title: A retrospective study of clinico-pathological characteristics of colonic polyps in adults seen at a tertiary care centre.
abstract: OBJECTIVE
  To analyse morphological types, location in the large bowel and demographic characteristics of colonic polyps.
  
  
  METHODS
  The retrospective descriptive study was conducted at the Department of Pathology, Sultan Qaboos University Hospital, Muscat, Oman, and comprised biopsy specimens of colonic polyps from patients related to a two-year period from 2011 to 2012. Demographic data, types of polyps, anatomical location and grade of dysplasia were analysed. SPSS 20 was used for statistical analysis.
  
  
  RESULTS
  There were 160 biopsy specimens from 143 patients. Of the patients, 91(63.6 %) were male and 52(36.4%) were female. The mean age was 55.27+-14.2 years. Of the 160 polyps, 37((23.1%) were in the rectum. The most common type was the adenomatous polyp in 88(55.0%) cases followed by hyperplastic polyps 51(31.9%) and inflammatory polyps 21(13.1%). Of the 88 adenomatous polyps, 23(26%) showed high-grade dysplasia.
  
  
  CONCLUSIONS
  The commonest colon polyp type was adenomatous polyp. Screening programmes, such as stool occult blood testing and colonoscopies, are recommended.
