Strangulated hernia of the foramen of Morgagni: introducing a principle for the reduction of obstructed intraabdominal hernias.

Comments are made on diaphragmatic hernias in general, and hernia of the foramen of Morgagni in particular. A case history is recorded of strangulation of such a hernia in a man of 76 years. Reduction of the entrapped colon was effected by intraluminal suction-decompression across the neck of the hernia. Search of the literature suggests that this principle is an innovation, and that it is an important manoeuvre for the management of any obstructed intraabdominal hernia where there is technical difficulty in its reduction.
