Ileal pouch-anal anastomosis (IPAA) is the procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis. This two-stage procedure with a temporary diverting ileostomy avoids the catastrophic consequences of anastomotic leakage. We set out to determine the incidence and effect of asymptomatic pouch sinuses detected prior to ileostomy closure on the outcome of IPAA. A total 1600 IPAAs performed at the Mayo Clinic were reviewed. Forty-one (2.6%) asymptomatic sinuses were treated expectantly. There were 22 males and 19 females who had a median age of 32 years (range 14 to 58 years). The median time to ileostomy closure was 5.9 months (range 4 to 11 months). Five patients required further surgery following closure of ileostomy. The pouch function in these five patients was similar to that in the remainder of the group. Patients with a persistent sinus at the time of ileostomy closure had the same function as the main cohort. This group had a median of five (range 2 to 12) stools during the day and two (range 0 to 4) at night. The total number of stools per 24 hours was seven (range 2 to 14). Frequent incontinence occurred in 9.7% and 7.3% during the day and at night, respectively. Only 2.4% (1/41) were disappointed with the results of the operation and 80.4% (33/41) found their quality of life improved. Functional outcomes were comparable to those achieved with uncomplicated IPAA. Radiologically detected asymptomatic sinuses can be treated expectantly with a low rate of pouch loss and subsequent surgery. This is not considered a serious setback inasmuch as long-term function and quality of life are comparable to that achieved with IPAA without sinus tracts.
