Abstract
Objective
This study aims to evaluate the clinical characteristics of patients with postoperative ulcerative colitis developing extremely early-onset pouchitis within 4 weeks of restoration of gastrointestinal continuity.
Material and Methods
This retrospective study involved 225 consecutive patients from January 2000 to May 2011 who underwent ileal pouch–anal anastomosis for ulcerative colitis with a minimum follow-up of 12 months. Extremely early-onset pouchitis was defined as pouchitis developing within 4 weeks of restoration of gastrointestinal continuity. Patients with pouchitis were divided into extremely early-onset pouchitis and non-extremely early-onset pouchitis groups for comparison.
Results
Of 212 patients who met the inclusion criteria, 62 had pouchitis (29.2 %). Eight (3.8 %) patients developed extremely early-onset pouchitis. There was a significant difference in the dosage of steroid per month just before colectomy between the two groups (P = 0.039). The modified Pouchitis Disease Activity Index score for patients with extremely early-onset pouchitis was higher than in patients with non-extremely early-onset pouchitis (P = 0.0009). The occurrence of extremely early-onset pouchitis was associated with the development of chronic pouchitis (P = 0.0056).
Conclusion
Extremely early-onset pouchitis may be related to high steroid dosages before colectomy and may be more severe than pouchitis that occurs >4 weeks after restoration of gastrointestinal continuity.
