About

The ORALEV Study found that preoperative oral antibiotics can reduce the incidence of surgical site infections after colonic resection, compared with no preparation.

The role of mechanical bowel preparation in patients needing colonic surgery is yet to be elucidated.

No randomised controlled trials have assessed the impact of mechanical bowel preparation combined with oral antibiotics on the incidence of surgical site infections after colonic surgery, compared with oral antibiotics only.

Full description

International, multicentre, pragmatic, parallel-group, randomised controlled trial.

Routine antibiotics for the intravenous and oral prophylaxis of colorectal surgery will be used.

Experimental group: Patients undergoing elective colonic surgery that involves colonic resection.

The antibiotic prophylaxis in this group will be composed of:

An oral antibiotic pattern of ciprofloxacin (750mg / 12h, 2 doses) and metronidazole (250mg / 8h, 3 doses) the day before surgery, plus mechanical bowel preparation with Sodium picosulfate, light magnesium oxide, and anhydrous citric acid (10 mg - 3.5 g - 10.97 g per dose/ 2 doses the day before surgery) + An intravenous antibiotics pattern of cefuroxime 1,5 g and metronidazole 1 g at anesthetic induction.

Control group: Patients undergoing elective colonic surgery that involves colonic resection.

The antibiotic prophylaxis in this group will be composed of:

An oral antibiotic pattern of ciprofloxacin (750mg / 12h, 2 doses) and metronidazole (250mg / 8h, 3 doses)

  • An intravenous antibiotic pattern of cefuroxime 1,5 g and metronidazole 1 gr at anesthetic induction.

In both groups a second intravenous dose of cefuroxime (750mg) will be administered if the intraoperative time prolongs for more than three hours or if there is an intraoperative bleeding over 1000cc.

There will not be a placebo treatment. Subject compliance will be evaluated according to the usual practice in surgical care field
