Comparison of the da Vinci Skills Simulator and the LapSim Laparoscopy Simulator for Conventional Laparoscopic Skills Improvement: a Prospective, Randomized Trial

Virtual reality surgical simulators (VRSS) are gaining popularity for general surgery training, both for conventional laparoscopic and robotically-assisted surgery. Although numerous studies have analysed the impact of VRSS training on surgical skills, there is a lack of data regarding the comparison of robotic VRSS (RVRSS) and laparoscopic VRSS (LVRSS) training on conventional laparoscopic skills among subjects with no prior surgical experience. The hypothesis of the present study is that RVRSS could improve conventional laparoscopic skills as much as laparoscopic LVRSS among naïve subjects

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Exercises times
Time Frame: Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Time to realize each training exercise as well as the final evaluation exercise
Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Objects drops
Time Frame: Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Number of time objects were unwillingly dropped during each training exercise as well as the final evaluation exercise
Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Objects out of view
Time Frame: Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Number of times one or both instruments or objects used for the exercises were out of the viewing field during each training exercise as well as the final evaluation exercise
Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Instruments collisions
Time Frame: Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
Number of collisions between the different instruments used to perform each training exercise as well as the final evaluation exercise
Within 1 day after randomization / data will be presented after completion of the study (an average of 9 months)
