The present invention provides a device that protects the tissue in the posterior part of the introitus vaginae, i.e. the commissura posterior. The origin of perineal tear starts here when the segment is stretched to double or triple its length during delivery of the head. Tears can be more extensive into the perineal body, continue into the anal sphincter and in worse cases even through the whole perineum into the anal canal. In use the device may protect against perineal tears of the posterior vaginal wall into the mucosa, perineal skin, muscles, even more profound down to the anal sphincter muscle and into the rectum and the rectal mucosa.

The invention relates to fatty acid stimulation of rectal mucosa initiating the process of defecation, acting as a laxative. Furthermore, the invention relates to the usage of free fatty acids, fatty acid mixtures and fatty acid extracts from marine lipids in pharmaceutical formulations such as suppositories, ointments, tablets and gelatin capsules for treatment and prevention of multiple disorders like constipation, hemorrhoids, bacterial infections (e.g. helicobacter pylori), viral infections (e.g. herpes simplex virus infections) and inflammations, as well as against fissura ani and pruritus ani.

A device for collection of exfoliated cells from the rectal mucosa comprises a hollow, cylindrical body having an inflatable and invertible flexible membrane attached to one end thereof. Applying positive pressure to inflate the membrane after the device is inserted, preferably through a rectal access tube, into the rectum causes exfoliated cells to be collected on the surface of the membrane. Before removal of the device, negative pressure is applied and the membrane, along with the collected sample of exfoliated cells, is deflated, inverted and withdrawn into the body of the device, thereby avoiding contact of the collected sample with body surfaces or the rectal access tube as the device is removed from the rectum.
