The modifications suffered by the peri-esophageal anatomical structures in the hiatal hernia disease: a qualitative and quantitative microanatomic study.

This paper presents the results of a surgical and histopathological study regarding the microanatomical modifications of the thoraco-abdominal diaphragm and of the peri-esophageal structures in the hiatal hernias, establishing a cause-effect relationship between these structural modifications and the hiatal hernia. The study was represented by two groups of patients: a control group and a group with hiatal hernia. The study method consisted in intraoperatory biopsy of fragments from the diaphragm as well as from the tissue around the esophagus, which were studied from the histopathological viewpoint, using histological methods and quantitative microanatomy.
