Background:

The study aims to evaluate the postoperative outcomes of hiatal hernia repair with cruroplasty alone compared to the addition of fundoplication. We theorize that previously reported inferiority with crural-only repairs resulted from a lack of real-time feedback regarding the effectiveness of the repair. EndoFLIP TM allows for intraoperative assessment of the gastroesophageal junction. We predict equivalent postoperative outcomes will be achieved between hiatal hernia repairs performed by cruroplasty alone and with fundoplication when the final distensibility index (DI) is similar.

Methods:

This retrospective cohort review includes patients who underwent hiatal hernia repair with intraoperative EndoFLIP TM between 2020 and 2022. Propensity score-matching was utilized to identify cruroplasty alone and fundoplication patients with a final DI within 0.5 mm 2 /mmHg of one another. Postoperative development of dysphagia, reflux, or hernia recurrence were primary outcomes of interest.

Results:

Forty-two patients were included in the analysis. While the cruroplasty-alone cohort had an increased age at the time of surgery, 50% more redo repairs, and a slightly higher BMI, there were no significant preoperative or intraoperative differences between groups. Overall, the median duration of follow-up was 111 (IQR 213) days. During that time, there were no differences in the development of postoperative reflux or dysphagia between cohorts ( P  = .228 and P  = .451, respectively). Kaplan-Meier curve analysis did not demonstrate a significant difference in time-to-event for either outcome. There were 3 radiographic recurrences, with 2 occurring after fundoplication ( P  = .000).

Conclusions:

This is the first study to utilize intraoperative EndoFLIP TM to determine the need for fundoplication during hiatal hernia repair. The results demonstrate no additional short-term benefit from fundoplication performance. These findings argue against routine fundoplication when an acceptable DI can be achieved after cruroplasty. Further research is needed to validate these results.
