Attachable Coolingbis® for Distal Pancreatectomy

Brief Summary

This pilot study evaluates the safety and technical feasibility of a new radiofrequency-assisted device, the Attachable Coolingbis® (ACB), when used during robotic distal pancreatectomy. Distal pancreatectomy, a common operation for tumors of the body or tail of the pancreas, carries a high risk of postoperative pancreatic fistula (occurring in 30-40% of cases) because standard stapling techniques often fail to achieve an effective biological seal of the pancreatic remnant. The ACB device applies radiofrequency energy to coagulate and seal the pancreatic tissue before transection, a technique that has shown promising results in laparoscopic surgery and in preclinical robotic testing. This study adapts the device for use on the robotic surgical platform for the first time in humans. Twenty adult patients undergoing robotic distal pancreatectomy for benign, premalignant, or malignant pancreatic tumors will be enrolled across four Spanish hospitals. All participants will receive the robotic procedure with the ACB device; there is no comparison group, as this is an exploratory, single-arm study. The main goal is to determine whether the device can be used safely and effectively, by monitoring serious adverse events, pancreatic fistula, bleeding, and other surgical complications occurring up to 90 days after surgery. Participants will also be followed for one year to assess longer-term outcomes, including pancreatic function, tumor recurrence, and quality of life.
