[Adhesive small bowel occlusion: a clinical and therapeutic study of 163 consecutive patients]

The aim of this retrospective study is to evaluate the immediate and late outcomes of the surgical and conservative treatment of adhesive small bowel obstruction. A series of 163 consecutive patients affected by adhesive occlusion were analysed. 63 patients were submitted to emergency surgery and 100 to conservative treatment; 15 of these ones were operated on because they did not improve or deteriorated. The in-hospital mortality and morbidity, the length of the ileus, the time required for the operatori, the length of the recovery, and the late results after a median follow-up of 3.6 years (range: 1-6 years) are reported. The overall mortality was 3.26% and there was no significant difference (p = 0.764) between the treatment modalities. The patients submitted to conservative therapy had a lower morbidity, shorter length of the ileus and shorter hospital stay and a better outcome at follow-up. In the surgical group, the patients submitted to emergency surgery had a lower mortality, a shorter ileus and shorter hospital stay than the patients submitted to delayed surgery. Conservative treatment of adhesive occlusions should be opted for when the indications are correct (no intestinal ischaemia, no occlusion by a bridle). In doubtfui cases, the patient should be submitted to emergency surgery to avoid the risks of surgical delay.
