About this study

Official title: Prospective, Multicenter, Randomized, Single-blind, Parallel-controlled Clinical Trial Protocol for the Safety and Efficacy of Clinical Applications of the Endoscopic Instrument Control System

This is a prospective, multi-center, randomized, single-blind, parallel-controlled clinical trial to evaluate the safety and efficacy of the Chinese domestic endoscopic instrument control system in clinical treatment.

Read the detailed description

To evaluate the safety and efficacy of the Chinese domestic endoscopic instrument control system in clinical treatment.This clinical trial is a prospective, multi-center, randomized, single-blind, parallel-controlled study. The system used in the experimental group is the endoscopic instrument control system developed by WEGO Surgical Robot Co., Ltd., and the system used in the control group is the da Vinci endoscopic instrument control system developed by Intuitive Surgical. Before patients are enrolled in this clinical study, the researchers will do a detailed screening of the subjects based on the inclusion criteria and the exclusion criteria to determine if the patients are appropriate for the clinical study. Patients who meet the conditions of the study will be required to sign an informed consent form. Then they will be randomly assigned to the experimental group or the control group. To evaluate the primary outcome measures and secondary outcome measures and to observe the incidence of organ and vascular injury. Finally, we evaluate the safety and efficacy of the test product through the comparison of the data obtained from the experimental group and the control group during the treatment.

Being tested
the MicroHand S endoscopic instrument control system, the da Vinci endoscopic instrument control system
Medical subject headings
Gallstones, Cholecystitis

What is being measured

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

  1. surgical success rate

    The surgical success rate is defined as the proportion of successfully operative subjects in the experimental group or the control group.

    Measured: within 24 hours after operation

Secondary outcomes (9)
  1. The breakage rate of gallbladder

    The breakage rate of gallbladder is defined as the proportion of the subjects in the experimental group or the control group with specimen breakage.

    Measured: within 12 hours after operation

  2. Comprehensive Complication Index (CCI)

    CCI is calculated using online tools provided by http://cci.assessurgery.com. Based on the Clavien-Dindo complications grade system (appendix.1), all complications and adverse events after surgical intervention are taken into consideration. The overall incidence is measured on a scale ranging from 0 (no complication) to 100 (death).

    Measured: an average of 5 days after operation

  3. Operative time

    The length of time from the beginning of the operation after the robot installation to the end of the suture of the incision.

    Measured: within 12 hours after operation

  4. Intraoperative bleeding

    The total bleeding volume from the beginning of the operation to the end of the suture of the incision. It can be calculated by measuring the blood volume in the vacuum suction device and weighing the gauze after using them to wipe the bleeding.

    Measured: within 12 hours after operation

  5. Postoperative pain

    Postoperative pain is assessed by visual analogue scale (VAS) 24-26 hours after the operation, ranging from 0 (no pain) to 10 (maximum pain).

    Measured: within 24 hours after operation

  6. Time to first flatus

    The time from the end of the operation to the subject's first flatus after surgery.

    Measured: an average of 2 days after operation

  7. Surgeon's satisfaction

    After the operation, surgeons fill a questionnaire to score the flexibility, intuition and stability of the products, as well as their sense of delay and fatigue when using the products. Each question in the score ranges from 1 to 5 points and the total score is 100.

    Measured: within 12 hours after operation

  8. Installation time

    The time from the power-on of the products to the end of the connection between trocars and the operative arms.

    Measured: preoperation

  9. Hospital stay

    The total hospital days of subjects from admission to discharge.

    Measured: an average of 5 days after operation

Questions about this trial

What is this clinical trial studying?

A study of Gallstone and Cholecystitis, run by The Third Xiangya Hospital of Central South University at 1 site in China.

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 5 inclusion and 12 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: finished, as of the sponsor's last update on 25 Oct 2021. 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 China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

surgical success rate (time frame: within 24 hours after operation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04122261, which also lists 1 linked publication.

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 25 Oct 2021.
