Strangulation of chronic transdiaphragmatic intercostal hernia.

Transdiaphragmatic intercostal hernia (TIH) caused by violent coughing is a rare clinical diagnosis. Most patients diagnosed with TIH have a chronic condition consisting of a hernia that can be reduced completely by surgical intervention. Our patient presented with acute abdomen resulting from mechanical bowel obstruction secondary to an incarcerated hernia. Acute TIH presents a diagnostic challenge because of its rarity and lack of specific signs or symptoms in the differential diagnosis of acute abdomen. We recommend performing diagnostic computed tomography (CT) early if there is suspicion of TIH. Surgical intervention is always needed. Surgical intervention was complicated in this case, necessitating both transthoracic and abdominal exposure to resect the ischemic bowel segment. Nonetheless, the patient recovered uneventfully.
