Problems solved by technology

This method needs to be hospitalized for a period of time, the trauma is relatively large, and there may be certain complications
(2) New types of examinations such as PET or PET-CT have the disadvantage of being too expensive, beyond the range that ordinary people can afford, and the medical cost is too high
(3) Liver biopsy, the relatively thick biopsy needle used for puncture, is more damaging to the patient, and the biopsy also has a certain rate of missed detection, and some tumors may also metastasize through the needle tract of the biopsy needle

Embodiment Construction

[0012] The patient was in a good position, and the B-ultrasound was used to determine the location of the small space-occupying lesions in the liver. Mark the body surface, determine the best puncture point, and measure the puncture angle and depth. Routine disinfection, laying sterile drape, local infiltration anesthesia with 1% lidocaine. Ask the patient to hold his breath in a calm breathing state, take a commonly used 21-22G Chiba slender needle, and stab the lesion step by step along the measured angle. Under the guidance of B-ultrasound, adjust the position until the puncture reaches the center of the lesion. According to the size of the lesion, inject 1-1.5ml of normal saline injection per 1cm in diameter, and increase slightly to 2ml if necessary.

[0013] If the lesion is liver cancer, the B-ultrasound image shows that the liquid diffuses evenly in the lesion area. Liver cancer is a solid tumor, and the tumor body is malignant tumor cells. After injection, the drug ...

Abstract

The invention discloses a new application of a normal saline injection in identifying benignity or malignancy of tiny space occupying lesion in liver. The conventional normal saline injection is utilized to achieve unexpected effects. The normal saline injection has high identification sensitivity and specificity, and can be used for clarify a diagnosis on the benignity or malignancy of a tiny space occupying lesion in the liver.

Description

technical field [0001] The invention relates to the field of medicine, and more specifically, relates to a new application of physiological saline injection in the field of diagnosis of liver cancer. Background technique [0002] Hepatocellular carcinoma is the fifth most lethal malignant tumor in the world. About 55% of the new liver cancers in the world are in mainland China every year, and 90% of them are hepatitis B-related liver cancer. It is the second cause of cancer death in my country. The death toll exceeds 200,000. At present, liver cancer resection after early diagnosis of liver cancer is considered to be the first choice for liver cancer treatment, which can provide some patients with a chance of cure. With the development of surgical technology and perioperative management level, the short-term curative effect of the disease has been significantly improved. And if it is misdiagnosed or detected late, the survival rate of patients will be significantly reduced....
