Human alveolar echinococcosis (AE) is a potentially deadly disease; recent studies have shown that the endemic area of Echinococcus multilocularis , its causative agent, is larger than previously known. This disease has low prevalence and remains underreported in Europe. Emerging clinical data show that diagnostic difficulties are still common. We report on a 76-year old patient suffering from AE lesions restricted to the left lobe of the liver who underwent a curative extended left hemihepatectomy. Prior to the resection a liver biopsy under the suspicion of an atypical malignancy was performed. After the intervention he developed a pseudoaneurysm of the hepatic artery that was successfully coiled. Surprisingly, during surgery, the macroscopic appearance of the tumour revealed a growth pattern that was rather typical for cystic echinococcosis (CE), i.e. , a gross tumour composed of multiple large vesicles with several centimeters in diameter. In addition, there were neither extensive adhesions nor infiltrations of the neighboring pancreas and diaphragm as was expected from previous imaging results. The unexpected diagnosis of AE was confirmed by definite histopathology, specific polymerase chain reaction and serology results. This is a rare case of unusual macroscopic presentation of AE that posed immense diagnostic challenges and had an eventful course. To our knowledge this is the first case of an autochthonous infection in this particular geographic area of Germany, the federal state of Saxony. This report may provide new hints for an expanding area of risk for AE and emphasizes the risk of complications in the scope of diagnostic procedures and the limitations of modern radiological imaging. 展开更多

AIM: To evaluate the efficacy of endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA) for grading pancreatic neuroendocrine tumors(PNETs).METHODS: A total of 22 patients were diagnosed with PNET by EUS-FNA between October 2001 and December 2013 at Fukushima Medical University Hospital.Among these cases,we targeted 10 PNET patients who were evaluated according to the World Health Organization(WHO) 2010 classification.Surgery was performed in eight patients,and chemotherapy was performed in two patients due to multiple liver metastases.Specimens obtained by EUS-FNA were first stained with hematoxylin and eosin and then stained with chromogranin,synaptophysin,CD56,and Ki-67.The specimens were graded by the Ki-67 index according to the WHO 2010 classification.Specimens obtained by surgery were graded by the Ki-67 indexand mitotic count(WHO 2010 classification).For the eight specimens obtained by EUS-FNA,the Ki-67 index results were compared with those obtained by surgery.In the two cases treated with chemotherapy,the effects and prognoses were evaluated.RESULTS: The sampling rate for histological diagnosis by EUS-FNA was 100%.No adverse effects were observed.The concordance rate between specimens obtained by EUS-FNA and surgery was 87.5%(7/8).Fo r t h e t w o c a s e s t re a t e d w i t h c h e m o t h e ra p y,case 1 received somatostatin analog therapy and transcatheter arterial infusion(TAI) targeting multiple liver metastases.Subsequent treatment consisted of everolimus.During chemotherapy,the primary tumor remained unconfirmed,although the multiple liver metastases diminished dramatically.Case 2 was classified as neuroendocrine carcinoma(NEC) according to the Ki-67 index of a specimen obtained by EUS-FNA; therefore,cisplatin and irinotecan therapy was started.However,severe adverse effects,including renal failure and diarrhea,were observed,and the therapy regimen was changed to cisplatin and etoposide.TAI targeting multiple liver metastases was performed.Although the liver metastases diminished,the primary tumor remained unconfirmed.These chemotherapy regimens had immediate effects for both unresectable neuroendocrine tumor(NET) and NEC cases.These two subjects are still alive.CONCLUSION: EUS-FNA was effective for PNET diagnosis and Ki-67 index grading for WHO 2010 classification,enabling informed decisions on unresectable PNET treatment by identifying NET or NEC. 展开更多

Abnormal innate immune responses toward luminal bacteria play an important role in the pathogenesis of inflammatory bowel disease.It has been demonstrated that bacteria having CpG DNA ameliorate experimental colitis in mice,and Toll-like receptor 9 (TLR9) signaling mediates the anti-inflammatory effects in mouse colonic inflammation.A gene variation in NOD2/CARD15 has been reported in Crohn's disease (CD) patients in Western countries,but this variation has not been identified in Japanese CD patients.Therefore,we hypothesized that TLR9 is a key factor in the development of ulcerative colitis (UC),and we investigated gene mutations and polymorphisms of TLR9 in Japanese UC patients.Three single nucleotide polymorphisms (SNPs) in TLR9 were identified in healthy controls,and were assessed in 48 UC patients and 47 healthy controls.Control subjects were matched for age,sex and date of blood sampling from among a subgroup of participants.We found that TLR9-1486CC,1174GG and 2848AA increase the risk of UC [odds ratio (OR) 2.64,95% confidence interval (95% CI):1.73-6.53,P=0.042],and TLR9-1486TT,1174AA and 2848GG decrease the risk of UC (OR 0.30,95% CI:0.10-0.94,P=0.039),although there were no correlations between SNPs and disease phenotype or TLR9 mRNA expression.These findings suggest that TLR9 polymorphisms are associated with increased susceptibility to UC. 展开更多

AIM: To compare clinicopathological features of acute presentation of type 1 autoimmune hepatitis (AIH) with or without centrilobular necrosis (CN). METHODS: Our study comprised 41 patients with biopsy-proven acute presentation (acute exacerbation phase 36, acute hepatitis phase 5) of type 1 AIH at our hospital from 1975 to 2009. Elevated serum alanine aminotransferase (ALT) (> 5x upper limit of normal) identified acute presentation of the disease. We compared clinicopathological features of these AIH patients with or without CN. The data used for analysis included patient background (age, sex, type of disease, presence of complications with other autoimmune diseases, human leukocyte antigen, and International Autoimmune Hepatitis Group score), clinical parameters at presentation (ALT, alkaline phosphatase, IgG, anti-nuclear antibodies, and anti-smooth muscle antibodies), histology and therapy. RESULTS: CN was found in 13 (31.7%) patients with acute presentation (acute exacerbation phase 10, acute hepatitis phase 3) of AIH. Serum IgG levels of patients with CN were significantly lower than those of patients without CN (mean: 2307 mg/dL vs 3126 mg/dL, P < 0.05), while antinuclear antibody-negative rates were significantly higher (30.7% vs 3.5%, P < 0.05). However, other clinical features were similar between the two groups. The frequency of advanced fibrosis in patients with CN was significantly lower than in patients without CN (F0-2: 84.6% vs 35.7%, F3-4: 15.4% vs 64.3%, P < 0.05). Other histological features were similar between the two groups. Although there was no significant difference between groups when evaluated using the revised original score (12 vs 14), the simplified AIH score of patients with CN was significantly lower (6 vs 7, P < 0.05). Frequency of DR4 was similar between patients with and without CN. CONCLUSION: CN is observed in both Japanese patients with acute hepatitis phase and acute exacerbation phase of type 1 AIH, although AIH with CN often shows clinical features of the genuine acute form. 展开更多

Prognosis is generally poor and survival is limited to a few months. Here we present a case of advanced ICC successfully treated by chemosensitivity test-guided systemic chemotherapy combining S-1 and cisplatin (CDDP). A 65-year-old woman with a liver tumor was referred to our hospital on November 21, 2007. Abdominal ultrasonography and computed tomography (CT) showed low-density masses of 50 and 15 mm in diameter, respectively in segment w of the liver and in the enlarged lymph node in the para-aorta. Ultrasonography-guided fine needle biopsy diagnosed the tumors as ICC. Since the patient was inoperable for lymph node metastasis, she underwent systemic chemotherapy with gemcitabine. Six months afcer initiation of chemotherapy, CT revealed ICC progression in the liver and pleural dissemination with pleural effusion. The patient was admitted to our hospital for anticancer drug sensitivity testing on June 9, 2008. Based on the sensitivity test results, we elected to administer systemic chemotherapy combining S-1 and CDDP. Two months into the second chemotherapy treatment, CT revealed a reduction of the tumors in the liver and lymph node and a decrease in pleural effusion.After eight cycles of the second chemotherapy, 17 mo after ICC diagnosis, she is alive and well with no sign of recurrence. We conclude that chemosensitivity testing may effectively determine the appropriate chemotherapy regimen for advanced ICC. 展开更多

AIM To examine the influence of night duty(ND) on endoscopic therapy for biliary duct stones.METHODS The subjects consisted of 133 patients who received initial endoscopic therapy for biliary duct stones performed by eight endoscopists after they had been on(ND group, n = 34 patients) or not [day duty(DD) group, n = 99 patients]. Patient characteristics(age, gender, history of abdominal surgery, transverse diameter of the largest stone, number of stones), years of experience of the endoscopists, endoscopic procedures [sphincterotomy, papillary balloon dilation(EPBD), papillary large balloon dilation(EPLBD)], and outcomes of initial endoscopy(procedure time; rate of stone removal by the first endoscopist; proceduresuccess rate by the first endoscopist: removal of stones or endoscopic retrograde biliary drainage; rate of final stone removal; final procedure success rate; complications; hospitalization after the procedure) were compared retrospectively between the two groups. History of abdominal surgery and treatment outcomes were also compared between the groups for each of the four endoscopists who performed most of the procedures in the ND group.RESULTS There were no significant differences regarding the number of treatments performed by each endoscopist or the years of experience between the ND and DD groups. The frequency of endoscopic retrograde cholangiopancreatography procedures did not differ significantly between the groups. There were also no significant differences regarding patient characteristics: age, gender, history of abdominal surgery(ND 7: Billroth II 4, R-Y 3; DD 18: double tract reconstruction 1, Billroth I 3, Billroth II 6, R-Y 7, duodenoduodenostomy for annular pancreas 1), transverse diameter of largest stone, and number of stones between the two groups. Among the treatment procedures, the endoscopic s p h i n c t e r o t o m y a n d E P B D r a t e s d i d n o t d i f f e r significantly between the groups. However, EPLBD was performed more frequently in the ND group [47.1%(16/34) v s 19.2%(19/99)]. Regarding outcomes, there were no significant differences in the rate of stone removal, procedure success rate, complications(ND: pancreatitis 1; DD: pancreatitis 6, duodenal bleeding 1, decreased blood pressure 1, hypoxia 2), or hospitalization after the procedure. However, the procedure time was significantly longer in the ND group(71.5 ± 44.7 vs 54.2 ± 28.8). Among the four endoscopists, there were no significant differences in patient history of abdominal surgery, removal of stones, or procedure success rate. However, the procedure time for one endoscopist was significantly longer in the ND group.CONCLUSION The time required for endoscopic therapy for bile duct stones might be influenced by ND. 展开更多

AIM: To evaluate the feasibility of using an automatedspring-loaded needle device for endoscopic ultrasound(EUS)-guided abdominal paracentesis(EUS-P) to see if this would make it easier to puncture the mobile and lax gastric wall for EUS-P.METHODS: The EUS database and electronic medical records at Fukushima Medical University Hospital were searched from January 2001 to April 2011. Patients with a history of cancer and who underwent EUS-P using an automated spring-loaded needle device with a 22-gauge puncture needle were included. The needle was passed through the instrument channel and advanced through the gastrointestinal wall under EUS guidance into the echo-free space in the abdominal cavity and ascitic fluid was collected. The confirmed diagnosis of malignant ascites included positive cytology and results from careful clinical observation for at least 6 mo in patients with negative cytology. The technical success rate, cytology results and complications were evaluated.RESULTS: We found 11 patients who underwent EUS-P with an automated spring-loaded needle device. In 4 cases, ascites was revealed only with EUS but not in other imaging modalities. EUS-P was done in 7 other cases because there was minimal ascitic fluid and no safe window for percutaneous abdominal aspiration. Ascitic fluid was obtained in all cases by EUS-P. The average amount aspirated was 14.1 mL(range 0.5-38 mL) and that was sent for cytological exam. The etiology of ascitic fluid was benign in 5 patients and malignant in 6. In all cases, ascitic fluid was obtained with the first needle pass. No procedure-related adverse effects occurred.CONCLUSION: EUS-P with an automated springloaded needle device is a feasible and safe method for ascites evaluation. 展开更多

A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC. 展开更多

We describe a case of gastric aberrant pancreas with acute pancreatitis followed up with subsequent endoscopic ultrasound. A 20-year-old woman known to have aberrant pancreas in the stomach was admitted to our hospital because of severe epigastralgia. Laboratory tests showed slight C reactive protein elevation without hyperamylasemia. Esophagogastroduodenoscopy revealed a swollen submucosal lesion (SML) to a greater degree compared with the previous findings. Subsequent endoscopic ultrasonography (EUS) revealed a swollen lesion of 35 mm in diameter. The internal echo-pattern was more hypoechoic than in the previous EUS. The border between the fourth layer (muscularis propria) and the SML was unclear. The anechoic lumen in the mass, considered as the ductal lumen, was dilated. Based on these results, we diagnosed the patient as having acute inflammation, resembling pancreatitis, in the aberrant pancreas. 展开更多
