Abstract
A 88-year-old woman referred for appetite loss and vomiting was found on abdominal computed tomography (CT) to have a hernia through the foramen of Morgagni prolapsed with the transverse colon and omentum, with stenotic sigmoid colon cancers further detected. We suspected a strangulated Morgagni's hernia and performed emergency surgery. Laparotomy disclosed a hernia located at the foremen of Morgagni with a sac containing the transverse colon, jejunum and omentum. After removal of the sac manually, the hilum was closed with a continuous suture. In addition, Hartmann's operation was performed based on the diagnosis of a large bowel obstruction by sigmoid colon cancer. These findings can be justified since the ileus symptoms of Morgagni's hernia were potentiated by increased large bowel pressure due to stenosis by the sigmoid colon cancer. We report herein on this rare case in which Morgagni's hernia was complicated with sigmoid colon cancers, together with a review of the literature.
