What causes omentum inflammation?
What causes omentum inflammation?
Primary causes, or contributing factors, to omental torsion encompass obesity, local trauma, heavy food intake, coughing, sudden body movements, laxative use and hyperperistalsis.
What causes a twisted omentum?
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.
What is omental necrosis?
rare. Deaths. very rare. Omental infarction, or omental torsion, is an acute vascular disorder which compromises tissue of the greater omentum—the largest peritoneal fold in the abdomen.
What is the treatment for omental infarction?
Conclusions: Omental infarction should be considered in the differential diagnosis of the acute surgical abdomen. Laparoscopic partial omentectomy is a safe and effective treatment which may lead to improved outcomes when conservative therapy fails.
What causes infarcted omentum?
Omental infarction is caused by a compromise to the blood supply by either torsion or spontaneous venous thrombosis. Clinically it is often indistinguishable from acute cholecystitis and appendicitis.
Can omentum cause pain?
Omental torsion is a cause of acute abdominal pain and sometimes mimics acute appendicitis in its presentation. We present a case of a 14-yr-old boy who presented with acute abdomen with symptoms mimicking acute appendicitis.
What is omental ischemia?
Omental ischemia is a benign self-limiting disorder which in unremitting cases could cause ischemic necrosis of the involved part of the omentum and in intermittent cases may be a rare cause of recurrent abdominal pain [1].
Can omental infarction be cured?
Conclusion: Omental infarction is a relatively rare disease characterized by acute abdomen. Nonsevere cases may be successfully treated without antibiotics.
What causes omental thickening?
In radiology, omental cake is sign indicative of an abnormally thickened greater omentum. It refers to infiltration of the omental fat by material of soft-tissue density. Typically, it is caused by infiltration of metastatic tumours arising from the stomach, ovary, or colon.
How is omental infarction diagnosed?
Although it remains the second choice of imaging modality, ultrasound can equally diagnose omental infarction through the appearance of non-compressible and increased echogenic mass in the omental fat [9]. There are two approaches to managing omental infarction: conservative and laparoscopic excision.
What is Omental infarction and what causes it?
Omental infarction is rare cause of acute abdomen which occurs because of focal torsion or lack of blood flow to a portion of the omentum 1). Omental infarction signs and symptoms can mimic other acute intra-abdominal conditions like appendicitis and cholecystitis.
Can the omentum infarct without torsion?
The omentum may infarct without torsion, and this is called as primary idiopathic segmental infarction 16). Both primary omental infarction and infarction secondary to torsion have been reported in children 17). Precipitating factors are thought to include trauma, overexertion, bifid omentum, overeating and coughing 18).
What causes segmental infarction of the greater omentum?
Primary omental infarction occurs spontaneously without any immediate aetiology and has consequently been named idiopathic segmental infarction of the greater omentum (ISIGO). Anatomical variations such as malformation, local variations in fat distribution, and redundant omental veins may predispose patients to ISIGO [4].
How is Omental infarction diagnosed in appendicitis?
Historically, omental infarction was diagnosed only intraoperatively during surgery for presumed appendicitis or other causes of acute abdomen. But with the increase in the use of imaging, especially abdominal computed tomography (CT) scan in the work-up for acute abdomen, more cases of omental infarction are being diagnosed preoperatively 9).
