A prospective, randomized trial of short versus long tubes in adhesive small-bowel obstruction

: Many cases of acute adhesive small-bowel obstruction (SBO) can be successfully treated with intestinal tube decompression. There is considerable controversy, however, regarding whether a short nasogastric tube (NGT) or a long nasointestinal tube (LT) is the best method of intestinal tube decompression. : A prospective, randomized trial was conducted to compare NGT and LT decompression with respect to the success of nonoperative treatment and morbidity of surgical intervention in 55 patients with acute adhesive SBO. : Twenty-eight patients were managed with NGT and 27 with LT. There were 44 cases of partial SBO (23 NGT, 21 LT) and 11 cases of complete SBO (5 NGT, 6 LT). Twenty-one patients ultimately required operation, including 13 managed with NGT (46%) and 8 with LT (30%) (P = 0.16). The mean period between admission and operation was 60 hours in the NGT group versus 65 hours in the LT group. At operation, 3 patients in the NGT group had ischemic bowel that required resection. Postoperative complications occurred in 23% of patients treated with NGT versus 38% of patients treated with LT (P = 0.89). Postoperative ileus averaged 6.1 days for NGT patients versus 4.6 days for LT patients (P = 0.44). There were no deaths. : Patients with adhesive SBO can safely be given a trial of tube decompression upon hospital admission. There was no advantage of one type of tube over the other in patients with adhesive SBO.
