With these classifications, it is possible to evaluate the surgical indications, predict how the child will respond to the procedure, as well as they allow comparative studies in different surgical centers. Objectives: The main objective of this work was a reassessment of the patients with anorectal malformations using the Krickenbeck?s classification in a hospital of reference in the south of Brazil. The aim was to compare these results with the previously used Pe?a?s classification to reevaluate the malformation cases, as well as the surgeries performed. Methods: It was performed a longitudinal, observational, descriptive, census, cohort study on the anorectal malformation cases between May 2017 and August 2017 at the Pediatric Surgery Service from the S?o Lucas Hospital from the PUCRS. The inclusion criteria was: a. all newborn children with anorectal malformations born in this hospital, b. transferred to this hospital with no previous procedure, and c. which performed a surgical procedure to correct the malformation in the first week of life in this hospital. a. Patients transferred from other hospitals with previous surgeries and b. patients which presented other malformations were excluded from the sample. A descriptive analysis of the incidence of different types of malformations and surgeries was performed and discussed. Results: Few differences were found between the classification of Pe?a and the classification of Krickenbeck. We found mainly cases of perineal, vestibular, retourethral, rectovaginal and cloaca fistula treated by means of colostomy surgeries and posterior sagittal anorectoplasty. Conclusions: The present study points out that there few differences between the Pe?a and Krickenbeck classifications. We suggest the use of a classification applied and based on the occurrence of cases of anorectal malformations in this service, containing the main relevant information of both classifications above. / Introdu??o: As classifica??es das malforma??es anorretais surgiram com o objetivo de melhor classificar cada malforma??o e com isso possibilitar a escolha da melhor abordagem cir?rgica. Atrav?s desses modelos ? poss?vel avaliar as indica??es cir?rgicas, tentar prever como a crian?a responder? ao procedimento e permitir que estudos sejam comparados em diferentes centros cir?rgicos. Objetivos: Reavaliar os pacientes com malforma??es anorretais pela classifica??o de Krickenbeck em Hospital de refer?ncia para esse tipo de anomalia no sul do Brasil. Comparar com a classifica??o previamente usada de Pe?a para avaliar as malforma??es e cirurgias realizadas. M?todos: Estudo de coorte, longitudinal, observacional, descritivo, de censo, foi realizado entre maio de 2017 e julho de 2017 no Servi?o de Cirurgia Pedi?trica do Hospital S?o Lucas da PUCRS. Os crit?rios de inclus?o foram: a. todas as crian?as rec?m-nascidas com malforma??es anorretais nascidas neste servi?o ou b. transferidas para o mesmo sem nenhum procedimento pr?vio; c. terem realizado procedimento cir?rgico para corre??o da malforma??o na primeira semana de vida neste servi?o. Foram exclu?dos a. os pacientes transferidos de outros hospitais com cirurgias pr?vias e b. os pacientes que apresentavam outras malforma??es com indica??es cir?rgicas. Foi realizada uma an?lise descritiva das incid?ncias dos diferentes tipos de malforma??o. Resultados: Encontraram-se poucas diferen?as entre a classifica??o de Pe?a e a classifica??o de Krickenbeck. Foram encontrados principalmente casos de f?stula perineal, vestibular, retouretral, retovaginal e cloaca tratados mojoritariamente atrav?s de cir?rgias de colostomia e anorretoplastia sagital posterior. Conclus?es: A presente pesquisa aponta que praticamente n?o h? diferen?as entre as classifica??es de Pe?a e Krickenbeck. Sugere-se a utiliza??o de uma classifica??o aplicada e baseada na ocorr?ncia dos casos de malforma??es anorretais neste servi?o, contendo as principais informa??es relevantes de ambas as classifica??es acima.
