The altered anatomy can contribute to indigestion following surgery. [2] The procedure has also been associated with an increased incidence of iron-deficiency anemia . Iron-deficiency anemia develops in up to 45% of people who have had a Roux-en-Y anastomosis.
The anatomy and surgical technique for bowel resection varies based on the location of the removed segment and whether or not the surgery is due to malignancy. The below sections describe resection for non-malignant causes. Malignancy may require more extensive tissue resection beyond what is described here.
