Management of Post-VATS Pneumoperitoneum After Diaphragmatic Repair

Initial Assessment and Clinical Monitoring

In a patient with pneumoperitoneum on chest X-ray following VATS decortication with primary diaphragmatic repair, conservative management with close clinical observation is the appropriate initial approach, as pneumoperitoneum is an expected finding after diaphragmatic manipulation and does not require surgical re-exploration in the absence of peritonitis, according to the European Respiratory Journal 1, 2
Serial abdominal examinations should be performed every 4-6 hours for the first 48 hours post-operatively to detect any evolving peritonitis, as recommended by the Praxis Medical Insights 3
Laboratory monitoring, including serial white blood cell counts and lactate levels, should be checked to detect rising trends that suggest intra-abdominal pathology requiring intervention, as recommended by the Praxis Medical Insights 3

Continue chest tube drainage on water seal or low suction (-20 cm H2O) to evacuate residual air and fluid from the thoracic cavity, as recommended by the Thorax journal and Praxis Medical Insights 3, 4
Antibiotic coverage with prophylactic antibiotics covering skin flora (cefazolin 1-2g IV every 8 hours) should be continued for 24-48 hours post-operatively, as recommended by the Praxis Medical Insights 3

Sepsis without source, characterized by fever, leukocytosis, and rising lactate without identified thoracic infection, is an indication for surgical re-exploration, as recommended by the Praxis Medical Insights 3

Pleural space infection should be treated with vancomycin 15-20 mg/kg IV every 8-12 hours PLUS piperacillin-tazobactam 4.5g IV every 6 hours, as recommended by the Praxis Medical Insights 3
Persistent air leak beyond 5-7 days may require consideration of intrapleural sealants or surgical revision, as recommended by the Thorax journal 4
Retained hemothorax may require consideration of intrapleural fibrinolytics (TPA 10mg plus DNase 5mg twice daily for 3 days) before repeat VATS, as recommended by the Praxis Medical Insights 3

Delaying conversion to open thoracotomy if VATS visualization was inadequate may result in a 20% risk of incomplete decortication requiring early reoperation, as recommended by the Praxis Medical Insights 5
Failing to obtain pleural fluid analysis before assuming abdominal source of symptoms such as fever, tachycardia, or leukocytosis may lead to misdiagnosis, as recommended by the Praxis Medical Insights 3
