[Scoring systems for postoperative mortality in left colonic peritonitis]

Left colonic perforation is associated with high mortality and morbidity. The identification of risk factors for postoperative mortality led to the development of scoring systems with prognostic values that have been used in various clinic situations and some of which were designed specifically for surgical patients. Severity index allows the mortality and morbidity risk to be quantified and predicted based on physiological, analytical or clinical factors; its application is a valid and rigorous method to calculate the probability of complications and postoperative death. The use of a score system that can provide an objective assessment of individual postoperative death risk is an important aid for an accurate planning of treatment and for management of health resources, mainly where patients may need intensive care.
