Exploring the application of da Vinci single-channel SP robot in hepatopancreas surgery.

Using the da Vinci SP robotic platform, enucleation of pancreatic tumor, left lateral lobe resection, and enlarged left lateral lobectomy + regional lymph node dissection were performed on one patient with pancreatic tail cystadenoma, one patient with left lateral hepatic hepatic carcinoma, and one patient with mixed liver cancer in left hepatic lobe.

All 3 patients successfully underwent single-channel robotic surgery. The installation time were 20, 14 and 9 minutes, the operation time were 55, 49 and 76 minutes, the total operation time were 100, 83 and 105 minutes, the blood loss were 5, 10 and 20 ml, and the postoperative visual analogue pain scale were 3/10, 3/10 and 3/10, the visual analogue pain scale on the first day after surgery were 1/10, 1/10 and 1/10, all 3 patients had no complications.

Preliminary surgical experience suggests that single-channel robotic surgery is safe and feasible in simple hepatobiliary and pancreatic surgery, and has significant advantages over traditional single-port surgery. However, further experience accumulation and comparative studies are needed to demonstrate its clinical value and clarify surgical indications.
