A ÍncontÍnência fecal apresenta baixa morbidade; pode estar associada à depressão, ao pessimismo e à dimÍnuição da auto-estima, levando à limitação das atividades da vida diária. Dentre as várias causas da ÍncontÍnência fecaI, a multiparidade e o parto vaginal são considerados fatores de risco significativos. Como opções de tratamento conservador para a ÍncontÍnência fecal tem-se a cÍnesioterapia clássica, o biofeedback e a eletroestimulação, dos quais espera-se aumento do tônus da musculatura esfincteriana e conscientização sensório-motora, permitÍndo ao paciente maior controle sobre sua defecação. o objetivo deste estudo foi comprovar a eficácia da eletroestimulação neuromuscular em pacientes multíparas com ÍncontÍnência fecaI, em estudo comparativo com o tratamento pelo biofeedback isolado ou deste associado à eletroestimulação. Foram estudadas 25 doentes multíparas portadoras de ÍncontÍnência fecaI, e estas foram divididas, mediante sorteio, em três grupos: oito doentes foram submetidas à eletroestimulação; oito, foram tratadas com o emprego da eletroestimulação com biofeedback e nove foram submetidas ao biofeedback. As doentes foram avaliadas pelos seguÍntes parâmetros: manometria anorretal, escore do índice funcionaI clínico de ÍncontÍnência fecaI e questionário de qualidade de vida e tempo de urgência de evacuação, perda de fezes durante o repouso, durante atividades da vida diária, perda de fezes andando, durante esforço leve, moderado, Íntenso e perda de fezes sem perceber, pré e póstratamento. Foi considerada também a estimativa de melhora e o grau de satisfação com o tratamento. O estUdofoi prospectivo e randomizado. A análise dos dados demonstrou diferença estatisticamente significativa entre o pré e pós-tratamento, Índependentemente do grupo estudado, nas variáveis referentes à área sob o traçado da contração voluntária, escore do índice funcional da ÍncontÍnência fecaI, ao escore da qualidade de vida, tempo de urgência de evacuação, perda de fezes durante repouso,duranteatividadesda vidadiária,perdade fezesandando,perdade fezesduranteo esforço moderado e perda de fezes sem perceber. Houve correlação estatisticamente significativa entre o pré e pós-tratamento no grupo de biofeedback, quando se comparou o valor da pressão anal média da contração voluntária máxima. Já a pressão anal média de repouso, a capacidade de sustentação e a perda de fezes durante esforço intenso não apresentaram nenhuma diferença com significância estatística. Os resultados obtidos neste estudo permitem concluir que a eletroestimulação é eficaz no tratamento da incontinência fecal em doentes multíparas, quando aplicada isoladamente ou em associação com tratamento pelo biofeedback. Estatisticamente não foi constatada superioridade entre os métodos / Abstract: Defecation is a private function and its occurrence at an undesirable moment or place can be embarrassing and lead to a condition of social alienation. Although fecal incontinence does not present a high mortality rate, it causes social and moral perturbations which are difficult to solve. It is an embarrassing condition with important socioeconomic repercussions. It can be associated with depression, pessimism and a drop in the patient self-esteem, leading to restrictions in day-to-day activities. Among the several causes of fecal incontinence, multiparity and vaginal delivery has been implicated as a significant causal factor. Options for the conservative treatment of fecaI incontinence include classical cinesiotherapy, biofeedback and electrostimulation ITomwhich the increase ofthe sphincter muscle tonus as well as of sensorial awareness are expected, resulting in a better defecation control. The aims ofthis study were to prove the efficiency ofneuromuscular electrostimulation in patients with fecal incontinence in comparison with patients treated by biofeedback and patients treated with electrostimulation plus biofeedback. In order to get a homogeneous group, twenty-five females and muhiparas patients sufIering ITom fecal incontinence were allocated to three groups to be submitted to treatment; 8 patients underwent electrostimulation, 8 patients underwent electrostimulation plus biofeedback and 9 patients were submitted to biofeedback alone. The patients were evaluated by anorectal manometry, by a clinical functional index of fecal incontinence, by a questionnaire about their quality of life, time of evacuation urge, loss of feces during rest hours, daily activities , walking, during light, moderate or intense efIort as well as loss of feces without noticing pre- and post-treatment. The patient's evaluation of their improvement and satisfaction degree has also been analyzed. This study was prospective and randomized. The Analysis of the data demonstrated statistically significant difIerences independent of the group assessed between the pre- and post-treatment scores of functional index of fecal incontinence, the quality of life assessments, the area under graphic traces of voluntary squeeze and the times of urgency of evacuation, loss of feces during rest hours, daily actives, waIking, during light or moderate or effort as well as 10ss of feces with out noticing. There was a statistically significant correlation between the pre- and post-treatment in the biofeedback group when comparing the mean anal pressure of maximum voluntary squeeze. However, the mean resting anal pressure and the capacity of sustentation and the 10ss of feces during intense effort did not present any significant difference. The results obtained in the present study enabled us to conclude that electrostimulation is as . etlicacious as biofeedback in the treatment of fecal incontinence, without giving a statistically significant difference between the two methods / Mestrado / Pesquisa Experimental / Mestre em Cirurgia

Nessa perspectiva, o cu tem sido utilizado, metaforicamente, em discussões político-epistemológicas que reivindicam a desconstrução da norma heterossexual contribuindo para a produção de saberes implicados pela erotização corporal, como também, para a criação de políticas que privilegiam o prazer anal e criticam a reprodução da divisão “norte-sul”, no âmbito das teorizações queer. No entanto, as metáforas, muitas vezes, parecem produzir certa facticidade do uso sexual anal, relacionado à penetração e à passividade. A encenação do prolapso no pornô, quase exclusivamente realizado por atrizes, nos fez questionar se a pornografia pode ir além do sentido de “pedagogia sexual” e caracterizar-se como um campo de potência imaginativa e, nesse caso, de criação de possibilidades corporais que desafiam verdades anatômicas e fisiológicas. Nos interrogarmos também sobre o fato de que a penetração anal seja comumente o único referente do prazer sexual anal e, consequentemente, a base para que se possa pensar as relações sexuais a partir da binaridade “atividade/passividade”. Assim, elegemos como objetivo primordial analisar as disposições de sexualidade e erotismo acionadas pelo prolapso pornográfico no site prolapseparty.com. O material de pesquisa constituiu-se de textos, elementos gráficos e vídeos apresentados no site Prolapseparty.com que foram problematizados a partir de uma perspectiva pós-estruturalista de inspiração Foucaultiana. Consideramos que as fantasias nesse site podem ser vivenciadas pela criação de elementos que incentivem a imaginação de que os atos sexuais podem ir além da tela do computador e fazer parte do cotidiano. Os usos sexuais do ânus, nesse sentido, não envolvem a penetração ou a inserção anal, mas, a exploração da capacidade de elasticidade e excrescência que levou-nos a argumentar que as imagens engendram “prazeres sexuais de superfície”. Outro elemento importante foi a menção à relação de proximidade entre as atrizes que funciona como forma de denotar que o deleite sexual proporcionado pelo deslocamento do reto se diferencia de um ato de “violência”. Assim, a exibição das técnicas que deslocam e criam genitálias e ânus prolapsados abdicam da naturalidade corporal e, consequentemente, enfatizam que o prazer sexual é fabricado. / The "anal subject" is revealed as the scientific epistemologies criticism which assumes that neutrality and universality are attributes embracing both those who produce knowledge as well as what is produced. In this perspective, the asshole has been used, metaphorically, in political and epistemological debates which clames for deconstruction of the heterossexual standards and contributes to production of knowledges involved by the body erotization, and also to the creation of policies that privileges anal pleasure and criticizes the reproduction of "north-south" division in Queer Theories. However, the metaphors often seems to produce certain facticity of sexual anal uses, often related to penetration and passivity. The enactment of prolapses in pornography, almost exclusively performed by actresses, made us wonder if pornography can go beyond the meaning of "sexual pedagogy" and going to be characterized as a field of imaginative power and creation of bodily possibilities that challenge anatomical and physiological truths. We ask also about the fact that anal penetration is commonly the only referent for sexual anal pleasure and, consequently, the basis to think about the sexual relations from the "activity/passivity" binarity. Thereby, we chose as the primary objective to analyze the sexuality and eroticism provisions which are driven by pornographic prolapse at the website prolapseparty.com. The research material was consisted of texts, graphics and videos on this website contents and were debated from a post-structuralist perspective, inspirated by Foucault's theories. We believe that the fantasies in this website contents may be experienced by the creation of elements that encourage imaginations about sexual acts going beyond the screen of the computer and being part of everyday lifes. The sexual uses of the asshole does not involve the penetration or the anal insertion, but the holding capacity of elasticity and excrescence, wich have led us to argue that those images engender "sexual pleasures of surfaces". Another important element to mention is the close relationship between the actresses as a way to denote that the sexual pleasure provided by the displacement of the rectum is different from an act of "violence". Finally, the exhibition of techniques that moves and creates genitals and prolapsed anus abdicates from the body naturally and consequently emphasizes that sexual pleasure is manufactured.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Anismus 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 87.28  0.80 (76,5Â-96,2Â) and of 87.87  0.99 (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 93.25  1.49 (74,9Â-106,9Â) and of 85.27  1.35 (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 62.61  1.15 (50,9Â-75,0Â) and of 65.51  0.89 (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 59.75  1.42 (44,0Â-73,0Â) and of 69.40  1.06 (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

Les cancers viro-induits dont le chef de file est le cancer du col utérin lié aupapillomavirus humain (HPV) représentent une cause importante de mortalité dans la Caraïbe. Ilsont récemment été désignés comme objectif de santé publique par les registres des cancers antillais.Pour autant, les données virologiques disponibles sont rares et concernent principalement lesantilles anglophones. Des études de répartition génotypique menées à Tobago, en Jamaïque et à laBarbade montrent, en population générale, une forte prévalence des infections par les HPV à hautrisque oncogène (HRHPV) et une prédominance de génotypes différents de ceux qui prévalent dansles pays du nord (i.e.: HPV16, HPV18) notamment les génotypes HPV45 et HPV58. Ces donnéessoulèvent la question de l’existence d’un profil de distribution génotypique particulier dans laCaraïbe et la nécessité, le cas échéant, d’adapter la stratégie de prévention vaccinale des infectionspar les HPV à haut risque oncogène car les vaccins actuels ne ciblent que les génotypes 16 et 18 .Objectifs : L’objectif principal du travail était de décrire la distribution génotypique (estimation dela prévalence des différents génotypes) des HPV oncogènes impliqués dans les infections de lasphère ano-génitale des femmes, en Guadeloupe. L’objectif secondaire était de préciser les facteursdémographiques, sociaux et cliniques associés à la présence d’une infection ano-génitale à HPVoncogène.Patients et méthodes : Trois études ont été envisagées : i) une étude rétrospective, en populationgénérale, à partir des données cytologiques et virologiques du cabinet de pathologie de Guadeloupedont l’activité est la plus intense dans le domaine ciblé, ii) deux études prospectives conduites chezdes femmes immunodéprimées, soit par une transplantation rénale, soit par une maladie systémiqueauto-immune. Cette population de femmes a été choisie car elle est caractérisée par une prévalenceélevée d’infections ano-génitales à HPV oncogènes et une fréquence importante de complicationscarcinologiques HPV-induites, documentée dans la littérature.8prévalence des HPV à haut risque oncogène de type ni 16 ni 18 comme en atteste la distributiongénotypique observée en population générale et en population immunodéprimée (i.e. prévalenceforte du type HPV52 et à moindre degré des types HPV39 et HPV51 chez les patientestransplantées et des types HPV31, HPV58, HPV39, HPV45 chez les patientes présentant unemaladie systémique auto-immune). Ces résultats confortent les données des études précédemmentconduites dans l’arc antillais et constituent un argument pour élargir la protection vaccinale anti-HPV aux types non 16 non 18, dans le but d’ optimiser la prévention primaire du cancer du colutérin, aux Antilles.Le vaccin anti-HPV nonavalent, de commercialisation récente, semble représenter une optionintéressante. En effet, les 5 types supplémentaires de HRHPV qu’il cible par rapport aux vaccins de1ère génération (i.e.: HPV31, HPV33, HPV45, HPV52, HPV58) correspondent aux types despapillomavirus humains à haut risque oncogène ni 16 ni 18 qui circulent activement dans laCaraïbe, y compris deux types impliqués dans les cancers invasifs du col utérin aux antillesfrançaises: HPV33 et HPV45.Les facteurs de risque d’infection par les HPV oncogènes identifiés dans notre travailcorrespondent aux facteurs largement documentés dans la littérature comme le début précoce desrapports sexuels ou le statut de célibataire. Une étude de plus grande envergure est nécessaire pourinvestiguer l’association avec la sclérodermie systémique. / Of the virus-related cancers, cervical cancer linked to the human papillomavirus(HPV), is one of the leading causes of mortality in the Caribbean. These cancers have recently beenidentified as an important public health problem by Caribbean cancer registries. However,virological data available are limited and related primarily to the English-speaking Caribbean.Genotypic distribution studies in Tobago, Jamaica and Barbados show a high HPV prevalence ofhigh-risk HPV types (HR HPV) infections in the general population and a predominance ofgenotypes different from those of northern countries (i.e.: HPV16 and HPV18) in particular typesHPV45 and HPV58. These data raise the question of the existence of a specific genotypicdistribution profile in the Caribbean and the need, if required, to adapt vaccine prevention strategyagainst HRHPV infections because current vaccines only target genotypes 16 and 18.Objectives: The main objective of this study was to describe the distribution of carcinogenic HPVtypes involved in anogenital infections of women in Guadeloupe. The second objective was toidentify the demographic, social and clinical factors associated with the presence of oncogenic HPVinfection of the anogenital area.Patients and methods: Three studies were conducted: (i) a retrospective study concerning thegeneral population based on cytological and virological data from the Guadeloupe pathologylaboratory whose activity is the most intense in the targeted field; (ii) two prospective studies inwomen immunocompromised (i.e.: kidney transplant recipients, autoimmune systemic disease).This population of women was chosen because it is characterized by a high prevalence of HPVanogenital infections with frequent HPV-induced mucosal cancer complications reported in theliterature.Our 3 studies show a high prevalence of anogenital infections with carcinogenic HPVin women on the island of Guadeloupe. This high prevalence appears to be directly linked to theprevalence of high-risk, oncogenic HPVs of type non 16 and non 18, as evidenced by the genotypicdistribution observed in the general population and the immunocompromised population (i.e. HPV52 , HPV39, HPV51 in kidney transplant recipients and HPV31, HPV58, HPV39, HPV45 inpatients with autoimmune systemic disease). These results are in accordance with data from studiespreviously carried-out in Caribbean. They constitute an argument for extending the protectionagainst non-16 and non-18 HPV types infections with the aim of optimizing the basic prevention ofcervical cancer in the caribbean countries. The nonavalent new HPV vaccine seems to constitute aninteresting option. The 5 additional types of HR HPV that it targets compared to first generationvaccines (i.e.: HPV31, HPV33, HPV45, HPV52, HPV58) correspond to high risk HPV types nor16nor18 that are actively marketed in the Caribbean, including two types involved in invasive cervical11cancer in the French West Indies: HPV33 and HPV45.Risk factors for HPV infection identified in our study correspond to factors widely documented inthe literature such as early onset of sexual intercourse or unmarried status. A larger study is neededto investigate the association with systemic sclerosis.

A exenteração pélvica é método efetivo no tratamento de tumores pélvicos localmente avançados. As cirurgias mais conservadoras, com preservação funcional dos esfíncteres e reconstrução continente dos tratos intestinal e urinário podem melhorar a qualidade de vida e estimular os pacientes a aceitar a cirurgia. O objetivo deste estudo foi avaliar os resultados da exenteração pélvica no tratamento dos tumores pélvicos localmente avançados em relação à preservação dos esfíncteres e fatores associados ao prognóstico. Analisou-se retrospectivamente os fatores relacionados à preservação dos esfíncteres bem como os fatores associados ao prognóstico em pacientes submetidos à exenteração pélvica. Dos 96 pacientes submetidos à exenteração pélvica, preservou-se pelo menos um dos esfíncteres em 36 (37,5%). Na década de 1990 a taxa de preservação esfincteriana foi significativamente maior do que na década de 1980 (47,6 versus 18,2%) (p = 0,005). As variáveis independentemente relacionadas à preservação de esfíncter foram tratamento realizado na década de 1990 e tumor de origem coloproctológica. A taxa de complicação pós-operatória não foi influenciada pela preservação dos esfíncteres (p = 0,276). Não se observou diferença estatisticamente significativa nas taxas de morbidade entre as décadas de 1990 e 1980 (55,6% versus 75,8%; p = 0,075). Na década de 1990 houve redução da taxa de mortalidade pós-operatória em relação à década de 1980 (9,5% versus 27,3%; p = 0,023). Em nove pacientes, as margens de ressecção estavam microscopicamente comprometidas (R1) e, em cinco macroscopicamente comprometidas (R2). As margens de ressecção não foram influenciadas pelo tipo de cirurgia (p = 0,104), nem pela preservação dos esfíncteres (p = 0,881). A taxa de sobrevida livre de doença em cinco anos foi de 40,5%. Observou-se associação da recorrência com perda de peso (p = 0,006), índice de Karnofsky (p = 0,035) e a topografia do tumor (p = 0,027). No modelo multivariado, a perda de peso e os tumores de origem ginecológica foram as variáveis independentes para recorrência. Pacientes portadores de tumores ginecológicos ou com perda de peso foram considerados de alto risco para recorrência e os pacientes portadores de tumores não ginecológicos e sem perda de peso, de baixo risco. O grupo de alto risco apresentou chance de recorrência cerca de sete vezes maior do que o de baixo risco. A sobrevida livre de doença em 5 anos para os grupos de baixo e de alto risco foram, respectivamente, de 78,0% e 21,2%. As variáveis associadas ao óbito foram a idade superior a 60 anos (p = 0,007), a perda de peso (p = 0,004), radioterapia pré-operatória (p = 0,043), década de trata mento (p = 0,050) e preservação de esfíncter (p=0,026). No modelo multivariado as variáveis associadas ao óbito foram tratamento realizado na década de 1980, a idade superior a 60 anos e a perda de peso. Com os resultados deste estudo podemos concluir que houve aumento significante da preservação dos esfíncteres na década de 1990 sem aumento da freqüência de margens cirúrgicas comprometidas nem prejuízo na sobrevida dos pacientes submetidos à exenteração pélvica com preservação dos esfíncteres / Pelvic exenteration (PE) is an effective method for treating locally advanced pelvic tumors. More conservative surgeries, preserving sphincters and continent reconstruction of the intestinal and urinary tract, which could contribute to a better quality of life and encourage patients to accept this procedure. The objective of this study was to evaluate the results of PE in the treatment of locally advanced pelvic tumors, mainly considering sphincter preservation and factors associated to the prognosis. Between 1980 and 2000, 96 PE were performed. Factors related to sphincter preservation as well as factors associated to prognosis were respectively analyzed. Of the 96 patients treated with pelvic exenteration, at least one sphincter in 36 patients was preserved (37.5%). In the 1990\'s, the sphincter preservation rate was significantly higher than in the 1980\'s (47.6 vs. 18.2 %) (p = 0.005). Independent variables related to the sphincter preservation were decades from the realization of surgery 1990\'s and coloproctological tumors. The postoperative complication rate was not influenced by sphincter preservation (p = 0.276). Statistically, there was no differentiation between the morbidity rates during the 1980\'s and 1990\'s (55.6% versus 75.8%, p = 0.075). In the 1990\'s, there was a reduction in the post-operative mortality rate compared to the 1980s\' rate (9.5% versus 27.3%; p = 0.023). In nine patients, the resection margins were compromised microscopically (R1) and in five patients, macroscopically compromised (R2). The resection margins were not influenced by the type of surgery (p = 0.104), nor by the preservation of sphincters (p = 0.881). Disease free survival at five years was 40.5%. Among the clinical variables, there was an association between recurrence and weight loss (p = 0.006) and the Karnofsky index (p = 0.035). The topography of the tumor showed links with recurrence (p = 0.027). In the multivariable model, the independent variables related to recurrence were weight loss and gynecological tumors. Patients with gynecological tumors or with weight loss were considered high risk for recurrence, while patients with no gynecological tumors and without weight loss were considered low risk. The high risk group showed 7 times more chance of recurrence than the low risk group. Survival rates of patients, who remained disease-free, after 5 years, for the low and high risk group were 78.0% and 21.2% respectively. Death was linked to ages over 60 (p = 0.007), weight loss (p = 0.004), pre-surgery radiotherapy (p = 0.043), decades from the realization of surgery (p = 0.050) and the sphincter preservation (p = 0.026). The independent variables related to death were treatments in the 1980\'s, ages over 60 and weight loss. Taking into account the results in this research, we conclude that there was a significant increase of sphincter preservation during the 1990\'s and neither the type of surgery nor sphincter preservation were associated to a higher number of surgeries with compromised margins allows pelvic exenteration to be performed with sphincter preservation, without harming survival rates
