[Pelvic pouches].

Since Nissen performed his first ileo-anal anastomosis for a benign large bowl disease in 1933, restorative proctocolectomy has undergone substantial developments, thus especially in the last two decades. Different pouch designs (J-, S-, W- and H-pouch) obtain normal defecation in patients treated with proctocolectomy. Many groups prefer the J-Pouch for it's technical simplicity and good results.
