3-dimensional Versus 2-dimensional Laparoscopy of Ovarian Cyst

Status Completed

Clinical Trial Summary

Lack of depth perception and spatial orientation are drawbacks of laparoscopic surgery. The advent of the three-dimensional (3D) camera system enables surgeons to regain binocular vision. The aim of this study was to gain subjective and objective data to determine whether 3D systems are superior to two-dimensional (2D) systems in terms of surgical outcomes.

Clinical Trial Description

Elective laparoscopic ovarian cystectomy is established as the treatment of choice for benign ovarian cysts. The advantages of laparoscopic surgery over conventional open surgery are less pain, shorter recovery time, shorter hospital stay, and consequently faster return to normal activity as well as better cosmetic effects. However, laparoscopic surgery is more challenging compared with open surgery, partly because surgeons must operate in a three-dimensional (3D) space through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception and consequently more cognitive workload on the surgeon. In traditional 2D laparoscopic procedures, the surgeon has to mentally transform and process the 2D image into a 3D image using motion parallax through movement of the laparoscope, relative position of instruments, and shading of light and dark. During the past 3 decades, 3D imaging systems have been introduced in and attempt to improve in-depth perception and spatial orientation during minimally invasive surgery. The anticipated advantages for the surgeon are greater accuracy and speed in manual skills, translating to decreased operative time, a reduced learning curve, and enhanced safety.

Nevertheless, studies, to date, examining the potential advantages and disadvantages of 3D versus 2D imaging systems have produced contradictory results. Moreover, there have been no studies exploring the advantage of 3D imaging system in patients undergoing laparoscopic ovarian cystectomy. The aim of this study was to gain subjective and objective data to determine whether 3D imaging systems in the treatment of ovarian cyst are superior to 2D systems in terms of surgical outcomes. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
