  • Title: Reoperations at the ileostomy in Crohn's disease reflect inflammatory activity rather than surgical stoma complications alone.

    Abstract:
    After ileostomy construction for Crohn's disease reoperations due to ileal recurrences are thought to be unusually rare, whereas reconstructions of the ileostomy due to stoma complications are considered to be unusually frequent. It remains unclear why the natural course of a disease as well as outstanding results of a standardized surgical procedure should be perverted. Therefore reconstructions of the ileostomy in 92 patients colectomized during a 12.5-year period and followed up for 5.4 years were analyzed concerning preoperative indication and postoperative histology. In 28 patients (30.4%) a total of 42 reoperations were necessary. The clinical indication was prestomal recurrence in 5 reoperations (11.9%) and stoma complications in 37 (88.1%). In contrast, ileal recurrence was demonstrated histologically in 28 specimens (66.7%) and healthy ileum in the rest. There was a statistically significant association between fibrotic recurrence and stoma stenosis/retraction and a trend for association between penetrating recurrence and peristomal ulceration. The cumulative risk for a first reoperation due to clinical recurrence was calculated at 3.3% and 14.0% at 5 and 10 years postoperatively, whereas the corresponding figures for stoma complications were 25.7% and 40.0%. In contrast, the cumulative risk that a recurrence was found histologically on the occasion of the reoperation was 23.0% and 35.0%, while the probability that the ileum was healthy in the case of a stoma complication remained low. In conclusion, most reoperations after ileostomy-construction in Crohn's disease are associated histologically with recurrent inflammation. The accentuation of the inflammatory recrudescence at the stoma itself or the prestomal ileum is decisive for the clinical presentation as stoma complication or intestinal complication. These findings reinforce both well known characteristics of the inflammatory disease and of established surgery.
