What is the primary reason for using warm irrigation after a right hemicolectomy?

The primary reason for using warm irrigation after a right hemicolectomy is to aid visual inspection for leakage. During this surgical procedure, the surgeon creates reconnections between the intestines, and it is crucial to confirm that these anastomoses are intact and not leaking. Warm irrigation helps to clear any blood, debris, or other fluids that might obscure the surgical field, making it easier for the surgeon to visually assess the integrity of these connections. This step is necessary to prevent complications such as anastomotic leaks, which can lead to serious postoperative issues.

While maintaining core body temperature, cleaning out the area, and eliminating microbes are important considerations in surgical practice, they are secondary to ensuring that the surgical site is clear and allows for a thorough inspection of the anastomoses to ensure they are secure and functioning as intended.
