Abstract
Over a two-year period (1982–1984) polypropylene (Marlex) mesh was used without closing the abdominal wound in 21 patients judged clinically likely to require further abdominal exploration. A total of 43 meshes were implanted. All 21 patients had more than one major laparotomy, median 3 laparotomies (range 2–7) for drainage of pus (76 per cent) and/or intestinal leakage (67 per cent). Definitive abdominal wound closure after removal of polypropylene mesh was either by delayed primary suturing (33 per cent) or consisted of split skin grafting on the granulating wound (24 per cent). Three wounds were left to granulate without skin grafting (14 per cent). Mortality in this group of patients was 29 per cent and no complications resulted directly from implantation of polypropylene mesh. Polypropylene mesh closure of the abdominal wall not only provides simple and rapid access to the abdomen but also allows free drainage and daily inspection for the development of fistulae or the seepage of pus which are indications for further exploration. In that the clinical outcome is relatively favourable in this group of critically ill surgical patients who required multiple laparotomies within a short interval, it is suggested that mesh closure of the abdominal wound is indicated whenever abdominal reentry is judged probable or rational.
