Duodenectomy is the surgical removal of a portion of the duodenum, typically performed to treat cancers, benign tumors, or conditions like Crohn's disease or severe trauma. The duodenum is a vital part of the digestive system that connects the stomach to the small intestine, so careful planning is required for the surgery.

The procedure often involves resection of the affected section and reattachment of the remaining duodenum to the stomach or small intestine. If a tumor is present, nearby tissues or lymph nodes may also need to be removed.

Postoperative care includes monitoring for complications like infection, digestive disturbances, and managing any nutritional deficiencies. Patients may require a modified diet to allow the digestive system to adjust.

Duodenectomy is a crucial surgery for patients with tumors or severe diseases affecting the duodenum, and it offers the potential for improved outcomes when performed at an early stage.
