Implantation of a duodenal–jejunal bypass sleeve for managing obesity

The procedure

This procedure aims to slow digestion by acting as a barrier between food and the upper part of the bowel.

Under a general anaesthetic or sedative, a thin flexible tube with a camera on the end (endoscope) is inserted into the patient's mouth and moved through the stomach into the bowel. The sleeve is moved through the tube and attached to the upper part of the bowel.

Straight after the procedure, patients can only have fluids, and then move on to eating semi-solid foods and solid foods over several weeks. The sleeve is removed within a year.
