Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training...

INTRODUCTION: Laparoscopic reconstructive surgery is associated with a steep learning curve related to the use of two-dimensional (2D) vision and rigid instruments. With the advent of robotic surgery, three-dimensional (3D) vision, and articulated instruments, this learning curve has been facilitated. We present a hybrid alternative to robotic surgery, using laparoscopy with 3D vision and articulated shears. OBJECTIVE: To compare outcomes of children undergoing pyeloplasty using 3D laparoscopy with articulated instruments with those undergoing the same surgery using standard laparoscopy with 2D vision and rigid instruments...

OBJECTIVE: A major challenge in laparoscopic surgery is the lack of depth perception. With the development and continued improvement of 3D video technology, the potential benefit of restoring 3D vision to laparoscopy has received substantial attention from the surgical community. Despite this, procedures conducted under 2D vision remain the standard of care, and trainees must become proficient in 2D laparoscopy. This study aims to determine whether incorporating 3D vision into a 2D laparoscopic simulation curriculum accelerates skill acquisition in novices...

BACKGROUND: Laparoscopic surgery has become the standard treatment for colorectal cancer. A tumor that does not involve serosa is invisible intraoperatively, and manual palpation of the tumor during laparoscopy is not possible. Therefore, accurate localization of the neoplastic infiltrate remains one of the most important tasks prior to elective laparoscopic surgery. The aim of this study was to evaluate the utility of a magnetic endoscopic imaging (MEI) for precise preoperative endoscopic localization of neoplastic infiltrate within the large bowel...

With the development in past 20 years, the utilization of the laparoscopic surgery, which is the main trend in minimally invasive surgery for colorectal cancer, has tremendously changed. Minimally invasive surgery for colorectal cancer is now at a high level platform after going through the exploration at the very beginning and rapid development in the period of standardizing and promoting the regulations. Nowadays, the unique advantage that the laparoscopy owns is high definition and enlargement of the image, along with the establishment of the key note in series of laparoscopic complete mesocolic excision and the improvement of surgical instruments and methods make the operation skills accurate and normative in exploration of correct plane, high ligation of vessels and protection of nerve during the lymph node dissection of colorectal surgery...

PURPOSE: Surgeons conventionally assume the optimal viewing position during 3D laparoscopic surgery and may not be aware of the potential hazards to team members positioned across different suboptimal viewing positions. The first aim of this study was to map the viewing positions within a standard operating theatre where individuals may experience visual ghosting (i.e. double vision images) from crosstalk. The second aim was to characterize the standard viewing positions adopted by instrument nurses and surgical assistants during laparoscopic pelvic surgery and report the associated levels of visual ghosting and discomfort...

BACKGROUND: Major limitations of conventional 2-dimensional (2D) laparoscopy are a lack of depth perception and spatial orientation. Three-dimensional (3D) laparoscopy was developed to overcome the limitations of the 2D technique. However, it has not been widely accepted due to a lack of conclusive evidence of benefit. The aim of this study was to evaluate the effect of 3D laparoscopy on the operative performance during elective laparoscopic right colectomy. METHODS: A total of 58 consecutive patients underwent laparoscopic colectomy for right-sided colon cancer by a single experienced surgeon between January 2014 and July 2015...

Morgagni hernia is an unusual congenital herniation of abdominal content through the triangular parasternal gaps of the anterior diaphragm. They are commonly asymptomatic and right-sided. We present a case of a bilateral Morgagni hernia resulting in delayed growth in a 10-month-old boy. The presentation was unique due to its bilateral nature and its symptomatic compression of the mediastinum. Diagnosis was made by 3D reconstructed CT angiogram. The patient underwent medical optimization until he was safely able to tolerate laparoscopic surgical repair of his hernia...

Colorectal surgery is rapidly developing in the direction of minimally invasive surgery and functional surgery. New technology and ideas are constantly emerging recently. Laparoscopic colon surgery has already been recommended by NCCN guideline. However, laparoscopic rectal cancer surgery still needs to wait for survival and recurrence rates of long-term follow-up data for verification. In recent years, with the rapid progression of imaging equipment of laparoscope, the new 3D laparoscopic system will process image more quickly, and surgeons can get space depth feeling like open surgery only with a pair of glasses...
