A new silver dressing, StopBac, used in the prevention of surgical site infections.

Ideal dressings of surgical wounds should provide moist, semi-permeable, and antiseptic environments for optimal wound healing. To maximise patient comfort, surgical dressings must be hypoallergenic, not restrict movement, and allow patients to manage their personal hygiene. From the aspect of health care personnel, dressings should enable visual monitoring of the wound without the need for removing them, thus reducing the number of dressing changes. The active antimicrobial effect of silver cations has been demonstrated by many studies. StopBac is a unique surgical dressing based on the sol-gel process. Silver cations are bound in a colloidal solution in an organic-inorganic hybrid organosilicate oligomer. This gel is deposited on a pad using spray atomisation. The result is a polymer nanolayer matrix with prolonged and controlled release of silver ions. This pad forms part of a waterproof hypoallergenic transparent adhesive bandage. The goal of this study was to prospectively evaluate the ability of StopBac to prevent surgical site infections (SSIs) in patients after abdominal surgery. The secondary goal was to compare costs and determine the properties of this new material. A total of 32 patients were included in the study. The patients were followed up until their surgical wounds healed completely. An SSI occurred only in one patient.

Oncosurgery in older patients.

Population aging is one of the most significant health problems of the 21st century and has led to an increased need for surgery in elderly patients. Only chronological age should not be decisive when indicating patients for elective procedures. Other objective findings should be taken into account too. The complex geriatric examination is an optimized, detailed and accurately defined method, which leads to better postoperative outcomes in elderly patients. In everyday practice it is sufficient to evaluate the mental, physical and nutritional state of the patient. The goal of our study was to evaluate the perioperative morbidity and mortality of elderly patients undergoing hepatopancreatobiliary procedures. In our retrospective study we evaluated prospectively collected data of patients who underwent surgical procedures between 2015 and March 2019. In total 245 patients underwent pancreatic procedures and 156 underwent hepatic procedures. Morbidity and mortality were evaluated in the first 75 postoperative days and classified according the Clavien-Dindo classification. Our results show that when surgical procedures are correctly indicated in elderly patients, acceptable postoperative morbidity and mortality can be achieved. Since the year 2018 we have been actively using prerehabilitation in our center and it has led to improved postoperative outcomes in elderly and high-risk patients.
