Laparoscopic repair of lumbar hernias.

BACKGROUND

Lumbar hernias are rare defects in the posterolateral abdominal wall that may be congenital or acquired. Repairing these defects is difficult by virtue of their location and the inherent weakness of the surrounding tissues. We report a series of seven patients who had their lumbar hernias repaired laparoscopically at two institutions.

STUDY DESIGN

We retrospectively reviewed all lumbar hernias repaired laparoscopically in our institutions within the last 16 months (August 1996 to November 1997). Postoperative followup was 1-15 months.

RESULTS

Seven patients underwent laparoscopic repair. Five hernias were acquired defects and two were congenital. One to three defects were found per patient. The average size of the hernia defect was 77.8 cm2. We used a polypropylene or a polytetrafluoroethylene mesh in all patients; the average size of the mesh used was 336.4 cm2. The average length of hospital stay was 1.7 days. One patient returned with an abscess over the mesh, which necessitated removal of the graft. Otherwise, there were no complications, and the remaining six patients had no recurrences after followup of 1-14 months.

CONCLUSIONS

The laparoscopic approach is safe and effective for repairing lumbar hernias. Advantages of this approach include excellent operative visualization, decreased hospital stay postoperatively, and a solid repair without recurrence during shortterm followup.
