1. Importance and application of needle tooth extraction
Needle aspiration is an indispensable diagnostic tool in modern medicine, especially in the early detection of cancer and tumors. By extracting a small amount of tissue or cells for pathological analysis, the doctor can accurately determine the nature of the lesion. According to the statistics from the Hong Kong Hospital Authority in 2022, more than 30,000 needle tests are performed in public hospitals every year, with breast cancer and thyroid nodules accounting for the highest percentage.活組織檢查
Through standardized processes and specialized teams (e.g., radiologists and pathologists), public hospitals can reduce the incidence of complications to less than 1%. With the introduction of techniques such as VAB medicine (vacuum-assisted biopsy), the diagnostic accuracy of microcalcified breast lesions has been significantly improved to 95%. For patients concerned about the costs of the private sector, public hospitals are the first choice for Hong Kong residents by meeting international standards and providing services at transparent prices.
2. What is needle extraction?
Needle aspiration, medically known as "percutaneous", is based on the principle of obtaining a sample by inserting a special needle into the target area by image guidance (e.g., ultrasound or X-ray). There are two main categories:
- Fine needle puncture (FNA): Cells are extracted using a 23-25G ultra-fine needle suitable for thyroid or lymph node examination, reducing sample size with minimal trauma
- Gross needle puncture (CNB): A piece of tissue obtained with a needle of 14-18 G has a higher rate of diagnosis of breast and liver lesions
In recent years, the VAB medical technology, which has been widely used in public hospitals in Hong Kong, can obtain multiple tissues at once in combination with a vacuum suction device, which is especially suitable for small lesions. For example, the Breast Center at Queen Mary Hospital reported a 27% increase in the detection rate of atypical hyperplasia.
3. Needle Removal Process in Public Hospitals
1. Make an appointment and prepare
Patients need to bring their referral letter to the specialized outpatient department of a public hospital to register, and the waiting time is about 2-4 weeks. For example, in the case of the Prince of Wales Hospital, a checklist is provided before surgery.
| item | request |
|---|---|
| blood test | Coagulation and platelet tests |
| Image Report | Provide up-to-date ultrasound/contrast results |
| Medication adjustment | Discontinue the anticoagulant for 5-7 days |
2. Needle extraction process
This day is performed by a radiologist and takes about half an hour.
- Local anesthesia will be administered after positioning and disinfection
- Needle insertion under real-time ultrasound monitoring
- 3-5 specimen collections as needed (VAB medical technology can be collected automatically)
- Compress the bandage point
According to data from Lady Youde Eastern Hospital, 90% of patients have only mild pain and do not need additional pain medication.
4. Risks and Side Effects of Needle Aspiration
It is safe to pull a needle in a public hospital, but there is still a 3-5% chance.
- Limited hematology: Occurs more frequently after liver puncture and is usually relieved by ice
- infectA: Strict sterility
- pneumothorax: Lung puncture requires special care, which occurs in about 1-2% of cases.
The Hong Kong Hospital Administration recommends that you seek emergency medical attention if you have any of the following symptoms:
- Bleeding from the puncture site lasts more than 2 hours
- Fever of 38°C or higher
- Difficulty breathing or severe chest pain
5. Needle removal costs and expense reimbursement in public hospitals
The fees charged by public hospitals in Hong Kong are divided into two categories: "qualified persons" and "non-qualified persons".
| item | Eligibility | Who is not eligible? |
|---|---|---|
| Ambulatory needle aspiration | HK$180 | From HK$1,200 |
| Inpatient aspiration | HK$100/day | HK$5,100/day |
Hong Kong ID card holders can reimburse 80% of the cost through medical insurance, with a deductible of up to HK$40,000 per year. For the latest policy enquiries, please call the HA Hotline at 2300 6555.
6. Advantages of Acupuncture in Public Hospitals and Suggestions for Selection
Compared to the private sector, public hospitals have three major advantages:
- Multidisciplinary team support: One-stop service from image judgment to pathology analysis
- Device Update Assurance: Hong Kong's first stereotactic fixation device VAB system was installed at Queen Elizabeth Hospital
- Long-term tracking system: Breast cancer patients can participate in HA surveillance programs
For patients who are financially strained, it is recommended to give preference to the extraction of needles to public hospitals. If the waiting time exceeds the clinically recommended period (2 weeks if a malignancy is suspected), you can consider a referral to a private hospital and apply for a medical voucher subsidy.
