To the Editor,

We read with great interest the article by Dr. Cox and colleagues, entitled “Bowel obstruction complicated by ischemia: analysis of CT findings”, on 173 cases of patients with surgical bowel obstruction, 37 of them complicated with bowel ischemia [1].

Bowel obstruction is a common cause of acute abdomen in the emergency setting, especially due to occlusion of the small intestine, and may complicate with bowel wall ischemia and necrosis, or perforation. Approximately, 7% to 42% of bowel obstructions could be complicated by ischemia, which can require urgent surgical intervention. We agree with the conclusion reported by Authors, stating that hypoenhancement, bowel wall thickening and pneumatosis are useful, highly specific CT signs of bowel ischemia in the setting of surgical obstruction, similar to the non-obstructive setting [1].

However, from a radiological point of view, we would like to stress two different messages for radiologists focusing on the association...
