Abstract

Diverticulitis is a prevalent gastrointestinal disease that often warrants surgical intervention. However, the optimal approach between traditional laparoscopy (LC) and robotic-assisted laparoscopy (RAC) for diverticulitis remains unclear. Our research compares these techniques in patients diagnosed with left-sided diverticulitis treated at a single, tertiary referral center from 2019 to 2022. Among the 134 patients, 86 underwent laparoscopic and 48 robotic-assisted surgeries. The surgeries included in this analysis are left colectomy, sigmoid colectomy, low anterior resection, and Hartmann’s procedure. Primary outcomes were major morbidity and 30-day mortality. Secondary outcomes were operative time, conversion to open, length of stay, unplanned return to the operating room, 30-day readmission rate, and overall morbidity. While demographics and comorbidities were similar for both groups, the robotic-assisted group displayed a statistically significant longer operative time (198.0 ± 84.4 LC vs. 264.8 ± 78.5 min RAC, p < 0.001). When investigated further, there was a significant difference in operative time for uncomplicated diverticulitis cases favoring the LC approach (169.17 ± 58.1 LC vs. 244.82 ± 58.79 min RAC, p < 0.001). This significant difference, however, was not present in complicated diverticulitis cases. Other factors, such as overall and major morbidity, rate of conversion to open approach, ostomy creation, estimated blood loss, time to return of bowel function, length of stay, and 30-day readmission rate, did not significantly differ between the groups. There was no 30-day mortality in either group. Favorable patient outcomes, lack of significant difference in operative time compared with traditional laparoscopy, and absence of differences in morbidities or efficacy, raises an interesting question in the world of minimally invasive surgery: is the robotic-assisted approach emerging as the advantageous approach for complicated diverticulitis cases? We encourage additional, multi-center analysis of specifically complicated diverticulitis managed with both surgical approaches to investigate if these findings are replicated outside of our institution.
