To investigate the clinical efficacy and application value of preoperative progressive pneumoperitoneum treatment for patients with complex abdominal wall defects.

Nine patients with complex abdominal wall defects were conducted preoperative progressive pneumoperito-neum. Retrospective analysis of the clinical data and therapeutic effect of these patients from January 2013 to June 2015 were carried out. Patients were treated with progressive pneumoperitoneum for 2-3 weeks. The abdominal wall defect repair operations were performed after the expansion of the abdominal cavity and the abdominal wall compliance.

All the patients successfully underwent the preopera-tive progressive pneumoperitoneum. No patients endured intolerant pneumoperitoneum conditions and se-vere complications related to pneumoperitoneum. After the operation, there was no abdominal compart-ment syndrome and cardiac or pulmonary function disorder when the hernia content came back to the ab-dominal cavity.

Preoperative progressive pneumoperitoneum therapy is a simple, safe and reliable minimally invasive method, providing a new choice of perioperative preparations for patients with complex abdominal wall defects.
