OBJECTIVES: Prophylactic colectomy at a premalignant stage is the cornerstone of management of familial adenomatous polyposis (FAP). Before surgery, colonoscopy surveillance is recommended in children with FAP. This study aimed to examine the natural history of FAP in children by evaluating adenoma progression and factors influencing timing of colectomy. METHOD: Patients with FAP younger than 18 years at first surveillance colonoscopy and who had undergone more than 1 colonoscopy were identified. Demographic, endoscopic, genetic, and surgical data were retrieved. Cumulative adenoma (polyp) counts were obtained while accounting for any polypectomies during the study period. The rate of polyp progression and factors influencing the timing of colectomy were evaluated. RESULTS: Eighty-four patients (50% boys; mean age at first colonoscopy 13 years [standard deviation 1.97]) were identified, of which 83 had a family history of FAP. At first colonoscopy, 67 (79%) had <100 adenomas and 29 (35%) had colonic polyps identified despite rectal sparing. The median rate of polyp progression per patient was 12.5 polyps/year (range 0-145). Of the 45 (54%) patients who had undergone surgery, 41 (91%) underwent colectomy with ileorectal or ileodistal sigmoid anastomosis. Polyp progression did not alter the choice of surgical intervention in any patient. CONCLUSION: Our results suggest that adenoma number remains relatively stable in the majority of children under surveillance. Tailored surveillance intervals according to phenotype are a more appropriate strategy as recommended by recently published guidelines.

Segal J, Mullish B, Clark S, Marchesi J, Hart Aet al., 2020, P844 Higher proportions of genera and species in the Firmicutes phylum are associated with a healthy pouch compared with patients with chronic pouchitis, Journal of Crohn's and Colitis, Vol: 14, Pages: S652-S652, ISSN: 1873-9946

BackgroundStudies highlighting changes in bacterial composition in the ileoanal pouch are limited by heterogeneity in analysis techniques and sampling strategies Therefore, caution must be used when interpreting microbiota data. Similar to findings in IBD, a decrease in bacterial diversity and ‘dysbiosis’ are associated with acute and chronic inflammation in the pouch. Changes in Clostridium spp. and E. coli are associated with inflamed pouches and treatment response. This study aimed to compare the bacterial microbiota composition in patients with chronic pouchitis who responded to antibiotics vs. those who did not.MethodsPatients with confirmed chronic pouchitis defined by a pouch disease activity score ≥ 7 were treated with antibiotics. If patients were already on antibiotics, they were offered the opportunity to stop. Follow up was at 4 weeks to check clinical status. Patients who came off antibiotics who flared were given the opportunity to restart the antibiotics to prevent deterioration. Patients were analysed as either on antibiotics if they received antibiotics 2 weeks prior to the clinic or off antibiotics if they had stopped all antibiotics 2 weeks prior to follow-up. Stool was collected from patients on follow-up and DNA was extracted from this stool. Sequencing was performed on an Illumina platform. Statistical analysis was performed using STAMP 2.1.3 software with Welch’s two-sided t-test for comparing two groups with false discovery rate correction.ResultsThere were 28 patients in the cohort; 23 patients with chronic pouchitis and 5 healthy controls who had never had pouchitis. Ten patients were female. The median age of the cohort was 47 years (range 26–74 years). A total of 12 samples on antibiotics and 11 off antibiotics. There were 10 responders and 13 non-responders. There were no differences between responders and non-responders and no differences in those taking antibiotics vs. those not taking antibiotics with chroni

Objective: Current surveillance strategies for duodenal adenomatosis in familial adenomatous polyposis (FAP) miss malignancies and underestimate cancer risk in ampullary disease. This study aimed to evaluate the utility of endoscopic ultrasound (EUS) in the assessment of FAP patients with duodenal and/or ampullary polyposis referred for surgical intervention. Design: A retrospective analysis of FAP patients undergoing index EUS between December 2006 and May 2015 was performed. Follow-up was completed in January 2018, including review of all EUS procedures and surgical interventions (median follow-up 6 years). Results: Fifty-five patients underwent 188 EUS procedures. Six patients (11%) developed malignancy (three duodenal, three ampullary). Ampullary cancer risk was underestimated by Spigelman stage and overestimated by Kashiwagi classification. Ultrasound findings were poor predictors of malignancy, with common bile duct dilatation being the only finding present in one EUS prior to a diagnosis of ampullary cancer. The best predictors of ampullary malignancy were an ampullary polyp size >3 cm and an increase >1 cm in ampullary polyp size. Ampullary polyp size >3 cm provided the best predictive value, correctly identifying two of the three cases of ampullary cancer and both patients with high-grade dysplasia. EUS biopsy failed to detect malignancy later confirmed by surgical histology in two patients. Conclusion: EUS surveillance confers little additional benefit to standard endoscopic surveillance in FAP patients. The best predictor of ampullary malignancy is an ampullary polyp >3 cm; this could be regarded as a relative indication for surgery.
