[Distal hyperplastic polyps as a marker for advanced neoplasm of the proximal colon. Our experience].
Clin Ter 2007 Sep-Oct; 158(5):421-4CT

Abstract

BACKGROUND AND AIM

While, several studies indicate that there is an association between proximal and distal colorectal adenomas, no agreement seems to be between the presence of distal hyperplastic polyps and proximal neoplasia. The aim of this study was to investigate, retrospectively, the possible correlation between the distal hyperplastic polyps and proximal colorectal neoplasia.

MATERIALS AND METHODS

In our GI Unit, from 1st February 2006 to 24 November 2006, we performed 142 polypectomy. Patients were 36 females and 80 males, with a median age of 66 years [range: 38-87 years]. All of the polpys were resected during colonoscopy and sent for histological study. Chi-square test was used for statistical analysis. A probability value of P< or =0.05 was considered to be statistically significant.

RESULTS

Histological study showed the following results: 33 hyperplastic polyps (8 F, 21 M; median age 63 years), 100 adenomas (26 F, 61 M; median age 67 years) and 2 inflammatory polpys (2 F, 0 M; median age 71 years). The rectal localization was associated with a significantly higher frequency of hyperplastic polyps (63.6% vs 23.5%), OR: 5.688 (95% C.I. 2.445-13.230) (p<0.0001). Five hyperplastic polyps of the rectum were associated with 5 adenomas located 1 in the rectum, 2 in the sigmoid colon, and 1 in the descendens colon and 1 in the ascendens colon. While, 5 adenomas were associated with 5 adenocarcinoma.

CONCLUSIONS

Guidelines from the American College of Gastroenterology and the American Society of Gastrointestinal Endoscopy do not recommend colonoscopy for patients with distal hyperplastic polyps. Also our study is in keeping with the data of the literature and it confirmed that rectal localization is associated with a higher prevalence of hyperplastic polyps.
