Uso de prótese biológica no tratamento cirúrgico de hérnias paracolostômicas

BACKGROUND: Paracolostomy hernia is a frequent complication of intestinal stoma. Its correction can be made through relocation of the colostomy or by keeping it in place and performing abdominal wall reinforcement through direct suturing with or without a prosthesis. METHOD: Results of surgical treatment of paracolostomy hernias were analyzed in 22 patients who underwent surgery in our hospital during the past 15 years, with or without biological mesh (bovine pericardium). All patients had terminal colostomies after abdominoperineal excision of the rectum. RESULTS: In 15 (68.2%) patients, hernia correction was made by maintaining the colostomy in place, in 2 of them (9.1%) without reinforcement, and in the other 13 (59.1%) through reinforcement of the aponeurosis with biological mesh. In the 7 (31.8%) other patients, hernia correction was accomplished by relocation of the colostomy. The mean follow-up period was 50.2 months. Recurrence was observed in 3 (13.6%) patients after a median of 16 months post-correction. CONCLUSION: Paracolostomy hernia remains a surgical challenge due to its high recurrence rate. Primary repair using a prosthesis of biological material may be preferable since muscle-aponeurotic weakness is frequently observed.Hérnias paracolostômicas são complicações freqüentes de estomas intestinais. A correção pode ser realizada através do seu reposicionamento ou mantendo a mesma localização, associada ao reforço da parede abdominal com ou sem o emprego de prótese. MÉTODOS: Os resultados do tratamento cirúrgico de hérnias paracolostômicas são analisados em 22 pacientes em nosso serviço nos últimos 15 anos. Todos os pacientes eram portadores de colostomias terminais após ressecção abdominoperineal do reto. RESULTADOS: Em 15 (68,2%) pacientes, a correção da hérnia foi realizada mantendo-se a colostomia no local original, em 2 (9,1%) deles através de herniorrafia simples e em 13 (59,1%) com reforço da aponeurose com prótese biológica. Nos outros 7 (31,8%) pacientes, a correção foi realizada por reposicionamento da colostomia. O seguimento médio pós-operatório foi de 50,2 meses. Recidiva foi observada em 3 (13,6%) casos (em média 16 meses após correção). CONCLUSÃO: A hérnia paracolostômica continua a ser um desafio cirúrgico devido a sua elevada recidiva. Correção primária com prótese pode ser favorecida, uma vez que freqüentemente se observa fraqueza da aponeurose

Manifestações extra-intestinais em doença de Crohn e retocolite ulcerativa: prevalência e correlação com o diagnóstico, extensão, atividade, tempo de evolução da doença Extra-intestinal manifestations Crohn disease and ulcerative rectocolitis: prevalence na correlation with diagnosis, extension, activity, disease evolution time

INTRODUÇÃO: Existe uma grande prevalência de manifestações extra-intestinais(MEI) em portadores de doença de Crohn(DC) e de retocolite ulcerativa(RCU), variando de 24 a 65%. OBJETIVO: Determinar a prevalência de MEI em RCU e DC, correlacionando com diagnóstico do tipo de doença inflamatória intestinal, extensão, tempo de evolução e atividade da doença. MÉTODOS: Mil pacientes foram avaliados no Hospital das Clínicas da FMUSP no período de 1984 a 2004. Foram estudadas manifestações articulares, dermatológicas, oftalmológicas, urológicas, hepáticas, pulmonares e vasculares. RESULTADOS: Foram estudados 468 pacientes com DC(46,8%) e 532 com RCU(53,2%). Encontrados 627 pacientes (59,2% com RCU e 66,7% com DC) com pelo menos uma forma de MEI. A média de tempo de doença dos pacientes com MEI foi de 10 anos. As MEI foram mais freqüentes após o início dos sintomas intestinais. CONCLUSÕES: Tanto na RCU quanto na DC,quanto maior a extensão da doença no cólon, maior a incidência de MEI. As manifestações urológicas foram mais freqüentes na DC. As manifestações articulares e dermatológicas foram mais prevalentes no sexo feminino nos dois grupos. Manifestações hepáticas foram mais prevalentes na DC. As manifestações articulares, dermatológicas e vasculares tiveram correlação com a atividade da doença intestinal em ambos os grupos.<br>INTRODUCTION: There is great prevalence of extra-intestinal manifestations (EIM) in Crohn's disease(CD) and ulcerative rectocolitis (UR), varying from 24 to 65%. AIM: To determine the prevalence of EIM in UR and CD, establishing a correlation with the diagnosis of the kind of intestinal inflammatory disease, extension, evolution time and disease activity. METHODS: One thousand patients were evaluated at the Hospital das Clínicas da FMUSP, along the 1984 to 2004 period. Articular, dermatological, ophthalmologic, urologic, hepatic, pulmonary and vascular manifestations were studied. RESULTS: 468 patients were studied with CD (46.8%) were studied and 532 with UR (53.2%). 627 patients found (59.2% with UR and 66.7% with CD) with at least one form of EIM. The average disease time of the EIM patients was of 10 years. EIM were more frequent after the beginning of the intestinal symptoms. CONCLUSIONS: Both in UR as in CD, the greater the extension of the disease in the colon, the greater is the EIM incidence. Urologic manifestations were more frequent in CD. Articular and dermatological manifestations were more prevalent in the feminine sex in both groups. Hepatic manifestations were more prevalent in CD. Articular, dermatological and vascular manifestations were related with the activity of the intestinal disease in both groups
