Background
Patients requiring concurrent paraesophageal hernia repair (CPHR) have been shown to have favorable outcomes in primary bariatric surgery. However, patients requiring revisional or conversional surgery represent a group of patients with higher perioperative risk. Currently, few reports on concurrent paraesophageal hernia repair utilizing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database are available. The primary aim of this study was to determine perioperative complications associated with CPHR and the Roux-en-Y gastric bypass (RYGB) as a revisional/conversional operation.
Methods
In this study, patients undergoing revisional/conversional RYGB between 2015 and 2020 were accessed via the MBSAQIP database. Patients were categorized based on the presence of a paraesophageal hernia as a concurrent procedure. Patients who underwent revisional/conversional surgery without additional procedures were utilized for controls. A propensity score-matched cohort was generated and E-analysis utilized to assess unmeasured confounding.
Results
After exclusions, 35,698 patients were available. Patients receiving CPHR were more likely to be female (90.79% vs 87.37%; p < 0.001) and have increased frequency of gastroesophageal reflux disease (69.20% vs 51.69%; p < 0.001). However, these patients had lower frequencies of sleep apnea (24.12% vs 30.13%; p < 0.001), hypertension requiring medication (38.51% vs 42.59%; p < 0.001), and decreased frequency of hyperlipidemia (19.44% vs 21.60%;p < 0.001). After matching, 6,231 patient pairs were developed and showed that patients undergoing CPHR were at increased risk of readmission (9.44% vs 7.58%; p < 0.001), intervention (3.56% vs 2.79%; p = 0.018), increased requirement for outpatient dehydration treatment (5.87% vs 4.67%;p = 0.004), and overall increased operation time (169.3 min ± 76.0 vs 153.5 ± 73.3; p < 0.001). However, there were no significant increases in the rates of reoperation, death, postoperative leak complications, or bleeding complications after CPHR.
Conclusion
Patients undergoing revisional/conversional RYGB with CPHR may be at higher risk for a small number of rare postoperative complications. CPHR is a safe procedure in patients undergoing revisional/conversional RYGB in the short-term postoperative period.
