What is a omental wrap?

Omental wrapping involves taking a piece of the omentum, a protective layer of fatty tissue that lines the abdominal cavity, and wrapping it around the anastomosis where two parts of the intestine were sutured together during a bowel surgery. This technique, also known as omentoplasty, aims to provide extra reinforcement and protection to the surgical site to prevent any potential leakage or dehiscence (splitting) of the sutures.

Here are a few reasons why omental wrapping is performed during bowel surgery:

1. Prevention of Anastomotic Leakage: The omentum, with its rich blood supply and fatty tissue, can act as a barrier to prevent any potential leaks from the sutured bowel segment. By wrapping the omentum around the anastomosis, the risk of leakage and subsequent complications is reduced.

2. Mechanical Support: The omentum provides additional physical support to the anastomosis. It helps to cover the suture line, strengthening the surgical site and preventing any internal disruption due to movement or strain in the abdomen.

3. Improved Healing: The omental tissue contains bioactive substances, growth factors, and immunologically active cells that can promote tissue regeneration and healing. By wrapping the omentum around the anastomosis, it enhances the healing process and reduces the risk of infection or complications.

4. Antibiotic Depot: The omentum can also serve as a depot for antibiotics. When administered locally during the surgery, antibiotics can be slowly released from the omentum, providing sustained antimicrobial protection to the surgical site.

Overall, omental wrapping is a commonly used technique in bowel surgery to enhance healing, prevent anastomotic leakage, and provide additional protection to the surgical site. It utilizes the natural healing properties of the omentum to promote a successful postoperative outcome.
