Economic Consequences of Surgery for Adhesive Small Bowel Obstruction: A Population-Based Study.

BACKGROUND AND AIMS

Most patients develop adhesions after abdominal surgery, some will be hospitalized with small bowel obstruction (SBO), and some also require surgery. The operations and follow-up are expensive, but recent data of costs are scarce. The aim of this study was to describe the direct costs of SBO-surgery and follow-up, in a population-based setting. The association between cost of SBO and peri- and postoperative data was also studied.

METHODS

In a retrospective cohort study, all patients ( = 402) operated for adhesive SBO in Gävleborg and Uppsala counties (2007-2012) were studied. The median follow-up was 8 years. Costs were calculated according to the pricelist of Uppsala University Hospital, Uppsala, Sweden.

RESULTS

Overall total costs were €16.267 million, corresponding to a mean total cost per patient of €40,467 during the studied period. Diffuse adhesions and postoperative complications were associated with increased costs for SBO in a multivariable analysis ( < 0.001). Most costs, about €14 million (85%), arouse in conjunction with the SBO-index surgery period. In-hospital stay was the dominating cost, accounting for 70% of the total costs.

CONCLUSION

Surgery for SBO generates substantial economic burden for healthcare systems. Measures that reduce the incidence of SBO, the frequency of postoperative complication, or the length of stay have the potential to reduce this economic burden. The cost estimates from this study may be valuable for future cost-benefit analyses in intervention studies.
