Investigation of the Effectiveness of Prophylactic NPWT (ciNPWT) in High-risk Diabetic Patients With Acute Laparotomy Wounds

Inclusion Criteria:a (all criteria must apply simultaneously): * Age ≥18 years, * Undergoing urgent abdominal surgery, * Diagnosis of diabetes mellitus either already present or newly diagnosed at admission * High SSI risk. We consider a patient to be at high SSI risk if the operating surgeon categorizes the patient as high risk, and the patient is classified in the III-IV cleanliness category with an open abdominal surgical procedure (laparotomy). "High SSI risk" may also be assessed individually based on existing severe risk factors or using an SSI risk calculator (patients with a normal laparotomy SSI risk more than 3 times the baseline are eligible). Exclusion Criteria: (any of the following): * Pregnancy, * Disseminated cancer (irresectable distant metastasis, peritoneal carcinomatosis), * Life expectancy of less than 30 days, * Refusal to participate in the study.
