD provided an excellent response for Bismuth type IV. However, there was no difference in the patency rate among drainage procedures for Bismuth type Ⅱ. Procedure-related cholangitis occurred less frequently with EPTBD than with ERBD and IPTBD. CONCLUSION： ERBD is recommended as the firstline drainage procedure for the palliation of jaundice in patients with inoperable Klatskin＇s tumor of Bismuth type Ⅱ or Ⅲ, but IPTBD is the best option for Bismuth type Ⅳ.

Risk factors of organ failure in cholangitis with bacteriobilia

AIM: To identify the risk factors for organ failure(OF) in cholangitis with ***: This study included 182 patients with acute cholangitis who underwent percutaneous transhepatic biliary drainage between January 2005 and April 2013. We conducted a retrospective analysis of comprehensive clinical and laboratory ***: There were 24 cases(13.2%) of OF and five deaths(2.7%). Bile culture was positive for microbial growth in 130 out of 138(94.2%) patients. In multivariate analysis of 130 patients with positivebile cultures, significant predictive factors for OF were the presence of extended-spectrum beta-lactamase(ESBL) organisms in blood cultures, pre-existing renal dysfunction, and choledocholithiasis as an etiology, with odds ratios of 15.376, 6.319, and 3.573, respectively. We developed a scoring system with a regression coefficient of each significant variable. The OF score was calculated using the following equation:(2.7 × ESBL organisms in blood cultures) +(1.8 × pre-existing renal dysfunction) +(1.3 × choledocholithiasis). This scoring system for predicting OF was highly specific(99.1%) and had a positive predictive value of 86.2%.CONCLUSION: ESBL organisms in blood cultures, preexisting renal dysfunction, and choledocholithiasis are risk factors for OF in cholangitis with bacteriobilia. The OF scoring system may aid clinicians to identify a poor prognosis group.

AIM： To investigate prevalence of C/onorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea. METHODS： Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire. RESULTS： Of 3080 patients with gastrointestinal diseases, 396 （12.9%） had clonorchiasis and 1140 patients （37.2%） had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 （20.9%） patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than nonnfected patients [34/396 （8.6%） vs 145/2684 （5.4%）, P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation （P = 0.008）. Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis. CONCLUSION： Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.

Electrochemical performance of all-solid lithium ion batteries with a polyaniline film cathode

引用

Journal of Energy Chemistry 2016年第1期25卷 93-100页

作者： ji-Woo Oh Rye-Gyeong Oh Yongku Kang Kwang-Sun ryu Department of Chemistry University of Ulsan Advanced Materials Divisions Korea Research Institute of Chemical Technology

We have prepared a high-density polyaniline（PANI） paste（50 mg/m L）, with similar physical properties to those of paints or pigments. The synthesis of PANI is confirmed by Fourier transform infrared（FT-IR） spectroscopy. The morphologies of PANI, doped PANI, and doped PANI paste are confirmed by scanning electron microscopy（SEM）. Particles of doped PANI paste are approximately 40–50 nm in diameter, with a uniform and cubic shape. The electrochemical performances of doped PANI paste using both liquid and solid polymer electrolytes have been measured by galvanostatic charge and discharge process. The cell fabricated with doped PANI paste and the solid polymer electrolyte exhibits a discharge capacity of ～87 μAh/cm2（64.0 m Ah/g） at the second cycle and～67 μAh/cm2（50.1 m Ah/g） at the 100 th cycle.
