Abstract
The number of robotic hiatal hernia repairs (RHHR) is increasing. However, the superiority of this minimally invasive approach remains controversial. The aim of this study was to evaluate the available literature reporting on outcomes of RHHR compared with laparoscopic hiatal hernia repair (LHHR) in adult patients. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Web of Science, PubMed, the Cochrane Library, and ClinicalTrials.gov databases were searched. Identified publications were reviewed independently by two authors. High heterogeneity was further explored through sensitivity analysis. The primary endpoint was the development of postoperative complications. Secondary endpoints included operation time, intraoperative complications, 30 day readmission rates and length of stay. The analysis was performed using Stata 17.0 software. A total of 7 studies totaling 10078 patients met the inclusion criteria. Five studies included postoperative complications. The postoperative complications rate was 4.25% (302/7111) in the LHHR group, and 3.49% (38/1088) in the RHHR group. Postoperative complications significantly decreased after RHHR compared with LHHR (OR 0.52; 95% CI 0.36 to 0.75, P = 0.000). Three studies involving 2176 patients reported length of hospital stay. In the three studies, the mean Length of hospital stay was 3.2 days in the RHHR group, and 4.2 days in the LHHR group. Length of hospital stay was decreased by a mean of 0.68 days for RHHR compared with LHHR (WMD, − 0.68 days; 95% CI − 1.32 to − 0.03, P = 0.02). There was no significant difference between the RHHR group and the LHHR group regarding operative time, intraoperative complications, and 30 day readmission (P > 0.05). Our research shows that RHHR may be the better option, as the approach decreases postoperative complications and length of hospital stay.
