Atrophy and neoplastic transformation of the ileal pouch mucosa in patients with ulcerative colitis and primary sclerosing cholangitis - A case control study

Stahlberg, D ; Veress, Bela LU ; Tribukait, B and Broome, U (2003) In Diseases of the Colon & Rectum 46(6). p.770-778
Abstract
INTRODUCTION: Patients with ulcerative colitis and primary sclerosing cholangitis have an increased risk of developing carcinoma both in the bile ducts and in the colon. PURPOSE: To investigate whether this patient group also has an increased risk of developing atrophy and neoplasia in the deal pouch mucosa after construction of a pelvic pouch with an ileoanal anastomosis or a continent Kock ileostomy. METHODS: Flexible video endoscopic examinations of the ileal pouch were performed in 16 patients with ulcerative colitis and primary sclerosing cholangitis and in 16 matched patients with ulcerative colitis without sclerosing cholangitis. Biopsies were sampled from different locations in the pouch for histologic assessment of mucosal atrophy... (More)
INTRODUCTION: Patients with ulcerative colitis and primary sclerosing cholangitis have an increased risk of developing carcinoma both in the bile ducts and in the colon. PURPOSE: To investigate whether this patient group also has an increased risk of developing atrophy and neoplasia in the deal pouch mucosa after construction of a pelvic pouch with an ileoanal anastomosis or a continent Kock ileostomy. METHODS: Flexible video endoscopic examinations of the ileal pouch were performed in 16 patients with ulcerative colitis and primary sclerosing cholangitis and in 16 matched patients with ulcerative colitis without sclerosing cholangitis. Biopsies were sampled from different locations in the pouch for histologic assessment of mucosal atrophy and dysplasia and for flow cytometric DNA analysis assessing chromosomal aberrations. RESULTS: The patients with sclerosing cholangitis developed moderate or severe atrophy in the pouch significantly more often (P < 0.01). Persistent severe mucosal atrophy was revealed in eight patients with sclerosing cholangitis and only in two controls. One patient with sclerosing cholangitis had high-grade dysplasia in multiple locations. Low-grade dysplasia was assessed in three patients with sclerosing cholangitis and in two of the controls. DNA aneuploidy was displayed in three patients, all with sclerosing cholangitis and dysplasia. All patients with neoplastic transformation had a pouch with ileoanal anastomosis and a long pouch duration (> 8 years). CONCLUSION: Patients with ulcerative colitis and primary sclerosing cholangitis with an ileal reservoir are more prone to developing mucosal atrophy in the pouch and seem to have a higher risk of neoplastic transformation in the pouch mucosa than patients with ulcerative colitis without sclerosing cholangitis.
