title: Natural course of penetrating diaphragmatic injury: an experimental study in rats.
abstract: There are controversies about the fate of penetrating diaphragmatic injuries not diagnosed and treated. The objective was to evaluate the evolution of untreated diaphragmatic injury on an experimental model. Fifty-six rats suffered diaphragmatic injuries. Two groups were submitted to sternotomy and laparotomy--A (at 11-60 days) and B (at 120-160 days)--and all animals underwent diaphragm anatomopathologic analysis. The macroscopic results revealed diaphragmatic hernia in five animals (8.9%). Our results showed that histologic response was not the factor for this occurrence. We conclude that spontaneous healing of diaphragmatic injury occurs naturally.
