Supraperitoneal cyst after acute gastroenteritis

Cysts grow on the peritoneum after acute gastroenteritis. This is a mesenteric and peritoneal cyst, which is mainly caused by inflammation. Mesenteric and peritoneal cysts vary in size, and some are very small and may not even cause any symptoms. In addition to understanding the symptoms of mesenteric and peritoneal cysts, we also need to have some understanding of the main treatment methods and determine effective methods for treatment based on our own situation. Let’s take a look below.

Clinical manifestations

Small cysts generally have no symptoms or signs. The clinical symptoms caused by cysts are related to the location and size of the cysts, and whether they displace or compress surrounding tissues and organs. When the cyst grows to a certain size, the following symptoms may appear.

1. Abdominal pain: It often occurs intermittently and recurs repeatedly, lasting from half an hour to several hours. If it is complicated by bleeding, rupture, infection or torsion, there may be severe abdominal pain.

2. Abdominal mass: It is the patient's initial symptom and main sign. The mass has the following characteristics: ① It grows slowly; ② It is generally cystic, with a smooth surface and clear boundaries; ③ The cyst has a large range of motion, especially the lateral mobility; ④ The cyst generally has low tension, feels flexible, and has no obvious tenderness.

3. Abdominal distension: seen in patients with larger cysts. The patient's abdominal circumference gradually increases and may be accompanied by loss of appetite, weight loss, fever, nausea, vomiting, diarrhea, constipation, intestinal obstruction, urinary tract obstruction, anemia, etc. Some patients develop ascites due to cyst rupture, and cyst invasion or intrusion into the intestinal wall may cause bloody stools.

treat

Small cysts do not require treatment. Patients with enlarged cysts should undergo early surgery, or undergo cyst puncture and aspiration of cyst fluid under ultrasound or CT guidance, followed by injection of bleomycin, anhydrous ethanol, etc. into the cyst. Isolated cysts can be removed by cystectomy; if the cyst is closely related to the intestine or is tightly adhered to the mesenteric blood vessels and cannot be separated, it can be removed together with part of the intestine. Simple aspiration of the cystic fluid is not advisable because of the risk of contamination and the possibility of reaccumulation of cystic fluid. If the cyst invades important structures and cannot be removed, a cyst window can be performed to drain the cyst fluid into the abdominal cavity.

If the benign tumor is small, simple tumor resection can be performed, but if it is large, the mesentery and part of the small intestine must be removed together. If the malignant tumor is confined to the mesentery, radical resection should be performed, including the mesentery around the tumor and part of the small intestine; if metastasis has occurred, only palliative resection should be performed to prevent or relieve intestinal obstruction, and combined treatment methods such as chemotherapy and radiotherapy should be used after surgery. The prognosis is poor.
