Bone assessment in patients with ileal pouch–anal anastomosis for inflammatory bowel disease

Background Patients with ulcerative colitis are at risk of low bone mineral density (BMD). Proctocolectomy with ileal pouch–anal anastomosis (IPAA) for ulcerative colitis diminishes the risk of bone disease. The aims of this study were to assess the mechanism of low BMD and to measure bone density changes after IPAA.
