BackgroundNearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications. Furthermore, the optimal technique for redo-ARS remains debatable. The purpose of the current multicenter study was to review the outcomes of redo-fundoplication and to identify the best ARS repair technique for recurrent HH and gastroesophageal reflux disease (GERD).MethodsData on 975 consecutive patients undergoing hiatal hernia and GERD repair were retrospectively collected in five European high-volume centers. Patient data included demographics, BMI, techniques of the first and redo surgeries (mesh/type of ARS), perioperative morbidity, perioperative complications, duration of hospitalization, time to recurrence, and follow-up. We analyzed the independent risk factors associated with recurrent symptoms and complications during the last ARS. Statistical analysis was performed using GraphPad Prism® and R software®.ResultsSeventy-three (7.49%) patients underwent redo-ARS during the last decade; 71 (98%) of the surgeries were performed using a minimally invasive approach. Forty-two (57.5%) had conversion from Nissen to Toupet. In 17 (23.3%) patients, the initial Nissen fundoplication was conserved. The initial Toupet fundoplication was conserved in 9 (12.3%) patients, and 5 (6.9%) had conversion of Toupet to Nissen. Out of the 73 patients, 10 (13%) underwent more than one redo-ARS. At 8.5 (1-107) months of follow-up, patients who underwent reoperation with Toupet ARS were less symptomatic during the postoperative period compared to those who underwent Nissen fundoplication (p = 0.005, OR 0.038). Patients undergoing mesh repair during the redo-fundoplication (21%) were less symptomatic during the postoperative period (p = 0.020, OR 0.010). The overall rate of complications (Clavien-Dindo classification) after redo surgery was 11%. Multivariate analysis showed that the open approach (p = 0.036, OR 1.721), drain placement (p = 0.0388, OR 9.308), recurrence of dysphagia (p = 0.049, OR 8.411), and patient age (p = 0.0619, OR 1.111) were independent risk factors for complications during the last ARS.ConclusionsFailure of ARS rarely occurs in the hands of experienced surgeons. Redo-ARS is feasible using a minimally invasive approach. According to our study, in terms of recurrence of symptoms, Toupet fundoplication is a superior ARS technique compared to Nissen for redo-fundoplication. Therefore, Toupet fundoplication should be considered in redo interventions for patients who initially underwent ARS with Nissen fundoplication. Furthermore, mesh repair in reoperations has a positive impact on reducing the recurrence of symptoms postoperatively.
