Laparoscopic Versus Robot-assisted Left-sided Pancreatectomy for Benign and Pre-malignant Lesions (DIPLOMA-3)

This study is comparing two minimally invasive surgical approaches for removing part of the pancreas: traditional laparoscopic surgery (using a camera and small instruments) versus robot-assisted surgery. The operation is for benign or pre-cancerous conditions on the left side of the pancreas. Researchers want to know which approach leads to better outcomes. **You may be eligible if...** - You are 18 or older - You need elective surgery to remove part of the left side of your pancreas due to a benign or pre-cancerous condition - Both laparoscopic and robotic approaches are technically feasible for your case - You are fit for surgery as assessed by your surgical team **You may NOT be eligible if...** - Your tumor is suspected to be pancreatic ductal adenocarcinoma (the most common and aggressive form of pancreatic cancer) - Your cyst or tumor is larger than 8 cm - Surgery would require removing other organs besides the pancreas and spleen - Your tumor involves or is touching major blood vessels - You are pregnant or have a BMI over 40 Talk to your doctor to see if this trial is right for you.
