“…Completeness of the small bowel examination was achieved in all cases, which can be attributed to the long battery life of the Capsocam SV1. In a retrospective analysis from Canada, nearly 30% of 535 procedures were incomplete . The authors found a prior history of abdominal surgery, opiate medication, and hospitalized patients to be risk factors for an incomplete capsule endoscopy.…”

“…Other reported risk factors for incomplete studies include medications, systemic medical conditions, immobility, and previous small bowel surgery [3–5, 7]. To our knowledge, there has not been a large scale study to date looking at the effect of opioids on WCE transit times and completion rates.…”

Objective. Wireless capsule endoscopy (WCE) is commonly used to directly visualize the small bowel. Opioids have variably been linked with incomplete studies and prolonged transit times in heterogeneous cohorts. We aimed to investigate the effect of opioid use on WCE for inpatient and outpatient cohorts. Methods. We performed a retrospective review of patients receiving WCE at our institution from April 2010 to March 2013. Demographic data, medical history, and WCE details were collected. Transit times were compared by log-rank analysis. Multivariable logistic regression and Cox proportional hazard models were utilized. Results. We performed 314 outpatient and 280 inpatient WCE that met study criteria. In the outpatient cohort, gastric transit time (GTT) was not significantly different between opioid and nonopioid users. Completion rates were similar as well (88% and 87%, P = 0.91). In the inpatient cohort, GTT was significantly longer in patients receiving opioids than in patients not receiving opioids (44 versus 23 min, P = 0.04), but completion rates were similar (71% versus 75%, P = 0.31). Conclusion. Opioid use within 24 hours of WCE did not significantly affect completion rates for inpatients or outpatients. GTT was prolonged in inpatients receiving opioids but not in outpatients.

“…In this study, there was no significant differences among the 3 groups with respect to entry demographic morbidity factors like DM (23), abdominal surgery (19,24), and HD for CRF, which have been reported to be risk factors for incomplete bowel examinations. Likewise there was no significant difference among the 3 groups in CR values when age was factored in the analyses (seen in Table 3), in spite of the knowledge that the bowel peristalsis in elderly may be impacted by age.…”

The Relationship between Physical Activity Level and Completion Rate of Small Bowel Examination in Patients Undergoing Capsule Endoscopy

et al. 2012

Objective Capsule endoscopy (CE) allows direct examination of the small bowel in a safe, noninvasive and well-tolerated manner. Nonetheless, experience indicates failure to reach the cecum in 20-30% of patients within the 8 hour battery life. Attempts to improve the completion rate (CR) as defined by reaching the cecum have been unsuccessful. This study was to investigate the relationship between patients' physical activity and CR. Methods Between January 2009 and January 2010, 76 patients (44 men, 32 women; median age 64.5 yr) underwent CE for the diagnosis of small intestinal disorders. Indications for CE were obscure gastrointestinal bleeding/anemia (62 cases), others (14 cases). Patients were divided into an outpatient group (n=23), mild bed rest group (n=35) and strict bed rest group (n=18). Results For all patients, the average gastric transit time was 65.5 minutes, small bowel transit time was 301.4 minutes and the CR was 86.8%. However, the CR was 100% (23/23) in the outpatient group, an 85.7% (30/35) in the mild bed rest group, and 72.2% (13/18) in the strict bed rest group. The CR increased with physical activity of patients by Cochran-Armitage Trend Test (p=0.009). In multivariate logistic regression analyses, low physical activity was a significant risk factor for failure to reach the cecum during CE examination; adjusted OR: 3.39, 95% CI: 1.01-11.42 (p=0.048). Conclusion Our observations suggested that increasing physical activity would increase the likelihood of a complete bowel examination by CE. Further, for CE, inconvenient bowel preparations like the use of polyethylene glycol may be avoided.

Factors associated with incomplete small bowel capsule endoscopy studies

Abstract: 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.
