Prospective postsurgical capsule endoscopy in patients with Crohn’s disease

Figure 1 Lewis score (median and quartile) for each tertile of the residual small bowel, divided into 3 equal portions on the basis of the capsule endoscope transition time shortly after surgery. A: Total Lewis score (LS) (edema + ulcer + stenosis scores); B: LS for edema; C: LS for ulcers. NS: Not statistically significant difference (Mann-Whitney U test).

Figure 2 Number of aphthae or erosions across tertiles soon after surgery (median and quartile). NS: Not statistically significant difference.

Figure 3 Changes over time in the total Lewis score from the time shortly after surgery to 6-8 mo later (n = 13). The total Lewis score (LS) increased by 100 or more (corresponding to progressive recurrence) in 5 patients, decreased by 100 or more (improved) in 5 patients, and changed by -99 to +99 (unchanged) in 3 patients.

Figure 4 Changes in the total Lewis score from shortly after surgery to 6-8 mo later, analyzed in relation to the postoperative treatment. A: In the anti-tumor necrosis factor (TNF) α antibody treatment group (n = 9), the rating was progressive recurrence in 4 patients, improved in 4 patients, and unchanged in 1 patient; B: In the group without anti-TNFα antibody treatment (n = 4), the rating was progressive recurrence in 1 patient, improved in 1 patient, and unchanged in 2 patients.
