| 1 | H pylori and gastric cancer: Shifting the global burden显示文摘Infection with H pylori leads to a persistent chronic in?ammation of the gastric mucosa, thereby increasing the risk of distal gastric adenocarcinoma. Numerous studies have determined a clear correlation between H pylori infection and the risk of gastric cancer; however, general eradication is not recommended as cancer prophylaxis and time points for treatment remain controversial in different areas of the world. Prevalence rates in Western countries are decreasing, especially in younger people (< 10%); and a decline in distal gastric adenocarcinoma has been observed. Risk groups in Western countries still show considerably higher risk of developing cancer, especially in patients infected with cagA + strains and in persons harboring genetic polymorphism of the IL-1B promoter (-511T/T) and the corresponding IL-1 receptor antagonist (IL-1RN*2). Thus, general eradication of all infected persons in Western countries not recommended and is limited to risk groups in order to achieve a risk reduction. In contrast, infection rates and cancer prevalence are still high in East Asian countries. A prevention strategy to treat infected persons may avoid the development of gastric cancer to a large extent and with enormous clinical importance. However, studies in China and Japan indicate that prevention of gastric cancer is effective only in those patients that do not display severe histological changes such as atrophy and intestinal metaplasia. Thus, prophylactic strategies to prevent gastric cancer in high risk populations such as China should therefore especially aim at individuals now at younger age when the histological alterations caused by the bacterial infection was still reversible. In countries with a low prevalence of gastric cancer, risk groups carrying cagA+ strains and IL-1 genetic polymorphisms should be identi?ed and treated. | Christian Prinz Susanne Schwendy Petra Voland | 2006 | World Journal of Gastroenterology2006，12，34： | 33 |
| 2 | Long-term outcome and prognostic factors of patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the long-term outcome and prognostic factors of patients with hilar cholangiocarinoma. METHODS: Ninety-six consecutive patients underwent treatment for malignant hilar bile duct tumors during 1995–2005. Of the 96 patients, 20 were initially treated with surgery (n = 2 R0 / n = 18 R1). In non-operated patients, data analysis was performed retrospectively. RESULTS: Among the 96 patients, 76 were treated with endoscopic transpapillary (ERC, n = 45) and/or percutaneous transhepatic biliary drainage (PTBD, n = 31). The mean survival time of these 76 patients undergoing palliative endoscopic and/or percutaneous drainage was 359 ± 296 d. The mean survival time of patients with initial bilirubin levels > 10 mg/dL was significantly lower (P < 0.001) than patients with bilirubin levels < 10 mg/dL. The mean survival time of patients with Bismuth stage Ⅱ (n = 8), Ⅲ (n = 28) and Ⅳ (n = 40) was 496 ± 300 d, 441 ± 385 d and 274 ± 218 d, respectively. Thus, patients with advanced Bismuth stage showed a reduced mean survival time, but the difference was not significant. The type of biliary drainage had no significant beneficial effect on the mean survival time (ERC vs PTBD, P = 0.806). CONCLUSION: Initial bilirubin level is a significant prognostic factor for survival of patients. In contrast, age, tumor stage according to the Bismuth-Corlette classification, and types of intervention are not significant prognostic parameters for survival. Palliative treatment with endoscopic or percutaneous biliary drainage is still suboptimal, new diagnostic and therapeutic tools need to be evaluated. | Andreas Weber Sonja Landrock Jochen Schneider Manfred Stangl Bruno Neu Peter Born Meinhard Classen Thomas Rsch Roland M Schmid Christian Prinz | 2007 | World Journal of Gastroenterology2007，13，9： | 23 |
| 3 | Diagnostic approaches for cholangiocarcinoma显示文摘Cholangiocarcinomas arise from the epithelial cells of the bile ducts and are associated with poor prognosis. Despite new diagnostic approaches, the definite diagnosis of this malignancy continues to be challenging. Cholangiocarcinomas often grow longitudinally along the bile duct rather than in a radial direction. Thus, large tumor masses are frequently absent and imaging techniques, including ultrasound, CT, and MRI have only limited sensitivity. Tissue collection during endoscopic (ERCP) and/or percutaneous transhepatic (PTC) procedures are usually used to confirm a definitive diagnosis of cholangiocarcinoma. However, forceps biopsy and brush cytology provide positive results for malignancy in about only 50% of patients. Percutaneous and peroral cholangioscopy using fiber-optic techniques were therefore developed for direct visualization of the biliary tree, yielding additional information about endoscopic appearance and tumor extension, as well as a guided biopsy acquistion. Finally, endoscopic ultrasonography (EUS) complements endoscopic and percutaneous approaches and may provide a tissue diagnosis of tumors in the biliary region through fine-needle aspiration. In the future, new techniques allowing for early detection, including molecular markers, should be developed to improve the diagnostic sensitivity in this increasing tumor entity. | Andreas Weber Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，26： | 21 |
| 4 | In vitro activity of moxifloxacin and piperacillin/sulbactam against pathogens of acute cholangitis显示文摘AIM: To analyze the in vitro activity of moxifloxacin and piperacillin/sulbactam against pathogens isolated from patients with acute cholangitis. METHODS: In this prospective study a total of 65 patients with acute cholangitis due to biliary stone obstruction (n = 7), benign biliary stricture (n = 16), and malignant biliary stricture (n = 42) were investigated with regard to spectrum of bacterial infection and antibiotic resistance. Pathogens were isolated from bile cultures in all study patients. In 22 febrile patients, blood cultures were also obtained. In vitro activity of moxifloxacin and piperacillin/ sulbactam was determined by agar diffusion. RESULTS: Thirty-one out of 65 patients had positive bile and/or blood cultures. In 31 patients, 63 isolates with 17 different species were identified. The predominant strains were Enterococcus species (26/63), E.coli (13/63) and Klebsiella species (8/63). A comparable in vitro activity of moxifloxacin and piperacillin/sulbactam was observed for E.coli and Klebsiella species. In contrast, Enterococcus species had higher resistances towards moxifloxacin. Overall bacteria showed antibiotic resistances in vitro of 34.9% for piperacillin/sulbactam and 36.5% for moxifloxacin.CONCLUSION: Enterococcus species , E.coli and Klebsiella species were the most common bacteria isolated from bile and/or blood from patients with acute cholangitis. Overall, a mixed infection with several species was observed, and bacteria showed a comparable in vitro activity for piperacillin/sulbactam and moxifloxacin. | Andreas Weber Wolfgang Huber Klaus Kamereck Philipp Winkle Petra Voland Hans Weidenbach Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，20： | 18 |
| 5 | Endoscopic transpapillary brush cytology and forceps biopsy in patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the sensitivity of brush cytology and forceps biopsy in a homogeneous patient group with hilar cholangiocarcinoma.METHODS: Brush cytology and forceps biopsy were routinely performed in patients with suspected malignant biliary strictures. Fifty-eight consecutive patients undergoing endoscopic retrograde cholangio-pancreatography (ERCP) including forceps biopsy and brush cytology in patients with hilar cholangiocarcinoma between 1995-2005.RESULTS: Positive results for malignancy were obtained in 24/58 patients (41.4%) by brush cytology and in 31/58 patients (53.4%) by forceps biopsy. The combination of both techniques brush cytology and forceps biopsy resulted only in a minor increase in diagnostic sensitivity to 60.3% (35/58 patients). In 20/58 patients (34.5%), diagnosis were obtained by both positive cytology and positive histology, in 11/58 (19%) by positive histology (negative cytology) and only 4/58 patients (6.9%) were confirmed by positive cytology (negative histology).CONCLUSION: Brush cytology and forceps biopsy have only limited sensitivity for the diagnosis of malignant hilar tumors. In our eyes, additional diagnostic techniques should be evaluated and should become routine in patients with negative cytological and histological findings. | Andreas Weber Claus von Weyhern Falko Fend Jochen Schneider Bruno Neu Alexander Meining Hans Weidenbach Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，7： | 17 |

| 16 | Endoscopic stent therapy in patients with chronic pancreatitis:A 5-year follow-up study显示文摘AIM:This study analyzed clinical long-term outcomes after endoscopic therapy,including the incidence and treatment of relapse. METHODS:This study included 19 consecutive patients(12 male,7 female,median age 54 years)with obstructive chronic pancreatitis who were admitted to the 2nd Medical Department of the Technical University of Munich.All patients presented severe chronic pancreatitis(stageⅢ°)according to the Cambridge classification.The majority of the patients suffered intermittent pain attacks.6 of 19 patients had strictures of the pancreatic duct;13 of 19 patients had strictures and stones.The first endoscopic retrograde pancreatography(ERP)included an endoscopic sphincterotomy, dilatation of the pancreatic duct,and stent placement.The first control ERP was performed 4 wk after the initial intervention,and the subsequent control ERP was performed after 3 mo to re-evaluate the clinical and morphological conditions.Clinical follow-up was performed annually to document the course of pain and the management of relapse.The course of pain was assessed by a pain scale from 0 to 10.The date and choice of the therapeutic procedure were documented in case of relapse. RESULTS:Initial endoscopic intervention was successfully completed in 17 of 19 patients.All 17 patients reported partial or complete pain relief after endoscopic intervention.Endoscopic therapy failed in 2 patients. Both patients were excluded from further analysis.One failed patient underwent surgery,and the other patient was treated conservatively with pain medication.Seventeen of 19 patients were followed after the successful completion of endoscopic stent therapy.Three of 17 patients were lost to follow-up.One patient was not avail-able for interviews after the 1st year of follow-up.Two patients died during the 3rd year of follow-up.In both patients chronic pancreatitis was excluded as the cause of death.One patient died of myocardial infarction, and one patient succumbed to pneumonia.All three patients were excluded from follow-up analysis.Followup was successfully completed in 14 of 17 patients.4 patients at time point 3,2 patients at time point 4,3 patients at time point 5 and 2 patients at time point 6 and time point 7 used continuous pain medication after endoscopic therapy.No relapse occurred in 57%(8/14) of patients.All 8 patients exhibited significantly reduced or no pain complaints during the 5-year follow-up.Seven of 8 patients were completely pain free 5 years after endoscopic therapy.Only 1 patient reported continuous moderate pain.In contrast,7 relapses occurred in 6 of the 14 patients.Two relapses were observed during the 1st year,2 relapses occurred during the 2nd year,one relapse was observed during the 3rd year,one relapse occurred during the 4th year,and one relapse occurred during the 5th follow-up year.Four of these six patients received conservative treatment with endoscopic therapy or analgesics.Relapse was conservatively treated using repeated stent therapy in 2 patients.Analgesic treatment was successful in the other 2 patients. CONCLUSION:57%of patients exhibited long-term benefits after endoscopic therapy.Therefore,endoscopic therapy should be the treatment of choice in patients being inoperable or refusing surgical treatment. | Andreas Weber Jochen Schneider Bruno Neu Alexander Meining Peter Born Stefan von Delius Monther Bajbouj Roland M Schmid Hana Algül Christian Prinz | 2013 | World Journal of Gastroenterology2013，19，5： | 1 |
