Risk Factor Assessment for the Development of Surgical Site Infection in Patients Undergoing Colorectal Cancer Surgery

Surgical site infection (SSI) is a common complication following colorectal cancer (CRC) surgery and represents a significant cause of slower postoperative recovery and prolonged hospital stay. Therefore, this study aims to determine which risk factors contribute most to SSI development, and to assess the effectiveness of SENIC and NNIS scores in evaluating SSI risk after CRC surgery. This retrospective observational cohort study is conducted at the Oncology Institute of Vojvodina. Sixty-two patients are included, undergoing elective CRC surgery between 03.06.2024. and 31.10.2024. Data are collected from the information system and medical records, including demographic characteristics, presence of SSI, comorbidities, data regarding neoadjuvant oncological therapy, preoperative laboratory findings, type and duration of surgical intervention, perioperative complications, and SENIC and NNIS scores are calculated. The study is supported by a Collegium Talentum scholarship from the Ministry of Human Capacities (Hungarian Government), for the 2024/2025 academic year (recipient Nora Mihalek, MD).
