Capsule endoscopy

Use of video capsule endoscopy in the setting of recurrent subacute small-bowel obstruction

HYPOTHESIS

Video capsule endoscopy (VCE) can be used to diagnose subacute intestinal obstruction in patients with otherwise negative imaging studies.

PATIENTS AND METHODS

Nine patients with symptoms consistent with intermittent small-bowel obstruction who received a VCE and ultimately required surgical intervention.

RESULTS

Patients were identified who had symptoms consistent with subacute bowel obstruction and a negative diagnostic work-up prior to VCE. All 9 patients underwent several radiologic and endoscopic examinations with no clear etiology for their symptoms. Ultimately, in every case, a stricture or mass was found to be the cause of the obstruction at either the time of VCE or exploratory laparotomy/laparoscopy.

CONCLUSIONS

Patients can have a small-bowel stricture or mass that can cause symptoms of subacute small-bowel obstruction. Diagnosis of the lesion may be difficult in these patients and can often result in multiple nondiagnostic radiologic and endoscopic examinations. VCE can be helpful in finding these lesions, leading to surgical resection of the diseased bowel and a cure for the patient's signs and symptoms.

Capsule endoscopy and imaging tests in the elective investigation of small bowel disease

Capsule endoscopy enables high-resolution depiction of small bowel mucosa and has been shown, by several studies, to have a high diagnostic yield in a variety of small bowel diseases. In this review, we critically assess the contributions of capsule endoscopy and imaging tests in common small bowel disorders. Radiological tests that only assess the small bowel mucosa will be less useful in the era of capsule endoscopy.
