Abstract

Background/Aims: Limited knowledge exists regarding the optimal timing and relative advantages of primary surgery compared to medical treatment in ileocecal Crohn's disease (CD). This study aimed to compare long-term outcomes between medication-based treatment versus surgery in newly diagnosed ileocecal CD patients in an Asian population. Methods: Among the 885 patients diagnosed with CD and enrolled in the study site hospital cohort between 1980 and 2013, 93 (10.5%) had ileocecal CD. Patients were categorized into either the surgical or medical remission group based on their initial management strategy that led to remission. The rates of relapse, hospitalization, and surgery after achieving remission were compared using Kaplan-Meier curves. Results: The numbers of patients assigned to surgical and medical remission groups were 15 (17.0%) and 73 (83.0%), respectively. The surgical remission group exhibited a lower relapse rate and longer maintenance of remission (10.7 vs. 3.7 yr; p = 0.017) during a median follow-up of 6.6 years. Hospitalization after the first remission tended to be lower in the surgical remission group (p = 0.054). No cases required repeated intestinal resection after the initial surgical remission, whereas a 23% surgery rate was reported at 5 years after initial medical treatment (p = 0.037). In the multivariable analysis, the initial medication-based treatment was significantly associated with relapse (hazard ratio = 3.23, p = 0.039). Conclusions: In selected cases of localized ileocecal CD, ileocolic resection might be a favorable alternative to medication-based treatment, as it demonstrates a lower relapse rate and longer maintenance of remission.
