[Recurrent hernia of the Jean Louis Petit triangle: a case study]. / Récidive d'une hernie primaire de Jean-Louis Petit: à propos d'un cas.

Hernia of the Jean Louis Petit triangle and hernia of Grynfeltt's quadrilateral space can be classified as lumbar hernias. Its clinical diagnosis is confirmed by computed tomography and, possibly, by ultrasound or x-ray. There is a formal indication for surgery including swelling or functional discomfort but, above all, the risk of strangulation. We here report a rare case of recurrence of primary hernia of the Jean Louis Petit triangle in a 65-year old man.
