A colectomy, specifically a partial colectomy with the removal of the terminal ileum and subsequent ileocolostomy, is a surgical procedure performed to address various conditions affecting the colon and terminal ileum. This operation typically involves making a midline incision in the abdomen to gain access to the abdominal cavity. During the procedure, the surgeon inspects the abdominal organs and identifies the diseased segment of the colon that requires removal. The procedure entails mobilizing the affected portion of the colon along with a segment of the terminal ileum, which is the last part of the small intestine. The surgeon then clamps the colon and terminal ileum above and below the area designated for transection, allowing for the diseased sections to be excised. Following the removal, an ileocolostomy is performed, which involves connecting the remaining segment of the terminal ileum to the remaining healthy segment of the colon in an end-to-end configuration. This connection is crucial for restoring continuity of the gastrointestinal tract. After the surgical steps are completed, drains may be placed to prevent fluid accumulation, and the abdominal incisions are meticulously closed to promote healing.
