What is a splenic cyst and can it be cured?

When the splenic cyst is small, it generally has no effect on the body, so there is no need to pay too much attention to it, but because the splenic cyst can gradually enlarge and increase to a certain extent, it is easy to rupture, which is life-threatening, so any kind of splenic cyst should be operated on in principle**. Previously, total splenectomy was the only option for splenic cysts**. In recent years, considering the importance of preserving the spleen to the body's immune function, partial splenectomy or cystectomy is generally advocated in addition to cysts that are infectious or located in the hilar area of the spleen, especially for pediatric patients.

If the adhesion between the spleen and the surrounding tissues is heavy, and the cyst is uniatrium and combined with purulent infection, incision and drainage of the spleen cyst can be applied; For large unilocular splenic cysts, splenectomy can be performed after evacuating their contents; For purulent and hydatid cysts, attention should also be paid to the surrounding organs during the operation to prevent the spread of infection. In recent years, with the development of laparoscopic technology, laparoscopic splenectomy, splenic cyst resection, and splenic cyst fenestration have also become important options for splenic cysts. From the perspective of traditional Chinese medicine, the spleen is the main movement, so we must pay attention to the regular diet, do not overeat, and have confidence that we will be cured.

The condition of splenic cysts is not fully understood, and true splenic cysts are thought to be due to cystic dilation of the peritoneal epithelium into the spleen parenchyma or into the tubular system of the spleen. Pseudosplenic cysts are associated with trauma, inflammation, childbirth, and splenic infarction.

Classification: Splenic cysts can be divided into parasitic and non-parasitic according to **.

1.Parasitic sacs account for more than 2 3 of splenic cysts. The most common** is echinococcus infection, which usually has no specific symptoms and sometimes causes a ruptured cyst or splenomegaly.

2.Nonparasitic cysts can be divided into true cysts and pseudocysts.

1) True cysts: endothelial cells attached to the cyst are mostly congenital. Usually there are no symptoms, and most patients are found during physical examination or surgery, and most patients do not need **.

For symptomatic patients, cysts smaller than 1 2 can be resected with spleen-sparing surgery; Splenectomy may be considered for patients greater than 1 or 2.

2) Pseudocysts: There are no endothelial cells attached to the cysts, accounting for about 2 3 of non-parasitic cysts, and the ** of splenic cysts is usually formed after absorption of hematomas caused by trauma. The main symptom is left upper quadrant pain with radiation from the left shoulder.

Pain. Pseudocysts smaller than 5 cm can be observed regularly and usually heal on their own. Larger cysts require surgical intervention. Percutaneous drainage is usually not used because it is susceptible to infection and cyst re-formation.

(1) The cause of the disease.

1.Parasitic cysts are composed of echinococcal cysts, which are developed and grown into parasitic cysts by larvae entering the spleen through blood, the inner wall of the cyst is not lined with epithelium, and the cyst contains parasite worm body or eggs and necrotic tissue, and 2% of echinococcosis can have spleen echinococcal cyst, which often coexists with liver and lung echinococcosis, and can be seen in animal husbandry areas in northern China.

2.Nonparasitic cysts include true and pseudocysts.

1) True cysts: there are epidermoid cysts, dermoid cysts, vascular and lymphangial cysts, etc., which differ from pseudocysts in that the inner wall of the cyst is covered with flattened, cubic or columnar epithelium. Among them, epidermoid cysts are more common in young people, often single, with a maximum diameter of up to 31cm, up to 4000ml of fluid in the sac, thick color, light red or brown, and cholesterol crystals; The pathological morphology can be seen, the inner wall of the capsule is lined with squamous epithelium, the basement membrane is flat, there is no epidermal nail process, and there is no ** appendage.

The epidermoid cyst** is unknown, and may be caused by the embryonic stage of the dorsal gastric mesangium or the cells of the mesorenal duct mistakenly developed into the spleen; The pathological evidence of the cyst wall is lined with squamous epithelium and appendages, which is a full-thickness structure, which can include nerve tissue and bone tissue, and there may be white blood cells, fat bodies and cholesterol crystals in the cyst.

2) Pseudocysts: more common than true cysts, accounting for about 80% of non-parasitic cysts, cysts are mostly unilocular, there may be a history of trauma, cysts can be very large, and the cyst wall is not covered by endothelial cells.
