Endoscopic full-thickness resection (FTRD)
Until a few years ago, it was difficult to remove scarred polyps, tumors under the mucous membrane or flat tumors with an endoscope and snare. In most cases, surgery was then necessary. With the endoscopic full-thickness resection device (Ovesco Endoscopy - FTRD), a new instrument is now available. It enables partial removal of the bowel wall, which is simultaneously closed again with a clip. The technique can be used in the colon or rectum. You can see an example video here: YouTube ►
During FTRD, a special cap is placed on the tip of the endoscope. A small pair of forceps grips the intestinal wall in the affected area and pulls it with all its layers into the cap. A clip is then placed around the now retracted section of bowel and this is cut out using a loop. The clip is a short-term implant that prevents a hole from forming in the bowel wall.
In many cases, the technique makes it possible to perform a full-wall resection of the colon area in question in order to be able to examine sufficient tissue. Until now, this usually required surgery. However, the technique is also used when it is unclear whether all parts of a polyp or early carcinoma have been completely removed. The FTRD has so far only been used in the colon. Modified instruments for use in the stomach and small intestine are currently being evaluated at our clinic as part of clinical studies.
Full-thickness resection is performed exclusively under inpatient conditions. Information and advice about the procedure and the possible risks is provided in our therapeutic endoscopy consultation hours.
