What is the main purpose of carefully reapplying the mesentery after colon resection?

Facilitating nutrient absorption
Preventing internal hernia with bowel entrapment
Reducing postoperative pain
Enhancing blood flow to the anastomosis

The correct answer is: Preventing internal hernia with bowel entrapment

The main purpose of carefully reapplying the mesentery after colon resection is to prevent internal hernia with bowel entrapment. The mesentery is the fold of tissue that attaches the intestines to the abdominal wall and contains the blood vessels, lymphatics, and nerves supplying the bowel. When performing a colon resection, if the mesentery is not properly repositioned or secured, loops of bowel may become free, potentially leading to an internal hernia. This condition can put the bowel at risk for strangulation, ischemia, and subsequent necrosis due to compromised blood supply. While other factors such as nutrient absorption, postoperative pain, and blood flow might be influenced by the surgical technique and outcomes, the primary concern immediately after a resection is to ensure the integrity of the bowel and prevent complications like an internal hernia. Proper reapplication of the mesentery helps to maintain the anatomical relationships and stability of the bowel, thereby directly addressing this critical issue.
