A Regional and National Database Comparison of Colorectal Outcomes

JSLS. Oct-Dec 2018;22(4):e2018.00031. doi: 10.4293/JSLS.2018.00031.


Background and objectives: The traditional open approach is still a common option for colectomy and the most common option chosen for rectal resections for cancer. Randomized trials and large database studies have reported the merits of the minimally invasive approach, while studies comparing laparoscopic and robotic options have reported inconsistent results.

Methods: This study was designed to compare open, laparoscopic, and robotic colorectal surgery outcomes in protocol-driven regional and national databases. Logistic and multiple linear regression analyses were used to compare standard 30-day colorectal outcomes in the Michigan Surgical Quality Collaborative (MSQC) and American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) databases. The primary outcome was overall complications.

Results: A total of 10,054 MSQC patients (open 37.5%, laparoscopic 48.8%, and robotic 13.6%) and 80,535 ACS-NSQIP patients (open 25.0%, laparoscopic 67.1%, and robotic 7.9%) met inclusion criteria. Overall complications and surgical site infections were significantly favorable for the laparoscopic and robotic approaches compared with the open approach. Anastomotic leaks were significantly fewer for the laparoscopic and robotic approaches compared with the open approach in ACS-NSQIP, while there was no significant difference between robotic and open approaches in MSQC. Laparoscopic complications were significantly less than robotic complications in MSQC but significantly more in ACS-NSQIP. Laparoscopic 30-day mortality was significantly less than for the robotic approach in MSQC, but there was no difference in ACS-NSQIP.

Conclusion: Minimally invasive colorectal surgery is associated with fewer complications and has several other outcomes advantages compared with the traditional open approach. Individual complication comparisons vary between databases, and caution should be exercised when interpreting results in context.
