A short cut review was carried out to establish whether computed tomography (CT) is useful in the management of patients with suspected acute small bowel obstruction (SBO). A total of 348 papers were found using the reported search and manually cross referencing papers, of which 16 represented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these best papers are presented in table 33.. The clinical bottom line is that CT is a useful investigation in patients presenting with suspected SBO.
In an [adult patient presenting with suspected SBO] is [CT] useful in [the diagnosis of obstruction and strangulation].
A 65‐year‐old woman presents to the emergency department with signs and symptoms of SBO. She had previously had an abdominal hysterectomy. Plain abdominal radiograph (AXR) is non‐specific. You wonder whether abdominal CT would be useful in the management of a patient with presumptive SBO.
Medline 1950 to March 2006 using the OVID interface, combined with manual cross‐referencing (exp Intestinal obstruction/AND exp Intestine, Small/AND exp Tomography, X‐Ray Computed/) AND ((intestinal adj obstruction) AND CT).mp. limit to (humans and English language).
A total of 491 papers were found of which 16 were relevant to the topic and one systematic review incorporating 11 of these papers (table 33).
Published literature supports the use of CT as a sensitive and specific test for small bowel obstruction. The evidence supports the proposal that CT provides reliable information regarding cause of the obstruction and presence of bowel strangulation.
CT is a useful investigation in patients presenting with suspected SBO.
