[Preventive preoperative antibiotic therapy in elective colon surgery. A controlled prospective randomized study]

Abstract

Antibiotic prophylaxis in elective colonic surgery is of established value and most authors have proposed an association of at least two drugs. We have compared the efficacy of classical prophylaxis (clindamycin and gentamicin, C + G) with that of the single drug cefoxitin (Ce). 101 consecutive patients were covered; 22 had to be excluded and 7 withdrawn after randomization; 72 cases were left for final analysis (C + G 35; Ce 37). Five C + G (14.2%) and 4 Ce cases (10.8%) developed septic complications, possibly caused by opening of the colon (wound infection, anastomotic failure, colocutaneous fistula): this difference is not statistically significant. Episodes of sepsis, urinary tract infection and pneumonia were similar in both groups. Although the number of patients included is relatively small, we conclude that prophylaxis with Ce alone appears to be as effective as double drug prophylaxis with C + G.
