The SIMENDO is an affordable virtual reality simulator designed to train basic psychomotor skills for endoscopic surgery. This study aimed first to establish construct validity by determining which parameters can discriminate groups with different experience levels, and second to establish the extent to which training is useful by determining when inexperienced groups reach expert level. ⋯ The study was able to establish construct validity for the training program with the simulator under study. The learning curve showed that training with this simulator is useful for subjects with or without limited endoscopic experience. Furthermore, previous endoscopic camera navigation already improves motor skills to more than the basic level.

Continuous insulin infusion (CII) is proven to decrease morbidity and mortality in surgical critical care patients. This study compared standard insulin therapy with CII in type 2 diabetes patients undergoing elective bariatric surgical procedures in a community hospital. ⋯ Perioperative CII can be administered safely to diabetic patients undergoing bariatric surgery. The insulin requirements in this population are higher than expected. Our study showed a decrease in the number of postoperative cholecystectomies in the CII group, but no effect on the stricture rate and an increase in the number of patients with postoperative port-site infections.

Commonly used perioperative measurements of hemodynamics, such as Swan-Ganz catheter assessment, are invasive and may not be reliable under pneumoperitoneum. The purpose of this study was to validate the use of esophageal Doppler for noninvasive hemodynamic monitoring under pneumoperitoneum in an experimental pig model. ⋯ Esophageal Doppler monitoring is a valid noninvasive method of estimating cardiac output at baseline and during pneumoperitoneum in a porcine model. Corrected flow time did not correlate with other estimates of preload at baseline or during pneumoperitoneum.

Many patients still suffer severe acute pain in the postoperative period. Although guidelines for treating acute pain are widely published and promoted, most do not consider procedure-specific differences in pain experienced or in techniques that may be most effective and appropriate for different surgical settings. The procedure-specific postoperative pain management (PROSPECT) Working Group provides procedure-specific recommendations for postoperative pain management together with supporting evidence from systematic literature reviews and related procedures at http://www.postoppain.org ⋯ Transparency in PROSPECT processes allows the users to be fully aware of any limitations of the evidence and recommendations, thereby allowing for appropriate decisions in their own practice setting.

Randomized Controlled Trial
Prospective randomized study on perioperative enteral immunonutrition in laparoscopic colorectal surgery.
Perioperative nutrition for patients undergoing colon surgery seems to be effective in reducing catabolism and improving immunologic parameters. A relatively low-fiber and highly absorbable diet may facilitate the intestinal cleansing and loop relaxation fundamental for laparoscopic surgery with a lower dose of iso-osmotic laxative. ⋯ Perioperative immunonutrition proved to be safe and useful in increasing the perioperative immunologic cell response. It may contribute toward improving the preparation and relaxation of the intestinal loops despite the shorter intestinal preparation.
