Spigelian hernias: a new repair technique using preshaped polypropylene umbrella plugs.

The spigelian hernia is a rare kind of abdominal wall defect that has been treated using a variety of techniques. Recently, we encountered 6 patients with spigelian hernias in whom we have used a new modality consisting of the tension-free occlusion of the hernia ring with a preshaped polypropylene umbrella-type plug. The follow-up was more than 1 year without evidence of recurrence. This technique simplifies the repair and has the advantage of producing minimal postoperative pain and disability.
