3D Mesh-Enhanced Hiatal Hernia Repair in GERD: 3-Year Single-Center Study
Overview
This three-year single-center study evaluated 133 GERD patients with large hiatal hernias undergoing laparoscopic mesh-augmented hiatal repair using the 3D DynaMesh®-DELTA implant. The procedure demonstrated low recurrence rates and acceptable morbidity, with most patients reporting symptom improvement and satisfaction.
Background
Gastroesophageal reflux disease (GERD) is frequently associated with hiatal hernias, which increase the risk of symptom recurrence after conventional repair. Mesh augmentation of hiatal hernia repair has been shown to reduce recurrence, especially in large hernias. However, mesh implantation carries risks of complications such as migration, erosion, and fibrosis. This study investigates outcomes using a novel 3D alloplastic PVDF mesh designed for enhanced stability and visibility.

Key Findings
Laparoscopic mesh-augmented hiatal repair with DynaMesh®-DELTA was performed electively in 133 GERD patients with large hiatal hernias.
Majority (97.7%) had type III hiatal hernias, mostly exceeding 5.5 cm in diameter.
Only one patient experienced in-hospital hernia recurrence requiring redo surgery, indicating low early recurrence rates.
Mesh fixation was achieved solely with sutures without fundoplication.
Postoperative follow-up included symptom questionnaires assessing reflux, dysphagia, regurgitation, and chest pain, with most patients reporting symptom improvement and satisfaction.
No study-related exclusion criteria were applied, and the procedure was well tolerated with acceptable morbidity.
Clinical Implications
The use of the 3D DynaMesh®-DELTA for hiatal hernia repair in GERD patients appears to provide durable anatomical repair with low recurrence risk, particularly in large hernias. Its design allows for stable fixation and MRI visibility, potentially facilitating postoperative assessment. Surgeons should consider mesh augmentation in patients with large hiatal hernias to improve long-term outcomes while monitoring for mesh-related complications.
Conclusion
This study supports the safety and efficacy of laparoscopic 3D mesh-augmented hiatal hernia repair in GERD patients with large hernias, demonstrating low recurrence and favorable symptom control at three years. The novel DynaMesh®-DELTA implant represents a promising option for durable hiatal reconstruction.
