Lipoma is a kind of common saying, which is clinically called lipoma. Lipoma is divided into two kinds of cases: firstly, most of them occur in the parts with rich fat distribution on the body surface, including the front chest, back as well as the limbs and trunk area. If the diameter of lipoma on the body surface is not more than 5cm, no hospitalization is needed. If the diameter is more than 5cm, because the surgical trauma is too large, it may cause local oozing and bleeding, and hospitalization is usually needed to avoid the possibility of bacterial infection secondary to the fact that the oozing and bleeding can’t be drained out sufficiently. Secondly, in the abdominal cavity, such as intestinal tube or mesenteric lipoma, the treatment at this time usually requires local resection of intestinal tube and then reanastomosis, which usually requires hospitalization. Therefore, most of the lipomas or fulminant buns occurring on the surface of the body with small diameters do not require hospitalization for surgery, but for large diameters or intra-abdominal lipomas, hospitalization is required for surgical treatment.
