ICG Fluorescence Angiography to Reduce Anastomotic Leak After Laparoscopic Colorectal Resection

This prospective randomized controlled trial evaluates whether intraoperative indocyanine green (ICG) fluorescence angiography reduces clinically significant anastomotic leakage after elective laparoscopic colorectal resection with primary anastomosis. A total of 120 adults were allocated in a 1:1 ratio to ICG-guided perfusion assessment or standard visual perfusion assessment, with 60 participants in each group. In the ICG arm, ICG 0.2 mg/kg was administered intravenously after bowel mobilization and before transection, and near-infrared imaging guided selection of a well-perfused transection margin. Participants were followed for 90 days after surgery for grade B or C anastomotic leakage.
