We report two patients who were administered to our hospital with an o
bstruction of the colon. 4 months ago one of the patients had suffered
a penetrating wound with a knife in the upper left abdomen. The other
patient was wounded by gunshot in the left thorax 50 years ago. The x
-ray of the lung showed the ruptured diaphragm as a sharp line in the
left thorax and the enema with contrast fluid revealed a stop at the l
eft colonic flecture. In both cases the rupture of the diaphragm was c
losed via an abdominal approach, the inspection of the colon did not d
iscover any defect, The postoperative course was uneventful. In contra
st to other authors we believe that the delayed rupture of the diaphra
gm in connection with a colonic obstruction should be repaired by an a
bdominal access.
