[Ventral Hernia Repair in Endoscopically Total Extrapertoneal Technique (eTEP) - Evaluation of Postoperative Outcome and One Year Follow-up].

BACKGROUND:Several recent meta-analyses have identified the retromuscular plane as the preferred mesh position in ventral hernia repair. Open surgery used to be the standard technique for these procedures. However, new minimally invasive techniques with totally extraperitoneal access and mesh positioning in the retromuscular plane have evolved. METHODS:Between September 2018 and March 2019, 18 consecutive patients with ventral hernia were treated endoscopically in the totally extraperitoneal technique. Depending on the localisation and size of the hernia, the appropriate access was chosen and an uncoated mesh was placed in the retromuscular space in all patients. Data of patients' characteristics as well as peri- and postoperative parameters were collected. One year after surgery, patients were asked about recurrence, pain and complications, using the questionnaire of the herniamed data base. RESULTS:No intraoperative complications were noted. Postoperatively, there was one retromuscular seroma that did not need treatment, one temporary paralysis of the radial nerve and one pulmonary embolism. None of these complications led to persistent problems. 17 of 18 patients were available for follow-up. One year follow-up showed no hernia recurrence. One patient had pain at rest requiring treatment. CONCLUSIONS:Totally extraperitoneal endoscopic hernia surgery is a safe and promising new technique that is also feasible in complex hernias and with satisfactory 1 year results. This technique can combine the advantages of minimally invasive surgery with those of extraperitoneal mesh placement.
