Perforated mediastinal gastric volvulus: an uncommon complication of hiatal hernia.

A woman in her 50s was admitted to the emergency department with a 3-day history of abdominal pain, mainly in the right hypochondrium, radiating to the back, associated with postprandial vomiting and dysphagia. The abdominal ultrasound study found no abnormalities. Laboratory tests showed increased C-reactive protein levels, creatinine and high white blood cell count without a left shift. Abdominal computed tomography scan exhibited mediastinal herniation, twist and perforation of the gastric fundus associated with air-fluid levels in the lower mediastinum. The patient underwent diagnostic laparoscopy requiring laparotomy conversion due to hemodynamic instability related to the pneumoperitoneum. During the intensive care unit (ICU) stay, thoracoscopy with pulmonary decortication was performed to treat complicated pleural effusion. After ICU and standard infirmary bed recovery, the patient was discharged from the hospital. This report illustrates a case of perforated gastric volvulus as the cause of nonspecific abdominal pain.
