Prophylactic colectomy for hyperplastic polyposis.
BACKGROUND
Hyperplastic polyposis (HP) is important to recognise as it increases the risk of adenomata which may develop dysplastic change or frank adenocarcinoma. We present the case of a 58-year-old woman with HP.


METHODS
Following a diagnosis of HP in this patient, it was noted that the number of polyps were progressively increasing over time, becoming pancolic and extending into the rectum. Genetic testing for a familial polypotic syndrome was negative. Histological analysis demonstrated that the majority of polyps were hyperplastic, but there were also serrated and tubular adenomata with foci of low-grade dysplasia. Whilst there was no evidence of frank malignancy or high-grade dysplasia, following a risk-benefit discussion the patient underwent a laparoscopic total colectomy with an ileal pouch formation.


CONCLUSIONS
This case highlights the complexity in the management of HP and that even in the absence of confirmed invasive disease, patients may elect to undergo prophylactic colonic resection.
