摘要

Background

In this single-center retrospective study, we compare the 30 day perioperative outcomes for patients undergoing robotic vs laparoscopic bariatric surgery. Primary outcomes are serious events as defined by MBSAQIP including leak, infection, bleeding, among others; secondary outcomes include procedure time, length of stay (LOS), and readmission.

Methods

We compared 5,690 patients (2011–2023). The robotic group consisted of primary sleeves (n = 2122), primary bypasses (n = 462), conversion to bypass (n = 240), and conversion to sleeve (n = 117). The laparoscopic group consisted of primary sleeves (n = 2122), primary bypasses (n = 462), conversion to bypass (n = 48), and conversion to sleeves (n = 117). We compared outcomes using propensity score matching to minimize confounding variables due to patient selection.

Results

In the primary outcome, blood loss was significantly less in the primary robotic bypass and sleeve groups (p < 0.01). The robotic conversion groups also had less blood loss, however it was not significant (bypass p 0.012, sleeve p = 0.45).

No other statistically significant difference in adverse events was noted.

For secondary outcomes, LOS was statistically significantly shorter in the primary robotic bypass, primary robotic sleeve, and robotic conversion to sleeve (p < 0.001). In the conversion to bypass, the LOS was shorter but not statistically significant (p = 0.071).

The procedure time was statistically significantly longer in all robotic groups (p < 0.001) except the conversion to bypass (p = 0.77).

There was no statistically significant difference in the readmission between the two groups.

Conclusions

As the largest single-center study comparing robotic vs laparoscopic perioperative outcomes, we found robotic bariatric surgery to have lower blood loss, shorter LOS, and longer procedure times. There were no other statistically significant differences in adverse events.
