About this study

Official title: Pilot Study of Single-Port Robot-Assisted Surgery Using Da Vinci SP Surgical System for Patients With Complex Cholelithiasis and Choledocholithiasis

A prospective, interventional, single arm study to investigate clinical feasibility of single-stage cholecystectomy and common bile duct exploration using da Vinci SP Surgical System (robotic surgery)

Read the detailed description

Cholelithiasis (gallstones) is a common disease of digestive tract in adults. It has been reported that 5-10% or 2 million of Taiwanese adults have gallstones according to National Health Insurance Administration.

Laparoscopic cholecystectomy is deemed a surgical standard of care for its safety, effectiveness, and benefits: less post-operative pain, faster recovery, shorter hospital stay, and better cosmesis. However, the advantages of da Vinci surgical system include enhanced vision, wristed instruments, and dexterity of control.

Robotic cholecystectomy by single-port SP system is associated with shorter operation time, shorter dissection time, and less post-operative pain.

Further improvement in robotic cholecystectomy with CBDE regarding cosmesis and patient satisfaction could be made by adopting da Vinci SP system which preserves enhanced vision and instrument dexterity with only one access port. So far there is no published data on robotic cholecystectomy with CBDE using da Vinci SP. Current study is set forth to evaluate technical feasibility and clinical outcome of robotic biliary surgery using da Vinci SP Surgical System for patients with complex cholelithiasis.

What is being measured

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

  1. Incidence of conversion rate

    The primary performance endpoint will be assessed as the ability to successfully completed the planned procedure with da Vinci SP System, with no conversion to alternative surgery including open surgery or laparoscopy.

    Measured: During Surgery

Secondary outcomes (1)
  1. Incidence of Treatment Emergent Adverse Events

    The safety endpoint will be assessed as the incidence of all intra-operatvie and post-operative adverse events that occur through the follow up period.

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing da Vinci SP Surgery System in people with Cholelithiasis and Choledocholithiasis, run by National Taiwan University Hospital at 1 site in Taiwan.

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 8 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 17 Sep 2026. 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 Taiwan. 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?

Incidence of conversion rate (time frame: During Surgery). 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 17 Sep 2026.
