Background: Laparoscopic liver resection has been gaining momentum, and it has become an accepted practice after the two international consensus conferences where experts worked up guidelines to standardize this approach and improve its safety. However, most laparoscopic hepatectomies were performed in patients with liver metastases. The concurrent presence of liver cirrhosis with hepatocellular carcinoma (HCC) poses a great challenge to clinicians trying to establish a routine use of laparoscopic liver resection for HCC...

BACKGROUND: Augmented reality (AR) technology is used to reconstruct three-dimensional (3D) images of hepatic and biliary structures from computed tomography and magnetic resonance imaging data, and to superimpose the virtual images onto a view of the surgical field. In liver surgery, these superimposed virtual images help the surgeon to visualize intrahepatic structures and therefore, to operate precisely and to improve clinical outcomes. DATA SOURCES: The keywords "augmented reality", "liver", "laparoscopic" and "hepatectomy" were used for searching publications in the PubMed database...

Three-dimensional (3D) laparoscopic surgical systems have been developed to account for the lack of depth perception, a known disadvantage of conventional 2-dimensional (2D) laparoscopy. In this study, we retrospectively compared the outcomes of total laparoscopic hysterectomy (TLH) with 3D versus conventional 2D laparoscopy. From November 2014, when we began using a 3D laparoscopic system at our hospital, to December 2015, 47 TLH procedures were performed using a 3D laparoscopic system (3D-TLH). The outcomes of 3D-TLH were compared with the outcomes of TLH using the conventional 2D laparoscopic system (2D-TLH) performed just before the introduction of the 3D system...

PURPOSE: 3D imaging is an upcoming technology in laparoscopic surgery, and recent studies have shown that the modern 3D technique is superior in an experimental setting. However, the first randomized controlled clinical trial in this context dates back to 1998 and showed no significant difference between 2D and 3D visualization using the first 3D generation technique, which is now more than 15 years old. METHODS: Positive results measured in an experimental setting considering 3D imaging on surgical performance led us to initiate a randomized controlled pragmatic clinical trial to validate our findings in daily clinical routine...

BACKGROUND: Hysterectomy is one of the most common surgical procedures for women of reproductive age. Laparoscopy was introduced in the 1990es and is today one of the recommended routes of surgery. A recent observational study showed that operative time for hysterectomy was significantly lower for 3-dimensional compared to conventional laparoscopy. Complication rates were similar for the two groups. No other observational studies or randomized clinical trials have compared 3-dimensional to conventional laparoscopy in patients undergoing total hysterectomy for benign disease...

In the late 1980s the first laparoscopic cholecystectomies were performed prompting a sudden rise in technological innovations as the benefits and feasibility of minimal access surgery became recognised. Monocular laparoscopes provided only two-dimensional (2D) viewing with reduced depth perception and contributed to an extended learning curve. Attention turned to producing a usable three-dimensional (3D) endoscopic view for surgeons; utilising different technologies for image capture and image projection. These evolving visual systems have been assessed in various research environments with conflicting outcomes of success and usability, and no overall consensus to their benefit...

BACKGROUND: Usually laparoscopy is performed by means of a 2-dimensional (2D) image system and multiport approach. To overcome the lack of depth perception, new 3-dimensional (3D) systems are arising with the added advantage of providing stereoscopic vision. To further reduce surgery-related trauma, there are new minimally invasive surgical techniques being developed, such as LESS (laparoendoscopic single-site) surgery. The aim of this study was to compare 2D and 3D laparoscopic systems in LESS surgical procedures...

With the widespread introduction of minimally invasive surgery (MIS) in late 1987 by laparoscopic cholecystectomy, the practice and expectation of general surgery were changed forever. As the development of scientific technology, new techniques of MIS have sprung up all around the world. 3D laparoscopy surgery, natural orifice transluminal endoscopic surgery, da Vinci surgical system and other new technologies also need time to be verified, and this is the only way all new things should get though. They are very unique in their own right, and all have advantages and disadvantages...

INTRODUCTION: Conventional two-dimensional (2D) laparoscopy systems have the drawback of poor depth perception and spatial orientation. Three-dimensional (3D) laparoscopic systems have stereoscopic vision in which depth perception is achieved by different unique images received by each eye. We evaluated 3D laparoscopy in comparison with conventional 2D laparoscopy in urological procedures in a prospective randomized study. MATERIALS AND METHODS: Over a 19 month study period, 108 patients scheduled to undergo various urological procedures were randomized to either conventional 2D or 3D laparoscopy (2D n = 53; 3D n = 55)...
