RESUMO
BACKGROUND: As robotic colorectal surgery continues to advance in conjunction with improved recovery protocols, we began implementing robotic surgery (RS) as an option for emergent diverticulitis surgery. Our hospital system utilizes the Da Vinci Xi system, and staff are required to undergo training, making emergent colorectal surgery a feasible option. However, it is essential to determine the safety with reproducibility of our experiences. METHODS: A de-identified retrospective review was performed of Intuitive's national database which obtained data from 262 facilities from January 2018 through December 2021. This identified over 22,000 emergent colorectal surgeries. Of those, over 2500 were performed for diverticulitis in which 126 were RS, 446 laparoscopic surgery (LS), and 1952 open surgery (OS). Clinical outcome metrics including conversion rates, anastomotic leaks, intensive care unit (ICU) admissions, length of stay, mortality, and readmissions were obtained. The cohort was defined by patients who were seen in the emergency department (ED) with diverticulitis and proceeded to have a sigmoid colectomy within 24 h of ED arrival. RESULTS: RS was associated with increased operating time (RS 262, LS 207, OS 182 min), but data has shown many benefits of emergent RS compared to OS. We identified significant decreases in ICU admission rates (OS 19.0%, RS 9.5%, p = 0.01) and anastomotic leak rates (OS 4.4%, RS 0.8%, p = 0.04), with borderline improvement in overall length of stay (OS 9.9, RS 8.9 days, p = 0.05). When compared with LS, RS showed many comparable results. However, RS witnessed a statistically significant improvement in anastomotic leak rates (LS 4.5%, RS 0.8%, p = 0.04). Importantly, there was a striking difference in conversion rates to OS. LS converted over 28.7% of cases to OS, whereas RS only converted 7.9%, p = 0.000005. CONCLUSION: Given these findings, RS is another MIS tool that could be a safe and feasible option for the acute management of emergent diverticulitis.
