summary/abstract:

PURPOSE : The main operative method in familial adenomatous polyposis (FAP) patients is restorative proctocolectomy with “J”-shaped pouch and temporary loop ileostomy. The aim of the study was the analysis of the frequency of the dysplasia and inflammation in the intestinal pouch and prognosis of the clinical course in FAP patients after restorative proctocolectomy.

METHODS : A group of 165 FAP patients (86 females and 79 males, mean age 22.49 ± 12) subjected to a restorative proctocolectomy in the years 1985-2009 was analyzed. Clinical data coming from follow-up observation in the period of 2004-2009 were evaluated. In all patients, clinical examination and endoscopy with polypectomy and/or biopsy of pouch mucosa were done.

RESULTS : The mean time of pouchitis occurrence after an ileal pouch-anal anastomosis was 6 months. Mean time for low-grade dysplasia was 14 months. The time difference of low-grade dysplasia after the above procedure as compared to pouchitis alone was substantial. Mean time for high-grade dysplasia was 16 months and for neoplasia even 19 months. It was estimated that early pouchitis happening within the first year after surgery occurs in 5% of patients, low-grade dysplasia 4 years later in 7% of cases, high-grade dysplasia 7 years later in around 10% of patients and neoplasia 14 years after surgery in 15% of cases.

CONCLUSIONS : In conclusion, the Polyposis Registry encompassing whole country is the best way of controlling FAP patients. The regular lifelong endoscopic monitoring gives the opportunity of the early detection of the dysplasia and can protect against neoplasia.
