Aim The recurrence rate of hiatus hernia (HH) is high after laparascopic surgery (25–42%). HH repair can be reinforced by means of additional ventral sutures, pledgets or mesh placement. We determined the recurrence rate of HH after surgery and established whether lower long-term recurrence rates can be achieved with reinforcement techniques. Methods Patients were included in this retrospective cohort study if they underwent a laparoscopic fundoplication in our hospital between 2012–2019. HH was measured on CT scans and patient files were reviewed. Results In total, 307 patients were included, 206 women and 101 men. Pre-operatively, 102 patients were diagnosed with type III HH and 68 patients with type IV HH. The median transverse diameter of the HH was 3.2 cm. 208 patients underwent a Toupet fundoplication and 97 patients underwent a Nissen fundoplication. Reinforcements consisted of ventral sutures in 132 patients, pledgets in 89 patients and mesh in 17 patients. After primary surgery, recurrence of HH was diagnostically confirmed in 64 patients (20.8%). Secondary surgery was performed in 54 patients (17.6%) and tertiary surgery in 5 patients (1.6%). Use of pledgets during primary surgery (OR=0.34, p=0.048) was significantly associated with fewer recurrences, corrected for confounding factors. Use of ventral sutures and mesh were not significantly associated with reduced recurrence rates. Conclusions The recurrence rate among HH patients in our hospital was 20.8% with a mean follow-up time of 6 years. In future, the use of pledgets might lead to fewer recurrences after primary laparoscopic repair of HH.
