An omental "J" flap provides (1) a nonirradiated vascular pedicle flap to cover intestinal anastomoses and (2) vesicovaginal-rectovaginal fistula repairs to form a lid on the inlet of the true pelvis after exenteration and to form a cylinder for a neovagina.

2013年10月1日 · An omental pedicle flap is fashioned when the physician dissects a portion of the omentum from over the transverse colon. The freed portion of omentum is then rotated (leaving the main blood supply intact), placed into the pelvis to exclude to the small bowel or fill an intra-abdominal defect, and then sutured to the pelvic sidewall and/or ...

2011年11月8日 · Oncologic surgeries, including total pelvic exenteration and abdominoperineal resection, are the leading indications for pelvic reconstruction. The pedicle flaps most commonly used for pelvic reconstruction following these oncologic interventions are the vertical rectus abdominis myocutaneous flap (VRAM) and the omental pedicle flap.

The omental pedicled flap (based on the left gastroepiploic artery and vein) was wrapped around the prosthetic graft and filled the dead space from the left juxtarenal area. Wrapping prosthetic grafts with omentum to prevent postoperative graft infection has not yet been definitively proven to be effective in the long term.

During surgery the doctor may use a flap to repair an area where a mass, tumor or lesion has been removed. The flap tissue is used to cover and close a large incision or wound. pedicle flap is known as an “attached” flap because one side of the flap stays attached to its original blood supply (arteries and veins). No blood vessels are cut.

2018年11月12日 · Here we present a case where a pedicled omental flap was utilized to provide circumferential and buried coverage of an in-line ilio-femoral bypass graft well below the level of the inguinal ligament. The reach of the omentum was more than adequate, and the delicate nature of the flap provided excellent circumferential coverage of a cryo-vein ...

Omental pedicle flap was superior to muscle flap in reducing local recurrence and shortening postoperative hospital stay after OWT closure. However, mortality, morbidity and success rates were not influenced by the type of flap used for OWT closure.

2023年4月30日 · Omentum can be used as either a pedicled flap or free flap for the purpose of pelvic reconstruction. Pedicled flap is more popular among most surgeons as it does not need fine microvascular surgical technique, and it is very easy to harvest, not time-consuming, and hardly ever suffers an ischemic necrosis.

2019年10月14日 · Omental flaps are most useful for filling of dead space in the pelvic cavity and separation of the intra-abdominal contents from the perineum. When perineal skin replacement is necessary due to disease involvement or radiation injury, omental flap alone will likely not suffice.

Omental mobilization, transfer and buttressing of primary perineal repair following proctectomy reduces perineal wound morbidity with minimal additional operating time or flap-associated morbidity.
