Gender, age, and concomitant diseases of melanosis coli in China: a multicenter study of 6,090 cases.

ABSTRACT:

Backgrounds and aims

Melanosis coli (MC) is a noninflammatory, benign, and reversible colonic disorder, but its detection rates in China are unclear. We therefore aimed to analyze the epidemiological characteristics of MC in China.

Methods

We assessed the detection rates, associated factors and concomitant diseases of MC in the patients who underwent colonoscopy at eight medical centers across five regions of China between January 2006 and October 2016. All data were procured from the electronic database established at each participating institutions.

Results

Among the 342,922 included cases, MC was detected in 6,090 cases (detection rate = 1.78%, 95% confidence interval, 1.73%-1.82%) at a mean age of 60 years. The detection rate gradually increased yearly, and along
