    Author: Ahmad M, Abbas S, Asghar MI.
    Journal: J Coll Physicians Surg Pak; 2003 Nov; 13(11):637-9. PubMed ID: 14700490.
    Abstract:
    OBJECTIVE: To determine the outcome of colorectal surgery without mechanical bowel preparation. DESIGN: A descriptive, analytical and observational study. PLACE AND DURATION OF STUDY: Combined Military Hospital, Kharian and Pano Aqil, from September 1998 to April 2003. SUBJECTS AND METHODS: Forty-seven patients underwent debridement/resection and repair/primary anastomosis of colon and upper rectum without bowel preparation. Of these, 16 patients were operated in emergency. The anastomosis was carried out with polyglactin (vicryl) interrupted, full thickness single layer and no patient had defunctioning colostomy. Third generation cephalosporin, cefotaxime or ceftazidime and metronidazole were given perioperatively, repeated during surgery if lasted for more than 2 hours and continued for 3-5 days postoperatively. RESULTS: Anastomoses were ileocolic in 29.7%, colicocolic in 61.7% and colorectal in 14.8% cases. Anastomotic failure was seen in 4.2% and wound infection in 8.5% cases. There was one mortality (2.1%) due to unrelated cause. CONCLUSION: Mechanical bowel preparation is not necessary for safe colorectal surgery.
