title: Growth factors and gastrointestinal anastomotic healing.
abstract: BACKGROUND
  Failure of anastomotic healing in the gastrointestinal tract is a major source of surgery-related morbidity, repeated surgical procedures, and impaired quality of life. Growth factors have been shown to be involved in healing processes in various tissues including the gastrointestinal tract. This opens the perspective to use growth factors therapeutically to support impaired anastomotic healing. The aim of the present study was to review the particular role of several growth factors in different phases of anastomotic healing, experimental approaches of growth factor application, and to discuss possibilities and limitations of growth factor-directed interventions in gastrointestinal surgery.
  
  
  METHODS
  A PubMed search was performed to examine the potential role of fibroblast growth factor, epidermal growth factor, heparin binding EGF-like growth factor, transforming growth factor β, insulin-like growth factor I, vascular endothelial growth factor, and platelet-derived growth factor during anastomotic healing.
  
  
  RESULTS
  Growth factors show beneficial effects on a broad range of cell types and regulate various processes during all phases of tissue healing. Despite extensive research in the field of growth factors, additional evidence is needed before translating into a clinical setting.
  
  
  CONCLUSIONS
  Future research should focus on adequate sustained but limited drug delivery. Undesired side effects, such as formation of strictures, development of peritoneal adhesions, and potential induction of malignancies, have to be reflected. Although growth factor application is currently far from clinical routine in gastrointestinal surgery, it might find application in selected patients at risk for impaired anastomotic healing, such as patients with long-time steroid therapy, immunosuppressives, inflammatory disorders, sepsis, hemodynamic shock, malnutrition, or neoadjuvant radiochemotherapy.
