  • Aim. Surgical site (SSI) infection is a common complication that occurs in the post-operative period because it still has a decisive impact on the morbidity and mortality of patients and the costs associated with therapy and prolongation of hospitalization. In recent years, therefore, several authors have published their experience in the use of negative pressure prevention systems (NPWT) for the management of surgical wounds. Few authors in the literature have discussed the use of NPWT in patients undergoing cytoreductive surgery (CRS) for peritoneal surface malignancies associated with hyperthermic intraperitoneal chemotherapy (HIPEC).

    Patients and methods. Nineteen patients undergoing open surgery, of which 15 underwent CRS+HIPEC operations; in 2 cases the dressing was applied to patients undergoing colon surgery, 1 case after emergency laparotomy for intestinal occlusion in a patient with a BMI of 29 and 1 case after gastric surgery for a tumour. At the and of the surgery, NPWT was placed on the surgical site; the therapy includes a closed and sealed system which maintains a negative pressure between at -125 mmHg on the surgical wound and which remains in place for five days.

    Results. The rationale for using an NPWT is to determine a barrier between the wound and external contamination, reducing wound tension and reducing the formation of seroma and hematoma. Moreover, during the HIPEC, several litres of water are used to wash the patient's abdominal cavity and then the patient is sutured again without the peritoneum, losing the function of protection from external microorganism and also of reabsorbing the intra-abdominal serum. A recent Cochrane collaboration about the application of NPWT demonstrates that it may reduce the rate of SSI compared with SSD, even if there is no sure evidence about the reduction of complications like seromas or dehiscence.

    Conclusion. After the analysis of the preliminary data, we confirm the possibility to start with a randomised clinical trial, as suggested by the literature.
