Complications Following Robotic Hiatal Hernia Repair Are Higher Compared to Laparoscopy

The use of robotic platforms in surgery is becoming increasingly common in both practice and residency training. In this study, we compared the perioperative outcomes between robotic platforms and traditional laparoscopy in paraesophageal hernia repair.

A retrospective population-based analysis was performed using the National Inpatient Sample for the period of 2010-2015. Adult patients (≥18 years old) who underwent laparoscopic or robotic paraesophageal hernia repairs were included. Weighted multivariable random intercept linear and logistic regression models were used to assess the effects of robotic surgery on patient outcomes.

A total of 168,329 patients were included in the study. The overall adjusted rate of complications was significantly higher in patients who underwent robotic paraesophageal hernia (PEH) repair compared to laparoscopic PEH OR (95% CI) = 1.17 (1.07, 1.27). Specifically, respiratory failure OR (95% CI) = 1.68 (1.37, 2.05) and esophageal perforation OR (95% CI) = 2.19 (1.42, 3.93) were higher in robotic PEH patients. A subset analysis was performed looking at high-volume centers (>20 operations per year), and, although the risk of complications was lower in the high volume centers compared to intermediate volume centers, complication rates were still significantly higher in the robotic surgery group compared to laparoscopic. Overall charges per surgery were significantly higher in the robotic group.

Robotic PEH repair is associated with significantly more complications compared to laparoscopic paraesophageal hernia repair even in high-volume centers.
