Background
Minimally invasive pancreaticoduodenectomy (MIPD) is being performed with increasing frequency for pancreatic cancer, but the most oncologically efficacious surgical platform, whether robotic or laparoscopic, is yet to be determined. Currently, there are no national studies comparing the oncological outcomes between robotic (RPD) and laparoscopic (LPD) pancreaticoduodenectomy.
Methods
This was a retrospective study using the National Cancer Database between 2010 and 2013. We compared the perioperative, pathological, and mid-term oncological outcomes between RPD and LPD.
Results
There were 1623 MIPD cases, of which 90% were LPD and 10% were RPD. Most LPD (63%) and RPD (51%) cases were performed at institutions with a volume of ≤ 5 MIPDs per year. There were no differences in patient- and tumor-related factors between the groups. The majority of treated tumors were adenocarcinoma (90.1% for RPD and 89.1% for LPD). RPDs were more likely to be performed at academic centers (89.1%) compared to LPDs (68.1%, P < 0.001) and at higher-volume centers (median MIPD/year of 4.7 for RPD vs 3.6 for LPD, P < 0.001). There was no difference in the median number of examined lymph nodes, margin status, median length of stay, 90-day mortality, or 30-day readmission between groups. There was no difference in median overall survival for pancreatic adenocarcinoma between LPD (20.7 months) and RPD (22.7 months; log-rank P = 0.445). The 1- and 3-year overall survival rates were 74 and 31% for LPD and 71 and 33% for RPD.
Conclusion
In this national cohort of patients, LPD and RPD were associated with equivalent perioperative, pathological, and mid-term oncological outcomes.
