[Iatrogenic injuries to the colon].

The authors examine a number of aetiological, diagnostic and therapeutic aspects of iatrogenic injuries to the colon on the basis of an analysis of their own experience and a review of the literature. They highlight the low incidence of this kind of injury, which accounts for only 0.3% of all visceral injuries. Endoscopy and laparoscopic surgery are the most important causes of iatrogenic injuries to the colon. The authors conclude that these injuries are less serious and have a better prognosis than other kinds of colon perforations, because the colon is "clean" and it is possible to obtain an early diagnosis. Exceptions are lesions that occur in the course of a barium enema since these are associated with a high mortality rate which in some series may be as high as 100% of cases owing to the high toxicity of the barium contrast medium.
