Late colonic obstruction after barium meal examination in a myxoedematous patient.

A case in which inspissated barium was retained and produced sigmoid obstruction after one year is described. The patient was elderly and myxoedematous. Prolonged retention of barium producing a bowel obstruction requiring surgery is a rare complication and, to our knowledge, is only the second case described in which the symptoms of obstruction appeared so late after the examination.

Diaphragmatic herniation of the large bowel associated with unusual clinical and electrocardiographic presentation.

This is the first case reported of combined hiatus hernia of the stomach and herniation of the splenic flexure of the colon through the oesophageal hiatus. It was associated with unusual clinical and electrocardiographic findings. We postulate that these were the result of an increase in intrathoracic pressure induced by the herniating structures.
