Abstract
Background
The deep inferior epigastric perforator flap (DIEP) has gained widespread popularity in autologous breast reconstruction due to its natural aesthetic results and muscle-sparing design. However, donor site results regarding aesthetic outcome are often less favorable. Despite several studies on surgical technique and improvements of flap harvest, only a small number of studies addressing donor site aesthetic exist.
Methods
A systematic review was performed on donor site aesthetic after DIEP flap harvest according to the PRISMA guidelines. Secondary interests were abdominal wall morbidity and complication rates in general. The following electronic databases were included to identify relevant studies: Medline, Embase, PubMed, Cochrane, and Web of Science.
Results
The search yielded 95 articles for full-text analysis, with only four key studies found on donor site aesthetic specifically. Regarding complication rates, the overall rate of abdominal hernia ranges from 0 to 7.1%. Abdominal bulging occurs in 2.3% to 33%. Besides abdominal wall integrity, wound dehiscence (12-39%), seroma (1-48%), hematoma (1-15%), infections (1-12%), fat necrosis (0-11%) and umbilical necrosis (2-3%) significantly impair donor site aesthetic.
Conclusions
This systematic review reveals that the topic of donor site aesthetic and potential improvement of results has largely been neglected in the past decade. This study provides a thorough evaluation of potential problems that plastic surgeons may encounter and includes recommendations to improve results.
