-Background -The correction of abdominal hernias remains one of the most common surgical procedures since it occurs in about 11% of laparotomies. There are several risk factors. Arise, in general, the first five years after the operation and their management is controversial. Aim -Update the means and methods for surgical repair of giant abdominal hernias. Method -Literature review based on PubMed, Lilacs and Scielo with crossing the keywords "abdominal hernia, prostheses, surgical techniques and complications", and adding its own contribution based on the authors' experience in handling this condition. Conclusion -Even the successful correction with the use of large prostheses, may happen procedure inconvenient, because the abdominal wall does not resume its elasticity and compliance at the normal. For this reason, it is important that the patient be advised of the possibility of their expectations regarding the outcome, both aesthetic and functional, not be achieved.RESUMO -Introdução -A correção de hérnias incisionais abdominais permanece como um dos procedimentos cirúrgicos mais comuns uma vez que ela ocorre em cerca de 11% das laparotomias. Vários são os fatores de risco. Surgem, em geral, nos primeiros cinco anos após a operação e seu manuseio ainda é controverso. Objetivo -Atualizar os meios e métodos empregados para a correção cirúrgica das hérnias abdominais gigantes. Método -Revisão da literatura com base no Pubmed, Scielo e Lilacs com cruzamento dos descritores "hérnia abdominal, próteses, complicações e técnicas cirúrgicas", e adicionando contribuição própria baseada na experiência dos autores no manuseio desta afecção. Conclusão -Mesmo as correções bem sucedidas, com a utilização ou não de grandes próteses, não são os procedimentos isentos de inconvenientes, pois a parede abdominal não retoma a sua elasticidade e complacência normais. Por este motivo, é importante que o paciente seja alertado da possibilidade da sua expectativa em relação ao resultado, tanto estético quanto funcional, não ser alcançada.
. headings -Stomach Neoplasms. Helicobacter pylori.abstRact -Background -Etiology of gastric cancer (GC) remains controversial and several factors have implicated in its carcinogenesis process, including Helicobacter pylori (Hp) infection. Hp infection's role on GC remains uncertain, with several conflicting studies. Aim -To look for any correlation between H. Pylori and gastric cancer fom gastric specimen after gastrectomy. Method -Ninety-one patients with diagnosis of adenocarcinoma of the stomach treated by surgical resection were reviewed. Pathological examination was repeated in all patients to determine the presence of Hp infection, intestinal metaplasia (IM) and confirmation of the hystologic type by conventional haematoxylin-eosin staining. Statistical analysis was performed using Chi-quadrate and log-rank tests. Results -IM was observed in 81 tumours (89%). Overall, the presence of Hp infection was observed in 46 tumours (50.5%). There was no association between age and Hp status. In the group of patients with early and advanced GC, Hp infection was present in 47.7% and 54% of tumours. Hp infection was present in 40 tumours (49%) in the group of patients with IM. In patients with tumours without IM Hp was present in five (50%) tumours. Proximal tumours had more Hp infection when compared to distal tumours. Conclusions -The infection rate had no significant association with histologic type, IM, gender or stage. These results may indicate that participation of Hp infection during GC development cannot be ruled out; however, it is probably not essential during all stages of GC development and the mechanism may be distinct of the chronic gastritis and IM progression. Finally, it is possible that the proposed association is merely coincidental and that there is no actual influence of the bacteria in the carcinogenesis process.Resumo -Racional -A causa do câncer gástrico (CG) é controversa e tem vários fatores envolvidos no seu processo de carcinogênese, incluindo o Helicobacter pylori (Hp) O papel da infecção pelo Hp no CG permanece incerto, com vários estudos controversos. Objetivo -Correlacionar a presença da infecção pelo Hp com câncer gástrico, através de exame anatomopatológico convencional do estômago ressecado. Método -Noventa e um pacientes tratados por ressecção cirúrgica foram revistos. O exame anatomopatológico foi feito em todos os pacientes para determinar a presença de infecção por Hp, metaplasia intestinal (MI) e confirmação do tipo histológico por hematoxilina-eosina. A análise estatística foi realizada através do qui-quadrado e testes de log-rank. Resultados -MI foi observada em 81 tumores (89%). Em geral, a presença de infecção pelo Hp foi observada em 46 casos (50,5%). Não houve associação entre idade e Hp. Nos grupos de pacientes com CG avançado e precoce, a infecção pelo Hp estava presente em 47,7% e 54% dos tumores. A infecção pelo Hp ocorreu em 40 tumores (49%) no grupo de pacientes com MI. Nos com tumores sem MI, Hp estava presente em cinco (50%). Tumores proximais tiveram mais infecç...
