An accurate preoperative evaluation of severity factors might allow stratification of patients in terms of their mortality risk and help in the decision-making process for treatment. Such an evaluation would also enable better comparison between studies performed by different authors. Principles and stratification similar to those of distal lesions should be considered in patients with proximal colonic obstruction.
