Reducing recurrence rates in hiatal hernia repair: Results of a quality improvement study.

Abstract

Background: Patient and procedure factors are considered in the decision-making process for surgical repair of hiatal hernias. Recurrence is multi-factorial and has been shown to be related to size, type, BMI and age.

Aims: This study examined recurrence rates in a single institution, identified areas for improved surgical technique, and re-assessed recurrence following implantation of a quality improvement initiative.

Methods: A retrospective review of patients undergoing hiatal hernia repair surgery between 2018 and 2022 was conducted. Demographics, pre-operative characteristics, intra-operative procedures and recurrence rates were reviewed.

Results: Seventy-five patients from 2018 to 2020 and 34 patients from 2021 to 2022 were identified. The recurrence rate was 21% in 2018-2020, with 14% requiring a revisional procedure. Recurrence and re-operation were subsequently reduced to 6% in 2021 and 2022, which was statistically significant (p = 0.043). There was an increase in gastropexy from 21% to 41% following the review (p = 0.032), which was mainly reserved for large and giant hernias. Procedural and literature review, alongside gastropexy, can be attributed to recurrence rate reduction.

Conclusions: It is important to educate patients on the likelihood and risk factors of recurrence. A comprehensive review of procedures and a quality improvement program in our facility for hiatal hernia repair is shown to reduce recurrence.
