Systemic prophylaxis with doxycycline in surgery of the colon and rectum.
A prospective double-blind study on the effects of doxycycline as a prophylactic antimicrobial in elective colonic surgery is presented. One hundred-eighteen patients were evaluated. Fifty-eight were treated and 60 were controls. Two hundred milligrams, doxycycline or placebo (two capsules) were given orally four to six hours prior to surgery and 100 mg or placebo (one capsule) for five days postoperatively. Doxycycline levels in serum and tissues were determined and related to the MICvalues of the contaminants of the operative field. A significantly lower incidence of abdominal wound sepsis, intra-abdominal complications, and septicemia was recorded in the doxycycline group compared to the control group, 12.1 and 45% respectively. The prophylactic effect was most pronounced in patients with a negative wound culture upon closure. Macroscopical peritoneal contamination was associated with less severe consequencies in the doxycycline group. Infections in the perineal field, 3/15 vs 8/17, appeared alone in the doxycycline group, whereas they were combined with abdominal sepsis in 6/8 among the controls. Treatment also reduced the incidence of repeat laparotomy due to septic complications, 0 vs 8. Thus systemic per and postoperative prophylaxis with doxycycline significantly reduced both the incidence and the severity of postoperative sepsis in potentially contaminated elective colorectal surgery without any adverse reactions.
