Purpose
The precise importance of factors affecting morbidity and mortality in patients with complicated abdominal wall hernias undergoing emergency surgical repair has been not completely elucidated.
Patients and methods
A retrospective multicentric study of all patients (n = 402) with abdominal wall hernia who underwent urgent operations over 1-year period was conducted in ten hospitals. Logistic regression analysis was used to evaluate variables that affect morbidity and mortality.
Results
Thirty-five percent of patients had inguinal hernia, 22% femoral hernia, 20% umbilical hernia, and 15% incisional hernia. Mesh repair was used in 92.5% of cases. Intestinal resection was required in 49 patients. Perioperative complications occurred in 130 patients, and 18 patients died (mortality rate 4.5%). Complications and mortality rate were significantly higher in the group of intestinal resection. Patients older than 70 years also showed more complications, required intestinal resection more frequently, and had a higher mortality rate than younger patients. In the logistic regression analysis, age over 70 years, intestinal resection, and American Society of Anesthesiologists (ASA) III/IV class emerged as independent predictors of a poor outcome. Based in our results, we propose a simple schema to calculate risk of death in these patients.
Conclusion
Using multivariate logistic regression analysis, probabilities of death after complicated abdominal wall hernia surgery are increased in patients with: age over 70 years, high ASA class, and associated intestinal resection. Guidelines should be developed to improve prognosis in these patients.
