Endoscopic treatment of biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants: Lessons learned from single-balloon enteroscopy-assisted ERCP

引用

Hepatobiliary & Pancreatic Diseases international 2024年第5期23卷 509-514页

作者： Rodrigo Garcés-Durán Laurent Monino Pierre H Deprez Hubert Piessevaux Tom G Moreels Department of Gastroenterology and Hepatology Universitécatholique de LouvainCliniques Universitaires Saint-LucAvenue Hippocrates 101200 BrusselsBelgium

Background: Endoscopic treatment of biliopancreatic pathology is challenging due to surgically altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to evaluate the feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography(sBE-ERCP) to treat biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants. Methods: We retrospectively analyzed 106 sBE-ERCP procedures in 46 patients with Whipple's variants. Technical and clinical success rates and adverse events were evaluated. Results: Biliary sBE-ERCP was performed in 34 patients and pancreatic sBE-ERCP in 17, including 5 with both indications. From a total of 106 sBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adverse event rate was 8/76(11%), without serious adverse events. From a total of 106 sBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30(80%) procedures( P = 0.194 vs. biliary sBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 vs. biliary sBE-ERCP). Mild adverse event rate was 6/30(20%)( P = 0.194 vs. biliary sBE-ERCP), without serious adverse events. After sBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternative therapeutic options. Conclusions: Biliopancreatic pathology after Whipple's pancreaticoduodenectomy variants can be treated using sBE-ERCP without serious adverse events. Technical and clinical success rates are high for biliary indications, whereas clinical success rate of pancreatic indications is significantly lower. sBE-ERCP can be considered as first-line treatment option in this patient group with surgically altered anatomy.

A hydrodynamic modelling of wave-activated bodies for wavelet marine regions

引用

CLEAn EnERGY 2024年第2期8卷 35-47页

作者： Peh, J. s. Muhieldeen, Mohammed W. shuaib, n. H. UCsi Univ Fac Engn Technol & Built Environm Mech Engn Dept Kuala Lumpur 56000 Malaysia MTC Engineer sdn Bhd Shah Alam Selangor Malaysia

Recently, most wave energy research has targeted sea areas with high power density under extreme wave conditions for deployment. This trend often leads to higher energy costs for wave power plants. However, many marine areas with low power density, characterized by wavelet conditions and less destructive forces than extreme wave conditions, remain underexplored. Therefore, this study aimed to propose a wave-activated body model for sea regions with wavelet conditions. The wave-activated body design process encompassed site selection, parameter determination, geometry design, comparison and performance evaluation using the AnsYs (R) AQWA model. The results indicated that the proposed device achieved the desired heave motion, with an amplitude range of 1.2 to -2.5 m, validating its potential for deployment in marine regions with wavelet conditions. notably, while the proposed design is optimized for wavelet conditions, it was found to have potential limitations in extreme wave environments. This observation emphasizes the challenge of formulating a generalized design suitable for both conditions. Consequently, it is pivotal for wave-activated body designs to be customized based on the specific ocean conditions they target, underscoring the need for specialized designs of wave energy converters that consider the unique wave characteristics of their deployment sites. A wave-activated body is designed for energy generation in ocean regions with wavelet conditions. Hydrodynamic modelling is carried out for two locations with different wave characteristics to determine the optimum conditions for deployment. Graphical Abstract

Advanced oxidation via the synergy of C-defective/C-O band modified ultrathin porous g-C3n4 and PMs for efficient photothermal degradation of bisphenol pollutants and lignin derivatives

引用

Green Energy & Environment 2024年第7期9卷 1159-1170页

作者： Liquan Jing Meng Xie Yuanguo Xu Chun Tong Xia Du Heng Zhao na Zhong Huaming Li Jinguang Hu school of Chemistry and Chemical Engineering Jiangsu University Department of Chemical and Petroleum Engineering University of Calgary school of Pharmacy Jiangsu University school of Material science & Chemical Engineering Harbin University of Science and Technology institute for Energy Research Jiangsu University

This work uses thermal polymerization of urea nitrate, oxyacetic acid and urea as the raw material to prepare ultra-thin porous carbon nitride with carbon defects and C-O band（OA-Un-Cn）. Density functional theory（DFT） calculations showed OA-Un-Cn had narrower band gap,faster electron transport and a new internal construction electric field. Additionally, the prepared OA-Un-Cn significantly enhanced photocatalytic activation of peroxymonosulfate（PMs） due to enhanced light absorption performance and faster electron overflow. As the result, the OA-Un-Cn/PMs could entirely degrade bisphenol A（BPA） within 30 min, where the photodegradation rate was 81.8 and 7.9 times higher than that of g-C3n4and OA-Un-Cn, respectively. Beyond, the OA-Un-Cn/PMs could likewise degrade other bisphenol pollutants and sodium lignosulfonate efficiently. We suggested possible photocatalytic degradation pathways accordingly and explored the toxicity of its degradation products. This work provides a new idea on the development of advanced photocatalytic oxidation processes for the treatment of bisphenol pollutants and lignin derivatives, via a metal-free photothermal-catalyst.
