Twenty-eight cases of ruptured diaphragm due to blunt trauma are repor
ted, including three with rupture on the right. Most of the patients w
ere young men and rupture was an isolated lesion in only 6 patients, a
ll others having multiple trauma. One patient died during surgery (3.6
%) and complications, mostly respiratory; occurred in 17 patients (60
.7 %). Mid-term functional digestive and respiratory sequellae were ev
aluated. The gravity of ruptured diaphragm is basically related to the
severity of the trauma and associated lesions. The diagnosis remains
unrecognized in an important number of cases emphasizing the importanc
e of repeated chest X-rays.
