Summary
Fetal endoscopic surgery has evolved significantly, showing reduced operating times and fewer resources used. Key conditions treated include twin-twin transfusion syndrome and congenital diaphragmatic hernia.
Area of Science:
- Minimally invasive fetal surgery
- Maternal-fetal medicine
- Surgical innovation
Background:
- Minimal access approaches are increasingly used in fetal surgery.
- Fetal endoscopic procedures (fetendo) represent a significant advancement.
Purpose of the Study:
- To report institutional experience with fetal endoscopic procedures.
- To analyze changing techniques and outcome trends in fetendo.
Main Methods:
- Review of 66 fetal endoscopic cases from January 1996 to August 2001.
- Analysis of operative data, including year, procedure type, and outcomes.
- Focus on twin-twin transfusion syndrome and congenital diaphragmatic hernia cases.
Main Results:
- Significant decrease in average operating time (256 to 127 minutes).
- Reduction in ports used (3.8 to 1), pump volume (28.7 to 2.7 L), and blood loss (408 to 29 mL).
- Complications such as chorioamniotic separation and premature rupture of membranes persist.
Conclusions:
- Fetal endoscopic surgery has evolved towards greater efficiency.
- Shorter operating times, fewer/smaller ports, and reduced fluid exchange characterize recent trends.
- Twin-twin transfusion syndrome and congenital diaphragmatic hernia remain primary indications.
