Bedside Small Bowel Follow-Through: The Role in the Management of Adhesive Small Bowel Obstruction.

BACKGROUND

Adhesive small bowel obstruction (ASBO) accounts for the majority of hospitalizations related to SBO following abdominal surgery. Delays in the management of ASBO are associated with longer hospital stays and increased mortality rates, making it imperative to establish an efficient way of determining which patients need surgical intervention.

PURPOSE

To evaluate the contribution of bedside small bowel follow-through (BSBFT) in the management of suspected ASBO.

MATERIALS AND METHODS

A single-site analysis of 320 patients who underwent BSBFT from August 2015 to 2019 was retrospectively performed. The presence of contrast in the colon on abdominal radiographs obtained at eight and 24 hours after administration and subsequent management (conservative versus surgical) was recorded.

RESULTS

Of the 320 BSBFT exams, 235 cases had colonic contrast present at eight hours. Twelve of those cases received surgical treatment, while the remaining 223 were managed conservatively. Forty-three cases showed colonic contrast at 24 hours despite not showing contrast at eight hours. Of these cases, 29 patients were managed conservatively, while 14 patients underwent surgery. Forty-two cases had no contrast at 24 hours, and 33 patients of those patients subsequently received surgical intervention, while nine were managed conservatively. Patients who had contrast on radiographs and underwent surgical interventions had either high clinical concern for postoperative complications or stagnant clinical progression.

CONCLUSION

BSBFT helps determine the management for suspected ASBO. ​Patients with colonic contrast on eight- or 24-hour abdominal images were more likely to be managed conservatively. However, the clinical context is important, since clinical factors may overrule the results of the BSBFT.
