Background
Based on previous meta-analyses and comparative evidence, robotic approach might lead to a higher or at least similar spleen-preservation rates when comparing with laparoscopic approach in spleen preserving distal pancreatectomy (SPDP) for benign or low-grade malignant pancreatic tumors1–3. But high-quality evidence lacks and controversy exists. Therefore, we planned to initiate a prospective, patient-blinded, randomized, controlled trial (RCT) to compare robotic assisted spleen preserving distal pancreatectomy (RSPDP) with laparoscopic spleen preserving distal pancreatectomy (LSPDP), with special consideration to the success rate of splenic vessel-preserving (Kimura) approach, as well as perioperative variables, and cost analysis.
Methods
Patients with benign or low-grade malignant pancreatic tumors are potential candidates for this RCT. Enrolled participants are randomized into RSPDP (observational arm) or LSPDP (control arm) groups as a ratio of 1:1. The primary outcome is the success rate of splenic vessel-preserving (Kimura) approach. The secondary outcomes include total success rate of spleen preserving (Kimura and Warshaw approaches), intraoperative variables, time to functional recovery, postoperative complications, mortality, and cost/efficacy analysis.
Discussion
We plan to conduct a randomized controlled trial to detect the potential advantages of robotic approach in spleen vessels preservation compared with traditional laparoscopic approach. RSPDP may improve spleen vessels preservation rate in selected patients.
