[Problems of reoperation after prosthetic repair of groin hernia].

The easy performance and the efficiency of these repairs should make the surgeon attentive to some related drawbacks, which can scarcely appear when reoperating on the bladder or the prostate, also on the iliac vessels. The encountered difficulties are related to the scar sclerosis much or less extensive and/or effective, invading the Retzius and/or the Bogros' spaces. The authors report their intraoperative and anatomical findings. They propose the following solutions: (1) when the cleavage of the Retzius' space is impossible (for bladder or prostate surgery): a subperiosteal retropubic cleavage, either isolated or combined with a transperitoneal approach. (2) When the cleavage of the Bogros' space is impossible (for a surgery on the iliac vessels): a transperitoneal approach; but the prevention of the perivascular sclerosis after the use of large prostheses relies on the easy preservation of the funicular sheath, able to protect the iliac vessels, providing no slit has been done on the mesh prosthesis.
