A simple and safe technique for examining the ileal pouch in the post-
operative period is described, and the findings in 85 patients reviewe
d. Extravasation from the ileo-anal anastomosis was seen in 10/85 (11%
). In 14/85 (16%) the lateral view of the filled pouch showed a presac
ral space > 4 cm, which in 10 (71%) was due to a significant abnormali
ty: six having an anastomotic leak with presacral abscess, two a large
presacral haematoma, and two an abscess without anastomotic leak. Pou
chography is recommended as a routine examination prior to closure of
the covering ileostomy.
