Complications arising from omental patch placement or omental pedicle grafting are rare and fairly inconsequential. The most
common complication is partial necrosis of the omentum, which is usually the result of excessive tension or strangulation
of a pedicle.2,4 Excessive or improper handling of the omentum during surgery may also lead to desiccation. Desiccation can be prevented
by frequently moistening the omentum during the procedure or by keeping it wrapped in saline-soaked laparotomy pads. Intestinal
entrapment by omental adhesions or tears can cause strangulation or torsion of the bowel in animals that have not undergone
omentalization; a similar problem could occur after omental patch placement.14,15 We know of two animals that developed intestinal obstruction after omentum, which had been wrapped 360 degrees around their
intestines, hypertrophied. Consequently, encircling the intestines with a single flap of omentum is not recommended.
