What is omental hernia?
A double omental hernia denotes herniation of the small bowel through an opening in the gastrocolic omentum and exits through the gastrohepatic omentum, representing an extremely rare cause for small bowel obstruction.
Can omental caking be benign?
Background. Omental cakes typically are associated with ovarian carcinoma, as this is the most common malignant aetiology. Nonetheless, numerous other neoplasms, as well as infectious and benign processes, can produce omental cakes.
Can nodules in omentum be benign?
If the OS was ≤5, the omental lesion was considered to be benign, with a malignant rate of 0%. If the omentum is inflamed, patients often have abdominal pain, fever, and other symptoms.
What causes omental caking?
Typically, it is caused by infiltration of metastatic tumours arising from the stomach, ovary, or colon. It can also result from tuberculous peritonitis. Another cause is lymphoma, in which omental caking is usually associated lymphadenopathy.
What does omental cake mean?
Omental cake refers to infiltration of the omental fat by material of soft-tissue density. The appearances refer to the contiguous omental mass simulating the top of a cake. Masses on the peritoneal surfaces and malignant ascites may also be present.
Does omentum contain lymph nodes?
The greater omentum contains groups of lymph nodes (level 4ab along the left gastroepiploic vessels and level 4d along the right gastroepiploic vessels) and lymphatic ducts for adequate drainage, which makes GOLF a good alternative choice for donor lymph node transfer.
What does thickening of the omentum mean?
INTRODUCTION Omental thickening or “caking” is a radiologic sign that frequently indicates advanced peritoneal disease. 1 It may be secondary to malignant, infectious, or inflammatory eti- ologies. Notably, the association between omental caking and ovarian cancer has been well established.
Can peritoneal nodules be non cancerous?
Benign cystic mesothelioma (BCM) is a very rare disease characterized by proliferative lesions of the peritoneal mesothelial cells mainly in the pelvic or abdominal cavity. However, it can also develop in the pleura, pericardium, tunica vaginalis, and spermatic cord [1].
Is a omental hernia serious?
The lesser omental hernia is a rare form of intestinal hernia. However, it is a severe clinical condition and can result in intestinal obstruction and other life-threatening complications [1, 2].
Can omentum be removed?
An omentectomy is the surgical removal of all or part of the omentum. The omentum is a fold of fatty tissue inside the abdomen that surrounds the stomach, large intestine and other abdominal organs.
What is omental metastasis?
Cancer cells that have broken away from the ovary like to implant and grow there—this is known as omental metastasis. The omentum also has a rich supply of lymphatic or immune areas known as “milky spots.”2
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.
