What are benign tumors of the mesentery and omentum?
Benign tumors of the mesentery and omentum are rare and are often found incidentally on ultrasound or computed tomography.
They may include:
- lipomas
- fibromas
- leiomyomas
- benign vascular tumors
- lymphangiomas
- other rare mesenchymal lesions
As they grow, they may cause:
- abdominal pain
- a feeling of pressure
- compression of the bowel
- bowel obstruction
- bleeding or other complications
Our approach
At MSI, tumors of the mesentery and omentum are treated in line with modern principles of abdominal and oncological surgery.
Before surgery, a comprehensive examination is carried out, which may include:
- ultrasound
- computed tomography
- magnetic resonance imaging
- laboratory tests
When technically feasible, we aim to remove these tumors laparoscopically.
For large tumors, a difficult anatomical location, or close contact with major vessels, open surgery may be recommended.
The key principle is *complete (R0) removal of the lesion* while preserving as much of the bowel and mesenteric vessels as possible.
Postoperative treatment follows the principles of *ERAS (Enhanced Recovery After Surgery)*.
When is surgery needed?
Surgery is performed for:
- symptomatic lesions
- tumor growth
- pain
- compression of the bowel or other organs
- a lesion of uncertain nature
- suspected malignancy
Indications for surgery
Surgery is recommended for:
- clinical symptoms
- progressive tumor growth
- a large lesion
- an uncertain diagnosis based on examination results
- a risk of complications
How is the operation performed?
The procedure is performed under general anesthesia.
After the abdominal cavity is explored, the tumor is mobilized and removed completely, together with adjacent tissues if necessary.
Special attention is paid to preserving:
- the major mesenteric vessels
- the blood supply of the bowel
- neighboring organs
If the tumor has grown into the bowel or cannot be separated safely, a segmental bowel resection may be necessary.
All removed lesions are sent for histopathological examination.
Advantages of laparoscopic surgery
- Minimal surgical trauma
- Less postoperative pain
- Fast recovery
- Lower risk of wound complications
- Shorter hospital stay
- Better cosmetic result
Recovery after surgery
Postoperative treatment follows *ERAS* principles.
Most patients quickly return to physical activity and their normal lifestyle. The length of the hospital stay depends on the complexity and extent of the operation.
Our advantages
- Extensive experience in laparoscopic abdominal surgery
- A commitment to laparoscopic surgery
- Maximum preservation of the bowel and its blood supply
- Individual planning of the extent of surgery
- Routine histopathological examination of all removed lesions
- Enhanced recovery program (ERAS)
Frequently Asked Questions
Not always. Small asymptomatic lesions can be monitored. Surgery is recommended if the tumor grows, symptoms appear, or malignancy cannot be reliably ruled out.
Yes. In most cases, we aim to remove the lesion laparoscopically.
Yes. If the tumor is firmly attached to the mesentery, vessels, or bowel wall, resection of the corresponding bowel segment may be needed to remove it completely.
Not always. CT or MRI findings can only suggest the nature of the lesion. The final diagnosis is made after histopathological examination.
After complete removal of a benign lesion, the risk of recurrence is minimal but depends on the histological type of the tumor.
