A systematic review on robotic pancreaticoduodenectomy

Background: Robotic surgery might have several advantages in respect of the laparoscopic approach since might make more feasible the execution of a complex procedure such as pancreaticoduodenectomy (PD). The aim of the present systematic review is to evaluate the current state of the literature on robotic PD. Methods: A systematic literature search was performed, from January 1st 2003 to July 31st 2012, for studies which reported PDs performed for neoplasm and in which at least one surgical reconstructive or resective step was robotically performed. Results: Thirteen studies, representing 207 patients, met the inclusion criteria. The definition of the robotic approach was heterogeneous since the technique was defined as robotic, robotic-assisted, robot-assisted laparoscopic and robotic hybrid. Resection and reconstruction steps of robotic PD were also heterogeneous combining sequentially different approaches: totally robotic technique, laparoscopicerobotic resection and robotic reconstruction, laparoscopic resection and robotic reconstruction, hand port-assisted laparoscopic resection and robotic reconstruction, laparoscopicerobotic resection and reconstruction through mini-laparotomy. As regard the type of PD 66% were classic Whipple operations and 34% pylorus-preserving pancreatoduodenectomies. The management of pancreatic stump was a pancreaticogastrostomy in 23%, end-to-side pancreaticojejunostomy in 67%, and fibrin glue occlusion of the main pancreatic duct in 10% of cases. The overall procedure failure (rates of conversion to open surgery) was 14%. The overall morbidity rate was 58% and the reoperation rate was 7.3%. Conclusions: There have been an increasing number of recent case series suggesting increased utilization of robotic PD over the past decade. The technical approach is heterogenous. For highly selected patient, robotic PD is feasible with similar morbidity and mortality compared to open or purely laparoscopic approaches. Data on cost analysis are lacking and further studies are needed to evaluate also the cost-effectiveness of the robotic approach for PD in comparison to open or laparoscopic techniques. The current state of the art analysis on robotic DP can be also useful in planning future trials. (C) 2013 Elsevier Ltd. All rights reserved.
