BN SO28 - Dual Mesh Technique in Revisional Complex Laparoscopic Repair of Recurrent Paraesophageal Hernia (PEH)

Abstract Background Mesh Augmentation in laparoscopic repair of complex PEH has been an ongoing debate with regards to its risk profile and success rate in reducing hernia recurrence.1 There have been concerns regarding the deployment of non-absorbable mesh around the hiatus resulting in erosion and stricture, which may lead to oesophagectomy or gastrectomy.2 Absorbable mesh has been introduced with appealing advantages of lower mesh-related morbidities, however its high cost and unclear long-term durability remains questionable for its role as an ideal mesh.2 Method This is the case of a 65-year-old patient with chronic reflux symptoms undergoing revisional complex laparoscopic repair of recurrent type 4 PEH. The focus of this video is using a dual mesh technique involving fixation of a non-absorbable synthetic mesh at least 15mm from the oesophageal wall, reinforced with placement of an absorbable biosynthetic mesh which is in contact with the hiatus boundary. Results With regards to position of the permanent synthetic mesh, direct contact with the oesophagogastric wall should be avoided due to complications secondary to erosions and strictures. The deployment of a second mesh of absorbable material is preferred in this patient for hiatal reinforcement to reduce risk of recurrence due to friability of adjacent tissues. Conclusion The dual mesh technique aims to overcome the limitations of both types of mesh materials while preserving their individual benefits, expectantly reducing recurrence.
