Paraesophageal hernia repair can decrease BNP levels.

Although the main manifestation of giant paraesophageal hernia (PEH) is disordered meal passage due to gastric torsion, the contents of the hernia sometimes squeeze the heart and lungs and induce the symptoms of respiratory or heart failure. Furthermore, the quality of life (QOL) of patients with a heavy cardiac load deteriorates. In this study, changes in a heart failure marker and symptoms of cases with a giant PEH from before to after laparoscopic surgery were examined. Levels of brain natriuretic peptide (BNP) as a heart failure marker were measured before and after radical laparoscopic surgery in cases of type III, IV type of giant PEH. Changes of the symptoms due to heart failure were also investigated. A total of 75 hiatal hernia surgeries were performed in 2012–2019. Of them, 50 had a giant PEH, and 20 (40.0%) had heart failure symptoms such as fatigue and exertional dyspnea. In the giant PEH cases, BNP could be measured before and after surgery to evaluate the presence of heart failure in 23 cases; postoperative BNP levels decreased from the preoperative values in 18 of them. Furthermore, in many cases, chest symptoms also improved. Radical laparoscopic surgery can reduce heart failure due to giant PEH. Therefore, in addition to conventional surgical indication criteria such as vomiting and food loss, increased cardiac load may be added to the new surgical indication criteria.
