Summary

Early-stage lesions are difficult to identify intraoperatively during colorectal cancer surgery. Therefore, preoperative lesion marking using a colonoscopic approach is crucial to confirm the location and extent of resection during surgery. Preoperative lesion location can help determine the optimal extent of resection, thereby increasing the accuracy of colorectal surgery. This is particularly true for cases requiring surgery after early-stage colorectal cancer or endoscopic tumor resection. Therefore, preoperative marking with indocyanine green (IDG) allows for laparoscopic identification of the lesion. This is crucial because it allows for precise lesion location, thereby enhancing surgical accuracy and preventing the need for unnecessary additional resections.
