One of the modern laparostomy methods is closure of the abdominal cavity using VAC. Method principle is the active suction which is continual and it drains effusion from the abdominal cavity and thus reduces intraabdominal bacterial contamination and also supports blood circulation and vitality of the wound edges. It is a method which fulfills advantages of laparotomy including expansion of the abdominal cavity, effusion drainage quality of which can be controlled; it is a closed system in which there is no risk of external contamination as in case of common laparostomy. Use of VAC method was verified in various wound types with copious secretion (sternotomy, diabetic foot or fascitis). Method of VAC laparostomy was described; however prospective and randomized use in peritonitis has not bee evaluated yet.
