Background:
Minimally invasive surgery (MIS) for gastric cancer is increasingly performed. The purpose of this study is to evaluate trends in utilization of laparoscopic and robotic techniques compared to open surgery as well as utilization based on hospital volume.
Methods:
We used the National Cancer Database to query patients who underwent gastrectomy from 2010 to 2017 for adenocarcinoma. Regression analyses were used to determine associations between MIS and clinical factors, the trend of MIS over time, and survival.
Results:
A total of 18,380 patients met inclusion criteria. The annual rates of MIS increased for all hospital volumes, though lower volume centers were less likely to undergo MIS. MIS was associated with a shorter length of stay compared to open, and robotic gastrectomy had a higher rate of obtaining at least 15 lymph nodes and lower rate of having a positive margin.
Conclusions:
MIS utilization for resection of gastric cancer increased over time, with robotic surgery increasing at a higher rate than laparoscopic surgery. Importantly, this occurred without increased in mortality or sacrificing adequate oncologic outcomes.
