Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Karl Storz New Generation Fetoscope for fetal disorders?

Research shows that using a fetoscope for procedures like laser treatment in twin-to-twin transfusion syndrome can be safe and effective, improving outcomes by allowing precise surgical interventions with minimal risk.12345

How does the Karl Storz New Generation Fetoscope treatment differ from other treatments for fetal disorders?

The Karl Storz New Generation Fetoscope is unique because it allows direct visualization and access to the fetus in the womb, enabling precise diagnosis and potential treatment of fetal disorders. Unlike traditional methods like amniocentesis, which rely on indirect sampling, this fetoscope provides real-time, direct information and can be used for interventions such as fetal blood sampling and surgery.26789

What is the purpose of this trial?

The Researchers are trying to determine feasibility and safety of performing surgery in the womb with the Karl Storz fetoscopes (a tool used to access the baby in the body of the mother). This are new and improved fetoscopes that are not yet approved by the FDA.

Eligibility Criteria

This trial is for pregnant individuals whose babies have been diagnosed with conditions that could potentially be treated through surgery before birth. Specific eligibility details are not provided, but typically participants would need to meet certain health standards and the fetus must be at a stage where in utero surgery is possible.

Inclusion Criteria

Treatment Details

Interventions

  • Karl Storz New Generation Fetoscope
Trial Overview The study is testing new types of fetoscopes by Karl Storz - one curved (11508AAK) and one straight (11506AAK). These tools are designed for surgeries on the baby while still in the womb. The goal is to assess how feasible and safe these procedures are using the new instruments.

Findings from Research

Fetoscopy, performed on 12 women between 12-20 weeks of gestation, is a feasible and safe procedure for examining fetal congenital malformations, with no major complications reported.
The procedure requires significant skill and has a learning curve, but improved visualization was achieved using a 2-mm diameter endoscope, allowing for advanced techniques like laser coagulation in some cases.
The art of fetoscopy: a step toward minimally invasive fetal therapy.Deka, D., Dadhwal, V., Gajatheepan, SB., et al.[2021]
Fetoscopy using a small-diameter instrument was successfully performed in 23 out of 26 fetuses, allowing for direct visualization of the fetus, which is crucial for diagnosing potential issues during pregnancy.
The procedure is relatively safe and uncomplicated, with a success rate of approximately 39% for total visualization of the fetus, making it a valuable tool for high-risk pregnancies, particularly for genetic assessments.

The use of fetoscopy under local anesthesia in 23 pregnant women (13-20 weeks) significantly reduced the risk of fetal damage during procedures like planned surgical abortion.
Fetoscopy allowed for better visualization of fetal structures and successful attempts to obtain fetal blood, indicating its potential for routine use in diagnosing congenital anomalies, although further experience is needed to confirm its safety and simplicity.
