Our Summary

This study deals with the removal of type 2 uterine fibroids, which are difficult to remove surgically because more than half of their volume is inside the muscle tissue of the uterus. The researchers are exploring a less invasive method called hysteroscopic microwave ablation, which requires the careful positioning of the device used to perform the procedure.

The researchers created a computer model to simulate the procedure and then validated it with real tissue experiments. They tested different angles, depths, and positions for the device, and various power levels for different fibroid sizes. They stopped the power once they reached a specific level of heat in the tissue surrounding the fibroid.

They found that the angle of the device didn’t matter as much as its depth and position. They were able to remove between 34.9% and 83.6% of a 3 cm fibroid, and between 34.1% and 67.9% of a 1 cm fibroid, depending on how long they applied heat. They could remove up to 90% of the fibroid if they allowed the surrounding tissue to heat up more than their initial limit.

In conclusion, the study shows that it’s possible to use this method to treat fibroids, and provides information about how the positioning of the device affects the amount of the fibroid that can be removed while controlling the heat in the surrounding tissue.

FAQs

  1. What is hysteroscopic microwave ablation and why is it being explored in the removal of type 2 uterine fibroids?
  2. According to the study, how does the positioning and depth of the device used in hysteroscopic microwave ablation impact the removal of fibroids?

Doctor’s Tip

A doctor may advise a patient undergoing uterine ablation to follow post-procedure instructions carefully, including avoiding heavy lifting and strenuous activities for a period of time. They may also recommend taking pain medication as needed and following up with scheduled appointments to monitor recovery progress. It is important for patients to communicate any concerns or unusual symptoms to their doctor promptly.

Suitable For

Patients who are typically recommended uterine ablation are those who suffer from heavy menstrual bleeding, abnormal uterine bleeding, or other related symptoms caused by conditions such as fibroids or polyps in the uterus. Uterine ablation is often recommended as a minimally invasive alternative to hysterectomy for these patients.

Timeline

Before uterine ablation:

  1. Patient consults with their healthcare provider to discuss symptoms and potential treatment options.
  2. Patient undergoes diagnostic tests such as ultrasound or MRI to confirm the presence of uterine fibroids.
  3. Patient may try conservative treatments such as medication or hormone therapy to manage symptoms.
  4. Patient and healthcare provider decide on uterine ablation as a treatment option.

After uterine ablation:

  1. Patient undergoes pre-operative preparation and instructions from healthcare provider.
  2. Uterine ablation procedure is performed, either through hysteroscopy, radiofrequency ablation, or other methods.
  3. Patient may experience mild discomfort or cramping post-procedure, which can be managed with pain medication.
  4. Patient is monitored for any complications or side effects following the procedure.
  5. Patient may experience a reduction in symptoms such as heavy menstrual bleeding or pelvic pain.
  6. Follow-up appointments are scheduled to monitor the effectiveness of the procedure and address any further concerns.
