Non-elective minimally invasive surgery (MIS) remains controversial, with minimal focus on robotics. This study aims to evaluate the short-term outcomes for non-elective robotic colectomies for diverticulitis. All colectomies for diverticulitis in ACS–NSQIP between 2012 and 2019 were identified by CPT and diagnosis codes. Open and elective cases were excluded. Patients with disseminated cancer, ascites, and ventilator-dependence were excluded. Procedures were grouped by approach (laparoscopic and robotic). Demographics, operative variables, and postoperative outcomes were compared between groups. Covariates with p < .1 were entered into multivariable logistic regression models for 30 day mortality, postoperative septic shock and reoperation. 6880 colectomies were evaluated (Laparoscopic = 6583, Robotic = 297). The laparoscopic group included more preoperative sepsis (31.6% vs. 10.8%), emergency cases (32.3% vs. 6.7%), and grade 3/4 wound classifications (53.3% vs. 42.8%). There was no difference in mortality, anastomotic leak, SSI, reoperation, readmission, or length of stay. The laparoscopic group had more postoperative sepsis (p = 0.001) and the robotic group showed increased bleeding (p = 0.011). In a multivariate regression model, increased age (OR = 1.083, p < 0.001), COPD (OR = 2.667, p = 0.007), dependent functional status (OR = 2.657, p = 0.021), dialysis (OR = 4.074, p = 0.016), preoperative transfusions (OR = 3.182, p = 0.019), emergency status (OR = 2.241, p = 0.010), higher ASA classification (OR = 3.170, p = 0.035), abnormal WBC (OR = 1.883, p = 0.046) were independent predictors for mortality. When controlling for confounders, robotic approach was not statistically significantly associated with septic shock or reoperation. When controlling for confounders, robotic approach was not a predictor for mortality, reoperation or septic shock. Robotic surgery is a feasible option for the acute management of diverticulitis.
