There is little evidence supporting the use of a water-soluble contrast challenge (WSCC) for conservative management of nonadhesive small bowel obstruction (NASBO). Our objective was to evaluate the prognostic value of the WSCC in a diverse group of patients with NASBO in comparison with patients with adhesive small bowel obstruction (ASBO).Retrospective chart review of patients with ASBO or NASBO who underwent a WSCC during a 4-year time period was performed. The primary study endpoint was any intervention for small bowel obstruction during the initial admission or within 30 days of discharge.A total of 106 patients were included, 53 with ASBO (mean age 64 ± 13 years [SD]; 55% women) and 53 with NASBO (mean age 59 ± 13 years [SD]; 57% women). A higher rate of interventions during admission or within 30 days of discharge was seen in patients with NASBO compared with ASBO (24/53 [45%] vs 12/53 [23%]; p = 0.01), including those with colonic transit times of less than 36 hours (14/41 [34%] vs 5/43 [12%]; p = 0.01). Using multivariate analysis, transit time greater than 36 hours remained an independent predictor of an intervention during admission or within 30 days of discharge (p0.001, odds ratio 19.0), after controlling for the type of small bowel obstruction.A majority of patients with NASBO were successfully managed conservatively during a 30-day period, supporting the use of WSCC in patients with NASBO; however, patients with NASBO had a higher rate of interventions during admission or within 30 days of discharge. |
