What are the symptoms of a colonoscopy micro-perforation? how is it diagnosed, and does it require intervention ?

Microperforation: Though uncommon, this is not a rare problem associated with a very common and important procedure. Pain within a few hours, sometimes with fever, is an indication. Free abdominal air on a plain film is adequate to make the diagnosis. Usually, bowel rest and antibiotics will suffice, but occasionally surgical intervention will be necessary. Good luck.
