[Risk factors in emergency surgery relaparotomy].

Reintervention in abdominal surgery involves the difficulty of precise indication and the limitations of surgical technics during the operation. It may bring to evidence professional errors. It presents a very high morbimortality index. In order to establish risk factors and death rate, we comparatively analysed the initial diagnoses, the number, the cause and the time of relaparotomy, the existence of associated diseases, the age and the illness severity, using APACHE-II after the first surgical intervention. During a two years period starting 1990 we retrospectively analysed charts of 40 patients submitted to relaparotomy in the Emergency Service of Hospital das Clínicas of Medicine University of São Paulo.
