What is omental mass?
An omental cake arises when these nodules coalesce to form a diffusely thickened mass and replace the normal fat (Fig. 3b) [6]. Depending on the cause of the omental cake and the extent of intraperitoneal disease, ascites may be an accompanying feature.
What is omentum torsion?
Omental torsion is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised. Although it is rarely diagnosed preoperatively, knowledge of this entity is important to the surgeon because it mimics the common causes of acute surgical abdomen.
Can omentum cause pain?
INTRODUCTION. Torsion of the greater omentum is a rare, benign cause of acute abdominal pain, caused by twisting of the omentum around a pivotal point, usually in a clockwise direction [1].
What causes omental torsion?
Secondary omental torsion is associated with a number of pre-existing conditions most common among them is inguinal hernia, other causes include tumours, cysts, internal or external herniation, foci of intra-abdominal inflammation and postsurgical wound or scarring.
Does your omentum grow back?
As the omentum becomes activated, the milky spots (rather than the adipose tissue) become reactive and expand. After fusing with the injured tissue, the activated omentum brings about vascularization, debridment, hemostasis, healing, and regeneration of the tissue.
What is an omental biopsy?
An omental biopsy involves inserting a needle through the skin to take a sample of the omentum. Local anaesthetic is used to numb the skin. The radiologist uses an ultrasound scan to accurately direct the needle into the area that needs to be sampled.
What happens when you have your omentum removed?
Removal of the omentum impairs peritoneal defence mechanisms[3]. In experimental peritonitis, omentectomy has been found to reduce survival[40], and influence a number of peritoneal defence mechanisms[41].
Can omentum grow back?
What are the side effects of having your omentum removed?
What are the risks of omentectomy?
- Pain.
- Lymphedema – buildup of fluid caused by lymph-vessel blockage.
- Nerve damage that could be permanent.
