Small bowel capsule endoscopy in clinical practice: a multicenter 7-year survey

Area of Science:

• Gastroenterology
• Medical Technology
• Clinical Practice

Background:

• Existing data on small bowel capsule endoscopy (SBCE) often derive from limited, highly selected patient groups.
• Real-world clinical practice data for SBCE are crucial for understanding its broader utility.

Purpose of the Study:

• To evaluate the utilization, indications, diagnostic outcomes, and safety of SBCE in a large, defined geographical area (Lombardia, Italy).
• To assess practical challenges and complications associated with SBCE in routine clinical settings.

Main Methods:

• A questionnaire-based survey was distributed to 29 centers in Lombardia performing SBCE.
• Data were collected from 23 participating centers covering the period 2001–2008.

Main Results:

• SBCE procedures and the number of performing centers significantly increased between 2001 and 2008.
• Obscure gastrointestinal bleeding (43.4%) and unexplained anemia (23.9%) were primary indications.
• Positive diagnostic yield was 50%, with highest yields for OGIB (62.5%) and polypoid syndromes (74.1%).
• Capsule retention occurred in 2.1% of patients, with most resolving spontaneously.

Conclusions:

• SBCE utilization expanded significantly in Lombardia over a 7-year period.
• The study confirms a high diagnostic yield and acceptable safety profile for SBCE in clinical practice.
• Findings support SBCE as a valuable tool for diagnosing small bowel pathologies.
