What is lymphacentesis
Lymphatic puncture is a medical examination method mainly used to diagnose diseases related to the lymphatic system. In recent years, with the advancement of medical technology, lymphatic puncture has played an important role in tumor diagnosis, infectious disease screening and other fields. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you to the relevant knowledge of lymphatic puncture in detail.
1. Definition and purpose of lymphacentesis
Lymphocentesis is a diagnostic technique that uses a fine needle to extract lymph node or lymph fluid samples for pathological or microbiological examination. Its main uses include:
| Purpose | Description |
|---|---|
| tumor diagnosis | Used to detect lymphoma, metastatic tumors, etc. |
| Infectious diseases | Detect pathogens such as tuberculosis and HIV |
| immune diseases | Assess immune system function |
2. Lymphatic Puncture Operation Procedure
Lymphatic puncture is usually completed by professional doctors in a sterile environment. The specific steps are as follows:
| steps | Operation content |
|---|---|
| 1. Preparation before surgery | Sterilize skin, apply local anesthesia |
| 2. Puncture sampling | Using a fine needle to aspirate lymphatic tissue or fluid |
| 3. Sample processing | Send to pathology or microbiology laboratory |
| 4. Postoperative care | Apply compression to stop bleeding and observe complications |
3. Precautions for lymphatic puncture
Things to note when performing lymphacentesis:
| Things to note | Description |
|---|---|
| Preoperative preparation | Inform the doctor of allergy history and medication usage |
| Cooperation during surgery | Stay still and avoid sudden movements |
| Postoperative observation | Pay attention to complications such as bleeding and infection |
4. Risks and complications of lymphadenectomy
Although lymphatic puncture is a relatively safe examination method, there are still certain risks:
| Risk type | possible performance |
|---|---|
| bleeding | Congestion and swelling at the puncture site |
| infection | Local redness, swelling, heat and pain |
| nerve damage | localized numbness or tingling |
5. Comparison between lymphatic puncture and other examination methods
Compared with other lymphatic system examination methods, lymphatic puncture has unique advantages:
| Check method | Advantages | limitations |
|---|---|---|
| Lymphatic puncture | Directly obtain tissue samples for accurate diagnosis | Invasive procedures |
| Imaging examination | Non-invasive, the overall structure can be observed | Unable to determine the nature of the disease |
| blood test | Simple and easy | Indirectly reflects the status of lymphatic system |
6. Latest research progress in lymphatic puncture
According to hot medical research in the past 10 days, lymphatic puncture technology has the following new developments:
| Research areas | Latest findings |
|---|---|
| minimally invasive techniques | Improved puncture accuracy under ultrasound guidance |
| molecular diagnostics | Genetic testing improves tumor diagnosis rate |
| artificial intelligence | AI-assisted pathological analysis shortens diagnosis time |
7. Frequently Asked Questions about Lymphatic Puncture
Common questions that patients are concerned about are summarized as follows:
| question | Answer |
|---|---|
| Is lymphatic puncture painful? | Basically painless after local anesthesia |
| Need to be hospitalized? | Usually it can be done in an outpatient clinic |
| How long does it take for the results to come out? | Routine inspection takes 3-5 working days |
Conclusion
As an important diagnostic technology, lymphatic puncture plays an irreplaceable role in clinical application. With the advancement of medical technology, the safety and accuracy of lymphatic puncture continue to improve. Patients should fully understand the relevant knowledge when undergoing examination and actively cooperate with the doctor to obtain the best diagnostic effect.
