Sutures and Wound Repair/ General Surgery (ABSA) Practice Test

What is a potential risk if the mesentery is not properly reapplicated after colon resection?

1. Increased blood loss

2. Infection risk

3. Bowel entrapment leading to hernia

4. Delayed wound healing

The correct answer is: Bowel entrapment leading to hernia

If the mesentery is not properly reapplicated after a colon resection, one significant risk is bowel entrapment leading to a hernia. The mesentery is the fold of tissue that attaches the intestines to the abdominal wall and contains blood vessels, nerves, and lymphatics. Proper reapplication is crucial to ensure that the intestines are securely positioned within the abdominal cavity. When the mesentery is inadequately reattached, sections of the bowel may not have sufficient support or may be allowed to move freely. This instability can lead to a situation where loops of the bowel become trapped outside of their normal anatomical position, potentially pushing through an opening in the abdominal wall or into a weak area, resulting in a hernia. This complication can lead to severe consequences, including bowel obstruction, ischemia, and subsequent need for reoperation. Thus, ensuring proper reapplication of the mesentery is essential for maintaining the integrity of the abdominal structure and function following surgery.
