The deep inferior epigastric artery perforator or DIEP flap is a microsurgical technique in which blood vessels, skin and fat are taken from the lower abdomen and used to reconstruct the breast(s).

Epigastric pain affects the middle of the upper abdomen, just below the ribcage. It is common during pregnancy. Other causes include indigestion, acid reflux and GERD, peptic ulcer disease, and more.
