Outcomes after robotic-assisted inguinal hernia repair were similar to outcomes after laparoscopic or open repair. Longer operative duration during robotic repair may contribute to higher rates of skin and soft tissue infection. Higher cost should be considered, along with surgeon comfort level and patient preference when deciding whether inguinal hernia repair is approached robotically.

Background: As robotic surgery becomes more ubiquitous, determining clinical benefit is necessary in order to justify the cost and time investment required to become proficient. We hypothesized that robotic cholecystectomy would be associated with improved clinical outcomes but also increased cost as compared with standard laparoscopic cholecystectomy. Materials and methods:All patients undergoing robotic or laparoscopic cholecystectomy at a single academic hospital between 2007-2017 were identified using an institutional clinical data repository. Patients were stratified by operative approach (robotic vs. laparoscopic) for comparison and propensity score-matched 1:10 based on relevant comorbidities and demographics. Categorical variables were analyzed by Chi-square test and continuous variables using Mann-Whitney U test.Results: 3,255 patients underwent cholecystectomy during the study period. There were no differences in demographics or BMI, but greater rates of diabetes mellitus, hypertension, and gastroesophageal reflux disease were present in the laparoscopic group. After matching (n=106 robotic, n=1060 laparoscopic), there were no differences in preoperative comorbidities. Patients who underwent robotic cholecystectomy had lesser durations of stay (Robot: 0.1±0.7 vs. Lap: 0.8±1.9, p < 0.0001) and lesser 90-day readmission rates (Robot: 0% [0], Lap: 4.1% [43], p = c
