Introduction: Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. The diversion through a colostomy or an ileostomy is sometimes required for disease control. In these patients, common stoma-related complications sum up with CD-related complications and often require revisional surgery.
Methods: The aim of the study was to assess stoma morbidity after surgery for CD and to identify the burden of CD-related or CD-associated complications. Thus, details of past medical history, surgery, and follow-up of 54 consecutive patients operated on for CD with any sort of stoma were retrieved from the stoma therapist prospectively maintained database.
Results: In our series, 23 patients had a colostomy, and 31 patients had an ileostomy. Complications occurred after stoma creation in 38 patients (70%) at a median of 1.3 months (interquartile range 0.6-7.2). CD-related complications arose in 8 patients (including pyoderma gangrenosum in 3 patients, peristomal fistulae in 2, granulomas in 2, and peristomal abscess in 1). Patients with CD-related complications tended to have a shorter disease duration (p = 0.07) and higher occurrence of CD-related complications was associated with end-stoma (p = 0.006). In this cohort, 11 cases had to be surgically treated for peristomal fistulae or abscess, parastomal hernia, prolapse, pyoderma gangrenosum, and recurrent CD.
Discussion/conclusions: In patients with CD, stoma creation is burdened by a high rate of postoperative complication and a relevant rate is specifically related to CD. Often these patients are required to be reoperated on to redo the stoma. Moreover, end-stoma configuration and aggressive CD phenotype are associated to a higher rate of complications.
