| Abstract: | We report 53 patients who developed small bowel obstruction some time after the treatment of a primary malignant tumour. Previous treatment of the primary tumour in these patients had been by abdominal surgery (22 patients) or pelvic radiotherapy (20 patients) but 11 of the patients had not received previous abdominal surgery or radiotherapy. All the patients had a laparotomy in an attempt to relieve the obstruction. Seventeen patients had a cause for the obstruction other than secondary malignancy. This was noted particularly when the patients had had pelvic radiotherapy, when radiation change of the ileum causing obstruction was common. Thirty-six patients had obstruction due to secondary tumour and it was found possible to overcome the obstruction in all but two of these. The operative mortality in the patients with secondary malignancy was 19 per cent, but 15 patients (42 per cent) survived for more than a year and the median survival was 11 months. It is concluded that a policy of aggressive surgical intervention is desirable in patients who develop small bowel obstruction after previous treatment for malignant disease. |
