- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None

Study Arms:
- ornidazole (Type: EXPERIMENTAL): oral antibiotic prophylaxis using ornidazole, which has a spectrum of activity extended to most anaerobic bacteria and whose pharmacokinetic profile allows a single administration the day before surgery, in addition to intravenous antibiotic prophylaxis could be more effective than intravenous antibiotic prophylaxis alone using cephalosporin in reducing the incidence of SSI after elective colorectal surgery. Given the number of patients operated of colorectal surgery each year, the study is of significant clinical importance
- placebo (Type: PLACEBO_COMPARATOR): oral antibiotic prophylaxis using ornidazole, which has a spectrum of activity extended to most anaerobic bacteria and whose pharmacokinetic profile allows a single administration the day before surgery, in addition to intravenous antibiotic prophylaxis could be more effective than intravenous antibiotic prophylaxis alone using cephalosporin in reducing the incidence of SSI after elective colorectal surgery. Given the number of patients operated of colorectal surgery each year, the study is of significant clinical importance
