  • To investigate the effect of intravenous ethanol administration on pancreatic exocrine secretion, we measured volume and protein amount in pancreatic juice and assayed amylase activity and phospholipase $A_2$ activity in pancreatic fragments and serum. Acute pancreatitis induced by obstruction of common bile-pancreatic duct (CBPD) and caerulein infusion (5 $\mu\textrm{g}$/kg/hr) showed typical characteristics, such as hyperamylasemia and pancreatic edema and increase of phospholipase $A_2$ activity in pancreatic fragments and serum. Intravenous ethanol infusion (50 mg/kg/hr) significantly stimulated pancreatic exocrine secretion, but such a stimulatory effect of ethanol disappeared at dose of 100 mg/kg/hr without typical symptoms of acute pancreatitis. In microscopic examination, there were no typical changes of edematous pancreatitis in ethanol administrated rats. These results suggest that acute ethanol administration has dual effect on exocrine pancreatic secretion: low dose of ethanol (50 mg/kg/hr) stimulates pancreatic exocrine secretion, whereas high dose of ethanol (100 mg/kg/hr) does not without typical changes of edematous pancreatitis.

  • Multiple primary cancer is defined as the discrete primary cancers in an individual originating in different sites or tissues. Billroth, in 1869, first reported the occurrence of different primary malignant cancers in the same patient. Because early diagnosis and treatment are key to good survival and cure rates, clinicians should be more aware of the possibility of multiple primary cancers in an individual patient with malignant tumor. The authors recently experienced a case of fifth primary cancer, their sites of origin were lung, glottis, lymph node, supraglottis, common bile duct. We report this case with a brief review of literatures.

  • A 55-year-old man was admitted to the hospital for jaundice. Computed tomography (CT) scans showed a diffuse mass in the pancreas and peripancreatic area, with infiltration to of the whole pancreas, and overall reduced enhancement compared to normal pancreas. Esophagogastroduodenoscopy revealed elevated mucosal lesion covered hyperemic mucosa at duodenal bulb and ulcerative lesion at body of stomach. Endoscopic ultrasonography revealed an irregular mass with unclear boundaries was observed within the pancreas. Abrupt narrowing of mid to distal common bile duct was seen and the stricture was caused by compression of pancreatic mass. Plastic stent was inserted and clinical improvement was achieved including resolution of jaundice. The patient is currently being treated with combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. We report a case of primary pancreatic lymphoma presenting with obstructive jaundice.

  • There is compelling evidence that chronic inflammation predisposes to biliary tract cancer. Previously we found that aspirin use and variants in the PTGS2 gene, both of which are closely linked to inflammation, were associated with biliary tract cancer risk in a population-based study in China. To test the inflammation hypothesis further, we examined the associations of variants in 20 genes involved in the inflammation pathway with risk of biliary tract cancer and stones in a large population-based case-control study in Shanghai, China. We genotyped 56 single nucleotide polymorphisms (SNPs)from 20 inflammation genes in 411 biliary tract cancer cases (237 gallbladder cancers, 127 extrahepatic bile duct cancers, and 47 ampullary cancers), 895 subjects with biliary stones, and 786 population controls. Unconditional logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (Cls) for the association of individual SNPs and haplotypes with biliary stones and biliary tract cancer risk. Of the 56 SNPs examined, 20 showed some associations with biliary cancer and stones. Specifically, variants of the IL8, IL8RB, RNASEL, TGF-beta, and TNF-alpha genes were associated with gallstone risk, while variants in the IL1A, IL10, VEGF, and RNASEL genes were associated with gallbladder cancer risk. Adjustment for multiple comparisons did not materially change these results. Of the 10 genes with multiple SNPs, we inferred halotypes; only one haplotype in the IL8RBgene was associated with gallstones. The haplotype frequency was significantly different between bile dict cancer cases and control (p=0.007). A haplotype comprising 3 SNPs in the IL8RB gene (rs2230054, rs1126579, rs1126580) was associated with a 54% increased risk of bile duct stones (95% CI 1.14-2.07, p=0.02), relative to the most frequent haplotype. In summary, common variants in immune-related genes influencing inflammatory responeses were associated with gallstones and biliary tract cancer, lending further support to the role of inflammation in the pathogenesis of biliary stones and biliary tract cancer. Future larger studies with more complete gene coverage are needed to confirm these results.

  • When jaundice persists for more than 14 days postnatally, the early diagnosis of surgical jaundice is important for the prognosis in extrahepatic biliary atresia after draining procedure. The role of diagnostic laparoscopy to differenctiate medical causes of jaundice from biliary atresia is evaluated in this report. Four patients with prolonged jaundice have been included in this study. When the gallbladder was not visualized we proceeded to laparotomy. In patients with enlarged gallbladder visualized at laparoscopy, laparoscopic guided cholangiogram was performed, and laparoscopic liver biopsy was done for those who had a patent biliary tree. Two patients had small atretic gallbladder and underwent a Kasai hepato-portoenterostomy. One patients showed a patent gallbladder and common bile duct with atresia of the common hepatic and intrahepatic ducts, and they underwent a Kasai hepatic-portoenterostomy. One patient showed an enlarged gallbladder and laparoscopic-guided cholangiogram were normal. Laparoscopic liver biopsy was performed. There were no complications. Laparoscopy with laparoscopic-guided cholangiogram may be a valuable method in accurate and earlier diagnosis in an infant with prolonged jaundice.

  • 담관 결석은 동통뿐만 아니라 황달이나 담도염 또는 췌장염 등을 유발할 수 있다. 결석에 대한 내시경적 제거가 실패할 경우 체외충격파쇄석술이 요구될 수 있는데, 이 논문은 담관 결석환자에 대한 체외충격파쇄석술 적용에 있어 보다 더 적절한 선택 기준을 정하는데 도움을 주기 위함이다. 총담관 결석 환자 중 기계적 쇄석술을 포함한 내시경적 제거에 실패한 46명이 체외충격파쇄석술을 받았다. 46명 모두 체외충격파쇄석술 전에 내시경적 유두괄약근 절개술을 받았으며, 경비담도배액관의 삽입이 이루어 졌다. 사용된 쇄석기는 초음파 유도하에 결석을 포착하는 시스템으로 spark-gap type이였다. 쇄석 후 추가적인 내시경적 제거술이 이루어 졌으며, 결석이 완전 제거된 경우는 89.1%(41/46)였으며, 자연 배출된 경우는 6.5%였다. 쇄석 후 결석제거율은 결석의 수(단일: 82.8%, 둘-셋: 100%, 넷 이상: 100%)와 크기(33 mm 미만: 92.9%, 33 mm 이상: 83.3%)에서는 큰 차이가 없었으나, 결석들의 장축 길이 합과 결석이 위치하지 않는 부분의 총담관 길이 합을 비교하였을 때 완전 제거된 경우와 그렇지 않은 경우의 비가 1:1.4와 1:1.1, 그리고 가장 큰 결석의 직경과 결석하방의 총담관 직경을 비교한 경우는 그 비가 1:0.9와 1:0.4로 의미 있는 차이를 보였다. 결론적으로, 결석의 수나 크기보다는 총담관 내에 분쇄된 결석이 충분히 움직여 바스켓으로 포획될 수 있는 공간이 있을 경우에 체외충격파쇄석술 적용이 상당히 유용하나 그렇지 않은 경우는 경피적 담도경을 이용한 제거가 유용할 것으로 보인다.

  • In order to evaluate the scintigraphic features of choledochal cyst and these diagnostic value, authors investigated the findings of fourteen patients with choledochal cyst undergone hepatobiliary scan with $^{99m}Tc$-DISIDA before surgery. Five cases demonstrated the decreased hepatic uptake at 5-minute image of which four cases revealed severe jaundice. Seven cases demonstrated visualization of the cystic dilated common bile duct within 1 hour after injection. Two cases showed the cyst activity between 1 and 12 hours, but the cyst activity was not visible in five cases. Nonvisualization of the gall bladder was noted in ten cases, while four cases demonstrated visualization of the gall bladder within 1 hour. The time of visualization of gut activity was variably delayed. The intestinal activity was found in three cases within 1 hour and appeared in three cases between 1 and 2 hours and eight cases showed no visible gut activity. In four cases, intrahepatic ductal prominence was visible on the scintigram. Seven cases showed early and persistent accumulation of tracer in the common bile duct. Three cases showed persistent photon-deficient area in the gall bladder region. Two cases showed early photon-deficient area around gall bladder region with progressive accumulation of tracer in the same region. Two cases showed no evidence of activity in the biliary tract but noted late excretion into the small intestine. We concluded that hepatobiliary scan using $^{99m}Tc$-DISIDA is a noninvasive test useful in the evaluation and the diagnosis of choledochal cyst.

  • Two dogs were referred to Veterinary Medical Center, Chungbuk National University with the clinical signs of vomiting, diarrhea, anorexia, and jaundice. Both dogs were diagnosed as extrahepatic biliary tract obstruction(EHBO) with concurrent pancreatitis based on dilated common bile duct and hyperechoic or mixed-echoic pancreas in abdominal ultrasonographic examination and serum biochemical abnormalities, such as high serum bilirubin, cholesterol, and increased cholestatic enzyme activity. Percutaneous ultrasound-guided cholecytocentesis(PUCC) was performed to examine bile and decompress the gall bladder. After PUCC with medical therapy, both dogs were steadily improved clinical signs of jaundice and anorexia. Also, cholestatic enzyme activity and serum bilirubin concentration decreased. Any complications that have been described in previous studies, such as peritonitis resulting from bile leakage and hemorrhage, were not identified. It is assumed that percutaneous ultrasound guided cholecystocentesis may be an useful diagnostic and therapeutic tool in canine gallbladder disease and can be used easily and safely to gain bile for diagnosis of bacterial cholecytitis.

  • Cholangiocarcinoma (CCA) is the most common cancer in northeastern Thailand. At present, effective diagnosis of CCA either in humans or animals is not available. Monitoring the development and progression of CCA in animal models is essential for research and development of new promising chemotherapeutics. Ultrasonography has been widely used for screening of bile duct obstruction in CCA patients. In this study, we preliminarily investigated the applicability of ultrasonography to monitor the development and progression of CCA in Syrian golden hamsters (n=8) induced by Opisthorchis viverrini (OV)/dimethylnitrosamine (DMN) administration. Ultrasonography and histopathological examination of hamsters was performed at week 0, 20, 24 and 28 of OV infection or at the start of water/Tween-80 administration to controls. The ultrasonographic images of liver parenchyma and gallbladders of OV/DMN-induced CCA hamsters showed sediments in gallbladder, thickening of gallbladder wall, and hypoechogenicity of liver parenchyma cells. The ultrasonographic images of liver tissues were found to correlate well with histopathological examination. Although ultrasonography does not directly detect the occurrence of CCA, it reflects the thickening of bile ducts and abnormality of liver tissues. It may be applied as a reliable tool for monitoring the development and progression of CCA in animal models in research and development of new promising chemotherapeutics for CCA.
