Introduction
The laparoscopic approach to pancreaticoduodenectomy has been recently more frequently reported and is now being performed at multiple centers across the US. While laparoscopic pancreaticoduodenectomy (LPD) has been shown to be safe and feasible, comparing its cost in relation to open pancreaticoduodenectomy (OPD) has not been examined. The aim of this study is to examine the cost of LPD compared with OPD at a single institution over a 3-year time period.
Methods
An institutional database was analyzed to compare patients who underwent OPD and LPD (including Whipple resections and total pancreatectomy) between May 2009 and June 2012. A cost analysis was performed, which included the use the hospital billing database to assess surgical costs, hospital admission costs, and overall cost of the patient’s care during the index admission. The operative costs were further analyzed with respect to OR time and surgical supplies. Standard statistical analysis was performed to assess for significance.
Results
In the study time period, 123 patients underwent pancreaticoduodenectomy, including 48 OPD (39 %) and 75 LPD (61 %). The groups were similar with respect to age, gender, ASA, vein resection, and indication for surgery. In the LPD group, the use of hand assist or conversion to OPD occurred in 3 (4 %) and 10 (13 %) patients, respectively. Additionally, 10 % of the OPD group underwent total pancreatectomy (n = 5), compared to 21 % of the LPD (n = 16). Mean operative time for OPD and LPD was 355 min (range 199–681) and 551 min (range 390–819) respectively (p < 0.0001). Median hospital stay for OPD and LPD was 8 days (range 5–63), and 7 days (range 4–68) respectively (p = 0.5). Morbidity rates were equal at 31 % for the two groups. The LPD group was associated with significantly higher surgical cost due to both increased time and supply cost. However, mean hospital admission cost associated with OPD was greater in comparison to the LPD group, though not significant. The overall total cost of care was similar between the two groups.
Conclusions
LPD is associated with equivalent overall cost compared with OPD. While operating time and supply costs were higher for LPD, this was balanced by decreased cost of the postoperative admission.
