P-014 RISK FACTORS FOR SHORT- AND LONG-TERM COMPLICATIONS FOLLOWING VENTRAL HERNIA REPAIR WITH THE PERITONEAL FLAP TECHNIQUE

Abstract

Abstract Aim The peritoneal flap technique has been introduced for the repair of complex abdominal wall defects. The present study was conducted to determine the association between preoperative risk factors and the incidence of short and long-term complications. Material & Methods Patients undergoing abdominal wall repair between January 2010 and September 2020 were included in the study. Patient files were retrospectively reviewed and the presence of risk-factors and the incidence of postoperative short and long-term complications were recorded. A multivariable logistic regression analysis was used to estimate odds ratio (OR) for postoperative complications. Results 327 patients were included. 48.0% were male. Median body mass index(BMI) was 30.9, 13.8% had diabetes and 23.2% were active smokers. Median defect size was 8 cm2 and median mesh size was 667.5 cm2. Median length of hospital stay was 5 days. 13.1% of patients developed a superficial wound infection, 10.4% seroma and 1.2% skin necrosis. Chronic pain was observed in 4.6% and recurrence in 2.4%. The regression analysis demonstrated a stepwise increase in OR for short and long-term complications. This risk was increased by 10% per unit BMI (P<0.01). Smoking and hernial defect size contributed only to a minor extent to the risk of postoperative complications. Conclusion The peritoneal flap method is a safe procedure associated with a low risk of recurrence. The risk of complications is associated with BMI whereas smoking and hernial defect size only contributes to a minor extent.
