To explore the security, clinical outcomes and short-term effects of robot-assisted pancreaticoduodenectomy ( RPD ).

Perioperative clinical data of 23 consecutive pancreaticoduodenectomy (PD)procedures performed from Jan. to Dec.2016 by the single operator in Tianjin Medical University Cancer Hospital were retrospective analyzed, among which 10 patients underwent RPD ( RPD group) while 13 patients received open pancreaticoduodenectomy (OPD group). Perioperative outcomes were compared within these two groups.

All of the patients have been through the surgery and then recovered successfully without dead. No significant difference had been found between the two groups in age, sex, BMI, ASA score .The RPD group had significantly longer operative time [ (429 ± 77.5) min vs (288.5 ± 35.8) min, P< 0.001) ], higher hospitalization expense[(16.2 ± 2.6) ten thousand yuan vs (12.7 ± 2.8) ten thousand yuan, P= 0.006) ], reduced estimated blood loss [( 105.0 ± 72.5) ml vs ( 276.9 ± 136.3) ml, P= 0.002) ], earlier ambulation [( 1.8 ± 0.7)d vs ( 2.9 ± 1.0) d, P= 0.010)], shorter postoperative hospital stay[(16.0 ± 6.0)d vs (25.7 ± 14.5)d, P=0.043)]. Moreover, 1 case (10%)in RPD group and 2 cases(15.4%) in OPD group experienced pancreatic fistular , there is no significant difference in pancreatic fistular rate(P=0.710).

Modified Blumgart anastomosis in robot-assisted pancreaticoduodenectomy serves as a safe and feasible operation resulting in less trauma and quicker recovery.It is worth promoting and perfecting in future.
