Aunt Li is nearly 80 years old. During the physical examination this year, she found that there were multiple lung nodules in both lungs, including a ground glass nodule in the right lung and a mixed density nodule in the left lung and a malignant tumor to be arranged (as indicated by the red arrows in Figure 1 and Figure 2). After further examination and diagnosis of nodules of primary lung cancer in both lungs, Aunt Li and her family found Chen Enguo, chief physician of the Department of Respiratory and Critical Care Medicine, Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine.
Avoid resection of lung tissue
Both primary lung cancer nodules. If surgery is required, some lung tissue on both sides need to be removed. Aunt Li is nearly 80 years old and has many underlying diseases, and her family is worried about surgery.
Considering Aunt Li’s basic physical conditions and family concerns, Chief Physician Chen Enguo introduced Aunt Li’s argon helium knife cryoablation surgery.
Argon helium knife is full of name: argon helium cryoablation technology. It is an advanced medical technology for minimally invasive ultra-low temperature cryoablation tumors. Its principle is to use high-pressure argon to cool the needle tip to extremely low temperature, and form an ice puck around the needle tip, and then heat the needle tip again through high-pressure helium , so that the secondary freeze-thawing, eventually leading to the death of tumor cells.
Chief physician Chen Enguo suggested that Aunt Li can perform lung cancer nodule ablation first, and then perform the other side ablation at an optional time.
Aunt Li resolutely decided to undergo surgery after learning more. Everything was ready, Chief Physician Jiang Hanliang, Department of Respiratory and Critical Care Medicine of Run Run Shaw Hospital, performed argon-helium cryoablation of left lung cancer nodules under local anesthesia for Aunt Li. Under the guidance of CBCT, Chief Physician Jiang Hanliang placed the ablation treatment needle into the tumor lesion percutaneous puncture, and after confirming the appropriate position of CBCT, it was connected to compressed argon and helium for ablation treatment. The operation was smooth, and Aunt Li said that the entire operation was comfortable and there were no obvious discomfort symptoms after the operation.
argon helium knife treatment process
Tumor disinfection is more accurate
Central physician Chen Enguo introduced that argon helium knife cryoablation is an emerging technology introduced by the Department of Respiratory and Critical Care Medicine of Run Run Shaw Hospital this year. It can be used for early-stage lung cancer patients who cannot tolerate surgery, as well as patients who need local treatment in advanced lung cancer, which can significantly prolong the survival cycle of lung cancer patients and improve their quality of life. Specifically, the freezing temperature of the argon knife drops faster than that of traditional nitrogen, and is more destructive to tumors. The ice hockey around the needle tip during the operation is clearly displayed and can be viewed throughout the process under CT, which can achieve accurate tumor disinfection and effectively protect normal tissue. The argon helium knife has strong repeatability, and the same patient can be treated repeatedly to consolidate and increase the efficacy. In addition, cryoablation can activate the body's immune response, significantly enhance the body's anti-tumor effect, and improve the efficacy of immunotherapy for . Moreover, the argon helium knife is a minimally invasive surgery, local anesthesia, low trauma, and an intrinsic analgesic effect.
converts lung cancer into "chronic disease"
Run Run Shaw Hospital's Department of Respiratory and Critical Care Medicine belongs to the National Respiratory Regional Medical Center jointly built by the Commission and the Provincial Committee. It is the chairman unit of the Respiratory Branch of the Zhejiang Medical Association, the chairman unit of the Zhejiang Pulmonary Vascular Alliance, and the chairman unit of the Zhejiang Respiratory Endoscopy Alliance. It is also the first national training base for PCCM and respiratory endoscopy doctors.
In recent years, Run Run Shaw Hospital's respiratory and critical care medicine department has been constantly innovating and developing new technologies, aiming to benefit more lung cancer patients, so that lung cancer can truly transform from an "incurable disease" to a "chronic disease" and improve the survival rate and quality of life of lung cancer patients.
The Department of Respiratory and Critical Care Medicine of Run Run Shaw Hospital is one of the earliest units in Zhejiang Province to carry out intra-airway intervention diagnosis and treatment. It is the leader of intra-provincial respiratory intervention. At present, various interventional diagnosis and treatment technologies have been fully carried out. Many of these technologies are the first units in the province to carry out independent DSA equipment in the province. It is also the first unit in the province to have independent DSA equipment. It is also the first batch of units to place lung nodules under C-arm CT guidance, bronchoscopy peripheral nodules biopsy under bronchoscopy lung peripheral nodules biopsy under confocal imaging and other endoscopic minimally invasive diagnostic technologies. The comprehensive endoscopic diagnosis and treatment level is leading in China. It has carried out the first ECMO-supported lower bronchoscopy intervention treatment in the country, and has received many difficult intervention referral patients across the country.
