Ileal resection is a surgical procedure that involves the removal of a portion of the ileum, which is the last part of the small intestine. This surgery is often performed to treat conditions such as Crohn's disease, tumors, or blockages. After the affected section is removed, the remaining parts of the intestine are usually reconnected. The procedure can help alleviate symptoms like abdominal pain and diarrhea, improving the patient's quality of life. However, it may also lead to complications, such as nutrient malabsorption, since the ileum plays a crucial role in absorbing vitamins and minerals. Regular follow-up care is essential after surgery.
