Introduction : Operation plan for pancreatic tumor used to be divided in four main type，pancreaticoduodenectomy（PD），central pancreatectomy， distal pancreatectomy（DP） and pancreatic enucleation .To evaluate the value of da Vinci robotic surgery system in pancreatectomy.

Methods : the clinical data of a consecutive of 1000patients who underwent robotic-assisted pancreatectomy from November, 2011 to September 2017 were retrospectively reviewed. All the operations were performed by the same team, which mainly approach in Da Vinci robotic system Si. The demographic characteristics, intraoperative blood loss, operative duration, post-operative hospital stay, blood transfusion details, and conversion rate were all analyzed.

Results : A total of 1000 patients were included in this study, with an average age of 54.0, and 486 cases of them were male. The average operative time was 3.5 hours (2-7 h), the estimated blood loss was 100ml (20-1200 ml), and the postoperative hospital stay was 9.3 days in average. Overall complication morbidity was 7.9% (79/1000) and 6.7%(67/1000) cases suffered from grade B-C Pancreatic fistula, with the conversion rate of 3.2% and 30-Day mortality rate of 0.42%.

Conclusions : Robotic pancreatectomy could be successfully performed with the assistance of da Vinci surgery system, the operative duration, post-operative hospital stay and intraoperative blood loss were satisfying, with very patients died in 30 days and very operations converted.
