[Morpho-functional evaluation of subjects who had undergone surgery for ano-rectal malformations using the Peña technique]

The approach to patients with Ano-Rectal Malformations (ARM) has undergone a substantial change in these last years due to the evolution of the studies of the anatomy and physiology carried out by Peña and de Vries. The authors report their experience on 15 patients and analyse the clinical and instrumental results according to the quality of life of the patients. There are different clinical criteria for the postoperative evaluation of these patients. The authors considered the Kelly, Kiesewetter, Peña and Holdschneider methods and compared the different values obtained. Moreover, they analysed the results of anorectal manometry performed in 10 patients and their correlations with clinical scores. The authors assert that the TC or NMR tests are unnecessary for these patients, since these methods demonstrate a correct position of the rectum within the muscular structure, but do not allow a correct evaluation of the quality of life of these patients. The clinical results obtained by the authors are satisfying; however, the number of patients is limited and the follow-up is relatively short.
