Our approach
Every cystic lesion of the omentum requires careful assessment.
At MSI, we determine the origin of the cyst, assess the risk of complications, and rule out other abdominal diseases, including tumors. Whenever possible, we give preference to laparoscopic removal, which minimizes tissue trauma and ensures fast recovery.
What are omental cysts?
An omental cyst is a fluid-filled cavity located in the greater or lesser omentum.
They may be:
- of lymphatic origin
- mesothelial
- congenital
- post-traumatic
- inflammatory
- pseudocysts
Most omental cysts are benign.
Why do omental cysts develop?
The causes can vary.
Most often these are:
- congenital abnormalities of the lymphatic vessels
- abnormal embryonic development
- previous abdominal injuries
- inflammatory processes
- impaired lymphatic drainage
In a significant proportion of patients, the exact cause cannot be determined.
Symptoms
Small cysts usually cause no symptoms.
As they enlarge, the following may occur:
- abdominal pain or discomfort
- a feeling of fullness
- a palpable mass
- bloating
- nausea
- feeling full quickly
In rare cases, the following are possible:
- torsion of the cyst
- bleeding
- infection
- rupture of the cyst
- bowel obstruction due to compression of the bowel
When to see a doctor
A consultation is recommended if:
- an omental cyst has been found on ultrasound, CT, or MRI
- the lesion is growing
- you have abdominal pain or discomfort
- the nature of the lesion cannot be determined with certainty
- the indications for surgical treatment need to be determined
How is the diagnosis made?
The following are used to establish the diagnosis:
- consultation with a surgeon
- ultrasound examination
- contrast-enhanced computed tomography
- magnetic resonance imaging
- laboratory tests
- histological examination after surgery
How are omental cysts treated?
The treatment strategy depends on the size, symptoms, and nature of the lesion.
Options may include:
- follow-up monitoring in carefully selected patients
- laparoscopic removal of the cyst
- open surgery for large or technically complex lesions
Puncture or drainage of the cyst is not a definitive treatment and carries a high risk of recurrence.
Surgical treatment
The main treatment for symptomatic or uncertain omental cysts is complete removal.
At MSI we perform:
- laparoscopic removal of omental cysts
- resection of part of the greater or lesser omentum together with the cyst
- open surgery for large lesions
- removal of cysts of uncertain origin with mandatory histological examination
The main goal of surgery is complete removal of the lesion without damaging it and with preservation of the surrounding organs.
Recovery after treatment
After laparoscopic cyst removal, most patients quickly return to normal life.
At MSI, ERAS protocols are used to shorten the hospital stay, reduce postoperative pain, and speed up rehabilitation.
Why choose MSI
- Experience in treating rare abdominal lesions
- Specialization in laparoscopic abdominal surgery
- The least invasive approach possible
- Individual treatment planning
- Enhanced recovery protocols (ERAS)
- Mandatory histological examination of all removed lesions
Frequently Asked Questions
No. In most cases, omental cysts are benign. The final diagnosis is made after histological examination of the removed lesion.
Not always. Small asymptomatic cysts can be monitored. Surgery is recommended when symptoms appear, the cyst grows, or a tumor cannot be ruled out.
In most cases, yes. Laparoscopic removal is the method of choice thanks to less tissue trauma, faster recovery, and a better cosmetic result.
After complete removal, the risk of recurrence is minimal. That is why radical excision of the cyst is preferred over puncture or drainage.
The outlook is very favorable. After complete removal of the cyst, most patients recover fully and return to their normal lifestyle, and the risk of the disease recurring is low.
