The possible advantages of laparoscopic (assisted) total gastrectomy (LTG) versus open total gastrectomy (OTG) have not been reviewed systematically. The aim of this study was to systematically review the short-term outcomes of LTG versus OTG in the treatment of gastric cancer. A systematic search of PubMed, Cochrane, CINAHL, and Embase was conducted. All(More)
Robotic surgery systems were introduced to overcome the disadvantages of endoscopic surgery. The goal of this study was to assess whether robot assistance could support endoscopic surgeons in performing a complex endoscopic task. Five experienced endoscopic surgeons performed end-to-end anastomosis on post-mortem porcine small intestine. The procedure was(More)
Introduction: Robotic telemanipulation systems have been introduced recently to enhance the surgeon's dexterity and visualization in videoscopic surgery in order to facilitate refined dissection, suturing, and knot tying. The aim of this study was to demonstrate the technical feasibility of performing a safe and efficient robot-assisted handsewn(More)
Robot-assisted surgical systems have been introduced to improve the outcome of minimally invasive surgery. These systems also have the potential to improve ergonomics for the surgeon during endoscopic surgery. This study aimed to compare the user’s mental and physical comfort in performing standard laparoscopic and robot-assisted techniques. Surgical(More)
PURPOSE To explore the value of diffusion-weighted magnetic resonance imaging (DW-MRI) for the prediction of pathologic response to neoadjuvant chemoradiotherapy (nCRT) in esophageal cancer. MATERIAL AND METHODS In 20 patients receiving nCRT for esophageal cancer DW-MRI scanning was performed before nCRT, after 8-13 fractions, and before surgery. The(More)
Laparoscopic surgery offers patients distinct benefits but is not without its disadvantages to surgeons in terms of maneuverability and visualization. Robotic telemanipulation systems were introduced with the objective of providing a solution to the problems in this field of surgery. The feasibility of robot-assisted surgery was assessed by performing 35(More)
BACKGROUND Robotic systems for minimally invasive surgery may be of added value during extensive dissection and suturing in confined spaces, such as laparoscopic Nissen fundoplication (LNF). The purpose of this trial was to compare standard LNF with robot-assisted Nissen fundoplication (RNF). METHODS Between 2003 and 2005, 50 patients with confirmed(More)
BACKGROUND Laparoscopic Nissen fundoplication (LNF) is currently considered the surgical approach of choice for gastro-oesophageal reflux disease (GORD). Laparoscopic Toupet fundoplication (LTF) has been said to reduce troublesome dysphagia and gas-related symptoms. A systematic review and meta-analysis of randomized clinical trials (RCTs) was performed to(More)
During thoracoscopic oesophageal surgery, we observed not previously described fascia-like structures. Description of similar structures in rectal cancer surgery was of paramount importance in improving the quality of resection. Therefore, we aimed to describe a new comprehensive concept of the surgical anatomy of the thoracic oesophagus with definition of(More)
BACKGROUND Reconstruction of the infrarenal aorta for aneurysms is routinely performed through laparotomy. A less invasive videoscopic approach has not gained wide acceptance due to technical difficulties. Robotic systems could potentially improve imaging of the operative field and surgeon's dexterity during videoscopic surgery and therefore might(More)
