RESUMO
BACKGROUND: No consensus exists regarding the best reconstruction style after total gastrectomy (TG). Roux-en-Y oesophagojejunostomy is a simple option for gastrointestinal tract reconstruction. Recently, jejunal pouch reconstruction has been suggested as an appropriate approach. We compared the postoperative outcomes of the two surgical approaches using a well-characterized cohort of gastric carcinoma patients. METHODS: A total of 60 patients who underwent TG were divided into two groups according to the reconstruction style. Both groups were compared regarding patient characteristics, perioperative data and quality of life (QoL), which was assessed using the Spitzer QoL index (QLI) and Visick grade. The incidence of long-term surgery-related complications, including reflux oesophagitis, dumping syndrome, and retention syndrome, was also compared to evaluate postoperative restoration. RESULTS: Both study groups were comparable with respect to general patient characteristics. No mortality or no significant differences in surgery-related data were found except in the operation time. Compared to Orr Roux-en-Y reconstruction, pouch reconstruction was associated with a longer procedure time, a lower incidence of dumping/retention syndrome and better QoL parameters (p < 0.05). CONCLUSION: In this study, jejunal pouch reconstruction after TG was superior to the traditional Roux-n-Y oesophagojejunostomy with respect to improved dietary intake and QoL.

RESUMO
The present study investigated the effects of Colchicine on gastric carcinoma (GC) cells and explored its possible mechanisms underlying such effects. The results of MTT and colony formation assays showed that Colchicine (2, 5, and 10 ng/ml) markedly inhibited the proliferation of AGS and NCI-N87 cells in a dose-dependent manner. It also led to a reduction in cell migration in both GC cells as determined by Transwell migration assay. Mover, data form Hoechst 33342 staining and flow cytometry assay indicated that Colchicine (2, 5, and 10 ng/ml) promoted the apoptosis of NCI-N87 cells. In addition, the release of cytochrome c, the activation of bax, and the inhibition of bcl-2 were observed in NCI-N87 cells treated with Colchicine. Furthermore, the in vivo experiment further confirmed that Colchicine administration remarkably suppressed the tumor growth in nude mice via induction of apoptosis at 0.05 and 0.1 mg/kg. In addition, no visible toxicity was observed in liver and renal tissue of mice. This finding suggests that Colchicine-induced apoptosis is associated with caspase-3-mediated mitochondrial apoptotic pathways.
