What is endoscopic carpal tunnel surgery (ECTS)?

Endoscopic surgery uses a thin, flexible tube with a camera attached (endoscope). The endoscope is guided through a small incision in the wrist (single-portal technique) or at the wrist and palm (two-portal technique). The endoscope lets the doctor see structures in the wrist, such as the transverse carpal ligament, without opening the entire area with a large incision.

The cutting tools used in endoscopic surgery are very tiny and are also inserted through the small incisions in the wrist or wrist and palm. In the single-portal technique, one small tube contains both the camera and a cutting tool.

During endoscopic carpal tunnel release surgery, the transverse carpal ligament is cut. This releases pressure on the median nerve, relieving carpal tunnel syndrome symptoms.

The small incisions in the palm are closed with stitches. The gap where the ligament was cut will eventually fill with scar tissue.

If you have endoscopic carpal tunnel release surgery, you likely will not have to stay in the hospital. You can go home on the same day.
