Background According to recent literature, extended colectomy (EC) and segmental colectomy (SC) are equally effective for colonic Crohn’s disease (CCD), with no differences in terms of postoperative morbidity, incidence of long-term recurrence and definitive stoma, but earlier recurrence is observed in patients with SC. Our objective was to evaluate our comparative results between EC and SC. Methods All consecutive patients undergoing surgery for CCD (EC vs. SC) in our Centre were included and compared and we evaluated postoperative morbidity, long-term clinical and surgical recurrence. Results One hundred and twelve patients (mean age at diagnosis of CD, 31 ± 17 years, mean age at surgery 42 ± 17 years) with CCD underwent EC (n = 45) or SC (n = 67); 62 (55%) patients presenting concomitant small bowel disease, 10 (9%) an extra-intestinal manifestation and 16 (14%) were active smokers. Postoperative morbidity was 8/45 (18%) in case of EC vs. 9/67 (13%) in case of SC (NS). In EC group, 8/8 (100%) complicated patients vs. 16/37 (43%) uncomplicated patients were under anti-TNF before surgery (p = 0.04). This significant difference was not showed in SC group. After a median follow-up of 40 ± 34 months (range 1–130), clinical recurrence incidence was 15/45 (33%) in EC vs. 27/67 (40%) in SC patients (NS) and surgical recurrence was 8/45 (18%) in CE vs. 13/67 (19%) in CS patients (NS). Recurrence of the disease occurred after 19 ± 20 months (range, 1–74) in EC vs. 14 ± 26 months (range, 1–130) in CS patients (p = NS). Conclusion Our study confirms that in case of surgery for CCD, EC and SC are equally safe and feasible but recurrence happens earlier after SC than EC. Additionally, the role of anti-TNF is confirmed for postoperative complications.
