Hiatus hernia


A hiatus hernia occurs where there is herniation of stomach through the esophageal hiatus of the diaphragm. It is sometimes wrongly considered synonymous with gastro-esophageal reflux disease (GERD) despite the poor correlation between the two.

  2. loculated empyema
  3. hydropneumothorax
  4. oesophagal obstruction
