Advances in Minimally Invasive Surgery

The minimally invasive approach in medicine is one of the most common areas of interest in surgery.Advances in Minimally Invasive Surgery describes the latest trends, indications, techniques, and approaches in minimally invasive surgery. It provides step-by-step instructions for both routine and diagnostic procedures via illustrations and video collection

Robot-assisted gastrectomy and oesophagectomy for cancer

Background: Robot-assisted surgery is a technically feasible alternative to open and laparoscopic surgery, which is being more frequently used in general surgery. We undertook this review to investigate whether robotic assistance provides a significant benefit for oesophagogastric cancer surgery. Methods: Electronic databases were searched for original English-language publications for robotic-assisted gastrectomy and oesophagectomy between January 1990 and October 2013. Results: Sixty-one publications were included. Thirty-five included gastrectomy, 31 included oesophagectomy and five included both operations. Several publications suggest that robot-assisted subtotal gastrectomy can be as safe and effective as an open or laparoscopic procedure, with equal outcomes with regard to the number of lymph nodes resected, overall morbidity and perioperative mortality, and length of hospital stay. Robotic assistance is associated with longer operation times but also with less blood loss in some reports. A significant benefit for robotic assistance has not been shown for the more extensive operations of oesophagectomy or total gastrectomy with D2-lymphadenectomy. There are very few oncologic data regarding local recurrence or long-term survival for any of the robotic operations. Conclusions: No significant differences in morbidity, mortality or number of lymph node harvested have been shown between robot-assisted and laparoscopic gastrectomy or oesophagectomy. Robotic surgery, with its relatively short learning curve, may facilitate reproducible minimally invasive surgery in this field but operation times are reportedly longer and cost differences remain unclear. Randomized trials with oncologic outcomes and cost comparisons are needed

Medical Robotics

The first generation of surgical robots are already being installed in a number of operating rooms around the world. Robotics is being introduced to medicine because it allows for unprecedented control and precision of surgical instruments in minimally invasive procedures. So far, robots have been used to position an endoscope, perform gallbladder surgery and correct gastroesophogeal reflux and heartburn. The ultimate goal of the robotic surgery field is to design a robot that can be used to perform closed-chest, beating-heart surgery. The use of robotics in surgery will expand over the next decades without any doubt. Minimally Invasive Surgery (MIS) is a revolutionary approach in surgery. In MIS, the operation is performed with instruments and viewing equipment inserted into the body through small incisions created by the surgeon, in contrast to open surgery with large incisions. This minimizes surgical trauma and damage to healthy tissue, resulting in shorter patient recovery time. The aim of this book is to provide an overview of the state-of-art, to present new ideas, original results and practical experiences in this expanding area. Nevertheless, many chapters in the book concern advanced research on this growing area. The book provides critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies. This book is certainly a small sample of the research activity on Medical Robotics going on around the globe as you read it, but it surely covers a good deal of what has been done in the field recently, and as such it works as a valuable source for researchers interested in the involved subjects, whether they are currently “medical roboticists” or not
