Lipoma is a relatively common benign tumor of the body surface. The main treatment for this tumor is surgical removal. Surgery usually does not require hospitalization, but there are some special cases that require hospitalization. In short, hospitalization is a way to be treated, mainly for safety. 1. Generally speaking, lipomas located in the trunk and extremities that are relatively superficial can be treated surgically on an outpatient basis if they are relatively small and the doctor assesses that the surgery can be completed with local anesthesia during the treatment. After the outpatient excision is completed, the wound will be changed regularly in the outpatient clinic and the dressing will be kept dry. It is not necessary to be hospitalized. 2.Since lipoma is a benign disease, its volume can also appear to grow. In some cases, it is difficult to complete the surgery with local anesthesia when the size of the lipoma increases to a large size. The pain during the procedure is not easily tolerated by the patient and the surgeon is not able to operate better. Therefore, in many cases, nerve block anesthesia or even general anesthesia is required, and these anesthesia methods carry certain risks and require hospitalization. After the surgery is completed, the cavity left behind is also larger due to its size, and a drainage tube is left in place during the surgery to avoid traumatic fluid. Such a surgery with a tube is necessary for hospitalization. The need for hospitalization in the treatment of lipoma depends on the presence of problems that cannot be solved by outpatient surgery. The purpose of inpatient treatment is to facilitate the patient’s recovery and to help the patient better treat the disease.
