Impact of Treatment Adjustment on the Endoscopic Prognosis of Postoperative Anastomotic Lesions in Patients With Crohn's Disease.

Although subgroup analyses demonstrated significant adjustment treatment benefits (endoscopic mucosal healing and ulcer improvement, P < 0.05) in some subgroups (no smoking patients, no perianal disease, number of biologics ≤1, no residual disease, mild anastomotic ulcers, intermediate anastomotic ulcers, and NLR ≤ 2), the interaction tests between these variables (smoking, perianal lesions, number of biologics, residual lesions, types of anastomotic ulcers, and NLR) and adjustment treatment did not reach statistical significance (all p-interaction >0.05; see Supplementary Figures 4 and 5, Supplementary Digital Content, http://links.lww.com/CTG/B315 ).
