this paper, "Rectosigmoid perforation and intestinal evisceration from transanal suction", I mentioned in a thread last Oct when The Sponge spoke of Therma Spa tubs.
another paper, by Hultman CS, Morgan R. reports:
"Transanal suction from a swimming pool drain can result in intestinal evisceration. We report the eighth such case, followed by a literature review, description of the mechanism, and management guidelines. This bizarre injury, which has devastating consequences for the children involved, is completely preventable by installation of semi-permanent, anti-vortex grates."
