[Greater omentum flap: Treatment of chronic wounds and seroma: About a case]

Cicatricial complications after abdominal or pelvic surgery are more frequent in obese patients. In this case, infection, seroma and delays in scarring can be extremely difficult to treat. The objective of this technical note is to present an original case of an obese patient operated nine years ago of a hysterectomy by laparotomy and chronically presenting a non-resolving septic seroma despite multiple surgical procedures whose healing could be obtained by a flap of greater omentum.

The ideal is to carry out this intervention in a double team with a digestive surgeon in case of intra-abdominal visceral or vascular wound during dissection. The greater omentum flap was raised in a conventional manner over the gastroepiploic artery. A sufficiently wide orifice should be left at the level of the abdominal aponeurosis in order to avoid any compression of the pedicle. Finally, the flap must be spread over the whole surface of the detachment and fixed to the anterior aponeurosis.

Reliability and vascular and lymphatic richness make the greater omentum flap a very effective method in chronic wound cases associated with important seroma. The scarring obtained in the clinical case presented thus highlights the specific qualities of this flap.
