One hundred thirty-eight consecutive patients undergoing elective colonic resections were treated prospectively and randomly with either a long intestinal (Cantor) tube preoperatively, a nasogastric tube placed intraoperatively, or no gastrointestinal tube at all. Patients were evaluated for length of hospital stay, duration of postoperative ileus, adequacy of intraoperative intestinal decompression, gastric dilatation, and operative complications. No significant difference could be seen in the tubed or no-tube group.
