Long-term follow-up and cost analysis following surgery for small bowel obstruction caused by intra-abdominal adhesions

Abstract

This study examined the natural course of patients following surgery for small bowel obstruction (SBO) caused by abdominal adhesions. In addition, a cost analysis was performed. A retrospective analysis was undertaken of 102 patients who underwent surgery between 1987 and 1992 for intestinal obstruction due to abdominal adhesions. Median follow-up was 14 years. The 102 patients experienced 273 episodes of intestinal obstruction after the index operation, of which 237 involved inpatient readmissions; 47.3 per cent of the episodes resulted in further surgery. Single band adhesions were more common in patients with no previous abdominal surgery (P < 0.001). Some 52.0 per cent of the patients had undergone only one operation for SBO. A mean of 2.7 episodes per patient occurred after the index operation. The cost of adhesion-related problems in this study was 1,588,594 euros or 6702 euros per inpatient episode. The readmission rate in a selected cohort of patients with proven intra-abdominal adhesions was higher than reported previously. The annual cost of adhesion-related problems in Sweden was estimated as 39.9-59.5 million euros, and the cost of inpatient readmissions was almost equal to that for gastric cancer.
