Abstract
The lumbar region has two sites of reduced abdominal wall resistance, the superior lumbar triangle and the inferior lumbar triangle. An abdominal hernia that occurs at these sites is referred to as a lumbar hernia. A case of lumbar hernia occurring after iliac crest bone harvest for which laparoscopic hernia repair was performed is reported. The patient was a 74-year-old man who, at the age of 67 years, underwent vertebroplasty for a compression fracture of the cervical spine, during which bone was harvested from the right iliac crest. He first visited our department due to a protrusion in the right lumbar region that he noticed two years earlier. The patient was diagnosed with a lumbar hernia occurring after iliac crest bone harvest in which the hernia contents were the ascending colon. Surgery was performed using three ports with the patient in the left lateral decubitus position. The ileocecum was mobilized, a 4.2-cm hernial orifice was identified, a Bard Composix Mesh® shaped into a circle with a 10-cm diameter was placed to secure a 3-cm overlap, and the entire periphery was fixated using AbsorbaTackTM. Fixation of the ileocecum to the abdominal wall was performed using a few tacks, and the procedure was concluded with a favorable visual field and operability. The patient was discharged on day 6 following an uneventful postoperative course and is currently, seven months postoperatively, being followed up with no recurrence.
