Optimal placement of self-fixating mesh in the rectus abdominis muscle for ventral hernia repair when using the enhanced-view totally extraperitoneal Rives-Stoppa technique.

Abstract

<h4>Introduction</h4>Laparoscopic retro-muscular Rives-Stoppa (RS) ventral hernia repair using the enhanced-view totally extraperitoneal (eTEP) technique (eTEP-RS) is becoming common. Although self-fixating mesh is useful with good fixation, some surgeons think the fixating surface must be oriented towards the rectus abdominis muscle for safety reasons in eTEP-RS. Attaching the self-fixating mesh to the rectus abdominis, the ceiling of the operative field, is challenging and time-consuming.<h4>Material and surgical technique</h4>First, the self-fixating mesh is folded in half with the fixation surface facing outwards. Second, we create a partition sheet and insert the sheet between the two arms of the folded mesh. The folded mesh is then inserted intracorporeally. We can unfold the mesh easily from one-quarter width to half width on the rectus abdominis muscle because of the insertion of the partition sheet. Finally, the mesh is unfolded to full width, and the mesh placement is completed.<h4>Discussion</h4>The eTEP-RS is still a new procedure and has not yet been standardized. However, our technique will increase the use of self-fixating mesh and improve the outcomes of eTEP-RS.
