Laparoscopic total extraperitoneal superior and inferior lumbar hernias repair without traumatic fixation: Two case reports

Abstract

BACKGROUND: The lumbar area is limited by the bone structures (superiorly by the 12th rib and inferiorly by the iliac crest); furthermore, several important nerves, including the genitofemoral nerve, lateral femoral cutaneous nerve, and ilioinguinal and iliohypogastric nerves, are all exposed in this area after retroperitoneal dissection during lumbar hernia repair, which render the risk and challenge for lumbar hernia repair and mesh fixation. In addition, the superior and inferior lumbar hernias, although had the same name of lumbar hernia, are quite different according to the anatomical location, and there is no standard and preferred method for lumbar hernia repair. In the present study, we present our techniques of total extraperitoneal (TEP) superior and inferior lumbar hernia repair. METHODS: The TEP approaches were performed in the superior and inferior lumbar hernias. Due to the different anatomic locations of the superior and inferior lumbar hernias, the trocar sites were also different. In the present procedure, with the use of self-gripping mesh, the traumatic fixation was avoided. RESULTS: After TEP lumbar hernia repair, both patients had minimal postoperative pain and were discharged 1 day and 3 days after operation without complications, respectively. CONCLUSION: Different pathways and trocar arrangement are necessary according to the different locations of superior and inferior lumbar hernias. The use of self-gripping mesh in the retroperitoneal space avoids the traumatic fixation, and TEP could be a promising technique for primary lumbar hernia repair.
