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.

Randomized Controlled Trial Clinical Trial
Laparoscopic versus open subtotal gastrectomy for distal gastric cancer: five-year results of a randomized prospective trial.
The aim of this study was to compare technical feasibility and both early and 5-year clinical outcomes of laparoscopic-assisted and open radical subtotal gastrectomy for distal gastric cancer. ⋯ Laparoscopic radical subtotal gastrectomy for distal gastric cancer is a feasible and safe oncologic procedure with short- and long-term results similar to those obtained with an open approach. Additional benefits for the LG were reduced blood loss, shorter time to resumption of oral intake, and earlier discharge from hospital.

To review the physiologic effects of carbon dioxide (CO2) pneumoperitoneum in the morbidly obese. ⋯ Morbidly obese patients undergoing laparoscopic bariatric surgery are at risk for intraoperative complications relating to the use of CO2 pneumoperitoneum. Surgeons performing laparoscopic bariatric surgery should understand the physiologic effects of CO2 pneumoperitoneum in the morbidly obese and make appropriate intraoperative adjustments to minimize the adverse changes.

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.

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.
