A prospective randomized trial of routine postoperative nasogastric decompression in patients with bowel anastomosis.

Until relatively recently, the nasogastric (NG) tube has been used routinely for decompression in the patient with small- or large-bowel anastomosis. To determine if routine postoperative NG decompression benefited such patients, 102 patients were randomized prospectively to either NG decompression or no-NG tube. Excluded were patients with chronic bowel obstruction, peritonitis, gross fecal contamination or spillage, and previous abdominal or pelvic irradiation. There were 52 patients in the no-NG group and 50 in the NG group. Patients in the no-NG group had earlier bowel sounds, return of flatus, oral intake and first bowel movement. Four patients (8%) in the no-NG group, compared with one patient (2%) in the NG group, required subsequent decompression. Length of hospital stay was significantly (p < 0.001) shorter in the no-NG group. There were no significant differences in the presence of atelectasis, postoperative fever, wound infections and anastomotic leaks between the two groups. The authors conclude that routine nasogastric decompression is not warranted after elective surgery involving small- or large-bowel anastomosis.
