About this study

Official title: A Pilot Study Evaluating the Feasibility and Usability of the LaparoGuard System During Laparoscopic Surgical Procedures

LaparoGuard is intended as an adjunctive safety system for laparoscopic surgery. The system allows surgeons to virtually annotate a safe anatomical volume inside the body cavity of the patient during a laparoscopic surgery. The surgeon then receives notification throughout the procedure whenever a tracked rigid instrument has exited that volume. This open label, prospective, feasibility, single site, multi-investigator trial will evaluate the feasibility and usability of the LaparoGuard system during laparoscopic surgical procedures.

Read the detailed description

PHASE 1) LaparoGuard will be used as an adjunctive tool for maintaining safety during procedures performed by expert surgeons. The pre-operative instructions for use will be evaluated along with ease of procedural setup, as reported by pre-operative nurses. The intraoperative instructions for use will be evaluated along with system usability, as reported by the expert surgeons. The perceived clinical utility will be judged by expert surgeons. Postoperatively, the system data will be reviewed. This phase will include 4-6 subjects.

PHASE 2) Novice surgeons will conduct procedures alongside expert surgeons. Expert surgeons will establish the safe zone. LaparoGuard will record all deviations, speed and smoothness of tip movements. The training utility of LaparoGuard will be assessed by both the expert and novice surgeons. This phase will include 4-6 subjects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Procedural Success

    For each surgical procedure conducted, the case will be defined as a technical success if: the surgical team is able to complete the procedure without needing to turn off the LaparoGuard system. Failure will be if the operator deems it necessary to stop utilizing the LaparoGuard system and resort to the standard (non-annotated) endoscopic camera feed. Potential reasons for doing so may be device reporting errors, such as the LaparoGuard system consistently incorrectly reporting that a surgical tool has exited the safe zone.

    In emergency situations, such as changes in medical condition unrelated to use of the LaparoGuard system, the operator may also deem it necessary to resort to the standard-of-care; however, these situations will not be judged as failures and the case data will be utilized for study purposes up until that point.

    Measured: Intraoperative

Secondary outcomes (6)
  1. Pre-operative LaparoGuard system setup time

    The amount of time taken to setup the LaparoGuard system by the surgical nurses will be recorded

    Measured: Baseline

  2. Usability reported pre-operatively by nurses

    Following setup of the LaparoGuard system preoperatively, but prior to bringing the patient into the surgical suite, study staff will conduct a short interview with the surgical nurses to evaluate their comfort and ease with the system setup procedures. If any use errors or confusion were observed by the study staff, these shall be discussed in depth. Comments reported by the nurses on difficulties encountered and potential simplifications to the procedures will be recorded.

    Measured: Baseline

  3. Safe zone deviations

    The total number of safe zone deviations as well the total time each instrument was outside the safe zone will be tracked and evaluated.

    Measured: Intraoperative

  4. Usability reported post-operatively by surgical team

    Following completion of each surgical procedure, study staff will conduct a short interview with the surgical team to evaluate the ability of the team to interpret the LaparoGuard output, the safe zone and respond to any information provided by system.

    Measured: Intraoperative

  5. Clinical utility reported by expert surgeons

    Following the completion of all 10 cases, study staff will conduct interviews with the expert surgeons to evaluate their perceived clinical utility of the LaparoGuard system. A qualitative discussion will held around the particular clinical situations in which LaparoGuard may be most useful. Study staff will also record any potential insights by the surgeons on future features which may be incorporated to improve the clinical utility of LaparoGuard.

    Measured: 2 months

  6. Training utility reported by novice and expert surgeons

    Following the completion of all 10 cases, study staff will conduct interviews with the expert and novice surgeons to evaluate their perceived training utility of the LaparoGuard system. Quantitative rating scales will be used and qualitative discussion will held around the particular training situations in which LaparoGuard may be most useful. Study staff will also record any potential insights by the expert or novice surgeons on future features which may be incorporated to improve the training utility of LaparoGuard.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing LaparoGuard System in people with Laparoscopic Surgical Procedures, run by Mariner Endosurgery at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 15 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Procedural Success (time frame: Intraoperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2023; AzTrials last refreshed its copy on 1 Nov 2026.
