Abstract (original English)

Cesarean section results in scarring, which usually leads to adhesion between the subcutaneous fat and the abdominal wall muscle. The present study aimed to evaluate the therapeutic effect of autologous fat grafting on scar adhesion to the abdominal wall after cesarean section. Thirty-six patients with scar adhesion to the abdominal wall after cesarean section were recruited and treated between October 2013 and December 2015. The adhesion between the subcutaneous fat and the abdominal wall muscle was carefully separated through a small incision in the original scar to form multiple subcutaneous tunnels. Aspirated fat was injected into the scar lesion and subcutaneous tunnels, and the wound was then sutured. The clinical outcome was evaluated by comparing the pretreatment and 1-year posttreatment photographs and Patient and Observer Scar Assessment Scale (POSAS) scores. All patients had a marked improvement in the appearance, texture, and depression of the scar during 12 months of follow-up. The 1-year posttreatment POSAS scores for the color, pain, pruritus, hardness, fullness, mobility, and appearance of the scar were significantly decreased compared with the pretreatment scores. Hematoxylin-eosin staining revealed adipocyte-like cells in treated scar tissue specimens obtained 1 year after treatment. None of the patients reported severe adverse reactions.
