The Enhanced-View Totally Extraperitoneal Repair for Ventral and Incisional Hernia: Midterm Results of an Evolving Technique.

Introduction: In the field of abdominal wall hernias, several innovative procedures have been developed, including the extended/enhanced-view totally extraperitoneal (eTEP) hernia repair technique. Initially introduced for laparoscopic hernia repair by J. Daes, it was subsequently applied to ventral hernia repair (VHR) and incisional hernia repair (IVHR) by I. Belyansky et al. This article presents the midterm experience and outcomes of our center's experience with the endoscopic technique based on the principles of eTEP during IVHR and VHR. Method: A review was conducted of a prospectively collected database of abdominal wall hernia. Patients who underwent eTEP VHR or IVHR between October 2018 and February 2021 were identified. Results: A total of 51 patients underwent an eTEP-RS or eTEP-TAR procedure, with a 24-month follow-up period. Of the 51 patients included in the study, 43 underwent eTEP-RS treatment, while 8 required an additional transversus abdominis release (3 unilaterally). One patient developed a large hematoma necessitating reoperation and drainage via the eTEP approach. Seven patients developed seromas, which were treated conservatively, while 2 patients experienced surgical site infections, which were managed with a single-use negative pressure wound therapy system. Two patients exhibited recurrence at sites above the epigastric edge of the mesh. Conclusion: Moreover, the advancement of minimally invasive surgical techniques for abdominal wall reconstruction has rendered the eTEP approach a viable option for both primary and incisional VHR, with promising midterm outcomes.
