Role of wireless capsule endoscopy in the follow-up of inflammatory bowel disease

Table 2 Key studies describing the role of wireless capsule endoscopy on the assessment of mucosal healing in Crohn’s disease patients under treatment

	Ref.	Treatment	Indication	Patients (n)	Conclusion
CD	Niv et al[2]	Yes	SB mucosa evaluation of known CD patients	19	Musocal findings are independent from clinical and laboratory parameters
CD	Hall et al[1]	Yes	SB mucosal healing and deep remission rates assessment on 12 wk of treatment of known symptomatic CD patients	43	Symptomatic and biochemical response to treatment is not mirrored by mucosal healing
CD	Hall et al[33]	Yes	SB mucosal healing and deep remission rates assessment on 52 wk of treatment of known symptomatic CD patients	43	Symptomatic and biochemical response to treatment appears to be mirrored by endoscopic remission in 42% of individuals
CD	Efthymiou et al[3]	Yes	SB mucosal healing assessment of known symptomatic CD patients	40	Clinical response does not correlate closely with mucosal healing in patients with CD of the small bowel
CD	Tsibouris et al[32]	Yes	Assessment of detection rate of small bowel ulcerative lesions and completion rate in CD patients in acute phase and remission	102	SB aphthous ulcers are present a month after entering clinical remission

CD: Crohn’s disease; SB: Small bowel; CRP: C-reactive protein.
