Dynamic MR defecography is equivalent to X-ray defecography for the diagnosis of abnormalities of the posterior compartment of the pelvic floor.

Preputial tumours in ferrets are frequently malignant and therefore warrant prompt investigation. As many cases do not respond favourably to surgery, even in combination with radiation therapy, wide surgical resection has been recommended. Such a procedure may necessitate partial or total penile resection but outcomes have thus far not been well described. The current case series describes two ferrets in which surgical resection, including penile amputation, was performed using 10 and 5 mm margins, respectively. In the first case, no recurrence of preputial gland adenocarcinoma was noted for 32 months postsurgery, whereas multiple attempts at surgery and radiation therapy were unsuccessful in the second. These cases suggest that margins of at least 1 cm may help achieve a better outcome. Penile amputation for the treatment of preputial tumours appears to be well tolerated by ferrets, as demonstrated by these cases.

L'utilisation des prothèses synthétiques dans la chirurgie de la statique pelvienne est en plein essor. Pour les chirurgiens, l'inquiétude majeure concerne les complications secondaires à l'utilisation de ces matériaux. La compression rectale, encore jamais décrite dans la littérature, en fait partie. Nous rapportons trois cas de compressions rectales après mise en place d'une prothèse prérectale par voie vaginale. Des symptômes anorectaux étaient présents à 9,7 ± 4 mois (5-12) postopératoires. Le diagnostic étiolo-gique a été retardé à 21 ± 12 mois (9-33). Le toucher rectal est essentiel au diagnostic. L'échographie périnéale, la défécographie ou l'IRM dynamique complètent les données cliniques. La décompression chirurgicale est toujours efficace. La compression rectale peut être une complication des cures de prolapsus par prothèse prérectale type Transvaginal Mesh qu'il faut savoir diagnostiquer, traiter et prévenir.

Mots clés Prolapsus génital · Transvaginal Mesh · Compression rectaleAbstract The employment of synthetic implants in the surgery of pelvic stasis is expanding rapidly. For surgeons, the main anxiety is that of complications resulting from the use of these materials. Rectal compression is one of these, though it has not yet been described in the literature. We report three cases of rectal compression after positioning a pre-rectal implant via a vaginal approach. Anorectal symptoms were present at 9.7 ± 4 months (5-12) postsurgery. Diagnosis was delayed by 21 ± 12 months (9-33). Rectal examination is essential to make the diagnosis. Perineal ultrasound, defecography, and dynamic MRI provide further information. Surgical decompression is always effective. Rectal compression can complicate treatment of prolapse using pre-rectal transvaginal mesh types of implant. It is necessary to know how to diagnose this, and how to treat and prevent it. To cite this journal: Pelvi-Périnéologie 5 (2010).
