Double-headed small-bowel capsule endoscopy: Real-world experience from a multi-centre British study.

Area of Science:

• Gastroenterology
• Medical Imaging
• Endoscopy

Background:

• Capsule endoscopy (CE) is a standard tool for investigating small-bowel (SB) pathology.
• Conventional single-headed (SH) CE has limitations in visualizing the entire SB mucosa.
• Double-headed (DH) CE offers the potential for improved diagnostic yield.

Purpose of the Study:

• To compare the diagnostic performance of DH CE versus SH CE in a real-world clinical setting.
• To evaluate the impact of DH CE on clinical diagnosis and patient management.
• To assess the utility of DH CE in various SB conditions, including bleeding, inflammation, and neoplasia.

Main Methods:

• A multicentre study involving 204 patients undergoing routine SB CE at 4 UK tertiary referral centres.
• Patients received DH CE instead of conventional SH CE.
• Expert reviewers analyzed anonymized and randomized DH recordings, comparing findings with SH examinations.

Main Results:

• DH CE provided additional diagnostic information in 14.7% of cases, impacting diagnosis.
• Significant differences were observed in 28.7% of SB bleeding cases and 35.7% of IBD cases.
• SH CE missed clinically significant findings such as angiectasias, SB inflammation, and masses in several patients.

Conclusions:

• DH CE offers enhanced visualization and provides more comprehensive information compared to SH CE.
• The increased diagnostic yield of DH CE has the potential to alter clinical diagnosis and patient management.
• Routine adoption of DH CE for SB assessment is recommended for improved patient care.
