Medical laser thermal ablation of tumors is a treatment method that uses laser technology to ablate tumors by heating. The following is a detailed description of this method:
1. What is laser thermal ablation?
Laser thermal ablation is a minimally invasive treatment method, which uses high-intensity laser beam to directly irradiate tumor tissue, so as to increase its temperature and achieve the purpose of killing or destroying tumor cells.
2. Principle Laser emission: a specific wavelength of laser light is generated by a specific laser device. Tissue heating: The laser light is absorbed by the tumor cells, causing a rapid increase in intracellular temperature. Cell death: High temperature leads to protein denaturation and structural destruction of cells, thus achieving cell death and necrosis. 3.Indications
Laser thermal ablation therapy is suitable for many types of tumors, including:
Liver cancer Lung cancer Soft tissue tumor Thyroid tumor 4. Advantages Minimally invasive: Compared with traditional surgery, laser treatment has less tissue damage and faster recovery. Accuracy: The laser allows precise positioning and reduces damage to surrounding healthy tissue. Reduce complications: Because it is a minimally invasive surgery, postoperative complications are relatively few. 5. Process Preoperative preparation: including a thorough examination and preoperative evaluation of the patient. Anesthesia: Local or general anesthesia may be provided to the patient. Laser irradiation: The doctor uses an endoscope or other equipment to precisely irradiate the laser beam to the tumor site. Monitoring and evaluation: monitor the treatment process in real time to ensure safety and effectiveness. 6. Precautions Regular follow-up and examination are needed to observe whether there are signs of recurrence. Some patients may have local swelling, pain and other symptoms, which need to be treated according to the doctor’s advice.
Laser ablation of tumors is an innovative medical technology with the following
features
Accuracy
The laser can precisely focus on the tumor tissue and minimize the damage to the surrounding healthy tissue.
Minimal trauma
Laser ablation is usually a minimally invasive procedure with rapid recovery and relatively low risk of postoperative pain and infection.
Reduce bleeding
The thermal effect of
laser can quickly seal blood vessels and reduce the amount of bleeding during surgery.
The indications are extensive
It is especially effective
for certain types of tumors (such as skin tumors, small liver tumors, etc.), and can be used in combination with other treatments (such as radiotherapy, chemotherapy).
Real-time monitoring
The use of imaging techniques (such as ultrasound, CT, etc.) To guide the laser ablation process in real time can improve the accuracy of treatment.
As a minimally invasive surgery,
laser thermal ablation of tumors is safe, but there are still some risks. The following are the possible risks and corresponding countermeasures in the course of treatment:
1. Risk
1.1
. Tissue damage
Description: Laser treatment may cause damage to surrounding healthy tissue.
Countermeasures
: Detailed imaging examinations (such as CT and MRI) were performed before operation to ensure accurate tumor location; precise localization technology was used and real-time monitoring was carried out during treatment.
1.2
. Infection
Description: There is a risk of infection with any surgery.
Countermeasures: preoperative use of antibiotics for prevention, keep the surgical environment sterile; postoperative observation of the wound, if there are signs of infection, timely treatment.
1.3
. Bleeding
Description: Bleeding may occur during treatment.
Countermeasures
: control the output of laser energy to reduce the damage to blood vessels; evaluate the coagulation function of patients before treatment.
1.4
. Pain and discomfort
Description: Feelings of pain and discomfort may occur after surgery.
Countermeasures
: provide detailed pain management plan before operation, and use analgesic drugs as needed; communicate with patients in time to understand their pain situation.
1.5
. Tumor recurrence
Description: Tumor recurrence may occur in some patients after treatment.
Coping measures: regular follow-up and examination after treatment, timely detection of recurrence and further treatment.
1.6
. Thermal damage
Description: Laser treatment can cause excessive heat and damage to surrounding tissue.
Countermeasures
: select the appropriate operation time and distance by adjusting the wavelength and energy of the laser; use the cooling device to protect the normal tissue.
2. Postoperative management
Periodic review: Imaging studies are performed to monitor the condition of the tumor and the recovery of the surrounding tissue.
Maintain good living habits: enhance the body’s immunity and promote postoperative rehabilitation.
Follow the medical supervision: Follow the doctor’s follow-up treatment plan and recommendations, such as regular follow-up, imaging examination, etc.
Sum up
Laser thermal ablation is an effective tumor treatment method, which is suitable for some specific types of tumors. Its minimally invasive and efficient characteristics make it one of the indispensable treatment options in modern medicine. When choosing a treatment plan, patients should fully discuss with their doctors in order to obtain the best therapeutic effect.
