Small bowel capsule endoscopy and treat-to-target in Crohn's disease: A systematic review

Table 4 Advantages and limitations of small bowel capsule endoscopy in Crohn’s disease

Advantages	Limitations
Less invasive than conventional endoscopy	Risk of capsule retention in stricturing CD
No need for sedation	No therapeutic or biopsy capability
High diagnostic yield comparable to other endoscopic or imaging modalities	SB evaluation may be incomplete due to:
	Uncontrolled air insufflation
	Retention or delayed transition
	Limited battery life
	Impossible to maneuver
Direct mucosal evaluation	Longer procedure time compared to other modalities
Patient-friendly	Analysis is time-consuming for the physician
