Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with radiologically suspected or confirmed incidental gallbladder cancer who are fit for radical cholecystectomy.

Probably not a fit

Patients with previous extensive upper abdominal surgery, pregnancy, or intraoperative findings requiring different surgical approaches will not benefit from this study.

What this trial studies

The Robocop trial is an international, multi-centre, single-blinded, randomized controlled trial comparing robotic-assisted radical cholecystectomy to open resection for patients with suspected or confirmed gallbladder cancer. Patients will be randomly assigned in a 1:1 ratio to either surgical approach within an enhanced recovery setting. The primary goal is to evaluate the time to functional recovery, while secondary outcomes include hospital stay duration, resection margins, lymph node retrieval, postoperative complications, quality of life, and associated costs.

Why it matters

Potential benefit: If successful, this approach could lead to faster recovery times and improved outcomes for patients undergoing surgery for gallbladder cancer.

How similar studies have gone: Previous studies have shown promising results with robotic-assisted surgeries, suggesting potential benefits, although this specific approach is being tested for the first time in this context.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patient with radiologically suspected or confirmed (≥T1b) incidental gallbladder cancer after cholecystectomy with an indication of radical cholecystectomy, without the need for resection of extrahepatic bile ducts, as decided at a multidisciplinary team conference.
* Patient sufficiently fit to undergo radical cholecystectomy according to surgeon and anaesthesiologist.

Exclusion Criteria:

* Previous extensive surgery in the upper abdomen (for example open liver surgery)
* Pregnancy
* Intraoperative findings of dissemination (patient is then excluded after randomization)
* Intraoperative findings of the need to perform resection of extrahepatic bile ducts (patient is then excluded after randomization).
* Intraoperative findings leading to a simple cholecystectomy only (patient is then excluded after randomization)
