Methods In a prospective case control study of 16 patients, the healing rate of secondary suturing of subcutaneous wound infections after median laparotomy wounds for colorectal surgery was investigated, whereby the wounds had previously been conditioned using negative pressure wound therapy (NPWT) with polyhexamethylene biguanide (PHMB) gauze. Results After opening the infected wound the average wound volume was 203聽ml. A d茅bridement of the wounds was carried out to remove necrotic and sloughed tissue then the first NPWT dressing was applied. The NPWT with PHMB gauze could be changed on average every 3 days at the bedside which was possible because the pain level during each dressing change was recorded as an average of 1 on the visual analog scale (VAS). After an average of 3 NPWT dressing changes, the wounds showed no signs of infection and secondary suturing was carried out at the bedside using local anesthesia. For the first 7 patients, subcutaneously placed capillary drainage without suction was used in the wounds (group 1). As the healing rate was low (29鈥?) subcutaneously placed round channel drainage under suction were used for the next 9 patients (group 2) and the healing rate was 89鈥? after secondary suture. The average costs for NPWT treatment including labor costs were calculated as 322.20聽EUR per patient. Conclusion All procedures could be performed at the bedside and all patients were satisfied with the treatment and results. The NPWT therapy with PHMB gauze provides an economic method for lowering the total treatment time and costs as well as unnecessary usage of operating theaters.
