“The modern-day surgeon is frequently exposed to new technologies and instrumentation. Robotic surgery (RS) has evolved as a minimally invasive technique aimed to improve clinical outcomes. RS has the potential to alleviate the inherent limitations of laparoscopic surgery such as two dimensional imaging, limited

Vorasidenib ic50 instrument movement and intrinsic human tremor. Since the first reported robot-assisted surgical procedure performed in 1985, the technology has dramatically evolved and currently multiple surgical specialties have incorporated RS into their daily clinical armamentarium. With this exponential growth, it should not come as a surprise the ever growing requirement for surgeons trained in RS as well as the interest from residents to receive robotic exposure during their training. For this reason, the establishment of set criteria for adequate and standardized training and credentialing of surgical residents, fellows and those trained surgeons wishing to perform RS has become a priority. In this rapidly evolving field, we herein review the past, present and future of robotic technologies selleck products and its penetration into different surgical specialties. (C) 2010 Elsevier Ltd.

“A detailed analysis of the use of an optical cavity

to enhance picosecond ultrasonic signals is presented. The optical cavity is formed between a distributed Bragg reflector and the metal thin film samples to be studied. Experimental results for Al and Cu films show enhancement of acoustic signals by up to two orders of magnitude and are in good agreement with calculated results based on a previously established model. This technique

provides an efficient method for detecting sound in materials with small piezo-optic coefficients and makes it possible to determine the actual pulse shape of the returning acoustic echoes.”
“Natural orifice transluminal this website endoscopic surgery (NOTES) is a new concept that attempts to reduce the impact of surgery on the patient. In surgical oncology several studies have already revealed that a minimally invasive approach provides at least the same, if not a better, long-term outcome. One could hypothesize that a less invasive approach such as NOTES could further enhance such advantages. Since its initial description, NOTES has become clinical reality and today nearly every organ is accessible by a transluminal approach, in at least the experimental setting. Subsequent to published research, first clinical studies on NOTES in oncology were reported and the accuracy of transgastric peritoneoscopy for staging of pancreas cancer was shown to be similar to laparoscopy in humans. A NOTES gastro-jejunostomy via transgastric access has also been proposed to decrease invasiveness of palliative treatment of duodenal, biliary and pancreatic cancers.
