Diaphragmatic hernias result from a defect in the diaphragm that allows abdominal contents to herniate into the thoracic cavity. The most common cause is acute trauma, particularly blunt force trauma, more than penetrating trauma. Congenital causes are the second most common cause. Such as Bochdalek and Morgagni hernias. There are other types and the most uncommon is a spontaneous diaphragmatic hernias (SDH). This paper presents a novel case of SDH, leading to gastric fundus protrusion and incarceration, resulting in abscess formation. The patient’s medical history did not suggest trauma or congenital anomalies, making this case an acquired SDH, with fewer than 40 documented occurrences. Diagnosis is often delayed due to the overlap of symptoms with other conditions, and SDH frequently presents with nonspecific gastrointestinal or respiratory symptoms. Imaging, particularly CT, is crucial for diagnosis. The patient underwent successful repair using a transabdominal robotic approach with the Da Vinci Xi system, marking the first documented case of SDH repaired exclusively with robotic techniques. This case highlights the importance of considering SDH in patients with unexplained thoracoabdominal pain, particularly in the absence of trauma, and demonstrates the efficacy of robotic surgery in minimizing complications and reducing morbidity in such cases.
