Summary
Major abdominal surgery patients face a 1% risk of wound dehiscence. Key risk factors include age over 65, wound infection, and hemodynamic instability, with increasing risk factors correlating to higher mortality.
Area of Science:
- General Surgery
- Surgical Complications
- Wound Healing
Background:
- Abdominal fascial wound dehiscence is a serious complication after major abdominal surgery.
- Identifying risk factors is crucial for prevention and management.
Purpose of the Study:
- To identify independent local and systemic risk factors for abdominal fascial wound dehiscence.
- To assess the correlation between risk factors and patient mortality.
Main Methods:
- Retrospective analysis of 31 cases of abdominal fascial wound dehiscence in 2,761 patients.
- Comparison with a control group of 38 patients without dehiscence.
- Multivariate analysis to determine independent risk factors (p < 0.05).
Main Results:
- Significant risk factors identified: age > 65, wound infection, pulmonary disease, hemodynamic instability, ostomies, hypoproteinemia, systemic infection, obesity, uremia, hyperalimentation, malignancy, ascites, steroid use, and hypertension.
- Patients with ≥5 risk factors had a 30% dehiscence rate; those with >8 risk factors had 100% dehiscence.
- Overall mortality was 29%, directly related to the number of risk factors; >10 risk factors resulted in 100% mortality.
Conclusions:
- Several local and systemic factors significantly increase the risk of abdominal wound dehiscence.
- The number of co-existing risk factors strongly predicts both dehiscence occurrence and patient mortality.
- Risk stratification based on these factors can aid in surgical planning and patient management.
