    Typical mucosal pigmentation seen in melanosis coli
    Melanosis coli is a pigmentation of the rectal and colonic mucosa due to use (or abuse) of anthraquinone type laxatives. Histologic specimens show numerous macrophages containing a granular dark pigment in the lamina propria. Withdrawal of the offending laxative, which nearly always can be substituted with a bulk laxative, is sufficient treatment.

The Best Image Library in the World!

That is what we would like Gastrolab Image Library and Endoscopic Archives to be.

Perhaps We can achieve this together? Many of You have ecxellent endoscopic images just waiting for publication. When published they can be an invaluable resource for young endoscopists and for gastroenterologic education.

So, please email Your images here
together with a short caption, a notice that our site is permitted to publish them and information if You want a copyright sign together with You email address (in which case possible commercial publishers can contact You to get permission to publish Your images).

Together we can make the best and most complete Image Library in the World!
