On the Bleeding Edge: Mastering GI Emergencies and Inpatient GI Consultation (On-Demand)

Pdf Summary

This presentation reviews the evaluation and management of suspected small bowel bleeding, using three clinical cases to illustrate diagnostic strategy and treatment options.<br /><br />Small bowel bleeding accounts for about 5–10% of gastrointestinal bleeding and should be considered after negative or nondiagnostic EGD and colonoscopy. Causes include angioectasias, tumors, inflammatory/infectious disease, and bleeding related to surgery or altered anatomy. The work-up depends on patient stability and bleeding pattern. In hemodynamically unstable patients with active bleeding, CT angiography is preferred because it is rapid and highly accurate. In stable patients with intermittent bleeding, tagged red blood cell nuclear scans can detect lower bleeding rates. Video capsule endoscopy (VCE) has the highest yield when done early—especially within 48–72 hours of overt bleeding—and can guide deep enteroscopy by estimating small bowel transit time. Push enteroscopy and double-balloon enteroscopy are useful therapeutic tools, especially when the bleeding source is reachable.<br /><br />The cases highlight common real-world challenges: NSAID-related injury with diffuse blood throughout the bowel, obscure bleeding requiring staged endoscopic evaluation, and recurrent bleeding from multiple angioectasias in a patient with ESRD and anticoagulation. The talk emphasizes practical techniques for successful enteroscopy, such as using a pediatric colonoscope, clipping the first bleeding site, and marking lesions for future therapy.<br /><br />Long-term management focuses on minimizing rebleeding and transfusion needs. This includes reviewing anticoagulant and antiplatelet therapy, considering cardiology input, using iron replacement, and in selected patients, medical therapies such as octreotide, thalidomide, or bevacizumab. The main take-home message is to plan early, choose the highest-yield test based on the clinical scenario, and combine endoscopic with medical management to reduce morbidity.
