Inclusion criteria
Inclusion criteria: 1.Aged >= 18 years old, no gender restriction; 2.Undergoing elective abdominal surgery (e.g., cholecystectomy, appendectomy, gastrointestinal anastomosis, etc.); 3.No preoperative skin breakage, skin infection or systemic infectious symptoms (such as fever and elevated white blood cell count), to avoid confounding interference of preoperative infection status on the judgment of postoperative surgical site infection; 4.Complete medical records available, including documentation of skin preparation methods, surgical wound classification, administration of prophylactic antibiotics, attending surgeon information, and follow-up records of postoperative wound healing; 5.Postoperative follow-up duration >= 30 days. Explanation: Surgical site infections mostly occur within 10 days or even 30 days after surgery. Prolonged follow-up duration is adopted to reduce missed diagnosis of delayed infection.
Exclusion criteria
Exclusion criteria: 1.Emergency abdominal surgery (e.g., traumatic intestinal rupture, acute obstructive suppurative cholangitis, etc.), which is characterized by short preoperative preparation time and numerous confounding factors. 2.Patients complicated with immunocompromising diseases (e.g., malignant tumors, acquired immunodeficiency syndrome (AIDS), long-term glucocorticoid administration). Such patients have an inherently markedly elevated infection risk, which may mask the difference in efficacy of different skin preparation protocols. 3.Surgical duration > 3 hours; prolonged operative time independently increases infection risk, hence these cases shall be excluded. 4.Patients transferred to the intensive care unit (ICU) postoperatively or discharged early due to other comorbidities, making complete follow-up of incision outcomes unachievable. 5.Pre-existing intra-abdominal infection before surgery (e.g., acute suppurative appendicitis with perforation). Preoperative infectious status directly elevates the risk of postoperative surgical site infection (SSI) and distorts the correlation between study variables.
