Full textAnismus is one of the most frequent disease in carrying patients of obstructed defecation and it is being present in about 50.0% of the constipated patients. The aim of this study is to demonstrate the use of the bi-dimensional anorectal ultrasound (2-D USD) for the diagnosis of anismus and comparing the results with the anus manometry and the three-dimensional anorectal ultrasound (3-D USD). Sixty adult women with obstructed defecation symptoms were evaluated in this prospective and comparative study, coming from Colorectal Unit of the Hospital UniversitÃrio Walter CantÃdio of the Universidade Federal do CearÃ, between September 2006 to March 2007. All the patients were initially submitted to anus manometry (BAD) and then divided in two groups with 30 patients each. Group I was formed by patients without anismus at the mean age of 48,63 (24 the 69) years, while group II with carrying patients with anismus at the mean age of 51,20 (27 the 78) years. After that, patients of both groups were submitted to the 3-D and 2-D USD by an examiner who was unaware of the results of the manometries. The average size of the gotten angle with the 3-D USD at rest position of group I was 87.28Â Â 0.80Â (76,5Â-96,2Â) and of 87.87Â Â 0.99Â (78,5Â-109,4Â) in group II. (p=0,3220). The average size of the angle during the evacuatory effort of group I was of 93.25Â Â 1.49Â (74,9Â-106,9Â) and of 85.27Â Â 1.35Â (72,0Â- 101,8Â) in group II, (p=0.007). The average size of the gotten angle with the USD 2-D at rest positions of group I was 62.61Â Â 1.15Â (50,9Â-75,0Â) and of 65.51Â Â 0.89Â (50,8Â-73,0Â) in group II (p=0,0257). The average size of the angle during the evacuating effort of group I was of 59.75Â Â 1.42Â (44,0Â-73,0Â) and of 69.40Â Â 1.06Â (52,6Â-79,5Â) in group II, (p< 0,001). Comparing the differences of the angles size at rest position and during evacuatory effort of the patients of group I with group II, using 2-D and 3-D USD, there was statistically significant difference (p< 0,0001). Comparing the results between the 2-D USD with the manometry, there was agreement in 86,67% and 83,33% of the patients of group I and group II respectivelly. Comparing the results between the 2-D and 3-D USD, there was agreement of 93,33% in the evaluation of the patients of group I and of 90,0% of the patients of group II. The agreement among the three methods was 86,67% as positive predictive value and 83.33% as negative predictive value. It is concluded that the use the 2-D USD was considered efficient in the diagnosis of anismus by the high indication of agreement among the three used methods
Anismus à uma das afecÃÃes mais freqÃentes em pacientes portadores de evacuaÃÃo obstruÃda, estando presente em cerca de 50.0% dos pacientes constipados. O objetivo deste trabalho à avaliar se o USD 2-D faz o diagnÃstico de anismus, quando comparado a manometria anal e ao USD 3-D. Foram avaliadas neste estudo prospectivo e comparativo 60 mulheres adultas com sintomas de evacuaÃÃo obstruÃda, provenientes do ServiÃo de Coloproctologia do Hospital UniversitÃrio Walter CantÃdio da Universidade Federal do CearÃ, no perÃodo entre setembro de 2006 a marÃo de 2007. Todas as pacientes foram inicialmente submetidas à manometria anal (MA) e, distribuidas em dois grupos com 30 pacientes cada. O grupo I foi constituÃdo por pacientes sem anismus e com mÃdia de idade 48,63 (24 a 69) anos, enquanto o grupo II com pacientes portadoras de anismus e com mÃdia de idade 51,20 (27 a 78) anos. Em seguida, as pacientes de ambos os grupos foram submetidas à USD 3-D E 2-D por um examinador que desconhecia o resultado da manometria. O tamanho mÃdio do Ãngulo obtido com o USD 3-D no repouso do grupo I foi 87.28  0.80 (76,5Â-96,2Â) e de 87.87  0.99 (78,5Â-109,4Â) no grupo II. (p=0,3220). O tamanho mÃdio do Ãngulo no esforÃo evacuatÃrio do grupo I foi de 93.25  1.49Â(74,9Â-106,9Â) e de 85.27  1.35Â(72,0Â-101,8Â) no grupo II, (p=0.007). O tamanho mÃdio do Ãngulo obtido com a USD 2-D no repouso do grupo I foi 62.61  1.15Â(50,9Â-75,0Â) e de 65.51  0.89Â(50,8Â-73,0Â) no grupo II (p=0,0257). O tamanho mÃdio do Ãngulo no esforÃo evacuatÃrio do grupo I foi de 59.75  1.42Â(44,0Â-73,0Â) e de 69.40  1.06Â(52,6Â-79,5Â) no grupo II, (p<0.001). Comparando a diferenÃa do tamanho dos Ãngulos no repouso e no esforÃo evacuatÃrio dos pacientes do grupo I com o grupo II, ao USD 2-D e 3-D, foi observado diferenÃa estatisticamente significante (p< 0,0001). Comparando os resultados obtidos ao USD 2-D com a manometria, houve concordÃncia em 86,67% das pacientes de ambos os grupos. Comparando os resultados obtidos entre o USD 2-D com o 3-D, houve concordÃncia de 93,33% na avaliaÃÃo das pacientes do grupo I e de 90,0% das pacientes do grupo II.A concordÃncia entre os trÃs mÃtodos foi de 86,67% como valor preditivo positivo e 83,33% como valor preditivo negativo. Conclui-se que a o USD 2-D foi eficaz em averiguar o diagnÃstico do anismus pelo elevado Ãndice de concordÃncia entre os trÃs mÃtodos utilizados

Full textLe mouvement de la prostate est un problème critique dans le traitement conforme du cancer de la prostate, le plus commun cancer parmi les hommes au Canada. La radiothérapie guidée par l'image (IGRT) utilisant les images ultrasons (US) quotidiennes est une technique largement utilisée pour régler ce problème. Une nouvelle technique de localisation ultrasons en trois dimensions, basée sur une méthode de vérification intra modalités, a été testée à l'Hôpital General de Montreal en 2005. L'objectif principal de cette thèse a été de mieux quantifier l'amplitude du mouvement de la prostate à travers une analyse rétrospective de 32 patients et d'évaluer son impacte dans la dosimétrie des traitements de la prostate avec et sans localisation US. L'analyse rétrospective a montré que la moyenne écart-type des mouvements de la prostate dans les directions AP, SI et DG est de -3.3 7.9 mm, -1.1 6.4 mm et -0.2 5.6 mm, respectivement. La plus grande rotation survient autour de l'axe latérale, avec une moyenne écart-type de -0.9 4.6, s'échelonnant entre -6.7 et 8.0. Pour estimer l'impacte dosimétrique du mouvement rigide de la prostate, la dose a été calculée en utilisant la méthode XVMC, qui prend en considération la géométrie du patient, les hétérogénéités et les corrections pour le mouvement. Une déviation moyenne de la D95% de jusqu'à -11.9% a été observe pour le PTV, -5.1% pour le CTV et -4.2% pour le GTV. Le V95% du PTV a été réduit par un facteur de -22.2% lorsque la translation quotidienne de la prostate était présente mais aucune correction n'a été appliquée. La dégradation de la dose à la cible a pu être corrige presque complètement en appliquant une correction du mouvement de translation, cependant lorsque la rotation a été prise en compte, le recouvrement de la dose a été moins adéquat.
