[Clinical practice using colon capsule endoscopy].

Area of Science:

• Gastroenterology
• Medical Devices
• Diagnostic Imaging

Context:

• Colorectal cancer screening remains a critical public health concern.
• Traditional colonoscopy presents challenges in patient compliance and procedure invasiveness.
• Capsule endoscopy has emerged as a less invasive alternative for visualizing the colorectum.

Purpose:

• To review the technological advancements and diagnostic capabilities of PillCam COLON capsule endoscopy (CCE), particularly the second-generation CCE-2.
• To evaluate the sensitivity and features of CCE-2 for detecting colorectal polyps and lesions.

Summary:

• PillCam COLON capsule endoscopy (CCE) utilizes a swallowable capsule for noninvasive colorectal examination.
• The second-generation CCE-2 features dual imagers with a 172-degree field of view each, providing nearly 360-degree colon coverage.
• CCE-2 incorporates adaptive frame rate (AFR) technology, capturing images at 35 frames/second when moving and 4 frames/second when stationary.
• Reported per-patient sensitivity for detecting polyps ≥ 6 mm with CCE-2 ranges from 84% to 91%.

Impact:

• These advancements in CCE technology may provide physicians with a valuable noninvasive option for colorectal lesion screening.
• Improved diagnostic accuracy and patient comfort could enhance screening compliance rates.
• Further research may establish CCE-2 as a primary screening tool or an adjunct to existing methods.
