Clinical Evaluation Of Scar Quality Following The Use Of Prophylactic Negative Pressure Wound Therapy In Obese Women Undergoing Cesarean Delivery A Trial-Based Scar Evaluation

Objective: To evaluate the cosmetic result of using incisional negative-pressure wound therapy (iNPWT) compared with standard postsurgical dressings in obese women undergoing cesarean delivery (CD).Methods: Postcesarean scars were objectively evaluated 6 and 12 months postsurgery by a plastic surgeon using the Manchester Scar Scale and the Stony Brook Scar Evaluation Scale. Subjective scar evaluation and health-related quality of life were assessed using the Patient Scar Assessment Scale and the EQ-5D-5L instrument, respectively. Main outcome measures were the cosmetic and functional outcome of treating a standardized surgical wound with iNPWT compared with standard dressings, changes in scar rating over time, and testing different scar scales for cosmetic evaluation.Results: The study found no difference in long-term cosmetic outcomes between iNPWTand standard dressings. The study demonstrated a statistically significant positive change in scar rating from surgery to 12 months postsurgery. A strong association was found between the scar scales with a high correlation between the objective scar scales (R approximately 0.80) and a moderate correlation between the subjective scale and each objective scale (R approximately 0.50).Conclusions: Prophylactic iNPWT has been found to reduce the risk of surgical site infection following CD. Conversely, this study was not able to detect a difference in the long-term cosmetic result after CD when compared with standard dressings.
