ABSTRACT
Objective: The objective of this study was to assess the association between colorectal neoplasia and sporadic duodenal adenoma. Methods: A retrospective case control study was conducted using the databases of two major teaching hospitals in Western Australia. The frequency of colorectal neoplasia in patients with sporadic duodenal adenomas was compared with that in a control group of patients presenting for endoscopies. The frequency of colorectal cancer in duodenal adenoma patients was also compared with the population incidence. Results: Of 56 sporadic duodenal adenoma patients, 34(61%) had been colonoscoped. When comparing the findings between patients with sporadic duodenal adenoma and an endoscoped control group, all colorectal neoplasias were significantly more common in the duodenal adenoma group (56% v 33%; odds ratio (OR) 2.4 (95% confidence intervals (CI) 1.1-5.4)). Although finding either advanced colorectal adenoma or cancer was also more common in duodenal adenoma patients (38% v 19%; OR 2.3 (95% Cl 1.0-5.2)), as was finding colorectal cancer alone (21% v 8%; OR 3.0 (95% CI 1.0-9.1)), the results were not statistically significant. However, the incidence of colorectal cancer was much greater in duoderial adenoma patients than in the population (p<0.001). Conclusions: Sporadic duodenal adenoma has a clinically important association with colorectal neoplasia. Thus patients with duodenal adenomas should undergo colonoscopy to detect colorectal neoplasia.

    Aberrant crypt foci (ACF) may represent pre-neoplastic lesions in the human colon. The prevalence of ACF detected using magnification chromoscopic colonoscopy is known to follow a stepwise progression from normal subjects to those with exophytic adenomas and colon cancer (CC).

    Background: Distal adenomas have been considered markers of proximal neoplasms. It also has been suggested that patients with small, distal adenomas do not require proximal examination of the colon. This study was conducted to determine the validity of the latter recommendation. Methods: From a...

    High Magnification Chromoscopic Colonoscopy (HNPCC) is the most common of the hereditary colon cancer syndromes approximating to 1.5% of the colon cancer (CC) burden in Great Britain. HNPCC is associated with right sided CC. In addition to exophytic polyps, flat and depressed lesions occur which...

    Background: Colonoscopic surveillance for hereditary non-polyposis colorectal cancer (HNPCC) reduces death rates, but early interval cancers still occur, probably due to missed small, aggressive adenomas.

    Background: An endoscopists adenoma detection rate (ADR) of less than 20 % correlates with high risk for occurrence of interval cancer. The impact of high-definition (HD) imaging on the ADR is discussed controversially. We aimed to investigate whether detection rates of individual endoscopists...
