The authors report the case of a 75 year-old woman admitted to the emergency room with abdominal pain and coffee ground vomiting. Marked epigastric distension with tenderness and signs of severe dehydration were present. Upper GI endoscopy showed a black esophagus covered by a large amount of dark fluid, diffuse hyperaemia and superficial erosions. Marked distortion of gastric anatomy caused by stomach rotation and a large paraesophageal hernia was observed and the pylorus was not identified. Chest X-ray and CT scan confirmed the presence of an organoaxial gastric volvulus with antero superior rotation and incarceration of the gastric antrum, which was located above the diaphragm. Immediate surgery repaired the diaphragmatic hernia, obtained volvulus reduction and a Nissen fundoplication was performed to prevent recurrence. The patient was discharged without further complications. Acute gastric volvulus is a rare entity that may manifest with vomiting due to gastric outlet obstruction and gastrointestinal bleeding associated with mucosal ischemia and sloughing. Emergency surgery wass required to resolve symptoms and prevent complications.

A hiatal hernia is a condition in which intraabdominal content herniates into the intrathoracic cavity. On rare occasions, a hiatal hernia can lead to cardiorespiratory compromise. We report a case of chest pain followed by cardiac arrest in a patient not known to have hiatal hernia, and without preliminary symptoms. The patient was suspected of having cardiac ischemia; however, angiography did not reveal any abnormalities. Chest tomography revealed a large paraesophageal hernia with compression of the right ventricle causing decreased preload and cardiac output. Gastric decompression was performed, and definitive surgical treatment took place the subsequent day. The postoperative course was uncomplicated.

We report a 12-day-old male who was admitted with vomiting because of an unusual early complication of Marfan's syndrome (MS): a sliding hiatal hernia. Initial ultrasound showed no stomach at its normal position and the chest X-ray presented an intrathoracic gas bubble with the nasogastric tube inside. An upper gastrointestinal contrast study confirmed the complete herniation of the stomach into the thorax. Via an exploratory laparotomy it was carefully reintroduced into the abdomen, following a hiatal reconstruction. A Thal fundoplication and a gastrostomy were also performed to guarantee its fixation. Although characterized by cardiac/aortic abnormalities, MS should be considered in any infant with hiatal/paraesophageal hernia, which should be repaired early to avoid gastric ischemia/volvulus.

Giant paraesophageal hernias can present as an asymptomatic incidentally detected paraesophageal hernia to an emergent gastric volvulus with concern for ischemia. In the acute setting, the preoperative evaluation aims to determine the extent of complications from gastric volvulus. In the elective setting, preoperative testing defines the gastroesophageal anatomy and function to select the optimal operation. Through thoughtful preoperative evaluation, the best operative approach can be tailored to each patient.
