381. 15-YEAR OUTCOMES FOLLOWING GIANT HIATUS HERNIA REPAIR

Résumé fourni par la source

Abstract Background Laparoscopic repair of large hiatus hernias provides excellent clinical outcomes in symptomatic patients. However, recurrence is common and long-term follow-up (>10 years) is limited to small sample sizes. The aim of this study is to evaluate long-term clinical outcomes following repair. Methods Patients who underwent surgical repair of a very large hiatus hernia (> 50% intrathoracic stomach) with a minimum of 10-year follow-up were identified from a prospectively collected database. A standardised questionnaire was sent to patients to identify presence and severity of symptoms, as well as overall satisfaction. Results were compared to preoperative and short-term (<12 months) outcomes. Results Between 2000–2015, 321 suitable patients underwent large hiatus repair with a minimum 10-year follow-up were identified. 137 patients (42.7%) completed and returned the questionnaire. Follow-up ranged from 10 to 24.1 (mean 15.2) years. There was a significant improvement in heartburn (5.62 vs 2.08, p < 0.001) and regurgitation (6.77 vs 2.04, p < 0.001) severity comparing preoperative to long-term follow-up results. 90 patients (65.7%) reported ongoing use of antacid medications. Other commonly reported symptoms include: dysphagia (41.6%), increased flatulence (51.8%), bloating (34.3%) and early satiety (30.7%). 110 patients (80.9%) report no ongoing to mild symptoms. Overall satisfaction was 8.15/10. Conclusion Despite high rates of recurrence in the literature, we found laparoscopic repair of large hiatus hernia provides both an effective and sustained improvement in symptoms.
