Comparison of long-term oncologic outcomes laparoscopy-assisted gastrectomy and open gastrectomy for gastric cancer.

Purpose: Laparoscopy-assisted gastrectomy (LAG) is proven by considerable studies as a safe procedure for early gastric cancer (EGC), but its long-term oncologic outcomes in advanced gastric cancer (AGC) have not been well-described. This study aimed at verifying the non-inferiority of LAG in the treatment of EGC and comparing the oncological feasibility of LAG and open gastrectomy (OG) for AGC.

Methods: A total of 209 consecutive patients who underwent LAG or OG with D2 lymph node dissection between December 2008 and November 2012 were included.

[Occurrence and Ecological Risk of Eight Typical PhACs in Surface Water and Its Impact on ].

The occurrence and risk assessment of eight typical pharmaceutical active compounds (PhACs) in a receiving water body of wastewater treatment plant effluent were investigated. The results showed that the total concentrations of eight PhACs in summer and winter ranged from 27.6 to 226.
