Multicenter Study
Prediction of recurrence after radical surgery for gastric cancer: a scoring system obtained from a prospective multicenter study.
The aim of this prospective multicenter study was to define a scoring system for the prediction of tumor recurrence after potentially curative surgery for gastric cancer. ⋯ The scoring system obtained with a regression model on the basis of our follow-up data is useful for defining subgroups of patients at a very low or very high risk of tumor recurrence after radical surgery for gastric cancer. Final results of the validation study are essential for a clinical application of the model.

To determine if increasing nitric oxide bioactivity by inclusion of ethyl nitrite (ENO) in the insufflation admixture would attenuate pneumoperitoneum-induced decreases in splanchnic perfusion. ⋯ The data indicate that ENO can effectively attenuate pneumoperitoneum-induced blood flow decreases within the peritoneal cavity. The result suggests a novel therapeutic method of regulating hemodynamic changes during laparoscopic procedures.

The objective of this study was to elucidate and define the pathophysiological mechanism(s) responsible for the clinically relevant phenomenon of posthepatic resection hypophosphatemia. ⋯ Hypophosphatemia after hepatic resection is a frequent occurrence. Transient isolated hyperphosphaturia and not increased phosphate utilization is the predominant cause of this phenomenon, although the identity of the agent involved remains to be identified.

To inform surgeons about the practical issues to be considered for successful integration of virtual reality simulation into a surgical training program. The learning and practice of minimally invasive surgery (MIS) makes unique demands on surgical training programs. A decade ago Satava proposed virtual reality (VR) surgical simulation as a solution for this problem. Only recently have robust scientific studies supported that vision ⋯ VR for improved performance of MIS is now a reality. However, VR is only a training tool that must be thoughtfully introduced into a surgical training curriculum for it to successfully improve surgical technical skills.
