Benign pneumoperitoneum following median sternotomy incision

Area of Science:

• Thoracic Surgery
• Abdominal Surgery
• Medical Imaging

Background:

• Median sternotomy and cardiac surgery involve close proximity to the diaphragm and peritoneal cavity.
• Inadvertent opening of the peritoneal cavity can occur during these procedures.

Observation:

• A benign pneumoperitoneum, characterized by air in the abdominal cavity, may be observed post-cardiac surgery.
• This is often a result of surgical technique rather than intra-abdominal pathology.

Findings:

• The presence of pneumoperitoneum following median sternotomy is typically benign.
• Distinguishing this from pneumoperitoneum secondary to intra-abdominal issues or ventilator-induced air dissection is crucial.

Implications:

• Recognizing benign post-sternotomy pneumoperitoneum avoids unnecessary investigations and interventions.
• Accurate diagnosis ensures appropriate patient management and prevents misattribution of symptoms.
