BACKGROUND: Recent studies show that early operative intervention in patients who fail non-operative management of adhesive small bowel obstruction (ASBO) is associated with improved outcomes. The purpose of this study was to determine the trend in practice pattern and outcomes of patients with ASBO in the United States.
METHODS: Data from the National Inpatient Sample data (2003-2013) were extracted for analysis, and included patients (age ≥18 years) who were discharged with primary diagnosis codes consistent with ASBO. We analyzed the data to examine changes in mortality and hospital length of stay (HLOS) in addition to any trends in rate and timing of operative interventions.
RESULTS: During the study period, 1,930,289 patients were identified with the diagnosis of ASBO. Over the course of the study period, the rate of operative intervention declined (46.10 to 42.07%, p=0.003), and the timing between admission and operative intervention was significantly shortened (3.09 to 2.49 days, p<0.001). Additionally, in-hospital mortality rate decreased significantly (5.29 to 3.77%, p<0.001). In the multiple logistic regression analysis, the relative risk of mortality decreased by 5.6% per year (OR: 0.944, 95% CI: 0.937-0.951, p<0.001). HLOS decreased from 10.39 days to 9.06 days (P<0.001).
CONCLUSION: Over the last decade, fewer patients with ASBO were managed operatively, whereas those requiring an operation underwent one earlier in their hospitalization. Although further studies are warranted, our results suggest that recent changes in practice pattern may have contributed to improved outcomes.
