Evolutive study of the functional results after restorative proctocolectomy for ulcerative colitis.
OBJECTIVE
Evolutive study of the functional results after restorative proctocolectomy for ulcerative colitis.


METHODS
Prospective study in 24 patients with an ileoanal "J" pouch (n = 8: mucosectomy and hand-sewn anastomosis; n = 16: stapled anastomosis without mucosectomy). A clinical survey was carried out during two evolutive follow-ups of the functional pouch (medians: 14.5 and 39.0 months) as well as an anorectal manometry study during the preoperative period and in two follow-ups after the creation of the pouch (medians: 6.0 and 35.5 months).


RESULTS
The mean frequency of defecation per 24 hours and per night was significantly reduced in the first follow-up (5.5 [24 h]; p < 0.003 and 1.0 [per night]; p < 0.009) compared with the postoperative period (7.9 [24 h] and 1.4 [per night]), with no significant changes in the second follow-up (5.5 [24 h] and 0.9 [per night]). At the same time, it has been significantly lower in patients with stapled anastomosis in the different evolutive follow-ups. One patient (4.2%) had major fecal incontinence in the two evolutive follow-ups and 7 (29.2%) and 6 (25%) patients had minor incontinence in the first and second follow-up respectively. The mean maximum resting anal pressure in the first follow-up was significantly lower (p = 0.002) in patients with mucosectomy than the values observed in patients with stapled anastomosis (35.4 vs 68.0 mmHg). In the second follow-up increased significantly (p = 0.046) only in patients with mucosectomy (55.1 mmHg). Recto-anal inhibitory reflex was present in 2 (10%) and 9 (45%) patients in the first and second follow-up respectively.


CONCLUSIONS
The functional results improve significantly with the follow-up time, fundamentally during the first year of the functional pouch.
