What To Do In Clinical PracticeWhat To Do In Clinical Practice

Bringing it together

Integrating Capsule and Deep

Bringing it together

Integrating Capsule and DeepIntegrating Capsule and Deep Enteroscopy in suspected SI bleeding

Integrating Capsule and Deep Enteroscopy in suspected SI bleeding

Perform Capsule Endoscopy after Negative EGD and Colonoscopy (and perhaps second look endoscopy)

Review of Capsule EndoscopyAre findings equivocal and clinical suspicion low?

Consider repeat CE vs Cross-Sectional Imaging vs Observation

Should patient go directly to surgery?If not, then Deep Enteroscopy should be planned

Approach to Possible SI LesionApproach to Possible SI Lesion

Suggests Vascular Suggests Tumor or

D E t if

Suggests Vascular Lesion

Treat Those in Reach with Push Enteroscopy

even if not bleeding

Suggests Tumor or Inflammation

Cross-Sectional

Consider Push Enteroscopy or

colonoscopy if in reach

Negative Capsule

If Serious Problem or

Mild Anemia or Low Suspicion – Observe

with Iron Therapy

Deep Enteroscopy if Symptoms Persist

For Mild Anemia, few angiodysplasia, observe with iron therapy, stop antiplatelet therapy if

possible

Otherwise proceed with Deep Enteroscopy if

findings might prevent surgery

Cross Sectional Imaging is considered

complimentary and often very helpful

If Serious Problem or Suspicion High, then proceed with Deep Enteroscopy and/or

Cross sectional Imaging

Suspected SI BleedingImportant Points to Remember

U i CE d D E t di tiU i CE d D E t di ti• Using CE and Deep Enteroscopy, diagnostic yield is 40-80%

• Overlooked upper or lower GI source common; consider second look endoscopy

• Capsule Endoscopy is next best test - Yield higher if done soon after overt bleeding

• Overlooked upper or lower GI source common; consider second look endoscopy

• Capsule Endoscopy is next best test - Yield higher if done soon after overt bleeding

• Deep Enteroscopy and cross-sectional imaging are complimentary for detecting bleeding, tumors or inflammation

• Evaluate patient as close to bleeding episode as possible
