The author describes the technique of closure of surgical wounds by continuous suture. It is a vertical mattress suture, as described by Donatti-Mc Millen, which is made continuously along the whole wound. It may involve either one layer, depending on the depth of the wound, or it can be used after the usual treatment of the subcutaneous layer. For suture monophil fibre with atraumatic threading is optimal but any other material can be used for suture. The advantage is the simple and rapid character of the procedure, adequate haemostasis and perfect adaptation of the margins of the wound. A balanced tension of the fibre in the whole wound reduces the risk of ischaemisation of a single stitch. The stitch can be readily removed, and if properly done, the cosmetic effect is satisfactory. The economy of material is not negligible either. The authors have used it as a matter of routine since 1984.
