Phenolphthalein-based cardo poly(ether ether ketone) (PEEKWC)/polyethyleneimine (PEI) crosslinkingmembranes were prepared by solution casting followed by solution reaction at room temperature. Theeffects of reaction time and PEI content on the membrane structure and gas separation performanceswere investigated. Light transmittance measure and AFM evidenced the relationship between themicrophase separation in PEEKWC-PEI membranes and reaction time. The CO2 permeability increasedwith the PEI content, while the N2 and CH4 permeability remained nearly constant. This result indicatedthat only CO2 was transported by the solution–diffusion mechanism and also that PEI exhibited a positivecontribution as afixed carrier for CO2 facilitated transport. Meanwhile the PEEKWC-PEI crosslinkingmembranes showed higher selectivities than the pure PEEKWC membrane. The highest CO2/N2 and CO2/CH4 selectivities were about 131 and 122 increasing from 33 and 30, respectively. The crosslinkingstructure of membranes improved the CO2 permeability stability.

Risk Factors for Duodenal Stump Leakage after Laparoscopic Gastrectomy for Gastric Cancer
Gu, Lihu,Zhang, Kang,Shen, Zefeng,Wang, Xianfa,Zhu, Hepan,Pan, Junhai,Zhong, Xin,Khadaroo, Parikshit Asutosh,Chen, Ping The Korean Gastric Cancer Association 2020 Journal of gastric cancer Vol. No.
Purpose: Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials and Methods: Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Rouxen-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2-12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment. Conclusions: The risk factors of DSL were BMI ≥24 kg/㎡, elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials: and Methods Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Roux-en-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun).

Nonsurgical treatments for DSL are preferred.
