Invasion of Artificial Vascular Graft into Duodenal Bulb after Living Donor Liver Transplantation

Surgical Science 2015年第2期6卷 71-74页

作者： Yu-Ju Hung Kuo-Hua Lin chen-te chou Chih-Jan Ko Ping-Yi Lin Chia-En Hsieh Hsu-Heng Yen Yao-Li chen Department of Surgery Changhua Christian Hospital Changhua Chinese Taipei Department of Medical Imaging Changhua Christian Hospital Changhua Chinese Taipei Transplant Medicine & Surgery Research Centre Changhua Christian Hospital Changhua Chinese Taipei Department of Gastroenterology Changhua Christian Hospital Changhua Chinese Taipei

Artificial vessel grafts are used for outflow reconstruction in living donor liver transplantation (LDLT). We report a very rare case of invasion of an artificial vascular graft into the duodenal bulb after LDLT. A 54-year-old man underwent LDLT in August 2012. A right hemiliver without a middle hepatic vein was used as a graft. The outflow of segment V was created by anatomizing an artificial graft to the inferior vena cava. During outpatient follow-up, the patient complained of acid regurgitation but did not experience abdominal pain. Panendoscopy was arranged and it revealed that the artificial graft had invaded the duodenal bulb. Operation was performed to remove the graft and the patient discharged after fourteen days of hospital stay. Invasion of artificial vascular grafts to adjacent organs is rare, but happens in living donor liver transplantation. It may be caused by inappropriate vessel graft length and adhesion between the graft and adjacent organs.

Photoassisted Fenton degradation of phthalocyanine dyes from wastewater of printing industry using Fe(Ⅱ)/γ-Al_2O_3 catalyst in up-flow fluidized-bed

Journal of Environmental Sciences 2014年第6期26卷 1307-1312页

作者： Hsuhui cheng Shihjie chou Shiaoshing chen Chiajen Yu Department of Design for Sustainable Environment Mingdao University Institute of Environment Engineering and Management National Taipei University of Technology

Fe（II）/γ-Al2O3 powders synthesized using the dipping method were produced from a mixed aqueous solution containing aluminium oxide （γ-Al2O3） and iron（II）-precursor （FeSO4）, and used for photoFenton degradation of phthalocyanine dyes （PCs） under ultraviolet （UV） irradiation in an up-flow fluidized bed. The catalysts were characterized by XRD, ESCA, BET, EDS and SEM. The results showed that Fe2＋ ion was compounded on the γ-Al2O3 carder. The effects of different reaction parameters such as catalyst activity, dosage and solution pH on the decolorization of PCs were assessed. Results indicated that maximum decolorization （more than 95%） of PCs occurred with 20 wt% Fe（II）/γ-Al2O3 catalyst （dosage of 60 g/L） using a combination of UV irradiation and heterogeneous Fenton system. The degradation efficiency of PCs increases as pH decreases, exhibiting a maximum efficiency at pH 3.5. The recycled catalyst was capable of repeating three runs without a significant decrease in treatment efficiency, and this demonstrated the stability and reusability of catalyst.
