Outcome of patients with obscure gastrointestinal bleeding after capsule endoscopy: report of 100 consecutive cases

Area of Science:

• Gastroenterology
• Medical Diagnostics
• Endoscopy

Background:

• Obscure gastrointestinal bleeding presents a diagnostic challenge.
• Capsule endoscopy (CE) shows promise but requires further evaluation for diagnostic yield.

Purpose of the Study:

• To evaluate the sensitivity, specificity, and outcomes of CE in patients with obscure gastrointestinal bleeding.
• To determine the diagnostic yield of CE across different patient subgroups.

Main Methods:

• One hundred patients with obscure GI bleeding underwent CE.
• Patients were categorized into three groups based on bleeding presentation: ongoing overt bleeding, previous overt bleeding, and occult bleeding with iron-deficiency anemia.

Main Results:

• CE demonstrated a high diagnostic yield, particularly in patients with ongoing overt bleeding (92.3%).
• Sensitivity and specificity were 88.9% and 95%, respectively.
• CE led to successful treatment in 86.9% of actively bleeding patients; capsule retention occurred in 5 patients.

Conclusions:

• Capsule endoscopy is an effective tool for diagnosing obscure GI bleeding.
• Patients with ongoing overt or obscure-occult bleeding are ideal candidates for CE.
• Early CE can expedite diagnosis, facilitate treatment, and reduce the need for less effective investigations.
