Listen to pronunciation. (PEH-dih-kul …) A type of surgery used to rebuild the shape of the breast after a mastectomy. Tissue, including skin, fat, and muscle, is moved from one area of the body, such as the back or abdomen, to the chest to form a new breast mound.

What is Graham Omentopexy?

gastroenterology. A Graham patch is a surgical technique that is used to close duodenal perforations. A piece of omentum is used to cover the perforation. This patch is typically used for holes with a size of 5mm or less.

Is a pedicle flap a local flap?

Local (pedicled) flap: Tissue is freed and rotated or moved in some manner from an adjacent area to cover the defect, yet remains attached to the body at its base and has blood vessels that enter into the flap from the donor site.

What is omental flap surgery?

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.

What is the difference between free flap and pedicle flap?

When the TRAM flap is a pedicle flap, it remains attached to its blood supply, with the tissue surgically tunneled underneath the skin to the breast region. When the TRAM flap is a free flap, the tissue is detached and cut away from its blood supply before being transferred.
