Abstract
Objective: To report a case of Bochdalek hernia in adults and discuss their prevalence and clinical manifestations. Case report: A 37-year-old male patient was admitted to the emergency room complaining of diffuse abdominal pain and continued for five days, associated with dyspnoea, nausea, fecaloid vomiting, inappetence, flatus and stool elimination stopping. The picture was refractory to the use of anti-acidosis and antacids. Deny history of traumas. On examination, distended abdomen, increased hydroaic noise and painful palpation. Tomography was performed, with signs suggestive of acute obstructive abdomen. She underwent emergency exploratory laparotomy and identified hernia sac in the left post-lateral region of the diaphragm with colon strangulation. Final considerations: Bochdalek hernia is commonly seen in neonates. In adults, its occurrence is rare, predominating on the right and in women. It may present with non-specific gastrointestinal and respiratory symptoms and acute incarceration or perforation. There is, therefore, the need for clinical reasoning for its diagnosis associated with imaging techniques.
