Indocyanine Green (ICG)-guided tubal patency assessment is an advanced fluorescence-based method used during laparoscopic gynecological surgery to evaluate the passage of fluid through the fallopian tubes. By combining ICG dye with near-infrared fluorescence technology, surgeons can obtain real-time intraoperative visualization that may assist in determining whether the fallopian tubes are patent.

Tubal patency is an important component of fertility evaluation because obstruction or impaired passage through the fallopian tubes can contribute to difficulty conceiving. When laparoscopy is already being performed for an appropriate clinical indication, fluorescence-guided assessment can provide additional information about tubal passage during the same operative setting.

The technique involves appropriate administration of diluted ICG through the uterine cavity followed by laparoscopic observation using a compatible near-infrared fluorescence imaging system. As the fluorescent dye progresses, the surgeon can observe its movement and assess the appearance of tubal passage. The findings should be interpreted together with the patient's clinical history, fertility evaluation, imaging studies, and other operative findings.

One of the important advantages of fluorescence imaging is its ability to provide visual information that may be difficult to appreciate using conventional visualization alone. ICG-based assessment can therefore be incorporated into modern minimally invasive gynecological procedures where appropriate. However, the technique requires suitable equipment, proper dosing and administration protocols, and trained surgical personnel.

This video provides an educational overview of ICG tubal patency testing, including the underlying principle of fluorescence imaging, laparoscopic visualization, and the potential role of this technique in fertility-related surgery. It is designed for surgeons, gynecologists, trainees, and healthcare professionals interested in contemporary laparoscopic and fluorescence-guided surgical techniques.
