Summary
Older age and higher BMI increase incisional hernia risk after pancreatic surgery. While weight loss optimization is ideal, it
Area of Science:
- Surgical outcomes
- Gastroenterology
- Hernia research
Background:
- Incisional hernias (IH) are a complex complication post-pancreatic surgery.
- Risk factors are multifactorial, involving patient and surgical elements.
Purpose of the Study:
- To systematically review and meta-analyze risk factors for IH development after pancreatic surgery.
- Identify key patient and surgical variables associated with IH incidence.
Main Methods:
- Systematic search of PubMed, Cochrane, and EMBASE databases.
- Inclusion of observational studies and RCTs with patients >18 years.
- Meta-analysis of incidence and risk factors including age, BMI, diabetes, smoking, and SSI.
Main Results:
- Pooled incidence of IH was 12.5% (95% CI 7.1, 20.9).
- Older age (MD 2.7 years) and higher BMI (MD 1.8) significantly increased IH risk.
- Gender, smoking, diabetes, and SSI were not significant risk factors.
Conclusions:
- Older age and higher BMI are significant risk factors for incisional hernias post-pancreatic surgery.
- Preoperative weight optimization may reduce IH morbidity when feasible.
- Surgeons should consider patient age and BMI in risk assessment for IH.
