Abstract
BACKGROUND: Minimally invasive pancreaticoduodenectomy (PD) remains one of the most challenging abdominal procedures, and its application is poorly reported in the literature so far. To date, few data are available comparing a minimally invasive approach to open PD. The aim of the present study is to compare the robotic and open approaches for PD at a single institution. METHODS: Data from 83 consecutive PD procedures performed between January 2002 and May 2010 at a single institution were retrospectively reviewed. Patients were stratified into two groups: the open group (n = 39; 47%) and the robotic group (n = 44; 53%). RESULTS: Patients in the robotic group were statistically older (63 years of age versus 56 years; p = 0.04) and heavier (body mass index: 27.7 vs. 24.8; p = 0.01); and had a higher American Society of Anesthesiologists (ASA) score (2.5 vs. 2.15; p = 0.01) when compared to the open group. Indications for surgery were the same in both groups. The robotic group had a significantly shorter operative time (444 vs. 559 min; p = 0.0001), reduced blood loss (387 vs. 827 ml; p = 0.0001), and a higher number of lymph nodes harvested (16.8 vs. 11; p = 0.02) compared to the open group. There was no significant difference between the two groups in terms of complication rates, mortality rates, and hospital stay. CONCLUSIONS: The authors present one of the first studies comparing open and robotic PD. While it is too early to draw definitive conclusions concerning the long-term outcomes, short-term results show a positive trend in favor of the robotic approach without compromising the oncological principles associated with the open approach.
