We report a new small molecular acceptor, ITIC-OEG, which is based on indacenodithieno[3,2-b]thiophene and 1,1-（dicyanomethylene）-3- indanone including oligoethyleneglycol （OEG） side-chains. ITIC-OEG was found to have higher dielectric constant （ε1=5.6} than that of a reference molecule of ITIC with normal alkyl substituents （ε1=3.9）. The dielectric constant of medium influences significantly the exciton binding energy and the resulting charge separation and recombination. The optical, electrochemical and morphological properties of ITIC-OEG and its photovoltaic characteristics were investigated by blending with a semi-crystalline donor polymer, PPDT2FBT, with comparison to those of ITIC. ITIC-OEG shows more red-shifted absorption and stronger crystalline packing than ITIC. However, the lower photovoltaic performance （with 1.58% power conversion efficiency, PCE） was measured for PPDT2FBT-ITIC-OEG, compared to PPDT2FBT：ITIC （5..52% PCE）. The incompatibility between PPDT2FBT and ITIC-OEG （due to high hydrophilic nature of OEG chains） resulted in poor intermixing with large domain separation over 300 nm, showing inefficient charge separation and significant charge recombination. Therefore, to investigate the effect of dielectric constant of the materials on the charge separation and recombination, the blend morphology of the PPDT2FBT：ITIC-OEG should be optimized first by improving their miscibility and phase separation.

Transgastric endoscopic necrosectomy has been recently introduced as the effective and alternative management of infected pancreatic necrosis and pancreatic abscess. However,up to 40% of patients who undergo endoscopic necrosectomy may need an additional percutaneous approach for subsequent peripancreatic fluid collection or non-resolution of pancreatic necrosis. This percutaneous approach may lead to persistent pancreatocutaneous fistula,which remains a serious problem and usually requires prolonged hospitalization,or even open-abdominal surgery. We describe the first case of pancreatocutaneous fistula and concomitant abdominal wall defect following transgastric endoscopic necrosectomy and percutaneous drainage,which were endoscopically closed with fibrin glue injection via the necrotic cavity.
