Peritoneal tumor

Introduction to peritoneal tumor A tumor that occurs in the peritoneum. Primary peritoneal tumors are rare. Secondary tumors can be derived from ovarian and embryonal carcinoma, mesenteric or intestinal wall lymphosarcoma, and metastasized from the abdominal or any other organ to the peritoneum. After the emergence of secondary peritoneal cancer, ascites and multiple, nodular masses can be produced. Sometimes abdominal palpation or rectal examination can reach the cancerous nodules at the pelvic floor. In the late stage, children with abdominal distension caused by a large amount of ascites, such as weight loss, fatigue and anemia, etc., can be obtained by abdominal puncture for bloody ascites, smear to find cancer cells can help diagnose, the prognosis is sinister. Peritoneal tumors are mainly derived from fat in the peritoneal space, loose connective tissue, fascia, muscle, blood vessels, nerve tissue, lymphoid tissue and embryonic residual tissue. 2/3 is a malignant tumor. Only early treatment of primary cancer can prevent peritoneal cancer. For the treatment of secondary peritoneal cancer, chemotherapy, radiotherapy and general supportive therapy can be used. basic knowledge The proportion of illness: 0.07%--0.2% Susceptible people: no specific population Mode of infection: non-infectious Complications: anemia, ascites, jaundice

The cause of peritoneal tumor

Peritoneal tumors are mainly derived from fat in the peritoneal space, loose connective tissue, fascia, muscle, blood vessels, nerve tissue, lymphoid tissue and embryonic residual tissue. 2/3 is a malignant tumor.

Benign tumor

Lipoma, fibroids, ganglioneuroma, cystic teratoma, and chemoreceptor tumors.

2. Malignant tumor

Lymphosarcoma, liposarcoma, fibrosarcoma, malignant schwannomas and malignant teratoma.

Peritoneal tumor prevention

Early diagnosis and early treatment of various types of cancer patients are the most important preventive measures.

Peritoneal tumor prevention diet with comprehensive nutrition, high protein, high vitamin, low fat and low salt diet, eat less or not spicy stimulation, fat and greasy, barbecue, pickled and other foods, usually eat regularly quantitative, reasonable nutrition principle . Eat more food such as fish, lean meat, eggs, soy products, mushrooms, jujube and so on.

Check and participate in outdoor exercise to increase your immunity, participate in physical examinations on a regular basis, and find out the condition and timely treatment.

Peritoneal tumor complications Complications, anemia, ascites, jaundice

Can be combined with the following conditions:

Malignant tumors grow to a certain period of time, can appear weight loss, fatigue, reduction, anemia, fever, ascites, jaundice, and even cachexia.

Peritoneal tumor symptoms Common symptoms Abdominal mass tumor block compression low back pain Appetite loss weight loss

1. Abdominal mass: The retroperitoneal tumor is deep and early asymptomatic. When the tumor develops to a certain extent, it produces oppressed organs and pain. It is found that the benign mass of the abdominal mass grows slowly, the malignant develops rapidly, and the mass is more partial. One side.

2, compression symptoms: gastrointestinal tract compression may have nausea and vomiting and fullness, when the rectum is compressed, there may be increased stool frequency and anal swelling. Even stool deformation and difficulty in defecation, common symptoms of urinary compression are: urinary frequency urinary urgency or urinary ureteral pressure can cause hydronephrosis. When the blood vessels are compressed, the lower limbs are edematous.

3. Pain: Pain in the retroperitoneal tumor is due to increased tension of the capsule or compression to invade the nerve. It is characterized by low back pain and genital pain or lower limb pain.

4, systemic symptoms: the appearance of weight loss, fatigue, loss of food and even cachexia. A small number of tumors with endocrine function may have corresponding symptoms.

Examination of peritoneal tumors

The following checks are possible to confirm the diagnosis:

1. The mass is deep and fixed. When the chest and knee are examined, the mass is fixed in the peritoneum without sagging movement.

2. B-ultrasound, CT or retroperitoneal angiography suggest that the mass is located in the peritoneum. Generally used only for malignant tumors.

3. Intravenous urography, abdominal ultrasound, CT scan showed that the lesion was in the renal parenchyma. Renal radionuclide scanning can also help with diagnosis. Wilms tumor is a common tumor in children, and the vast majority occur in 2 to 4 years old. The tumor is located on one side of the waist and does not exceed the midline of the abdomen, often accompanied by fever. Half of the children had elevated blood pressure and advanced anemia and cachexia. Ultrasound examination, CT scan showed substantial lesions in the kidney, and intravenous urography showed a substantial lesion in the kidney or no development.

Diagnosis and diagnosis of peritoneal tumor

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

1. Kidney tumor: Kidney tumor is more common in malignancy, less benign and less accessible to the abdomen. Adults are more common with kidney cancer, and they are more likely to be over 40 years old. The tumor is located at the waist and often has gross or microscopic hematuria. Patients with advanced disease often have fever, anemia, and weight loss. Intravenous urography, abdominal ultrasound, and CT scan showed lesions in the renal parenchyma. Renal radionuclide scanning can also help with diagnosis.

Wilms tumor is a common tumor in children, and the vast majority occur in 2 to 4 years old. The tumor is located on one side of the waist and does not exceed the midline of the abdomen, often accompanied by fever. Half of the children had elevated blood pressure and advanced anemia and cachexia. Ultrasound examination, CT scan showed substantial lesions in the kidney, and intravenous urography showed a substantial lesion in the kidney or no development.

2. Hydronephrosis: Congenital hydronephrosis in children is caused by congenital upper urinary tract obstruction, which occurs in children over 5 years old. The tumor was located in the lateral abdomen, cystic, and the abdominal wall was thin and the light transmission test was positive. X-ray films showed enlarged kidney shadows and sometimes calcification spots. Ultrasonography, excretory urography, radionuclide kidney maps, and kidney scans are valuable for diagnosis. Adult hydronephrosis has a long history and may have a history of hematuria and low back pain. Some patients have a history of colic due to ureteral stones, or have a history of secondary infection. Excretory urography can be seen in the enlargement of the renal pelvis and renal pelvis, but advanced cases may not be developed. Congenital or adult hydronephrosis is sometimes temporarily relieved due to obstruction and has a history of sudden tumor shrinkage, which is a unique symptom of this disease.

3. Polycystic kidney disease: a congenital disease caused by a disorder in the connection between the renal tubules and the collecting duct during the embryonic period. Infant type died within 1 year of age. Adults are mostly bilateral, with slow onset, often appearing around 40 years old, and often accompanied by other organs such as liver and lung cysts. In addition to a lump in the waist, there may be a history of hematuria, urinary tract infection, high blood pressure, and side abdomen or lumbar pain. Uremia can occur in the advanced stage. Urinary angiography showed signs of elongation, deformation, etc. of the renal pelvis and renal pelvis. There were multiple liquid level segments in the ultrasound examination of the kidney area. Radionuclide scans show a large area of radioactive defect in the kidney.

4. Pancreatic cyst: The disease should be differentiated from the retroperitoneal tumor located in the upper abdomen, and the clinical pseudo-pancreatic cyst is more common. The disease has a long course. In the past, there were many cases of acute pancreatitis or abdominal injury. The tumor was located on the left side of the upper abdomen. The palpation revealed that the tumor was round or elliptical, the boundary was unclear, and sometimes the capsule was sexy and inactive. May be accompanied by symptoms of peripheral organs such as poor appetite and vomiting. Ultrasound examination showed liquid level. X-ray examination showed that there may be calcified plaque in the pancreas. The barium meal examination is helpful for the diagnosis of this disease. It can be found that the stomach is pressed and moved forward, the duodenum is enlarged and the transverse colon is upward or Shift down.

5. Pancreatic body cancer: This disease is characterized by abdominal pain. Abdominal pain is located in the upper abdomen and radiates to the lower back, chest, shoulders and ribs. It is mostly persistent dull pain and can not be relieved. It is aggravated when lying on the back, especially at night, often forcing the patient to bend down or bend down to the side. Often accompanied by loss of appetite, diarrhea, weight loss and urine sugar positive. The upper abdomen or the upper left abdomen touched the tumor mostly in the late stage. Retrograde biliary, pancreatic angiography, and CT are helpful in the diagnosis of this disease.

6. Colon cancer: This disease is mainly characterized by changes in stool traits and bowel habits, and diagnosis is not difficult. However, a small number of patients often see a diagnosis of abdominal mass. When the ascending colon or descending colon cancer or hepatic flexion and splenic colon cancer invade the surrounding tissue, the tumor is relatively fixed. If the medical history does not have any changes in bowel traits and bowel habits, then it should be done. Enema examination or fiber colonoscopy can be used to collect tissue specimens for pathological examination. In addition, a small number of patients have no history of blood in the stool, but those who have been positive for fecal occult blood tests should also consider the possibility of this disease. The above special examination methods should be carried out to avoid misdiagnosis.

7. Tuberculous peritonitis: The disease may sometimes touch the tumor in the abdomen, and sometimes it is fixed with the posterior wall of the abdomen, the intestine and the mesentery, and is easily confused with the retroperitoneal tumor. However, this disease is more common in young women, with clinical manifestations of chronic tuberculosis, tuberculosis can be found in other parts of the body; and the abdominal masses of this disease often have multiple characteristics of different sizes and shapes, often with unclear borders, sometimes accompanied by There are varying degrees of intestinal obstruction. Gastrointestinal angiography can be used to understand the presence or absence of intestinal tuberculosis. Laparoscopy is helpful for diagnosis, but it is often difficult to achieve adhesion between the intestine and the abdominal wall. Exploratory laparotomy should be performed when the diagnosis is suspicious.

8. Abdominal aortic aneurysm: This disease is rare, mostly caused by atherosclerosis or abdominal injury. Before the tumor is located in the spine, there is an expansive pulsation, which can be tender. The tumor can sometimes touch the systolic tremor and hear the squeaky murmur. Patients often have varying degrees of pain. If the vertebral body is pressed, there may be pain in the lower back. X-ray films (positive lateral slices) can sometimes detect linear calcification of the tumor wall. Abdominal aortic angiography or MRI can be performed in suspicious cases to confirm the diagnosis.

9. Cold abscess: The cold abscess formed by the lower thoracic and lumbar tuberculosis can form a retroperitoneal mass, which should be differentiated from the retroperitoneal tumor. Patients often have a history of low back pain, the spine can be deformed, and the cold abscess is mostly located on the side of the abdomen. The primary tuberculosis lesion can be found on the radiograph of the spine.
