| 1 | Double-balloon-enteroscopy-based endoscopic retrograde cholangiopancreatography in post-surgical patients显示文摘AIM: To evaluate double balloon enteroscopy (DBE) in post-surgical patients to perform endoscopic retrograde cholangiopancreatography (ERCP) and interventions. METHODS: In 37 post-surgical patients, a stepwise approach was performed to reach normal papilla or enteral anastomoses of the biliary tract/pancreas. When conventional endoscopy failed, DBE-based ERCP was performed and standard parameters for DBE, ERCP and interventions were recorded. RESULTS: Push-enteroscopy (overall, 16 procedures) reached enteral anastomoses only in six out of 37 post-surgical patients (16.2%). DBE achieved a high rate of luminal access to the biliary tract in 23 of the remaining 31 patients (74.1%) and to the pancreatic duct (three patients). Among all DBE-based ERCPs (86 procedures), 21/23 patients (91.3%) were successfully treated. Interventions included ostium incision or papillotomy in 6/23 (26%) and 7/23 patients (30.4%), respectively. Biliary endoprosthesis insertion and regular exchange was achieved in 17/23 (73.9%) and 7/23 patients (30.4%), respectively. Furthermore, bile duct stone extraction as well as ostium and papillary dilation were performed in 5/23 (21.7%) and 3/23 patients (13.0%), respectively. Complications during DBE-based procedures were bleeding (1.1%), perforation (2.3%) and pancreatitis (2.3%), and minor complications occurred in up to 19.1%. CONCLUSION: The appropriate use of DBE yields a high rate of luminal access to papilla or enteral anastomoses in more than two-thirds of post-surgical patients, allowing important successful endoscopic therapeutic interventions. | Martin Raithel Harald Dormann Andreas Naegel Frank Boxberger Eckhart G Hahn Markus F Neurath Juergen Maiss | 2011 | World Journal of Gastroenterology2011，17，18： | 9 |
| 2 | Effects of temperature,pH and O_(2) on the removal of hydrogen sulfide from biogas by external biological desulfurization in a full scale fixed-bed trickling bioreactor(FBTB)显示文摘Hydrogen sulfide(H_(2)S)is a critical component of biogas formed under anaerobic conditions by sulfur and sulfate reducing bacteria from animal manure and renewable energy crops.H_(2)S causes high corrosion in equipment,has a negative environmental impact,inhibits the biogas formation process and is furthermore odorous and toxic.Although several methods for internal and external desulfurization found their way into practice and had been explored at laboratory scale,no data were available on the performance of such methods in full scale practice,especially for an external fixed-bed trickling bioreactor(FBTB).The effects of temperature,pH and air ratio on H_(2)S removal efficiency(RE)were studied.The study was conducted at a research biogas plant with a given output of 96 m^(3) biogas per hour,and an H_(2)S concentration ranging between 500 ppm and 600 ppm(1 ppm=1 cm^(3)/m^(3))on average.The FBTB column has been designed to hold a packing volume of 2.21 m^(3) at a gas retention time of 84 seconds being loaded at an average of 32.88 g H_(2)S/(m^(3)·h).The highest H_(2)S RE of 98% was found at temperatures between 30℃ and 40℃.A major decline in RE to 21%-45%was observed at temperatures from 5℃ to 25℃.The results clearly showed a temperature optimum range for sulfate reducing bacteria.The results reveal that RE is little affected by different pH values and air ratios.During the experimental period,the practical suitability of the FBTB system could be proved while avoiding the disadvantages of internal biological desulfurization methods. | Hans-Joachim Naegele Jonas Lindner Wolfgang Merkle Andreas Lemmer Thomas Jungbluth Claus Bogenrieder | 2013 | International Journal of Agricultural and Biological Engineering2013，6，1： | 3 |
| 3 | Comparison of Hemospray~? and Endoclot? for the treatment of gastrointestinal bleeding显示文摘BACKGROUND Gastrointestinal(GI) bleeding is a common indication for endoscopy. For refractory cases, hemostatic powders(HP) represent 'touch-free' agents.AIM To analyze short term(ST-within 72 h-) and long-term(LT-within 30 d-) success for achieving hemostasis with HP and to directly compare the two agents Hemospray(HS) and Endoclot(EC).METHODS HP was applied in 154 consecutive patients(mean age 67 years) with GI bleeding.Patients were followed up for 1 mo(mean follow-up: 3.2 mo).RESULTS Majority of applications were in upper GI tract(89%) with following bleeding sources: peptic ulcer disease(35%), esophageal varices(7%), tumor bleeding(11.7%), reflux esophagitis(8.7%), diffuse bleeding and erosions(15.3%). Overall ST success was achieved in 125 patients(81%) and LT success in 81 patients(67%). Re-bleeding occurred in 27% of all patients. In 72 patients(47%), HP was applied as a salvage hemostatic therapy, here ST and LT success were 81% and64%, with re-bleeding in 32%. As a primary hemostatic therapy, ST and LT success were 82% and 69%, with re-bleeding occurring in 22%. HS was more frequently applied for upper GI bleeding(P = 0.04)CONCLUSION Both HP allow for effective hemostasis with no differences in ST, LT success and re-bleeding. | Francesco Vitali Andreas Naegel Raja Atreya Steffen Zopf Clemens Neufert Juergen Siebler Markus F Neurath Timo Rath | 2019 | World Journal of Gastroenterology2019，25，13： | 2 |
