Plain English Summary

Background and study aims
Minimal access surgery (also known as keyhole surgery) has been carried out for over 30 years at hospitals around the world. It is well-established and has several advantages over other surgical methods, such as a shorter recovery time, fewer complications and shorter hospital stays. Thousands of minimal access operations are carried out each year. Recently it has been possible to use robot arms to help carry out minimally invasive operations.
This study is being run to assess the safety and competence of the Versius® Surgical Robotic System in performing operations for removal of the gall bladder. Versius is a robot designed to be used in minimal access surgery. It has been developed and built by CMR Surgical Limited, a UK based and registered company. The system allows a surgeon to stand or sit a console to control a set of robotic arms which are holding instruments needed to perform minimal access surgery.

Who can participate?
All patients aged 18 years and above, eligible for surgery with Versius, as decided by the operating surgeon.

What does the study involve?
All participants will have gall bladder removal surgery as usual and as decided by their healthcare professionals.

What are the possible benefits and risks of participating?
There are no direct benefits to participants. The information collected may benefit patients in the future. The risks from participating in this study are similar to those associated with any minimal access (keyhole) gall bladder removal surgical procedure.

Where is the study run from?
CMR Surgical (UK)

When is the study starting and how long is it expected to run for?
March 2022 to January 2023

Ethics approval(s)Approved 12/08/2022, Institutional Ethics Committee, Devki Devi Foundation (Service Floor, Office of Ethics Committee, East Block, Max Super Speciality Hospital, Saket 2, Press Enclave Road, Saket, New Delhi, 110017, India; +91 9873003832; Kamal.Fotedar@maxhealthcare.com), ref: CT/MSSH/DDF/SKT-2/IEC/MAMBS/22-08
ConditionRobot assisted cholecystectomy
InterventionA prospective single arm cohort study for robot assisted laparoscopic cholecystectomy, with the Versius Surgical Robotic System. Use of Versius, patient care and all follow-ups will be as per standard clinical practice, and GCP and regulatory requirements will be strictly followed.
Intervention typeDevice
Pharmaceutical study type(s)
PhasePhase II/III
Drug / device / biological / vaccine name(s)Versius Surgical Robotic System
Primary outcome measurePrimary efficacy outcome:
Rate of successful completion of robot assisted surgery without unplanned conversion to other laparoscopic or open surgery, as recorded on the data entry platform

Primary safety outcome:
Incidence of serious adverse events, recorded on the data entry platform at any time between commencement of surgery (intraoperative) to the end of the trial (postoperative, between incidence of surgery to 30 days after surgery)
Secondary outcome measures1. Operative time measured in minutes from incision to skin closure at the facility, collected as procedural data from medical records
2. Estimated blood loss (in ml) during surgery, collected as procedural data from medical records
3. Blood transfusion during surgery (number of blood transfusion products used (if any)) collected from patient’s medical records
4. Any intra-operative complications during surgery collected as procedural data and from patient’s medical records
5. Return to operating room within 24 hours after surgery, measured using medical records
6. Length of hospital stay in days (from date of procedure to date of discharge), measured using medical records
7. Incidence of readmission to hospital within 30 days after surgery, measured using medical records and at 30-day follow-up
8. Incidence of reoperation within 30 days after surgery, measured using medical records and at 30-day follow-up
9. 30-day mortality from medical records and/or follow-up visit/call during the 30-day follow up
10. Histopathology results of any surgically removed specimens from medical records available at day of discharge and at 30 day follow up
11. Incidence of device deficiencies and use errors regardless of relationship to an adverse
event, collected as procedural and/or adverse event data and from patient medical records
12. All adverse events, including postoperative complications reported using Clavien-Dindo Classification and according to medical records, up to 30 days' follow up
13. Device performance data including unplanned instrument usage, clashes, collision detection, alarms, collected as procedural data during surgery
