Abdominal wall reconstruction for large incisional hernia restores expiratory lung function

Area of Science:

• Surgery
• Pulmonology
• Reconstructive surgery

Background:

• Respiratory complications are common after abdominal wall reconstruction for large incisional hernias.
• Long-term effects on respiratory function and daily living are unknown.
• Hypothesis: reconstruction does not improve long-term pulmonary function or quality of life.

Purpose of the Study:

• To evaluate the long-term impact of abdominal wall reconstruction on pulmonary function and respiratory quality of life.
• To compare outcomes between patients undergoing reconstruction and those with intact abdominal walls.

Main Methods:

• 18 patients with large incisional hernias (>10 cm defect) underwent reconstruction.
• Compared with 18 patients undergoing colorectal resection with intact abdominal walls.
• Pulmonary function tests and quality of life questionnaires assessed pre- and 1-year postoperatively.

Main Results:

• Abdominal wall reconstruction group showed improved percent predicted peak expiratory flow and maximal expiratory mouth pressure at 1 year.
• Other lung function measurements and respiratory quality of life remained unchanged.
• Greater improvement in peak expiratory flow observed in the reconstruction group compared to the colorectal resection group.

Conclusions:

• Abdominal wall reconstruction for large incisional hernias leads to improved long-term expiratory lung function.
• Respiratory quality of life is not significantly altered post-reconstruction.
