Application of minimally invasive surgery in brain tumor treatment

The application of minimally invasive surgery in the treatment of brain tumors has achieved significant progress and effectiveness. The following is a detailed analysis of the application of minimally invasive surgery in the treatment of brain tumors based on the information I searched:

Advances in surgical methods and techniques:

Stereotactic minimally invasive surgery: Through stereotaxic technology, the location of brain tumors can be accurately located and precise resection can be performed, thereby reducing damage to surrounding normal tissues.
Endoscope-assisted minimally invasive surgery: Using the wide-angle imaging function of the endoscope, easily missed compressions and lesions can be found under the microscope, and tumor resection and nerve root decompression can be better completed.
Laser interstitial thermotherapy (LITT): This technology uses laser to ablate tumor tissue and has the advantages of less trauma and faster recovery.
Radiofrequency ablation and cryoablation: These ablation techniques are mainly used in patients with poor physical conditions or who cannot tolerate traditional surgical procedures.

Surgical effectiveness and safety:

Minimally invasive surgery usually has the characteristics of less trauma, less bleeding, and faster recovery. For example, some minimally invasive surgeries only require a small incision about 3-4cm long in the patient's eyebrow, and the tumor can be removed without shaving the hair.
Minimally invasive surgery has lower recurrence rates and higher total resection rates. For example, minimally invasive surgery guided by diffusion tensor white matter tractography has a total resection rate of 86.5% and a morbidity rate of 11.5%.

Multidisciplinary teamwork:

Minimally invasive surgery often requires the cooperation of a multidisciplinary team, including neurosurgeons, radiologists, pathologists, etc., to ensure the accuracy and safety of the surgery.

Intelligent and precise diagnosis and treatment:

With the advancement of imaging technology, minimally invasive surgery has entered the era of intelligent and precise diagnosis and treatment. For example, the Neurosurgery Department of Qilu Hospital carried out the first intraoperative MRI-guided laser interstitial thermal therapy (MRgLITT) for brain glioma under the joint diagnosis guidance of robotic stereotactic biopsy and intraoperative rapid molecular pathology, marking the beginning of minimally invasive brain tumor treatment. Surgery has entered a new era of intelligent and precise diagnosis and treatment.

Clinical application value:

Minimally invasive surgery not only improves patient survival and quality of life, but also reduces postoperative complications and the need for secondary surgeries. For example, stereotaxic targeted minimally invasive surgery can improve patients' neurological function and enhance their daily living abilities.
The application of minimally invasive surgery in the treatment of brain tumors has the advantages of less trauma, fast recovery, and low recurrence rate. With the continuous advancement of technology, its clinical application value is getting higher and higher. In the future, with the application of more high-tech methods, minimally invasive surgery will play a greater role in the treatment of brain tumors.

What are the latest technological advances in minimally invasive surgery in the treatment of brain tumors?

In the treatment of brain tumors, the latest advances in minimally invasive surgical technology are mainly reflected in intelligent and precise diagnosis and treatment. Specifically, the Neurosurgery Department of Qilu Hospital of Shandong University recently carried out the first intraoperative MRI-guided laser interstitial thermal therapy (MRgLITT) for brain gliomas under the joint diagnosis guidance of robotic stereotactic biopsy and intraoperative rapid molecular pathology. This surgery combines intraoperative rapid molecular pathology diagnosis technology and robot-assisted stereotaxic biopsy to guide intraoperative MRI-guided glioma laser interstitial thermotherapy (MRgLITT), realizing minimally invasive cranial surgery. Intelligent and precise.

In addition, Guangxi's first second-generation ROSA robot has also been used in minimally invasive surgery for brain tumors, further improving the level of minimally invasive neurosurgery diagnosis and treatment.

What are the comparative studies on the therapeutic effects of minimally invasive surgery and traditional surgery on brain tumors?

Comparative research on the therapeutic effects of minimally invasive surgery and traditional surgery on brain tumors mainly focuses on the following aspects:

Minimally invasive surgery uses advanced neuroimaging guidance equipment, such as neuronavigation or neuroendoscopy, and uses microscopes and other fiber surgical instruments to achieve the safest possible resection of tumors. The application of this technology makes minimally invasive surgery highly accurate and safe in the treatment of brain tumors such as meningiomas, metastases, gliomas, and pituitary tumors.

Minimally invasive surgery has the advantages of shorter postoperative hospitalization time and lower cost than traditional surgery. In addition, minimally invasive surgery has smaller incisions (usually 0.5cm to 1cm), less postoperative pain, and less bleeding. These features help patients recover faster.

In recent years, minimally invasive microscopy technology combined with the concept of rapid recovery has become increasingly widely used in the diagnosis and treatment of brain tumors. Neurologists are required to rely on their long-term experience accumulation and combine the individual differences of patients to select appropriate surgical methods and carry out personalized and precise treatment.

Although minimally invasive surgery is less invasive, it does not mean it is without risks. It still requires doctors to have superb skills and rich experience to ensure the success rate and safety of the operation.

Minimally invasive surgery has significant advantages in the treatment of brain tumors, including higher treatment accuracy, faster postoperative recovery, lower hospitalization time and costs, etc.

What is the specific mechanism of action of minimally invasive surgery in reducing postoperative complications and secondary surgeries?
The specific mechanism of minimally invasive surgery in reducing postoperative complications and secondary operations mainly includes the following aspects:

Reduce physiological trauma: Minimally invasive surgery is performed through small incisions, reducing damage to surrounding tissues, thereby reducing the incidence of postoperative complications. For example, in minimally invasive surgery for spinal metastases, pain-sensing nerve fibers are destroyed through thermal killing effect, reducing the occurrence of postoperative complications.

Optimizing perioperative management: Minimally invasive surgery in the concept of enhanced recovery after surgery (ERAS) adopts a series of optimization measures to reduce or reduce the physiological traumatic stress of surgical patients, maintain organ function, and promote patients to restore physiological functions in a short time .

Application of visualization technology: The application of visualization technology such as thoracoscopy greatly reduces the risk of intraoperative complications and can provide a better reference for the entry and exit points to ensure the accuracy and safety of the operation.

Reduce inflammatory reaction: Minimally invasive surgeries such as pelvic floor and peritoneal reconstruction can suppress the inflammatory reaction in the patient's body, thereby reducing the risk of grade III to IV complications and reducing the incidence of secondary surgery.

Complete hemostasis and avoidance of excessive traction: In rectal cancer surgery, measures such as complete hemostasis and avoidance of excessive mesenteric separation of the fistula-oral segment, intraoperative compression or excessive traction can effectively reduce the incidence of postoperative anastomotic fistula. This reduces the risk of secondary surgery.

Reduce tissue impact: Minimally invasive surgery has less impact on tissues such as the conjunctiva, sclera, and iris, significantly reducing surgical complications and improving surgical efficacy.

Shorten recovery time: Minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery, and can significantly shorten the patient’s postoperative recovery time.

How to evaluate the recurrence rate and total resection rate of minimally invasive surgery, and the clinical significance of these indicators?

To evaluate the recurrence rate and total resection rate of minimally invasive surgery, as well as the clinical significance of these indicators, detailed analysis can be conducted from the following aspects:

Assessment of recurrence rate:

Recurrence rate is one of the important indicators to measure the effect of minimally invasive surgery. Through postoperative follow-up, the recurrence of patients within a certain period of time is recorded, and the recurrence rate can be obtained. For example, in the treatment of lumbar disc herniation, the postoperative recurrence rate of patients in the PEID and PETD groups was higher than that of the MSLD group, and the difference was statistically significant. In the treatment of incarcerated hernia in the groin, the recurrence rate was 4.55% in the laparoscopic group and 18.18% in the traditional group. There was a significant difference between the two groups.

In the treatment of internal hemorrhoids, the recurrence rates of grade II and III internal hemorrhoids are 7.7% and 8.8% respectively. This shows that endoscopic minimally invasive treatment has good overall efficacy and low recurrence rate, and has good clinical application value.

Assessment of total resection rate:

Total resection rate refers to the proportion of tumors that are completely removed after surgery. This indicator is particularly important for the treatment of malignant tumors because it is directly related to the patient's quality of life and prognosis. For example, in the treatment of head and neck malignant tumors, en bloc resection can better control the patient's local recurrence rate and improve the patient's quality of life.

Clinical significance:

The clinical significance of recurrence rate: A low recurrence rate means good surgical results, fast postoperative recovery, and high quality of life. For example, the recurrence rate of endoscopic minimally invasive treatment of internal hemorrhoids is low, indicating that it is effective and has good clinical application value. However, certain minimally invasive surgeries such as great saphenous varicose veins have a higher recurrence rate (about 22%), which suggests the need to further optimize the surgical method or combine it with other treatments to reduce the recurrence rate.

The clinical significance of total resection rate: A high total resection rate means that the surgery is thorough and can minimize the risk of tumor recurrence, thereby improving the patient's survival rate and quality of life. For example, in the treatment of cervical cancer, the recurrence rate after laparoscopic surgery is higher than that after laparotomy, but its total resection rate is higher, which helps to improve the patient's quality of life.

Evaluating the recurrence rate and total resection rate of minimally invasive surgery requires drawing conclusions through postoperative follow-up and statistical analysis, and making comprehensive judgments based on the clinical manifestations of specific cases.

What are the differences in the application of minimally invasive surgery in the treatment of different types of brain tumors (such as gliomas, solid tumors, etc.)?

The differences in the application of minimally invasive surgery in the treatment of different types of brain tumors (such as gliomas, solid tumors, etc.) are mainly reflected in the following aspects:

Glioma:

Less trauma and high precision: Minimally invasive surgery has small incisions and less damage to surrounding tissues, helping to reduce surgical risks and complication rates. In addition, minimally invasive surgery uses high-precision equipment to more accurately locate tumors and remove tumor tissue, reducing damage to normal brain tissue.

Preoperative precise positioning and stereotactic surgery system: Preoperative precise positioning and the use of stereotactic surgery system make minimally invasive surgery safer and faster in glioma treatment.

Protection of functional areas: For gliomas in functional areas, minimally invasive surgery pays special attention to protecting the function of brain tissue, and minimizes the impact on important functional areas through microsurgery and neuronavigation technology.

Solid tumors:

Multi-site minimally invasive interventional surgery: For multi-site solid tumors, the minimally invasive interventional surgery model uses innovative multi-image-guided minimally invasive interventional surgery to achieve radical cure of the tumor while preserving anatomical structure and immune function.

Individualized treatment plan: Minimally invasive surgery emphasizes individualized follow-up plans in the treatment of solid tumors to ensure the treatment effect while maximizing the preservation of the patient's anatomical structure and immune function.

Minimally invasive surgery mainly emphasizes small trauma, high precision and protection of functional areas in the treatment of glioma;
