This may happen when there is a long stricture, many strictures close to each other, or a very inflamed section of the intestineThe section of gut, or gastrointestinal tract, from the stomach to the anus.. Removing the affected part is known as a resection. The two ends of the healthy intestineThe section of gut, or gastrointestinal tract, from the stomach to the anus. are then joined together in a procedure called intestinal anastomosisA surgical procedure to join two ends of healthy intestine after a section of diseased intestine has been removed..

This surgery can provide very effective relief from symptoms. However, there can be some complications, such as leakage or obstruction at the site of the anastomosis (join), infections, and short-bowel syndrome, with poor absorption of vitamins and minerals.

Following a resection, further problems can occasionally occur at the site of surgery. In some cases, another resection will be necessary.
