Bronchobiliary fistula is a rare disease defined as an abnormal connection between the biliary tract and the bronchial tree. We report the successful surgical repair of bronchobiliary fistula. A 78-year-old man underwent surgery and several rounds of transcatheter arterial chemoembolization and radiofrequency ablation as treatment for hepatocellular carcinoma. He presented with greenish sputum and chronic cough for several months, and his symptoms did not resolve after endoscopic treatment. We performed lobectomy of the right lower lobe and omentopexy for bronchobiliary fistula under laparotomy and thoracotomy. The bronchobiliary fistula was successfully closed, and the bilious sputum disappeared after surgery.

Isolation and identification of anaerobic bacteria from blood cultures are still technically demanding procedures. Recently, with the use of gas liquid chromatography, the accuracy of identification is much improved. However, there has never been a satisfactory data analysis on anaerobic bacteremia in Korea. The authors evaluated both the clinical and the bacteriological data of 129 anaerobic bacteremias found at the Yonsei Medical Center during the period of 1973 to 1984. The most frequently isolated anaerobic bacteria were Bacteroides (52.7%), among which the major species was B. fragilis (38.7%). Incidence of anaerobic bacteremia by sex was 57% in male and 43% in female. Mortality was higg in groups below 1-year old and above 50-year old. The cause of death seemed closely correlated with the patient's age, general condition and the severity of the underlying disease. Various neoplasms were the most common (20%) underlying diseases predisposing the anaerobic bacteremia. Biliary tract was considered the most frequent route of infection in anaerobic bacteremia. The frequent clinical signs in anaerobic bacteremia were fever (65%), followed by liver function abnormality (29%), jaundice (20%) and hypotention(18%). When analysis of positive rate of blood culture was made on the patients from whom 4 cultures were done within 24 hours, it was found that 33% of the samples were positive. Isolation rate of anaerobic bacteria in thioglycollate medium was 83.8%, while it was 44% in Tryptic soy broth. Among the anaerobic bacteremia, 25.4% were polymicrobial infections with aerobic bacteria (92.5%), such as E. coli(33.3%). From these studies, it is concluded that B. fragilis is the most important causative organism in anaerobic bacteremia, with high fatality, particularly in those who have underlying diseases. The ports of entry are mainly biliary, gastrointestinal and female genital tract. Fever is the most frequent clinical sign. Single blood culture is not sufficient to detect all anaerobic bacteremia, therefore more cultures with optimal time interval are needed. The incidence of polymicrobial infection in anaerobic bacteremia is higher than that in overall bacteremia.

Objectives: The main goals of cancer treatment are improvement of quality of life and survival prolongation. There is a limitation to prolonging the survival time in hepatobiliary and pancreatic cancer. The purpose of this study was to evaluate the quality of life of hepatobiliary and pancreatic cancer patients who visited for traditional Korean cancer treatment. Methods: We evaluated the quality of life of 23 hepatobiliary and pancreatic cancer patients who visited for oriental medicine treatment at East-West Neo Medical Center from June to October of 2007. FACT-G (Functional Assessment Cancer Therapy-General), used in this study, is a scale for evaluation of QOL confirmed validity and reliability, popularly used in many countries to evaluate QOL of cancer patients. Results: The average age of enrolled patients was 57. There were 10 hepatocellular carcinoma patients, 7 pancreatic cancer patients, 6 biliary tract cancer patients. Twenty one patients were in stage IV and 20 patients had distant metastases. By Sasang constitution, Taeumin were 7, Soyangin were 8, and Soeumuin were 8. The baselines of FACT-G score in the first visit were from 34.33 to 85, and the mean score was 67.3. The mean score of FACT-G in hepatocellular carcinoma patients was 67.5, that of pancreatic cancer patients was 62.5, and that of biliary tract cancer patients was 71. Conclusions: This study is valuable as an initial QOL study of hepatobiliary and pancreatic cancer patients who visited an oriental medical clinic. We believe that consistent studies will be necessary to demonstrate oriental treatment-related quality of life with hepatobiliary and pancreatic cancer.

Objectives: Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. Methods: We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. Results: A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. Conclusions: The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor that often presents in early childhood, and it rarely occurs in adulthood. Aberrant development of the portal tract is a known cause of MHL. Although limited information is available on the natural course of MHL, malignant transformation has been reported in a few cases. Here, we report a case of a 26-year-old female with intrahepatic cholangiocarcinoma secondary to unresected MHL. The patient underwent resection of the hepatic mass, which was diagnosed as MHL at 2 years of age, due to an increase in mass size and a suspicion of malignant transformation during work-up. Histopathology confirmed intrahepatic adenosquamous carcinoma in the background of MHL, with a T2N0M0 pathological stage (stage II). The surgical margin was free from tumor cells. The patient fully recovered postoperatively and started receiving adjuvant chemotherapy. Previous case reports have only reported about the development of undifferentiated embryonal sarcoma or angiosarcoma as malignant transformation of MHL. Cases of other malignancies have not been published; however, it is difficult to rule out the occurrence of various malignancies related to the portal tract when considering the pathogenesis of the disease. To the best of our knowledge, this is the first case report of adenocarcinoma of bile duct origin secondary to MHL. This case report suggests that aggressive surgical management should be considered after the initial diagnosis of MHL.

We investigated the predictors of survival in patients with advanced BTC according to their baseline nutritional status estimated by the Nutritional Risk Screening (NRS)-2002. From September 2006 to July 2017, we reviewed the data of 601 inpatients with BTC. Data on demographic and clinical parameters was collected from electronic medical records, and overall survival (OS) and progression-free survival were analyzed using the Kaplan-Meier method and the stepwise Cox regression analysis. Patients with an NRS-2002 score of ≤ 2, 3, and ≥ 4 were respectively classified as "no risk," "moderate risk," "high risk." Following initial NRS-2002 score, 333 patients (55%) were classified as "no-risk," 109 patients (18%) as "moderate-risk," and 159 patients (27%) as "high-risk." Survival analysis demonstrated significant differences in the median OS: "no-risk": 12.6 months (95% confidence interval [CI], 11.5-13.7); "moderate-risk": 6.1 months (95% CI, 4.3-8.0); and "high-risk": 3.9 months (95% CI, 3.2-4.6) (p < 0.001). NRS-2002 score was an independent factor for OS (hazard ratio [HR], 1.616 for "moderate-risk", 95% CI, 1.288-2.027, p < 0.001; HR, 2.121 for "high-risk", 95% CI, 1.722-2.612, p < 0.001), along with liver metastasis, peritoneal seeding, white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, cholesterol, carcinoembryonic antigen, and carbohydrate antigen 19-9. In conclusion, baseline NRS-2002 is an appropriate method for discriminating those who are already malnourished and who have poor prognosis in advanced BTC patient. Significance of these results merit further validation to be integrated in the routine practice to improve quality of care in BTC patients.

Background/Aims: Advanced pancreatic and biliary tract cancers can invade the duodenum and cause duodenal hemorrhagic stenosis. This study aimed to evaluate the efficacy of covered self-expandable metal stents in the treatment of cancer-related duodenal hemorrhage with stenosis. Methods: Between January 2014 and December 2016, metal stents were placed in 51 patients with duodenal stenosis. Among these patients, a self-expandable covered metal stent was endoscopically placed in 10 patients with hemorrhagic duodenal stenosis caused by pancreatobiliary cancer progression. We retrospectively analyzed the therapeutic efficacy of the stents by evaluating the technical and clinical success rates based on successful stent placement, degree of oral intake, hemostasis, stent patency, and overall survival. Results: The technical and clinical success rates were 100%. All 10 patients achieved a gastric outlet obstruction scoring system score of three within two weeks after the procedure and had no recurrence of melena. The median stent patency duration and overall survival after stent placement were 52 days (range, 20-220 days) and 66.5 days (range, 31-220 days), respectively. Conclusions: Endoscopic placement of a covered metal stent for hemorrhagic duodenal stenosis associated with pancreatic or biliary tract cancer resulted in duodenal hemostasis, recanalization, and improved quality of life.

Purpose of this paper is to extend help for clinical application in balloon cholangiography on patients who have undergone endoscopic sphincterotomy, impacted stones of intrahepatic duct, and missed bile duct because of other diseases in operating endoscopic retrograde cholangiopancreatography. This study was done for the patients who had clinical signs of biliary diseases from January to December In 1996. We studied 45 patients who had endoscopic sphincterotomy, re-examination after interventional treatment of the endoscopic retrograde cholangiopancreatography, and uncertain diagnosis due to common bile duct and intrahepatic duct those are not filled with contrast media. Balloon cholangiography was performed in case of uncertain diagnosis while operating endoscopic retrograde cholangiopancreatography. First of all, we insert balloon catheter Into the working channel of treatment jejunofiberscope and remove treatment Jejunofiberscope after ballooning, and lastly take biliary tract X-ray after Injection and changing position of patient. The results of this study were as follows. (1) In classification of diseases, stones of gall bladder, those of common bile duct, and those of intrahepatic duct were 30 cases, fistula was 1 case. (2) In total cases of 45, only diagnosis were 25 cases, interventional treatment were 20 cases. (3) In case of interventional treatment, endoscopic sphincterotomy and endoscopic nasobiliary drainage, and stone removal were about the same, 7, 7, 6 respectively. Balloon cholangiography will be useful to prevent patients from having repeated and unnecessary studies for the cases above explained. It is considered that this study will be useful for clinical application in terms of reducing medical expenses, pain while examination, and consultation hours.
