retroperitoneal tumor
Introduction
Introduction to retroperitoneal tumors The retroperitoneal tumor mainly comes from the fat in the retroperitoneal space, loose connective tissue, muscle, fascia, blood vessels, nerves, lymphoid tissue, etc., and does not include the various organs (kidney, pancreas, adrenal gland and ureter, etc.) in the retroperitoneal space. Tumor. Retroperitoneal tumors are benign and malignant. Malignant tumors account for about 60-80%. Commonly, there are liposarcoma, fibrosarcoma, neurofibrosarcoma and malignant lymphoma. Fibroids and teratomas are common in benign tumors. In general, retroperitoneal tumors, cystic people are often benign, and most of them are malignant. basic knowledge The proportion of sickness: 0.004% - 0.009% Susceptible people: no specific population Mode of infection: non-infectious Complications: lymphoma
Cause
Cause of retroperitoneal tumor
Cause of disease:
The etiology is unclear, and the retroperitoneal tumors are benign and malignant. The malignant tumors account for 60-80%. Commonly, there are liposarcoma, fibrosarcoma, neurofibrosarcoma and malignant lymphoma. The benign tumors are fibroids. Fetal tumors are common. In general, retroperitoneal tumors, cystic people are often benign, and most of them are malignant.
Prevention
Retroperitoneal tumor prevention
The retroperitoneal tumor mainly originates from the retroperitoneal space, and the site is deep and early. It is asymptomatic. With the development of the tumor, the waist and abdomen are painful or the organ tissue is pressed and pressed. Therefore, there is a dull and painful discomfort in the waist and abdomen. Should be alert to this disease, for early detection, early treatment, retroperitoneal tumors are mostly malignant, rapid development, poor prognosis, do not indiscriminately take medicine, delay the disease, the current treatment of this disease is still based on surgery, supplemented with chemotherapy or Radiotherapy, non-general clinic can solve, hope that patients suspected of this disease, to the conditional hospital for treatment, to ensure good results.
Complication
Retroperitoneal tumor complications Complications lymphoma
The prognosis of malignant tumors is very poor. The recurrence rate after resection can be as high as 30%-50%, and the degree of malignancy increases with recurrence. The 5-year survival rate after resection is less than 10%. The prognosis after complete resection of benign tumors is good, but There are also some tumors that are prone to recurrence and malignant transformation, such as retroperitoneal lipoma, leiomyoma, etc. Lymphoma and neuroblastoma occasionally cured by radiotherapy.
Symptom
Retroperitoneal tumor symptoms Common symptoms Abdominal muscles Abdominal pain Ascites bloating fatigue Low heat waist muscle shadow disappears
1. Abdominal mass: The area of the retroperitoneal tumor is deep, and it is asymptomatic in the early stage. When the tumor develops to a certain extent, the abdominal mass is found when the organ is compressed and the pain is caused. Benign people grow slowly, malignant people develop rapidly, and the mass is more than one side.
2. Symptoms of compression: When the gastrointestinal tract is compressed, there may be nausea, vomiting and feeling of fullness; when the rectum is compressed, there may be an increase in the number of stools and an anal swelling, and even stool deformation and difficulty in defecation; common symptoms of urinary compression are : Frequent urination, urgency, difficulty urinating or hematuria, ureteral compression can cause hydronephrosis, vascular edema of lower extremities.
3. Pain: Pain in the retroperitoneal tumor is due to increased tension of the capsule or compression of the irritating nerve, which is characterized by low back pain, perineal pain or lower limb pain.
4. Systemic symptoms: loss of weight, fatigue, loss of food and drink, and even cachexia. A small number of tumors with endocrine function may have corresponding symptoms.
Examine
Examination of retroperitoneal tumors
1. The mass is deep and fixed. When the chest and knee are examined, the mass is fixed in the posterior peritoneum without sagging movement.
2. B-ultrasound, CT or retroperitoneal angiography suggest that the mass is located behind the retroperitoneum.
Diagnosis
Diagnostic diagnosis of retroperitoneal tumor
B-mode ultrasonography can also find posterior peritoneal tumors and enlarged lymph nodes, but intestinal gas interference makes the diagnosis difficult to be accurate, but the diagnosis or exclusion of abdominal aortic aneurysm is more reliable, biopsy or follow-up of tumor under B-mode ultrasound guidance Changes after chemotherapy are very useful. Ultrasound examination alone is not easy to distinguish post-peritoneal tumors from abscesses or hematoma. Cystic tumors are easily confused with cysts, inflammatory or traumatic hematoma, under B-mode ultrasound or CT guidance. Percutaneous fine needle attractive biopsy has great significance for diagnosis, and the diagnosis rate is about 80%.
