title: Correction of skin contour defects in leaking stomas by filler injection: a novel approach for a difficult clinical problem.
abstract: BACKGROUND
  Stomal leaks can be associated with significant social, psychological and physical morbidity for ostomy patients. Poor fitting of the stoma appliance due to irregularities of skin contours is one cause of stoma leaks which commonly result in secondary irritant dermatitis prompting presentation to a dermatologist. In addition to skin-directed topical therapy and review of stoma appliances, correction of contour defects with intradermal injections of filler materials is one possible treatment to improve adhesion and reduce leaks.
  
  
  METHODS
  We report eight cases of ostomy patients, who presented with stoma leaks and associated dermatitis, who were treated with intradermal injections of the porcine collagen (Permacol™) or subcutaneous injections of polyacrylamide hydrogel (Aquamid Reconstruction™) for correction of skin contour defects. Resolution or improvement of symptoms was achieved for five patients, and no complications were noted as a result of treatment.
  
  
  CONCLUSIONS
  This report represents the largest series of ostomy patients treated for correction of peristomal skin contour defects with injection therapy. Treatment was well tolerated and performed in the outpatient setting under local anesthetic. Attempted correction of peristomal skin contour defects using injection of filler materials represents a potential alternative to surgical intervention and can result in significant benefits for the patient.
