Introduction. Knowledge of the risk factors that may lead to complications after emergency hernia repair is of great importance, as much for the prioritisation of the elective surgery, as selecting those cases that require clinical follow up. Objectives. To analyse the factors conditioning the morbidity and mortality of bowel resection associated to emergency hernia repair. Patients and method. A retrospective review was carried out on the clinical histories of patients who had emergency operations for hernia problems from January 2000 to December of 2005. The clinical results obtained were compared based on whether or not a bowel resection was required. Results. A total of 2367 patients were operated for hernia in this period, 362 of them (15.3%); for a complicated hernia (mean age 69.5 years; 146 males/216 females); 60 patients needed bowel resection. Complications appeared in 108 patients (29.8%) and 17 (4.7%) died after operation. The limit of 70 years discriminated a significantly greater mortality (> 70: 7% vs < 70 2%; p = 0.01). The group of patients who needed bowel resection showed differences in statistical analysis both in age (75.4 vs 68.3 years; p = 0.002), prevalence of complications (40.7% vs 6.2%; p < 0.0001), and mortality (20% vs 1.6%; p < 0.0001). The discriminant analysis identified bowel resection as the only predictive independent variable of mortality (λ Wilks = 0.89; p = 0.0001; predictive value, 85%). Conclusions. Morbidity and the mortality of urgent hernia surgery, when bowel resection was required, are elevated; especially in older patients, and in crural hernias.
