Could Forming a Stoma Alongside from the Principal Surgery Predict Mortality Among Operative Parameters?

Stoma surgery is a more morbid procedure in colorectal surgery, compared to other procedures. In the predictive scoring systems, the mortality associated with colorectal surgery is evaluated by a combination of physical and operative parameters; however, stoma surgery is not addressed individually among the operative parameters. This study aims to determine whether the surgeons, who decide in the formation of stomata, own an acquired ability to predict mortality. Four hundred thirteen patients who underwent ileostomy and colostomy formation were included in the study. All patients were evaluated in two time periods: the first 30 days after surgery (short) and in the long term. As a result, short- and long-term mortality rates were observed to be high with statistical significance. When the patients with various etiologies but with the same surgery conditions, in the short term, no statistical differences were observed in the mortality rates statistically; however, by the multivariate analysis, the mortality rates were found to be 1809 times more in patients with benign etiologies. High mortality rates with statistical significance were observed in the long term in patients with malignancies. In conclusion, the decision on stoma requirement is a predictor of mortality both in the early period and in the long term. Stoma must be included in the future colorectal surgery mortality prediction scoring systems, individually and aside from the surgical intervention, as a factor increasing the potential for mortality.
