“doctor, I'd rather die thanopen surgery!"When 58-year-old Mr. Wang was diagnosed with liver cancer, he shouted these words at his attending physician. This man with30年hepatitis Bmedical historyhistory, who witnessed his brother pass fromgastric cancersurgerycomplicationscomplications, harbored"open surgery"a deep fear.
But now, he is smiling as he shows the nearly invisible puncture mark on his abdomen: ""Look, this is where'freeze to death'in my livertumorthey treated me, and I could walk the next day.""
The technology that gave Mr. Wang a new lease on life is the argon-helium cryoablation, which has attracted much attention in tumor treatment in recent years.
Why Do 80% of Tumor Patients Fear Surgery?
In traditional understanding, gettingtumormeans having to"undergo major": large chest/abdominal incisions, weeks-longrecoveryperiod, possible infections andcomplications...These fears make many patients, like Mr. Wang, prefer to give up treatment rather than undergo surgery.
Statistics from a tertiary hospital's oncology department show that approximately 62% of mid-to-late stage patients delay treatment due to fear of surgical trauma. The emergence of argon-helium cryoablation is changing this situation.
用"ice needle"freeze to deathcancer cells，3step to endtumor
Professor Dou Yongchong, Discipline Leader of Oncology at Shenzhen Huaqiao Hospital, introduced: Argon-helium cryoablation, commonly called "argon-helium knife," uses room-temperature high-pressure argon gas as the cooling medium and high-pressure helium gas as the heating medium, hence the name. It is an advanced minimally invasive ultra-low temperature cryoablation tumor technology. In 1998, argon-helium cryoablation technology was approved by the US FDA and received IEC and EMC certification, marking widespread international recognition and application.

QWill the cryoablation process hurt??
A: Local anesthesia is used during treatment,patientsmay feel very slight distension pain, similar to an injection, most people can tolerate it
QWill there becomplications吗?
A: incidence rate is less than5%, mainly mildbleedingor brief fever, far lower thantraditionalsurgery。
QIs it covered by medical insurance??
A: argon-helium cryoablationHas been included in the national medical insurance catalog, with a reimbursement rate of about60%-80%, for details consult the local medical insurance bureau.
