Robot-assisted hiatal hernia repair demonstrates favorable short-term outcomes compared to laparoscopic hiatal hernia repair

Background We postulated that the use of robotics may improve outcomes in hiatal hernia repair. Methods We performed a retrospective analysis of a prospectively collected Society of Thoracic Surgery database at a single institution of patients who underwent elective hiatal hernia repair from 2012 to 2017 using either laparoscopy or the da Vinci Xi robot. We compared patient characteristics and outcomes and then performed univariate and multivariate logistic regression modeling to determine the factors associated with postoperative morbidity. Results There were 293 consecutive patients who underwent elective hiatal hernia repair using either a laparoscopic ( n = 151) or a robotic ( n = 142) technique. There were no significant differences in age, gender, BMI, smoking history, presence of comorbidity, or hiatal hernia type. Seventy percent of the cases were a repair of either type III or type IV hiatal hernia. There were significantly higher ASA III and IV (7.9% vs. 4.2%, P = 0.03), higher Toupet fundoplication (83.4% vs. 44.4%, P
