What is omentum flap?

What is omentum flap?

The greater omentum is a large peritoneal fold consisting of connective tissue, fat and lymphatics. It is well vascularized with large feeding arteries and draining veins. Because harvesting requires laparotomy, this flap is used infrequently.

What is omental flap intra abdominal?

Add-on code 49905 Omental flap, intra-abdominal (List separately in addition to code for primary procedure) is reported when an omental pedicle flap is created and positioned to fill or correct an intra-abdominal defect, such as an enterocele or “dead space,” resulting from a colovaginal or colovesical repair.

What is a free omental flap?

The omentum free flap has been considered a salvage flap due to concerns of donor site morbidity associated with a laparotomy. Hultman et al.12 reported 135 omentum flaps (64 pedicled and 71 free tissue transfer) for complex extraperitoneal wounds over a 25-year period utilizing an open, laparotomy technique.

Can omentum be removed?

An omentectomy is the surgical removal of all or part of the omentum. The omentum is a fold of fatty tissue inside the abdomen that surrounds the stomach, large intestine and other abdominal organs. This tissue contains the lymph nodes, lymph vessels, nerves and blood vessels. There are two types of omentectomy.

What is omental bursa?

Anatomical terminology The lesser sac, also known as the omental bursa, is the cavity in the abdomen that is formed by the lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow.

What is the difference between omentum and peritoneum?

The peritoneum is a serous membrane that lines the abdomino-pelvic cavity and supports and protects abdominal organs. Omentum, on the other hand, is a fold of the peritoneum. Omenta form connections between the stomach and the duodenum. Peritoneum divides further as the visceral peritoneum and the parietal peritoneum.

What is a free omental flap with microvascular anastomosis?

The omentum free flap also provides a long vascular pedicle (15 cm or longer) that facilitates microvascular anastomosis especially when recipient vessels may be relatively distant in the neck.

What are the side effects of having your omentum removed?

What are the risks of omentectomy?

• Pain.
• Lymphedema – buildup of fluid caused by lymph-vessel blockage.
• Nerve damage that could be permanent.

How long does it take to recover from omentum surgery?

Most women will stay in the hospital for 3 to 7 days after the operation and can resume their usual activities within 4 to 6 weeks.

How do I get to omental bursa?

The omental bursa can be surgically entered through the hepatogastric ligament, gastrocolic ligament, gastrosplenic ligament or through the transverse mesocolon. Anatomical boundaries of the omental bursa could be clearly identified, and new anatomical landmarks were described (gastro-omental folds).

Where is omental bursa?

The lesser sac, also known as the omental bursa, is the cavity in the abdomen that is formed by the lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow.

Does the omentum grow back?

After fusing with the injured tissue, the activated omentum brings about vascularization, debridment, hemostasis, healing, and regeneration of the tissue. These unique biological properties of the omentum have long been noted and applied in surgical practice.

What is the difference between omental flap and muscle flap?

An omental flap is theoretically preferable to muscle flaps in these circumstances due to its superior resistance to infection and because it allows a better filling of the deepest mediastinal recesses, thus avoiding the persistence of an empty space [1-3]. On the other hand, muscle flaps are more commonly used for the lower surgical trauma.

What is the role of vascularization in the treatment of mediastinitis?

The use of vascularized tissue is needed for infection control, while flail chest is generally a minor problem for the mediastinal stiffness secondary to post inflammatory fibrosis.

How is mediastinal debridement performed with Volkmann’s Spoon?

An accurate mediastinal debridement (Figure 1D) was performed with Volkmann’s spoon. The omental flap was finally gently placed to fill the defect, fixed with interrupted sutures to the wound edges (Figure 2B).
