The Value of Near-Infrared Fluorescence Imaging in the Protection of the Recurrent Laryngeal Nerve During Minimally Invasive Esophagectomy

Surgical treatment is currently the best and preferred method for treating esophageal cancer. Esophagectomy is a highly specialized surgery with a high incidence of complications, among which recurrent laryngeal nerve (RLN) paralysis is one of the most common postoperative complications, severely affecting postoperative quality of life. This study adopts a single-center, prospective, open, controlled, non-inferiority validation design. It focuses on patients with esophageal cancer scheduled for esophageal cancer radical surgery. The study aims to include 144 patients with esophageal cancer, randomized in a 1:1 ratio into two groups: the experimental group receiving indocyanine green (ICG) injection and the control group not receiving ICG injection. A comparison will be made between the two groups regarding laryngeal physiological changes one week post-operation. The study will observe the occurrence rate of symptoms related to RLN injury post-surgery, the duration of RLN dissection, and other relevant indicators. The goal is to explore whether the application of NIR-ICG imaging systems can accurately locate the RLN during lymph node dissection in esophageal cancer radical surgery, thereby reducing the risk of RLN injury.
