Retroperitoneal tumors

　　Etiology of retroperitoneal tumors: The etiology is unclear. Retroperitoneal tumors are divided into two major categories: benign and malignant. Malignant tumors account for about 60-80% of all cases, common ones include liposarcoma, fibrosarcoma, neurofibrosarcoma, and malignant lymphoma; benign tumors include fibromas and teratomas. Generally speaking, retroperitoneal tumors, those that are cystic are often benign, and those that are solid are mostly malignant.

　　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 very good, but some tumors are prone to recurrence and malignancy, such as retroperitoneal lipomas and leiomyomas. Lymphomas and neuroblastomas occasionally have curative effects after radiotherapy.

　　1. Abdominal mass:The location of retroperitoneal tumors is deep, and there are usually no symptoms in the early stage. When the tumor reaches a certain size, compression of organs and abdominal pain may be discovered as an abdominal mass. Benign tumors grow slowly, while malignant tumors develop rapidly, and the mass is often located on one side.

　　2. Compression symptoms:When the gastrointestinal tract is compressed, there may be nausea, vomiting, and a sense of fullness; when the rectum is compressed, there may be increased frequency of bowel movements and a sense of anal distension, even deformation of stools and difficulty in defecation; common symptoms of urinary tract compression include frequent urination, urgency, difficulty in urination, or hematuria. Compression of the ureter can lead to hydronephrosis, and compression of blood vessels can cause lower limb edema.

　　3. Pain:Pain in retroperitoneal tumors occurs due to increased tension of the capsule or compression and stimulation of nerves, manifested as lumbar and back pain, perineal pain, or lower limb pain.

　　4. General symptoms:Symptoms such as weight loss, fatigue, decreased appetite, and even cachexia may occur. A few tumors with endocrine function may present with corresponding symptoms.

　　Retroperitoneal tumors mainly originate from the retroperitoneal space. The location is deep, and there are usually no symptoms in the early stage. As the tumor progresses, symptoms such as lumbar and abdominal pain or displacement and compression of organ tissues may appear. Therefore, when there is dull pain and discomfort in the lumbar and abdominal area, one should be vigilant about this disease, strive for early detection, and early treatment. Retroperitoneal tumors are mostly malignant, with rapid development and poor prognosis. Do not seek medical advice or take medicine randomly, as this may delay the disease. At present, surgery is still the main treatment for this disease, supplemented by chemotherapy or radiotherapy. It is not a problem that can be solved by general clinics. Patients who suspect they have this disease are advised to seek medical treatment in hospitals with conditions, in order to achieve good effects.

　　1. The mass is deep and fixed, and when examined in the supine knee position, the mass is fixed to the posterior peritoneum without any downward movement sensation.

　　2. Ultrasound, CT, or retroperitoneal air contrast imaging suggests that the mass is located in the retroperitoneum.

　　Firstly, it is recommended to

　　1. It is recommended to eat more foods that can shrink tumors: jellyfish, oysters, seahorses, crabs, white-banded snakes, clams, horseshoe crabs, kiwi fruit, figs, walnuts, hawthorns, papayas, plums, sugarcane, almonds, lotus seeds, silver ear, melons, gourds, mushrooms, and broad beans.

　　2. For abdominal pain, eat horseshoe crabs, sharks, celery, pumpkin, chives, hawthorn, orange cakes, soy sauce, loofah.

　　3. For edema and reduced urine output, eat scallions, chrysanthemum buds, snails, earthworms, almonds, crabs, kelp, clams, kombu, sturgeon, red beans, crucian carp, lettuce, coconut milk, and snakehead fish.

　　4. Eat figs, wheat bran, hawthorn, shark, mackerel, rabbit meat for irregular bowel movements.

　　Secondly, avoid

　　1. Avoid smoking, drinking, and spicy刺激性 foods.

　　2. Avoid moldy, polluted, hard, rough, fibrous, greasy, sticky, and indigestible foods.

　　3. Avoid fried, smoked, pickled, raw, and mixed foods.

　　4. Avoid gas-producing foods such as soybeans, peas, and sweet potatoes.

　　5. Avoid overeating and forcing down hard foods.

　　Precautions before the treatment of retroperitoneal tumors:

　　1. Diet should be nutritionally balanced, high in protein and vitamins, low in fat and salt, and avoid spicy and刺激性 foods, sweet and greasy foods, grilled, pickled and other foods. Eating regularly and in moderation, and reasonable nutrition are the principles. More foods such as fish, lean meat, eggs, soy products, mushrooms, jujubes, etc. should be eaten.

　　2. Treatment measures should be taken in a timely manner. It is recommended to take Xihuang pills with Xiaoaiping tablets. The principle of Xihuang pills is to reinforce the body and improve the immune function of patients, induce the body to produce mononuclear macrophages, and kill tumors. Xiaoaiping tablets can act directly on the lesion site, kill tumor cells, and prevent the metastasis and recurrence of tumors. The effect of both combined will be better.

　　3. The main treatment is surgical resection, supplemented by preoperative or postoperative radiotherapy and chemotherapy. The surgical incision should be able to fully expose the tumor to avoid compression of the tumor. The separation of the excised tissue should be combined with sharp and blunt dissection, and try to remove the pseudomembrane of the tumor at the same time. If it is difficult, intrapericardial separation surgery can be performed. After the tumor is resected, try to stop the bleeding. If there is a lot of oozing blood and it is impossible to stop the bleeding, a plastic gauze packing and compression hemostasis method can be used, and it can be slowly pulled out later. For large tumors originating from fibrous tissue or fatty tissue that cannot be completely resected, partial resection can be performed, and postoperative radiotherapy should be sought.
