Non traumatic right Bochdalek hernia with loss of Domain in adults. Our experience and review of literature.

INTRODUCTION

Right-sided Bochdalek hernia (BH) is a rare developmental defect in the posterolateral diaphragm, allowing herniation of abdominal contents into the thorax. To date only 44 reported cases of right-sided BH have been surgically managed in adults in literature. We report one additional case of right-sided BH with loss of Domain. "Loss of domain" (LOD) is a term used commonly in the hernia literature to describe the distribution of abdominal content between the hernia and residual abdominopelvic cavity. After repairing hernias with significant LOD, serious physiological complications can arise.

METHODS

PubMed and Cochrane bibliographical databases were searched (last search: February 2022) for studies concerning BH.

CASE PRESENTATION

We report the case of a 50-year-old woman whose right-sided diaphragmatic hernia strangulated loops of small bowel and who was thus treated via urgent laparoscopy. After reduction of the intrathoracic contents we were unable to primarily close the midline fascia.We performed a staged abdominal wall reconstruction as the chronicity of the hernia led to loss of intra-abdominal domain.

DISCUSSION

Bochdalek hernia (BH) is the most common type of congenital diaphragmatic hernia and is usually leftsided. It typically presents in neonates and diagnosis in adults is a rarity. Various surgical repair options include open surgery, laparoscopic repair, thoracoscopic approach and robotic transthoracic approaches.

CONCLUSION

BH should be managed timely regardless of its symptoms to avoid future complications. The closure of the defect can be done by different methods. When, after diaphragmatic hernia repair, it is suspected that the herniated viscera have lost their domain, it is preferable to use a Temporary Abdominal Closure to prevent compartment syndrome.
