Precostal top-down extended totally extraperitoneal ventral hernia plasty (eTEP): simplification of a complex technical approach.

Retromuscular mesh augmentation is generally considered to be the ideal technique for repairing ventral hernias and can be performed laparoscopically by 'enhanced view totally extraperitoneal plasty' (eTEP)-a technically complex procedure that requires a high level of surgical expertise. We aimed to develop a simplified technical modification. Thirty-one patients with ventral hernias were operated with a modified precostal, top-down eTEP approach, and prospectively recorded in our hernia registry. We describe this novel standardized precostal access and the bilateral development of both retromuscular compartments with a cylindrical dilating balloon port. Demographic-, hernia-specific-, and perioperative data were analyzed retrospectively. Twenty-two primary and 9 incisional hernias with an average defect size of 34.5 cm With technical modification of precostal access and pneumatic balloon dilation of both retro-rectus compartments, the complex procedure can be simplified through time saving and straightforward unidirectional 'top-down' dissection. The better overview facilitates the crossover for connecting both retro-rectus spaces. In addition, the cranial access allows the anterior- and posterior layers to be closed up to the xiphoid.
