A patient is described with arthritis of both wrists and tendinitis of
one achilles tendon in the presence of severe pouchitis. The rapid di
sappearance of arthritis and tendinitis after removal of the pouch str
ongly suggests their relationship. The pathogenesis of arthritis in po
uchitis has not been elucidated but may be the same as in ulcerative c
olitis. Rheumatologists should be aware of the occurrence of arthritis
in patients with ulcerative colitis after the construction of an ileo
-anal anastomosis with a so-called pouch.
