A hard lump inside the stomach that feels like it’s running around is considered to be an occupying lesion in the abdominal cavity, with a higher likelihood of benign disease, including fibroids or lipomas, but also teratomas, simple cysts, and so on. Abdominal color ultrasound as well as abdominal CT should also be performed, and if necessary, surgery is an option. The cause of occurrence can be recurrent chronic inflammatory irritation or congenital developmental abnormalities or malformations. In the absence of clear contraindications to surgery, traditional open surgery or laparoscopic surgery can be chosen to remove the lesion, and pathologic histological examination is required after surgery. During the perioperative period, attention should also be paid to the prevention of infection, and early bed release can promote the recovery of intestinal peristaltic function. For lesions occurring in the intestine, symptomatic treatment such as intravenous nutritional support is also required after surgery, and postoperative attention should also be paid to regular incisional dressing changes to prevent infection, especially in obese patients, and to prevent the occurrence of fat liquefaction.
