We have identified a number of risk factors for incomplete CE procedures that can be used to risk-stratify patients and guide interventions to improve completion rates.

Most patients with previous incomplete colonoscopy can undergo a successful repeat colonoscopy at a tertiary care centre with instruments that are readily available to most gastroenterologists. Other modalities for evaluation of the colon should be deferred until a second attempt is made at an expert centre.

In patients with IDA without evidence of gastrointestinal bleeding, CE had a low diagnostic yield (25.7%), which increased to 45.5% after adjusting for low dietary iron intake and menorrhagia. However, CE did not alter management in most patients regardless of findings, and many of the lesions requiring intervention were within reach of standard endoscopes. No predictor of positive results was found. In this patient population, careful history taking and thorough endoscopy could improve CE utilization, although its value is still relatively limited.
