Long-term compliance with endoscopic surveillance for familial adenomatous polyposis

Aim
The study assessed compliance of patients with familial adenomatous polyposis (FAP) with endoscopic surveillance.

Method
In this nationwide, cross-sectional study, individuals from FAP families registered with the Netherlands Foundation for the Detection of Hereditary Tumours were invited to complete a questionnaire on endoscopic screening experiences.

Results
A total of 328 individuals were eligible for the study of whom 85 were at risk for FAP, 108 had an intact rectum after a colectomy with ileorectal anastomosis (IRA), and 135 had had a pouch following a proctocolectomy with ileoanal anastomosis (IPAA). Based on medical record data, 20% of the at-risk group and 26% of the IRA-group were found to be undercompliant with surveillance advice which was associated significantly with perceived self-efficacy, use of sedatives during surveillance, pain after surveillance and low perceived benefits of surveillance (P < 0.05).

Conclusion
One in five individuals at risk for FAP and one in four with a retained rectum are undercompliant with screening advice. We recommend that sedatives should be patient-tailored for FAP individuals undergoing surveillance and that adequate pain medication be provided after endoscopy.
