Recent years have seen the progressive application of ICG fluorescence imaging technology in colorectal surgery. This study aimed to explore the effectiveness of ICG-guided laparoscopic LLND for rectal cancer.  \nMethods  \nWe applied ICG-guided laparoscopic lateral lymph node dissection in 11 patients diagnosed as rectal cancer with lateral lymph node metastasis.  \nResults  \nAll 11 patients in this group successfully completed ICG-guided laparoscopic LLND for rectal cancer with good lateral lymph node imaging.  \nConclusions  \nICG-guided laparoscopic LLND for rectal cancer is safe and represents a feasible solution, thereby providing valuable guidance for intraoperative lymph node dissection.  \nIntroduction  \nRectal cancer is currently the third most common malignancy worldwide, and its incidence continues to rise. Lymph node metastasis is a main pathway for rectal cancer metastasis and also an important cause of recurrence and death inpatients after radical surgery for rectal cancer. With the development of surgical techniques in recent years, total mesorectal excision (TME) has become the standard surgical procedure for mid-low rectal cancer. Conventional TME does not involve lateral lymph nodes outside the rectal mesentery. However, in cases of  \nCompeting interests: The authors have declared that no competing interests exist.  \nlocally advanced rectal cancers with Lateral lymph node metastasis (LLNM), lateral lymph nodes remain potential sites for local recurrence. As an effective treatment method for removing lateral lymph nodes in rectal cancer, Laparoscopic lateral lymph node dissection (LLND) can considerably reduce the local recurrence rate after rectal cancer surgery, leading to good prognoses. However, the complex anatomical structure of the lateral rectum increases the difficulty of intraoperative localisation and dissection. Indocyanine green (ICG) is a clinically used near-infrared imaging agent that can be applied intraoperatively for lymph node tracing and is known for its good feasibility and safety. This work retrospectively analysed the clinical data of 11 patients with mid-low rectal cancer who underwent LLND with the use ofICG during surgery, explori","cbCaidGUyu7oxhAj","https://ap.wps.com/l/cbCaidGUyu7oxhAj","pdf",3499419,11,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# Introduction\n# Methods\n## Patients\n## Ethics statement","[{\"question\":\"Why is laparoscopic lateral lymph node dissection difficult in rectal cancer?\",\"answer\":\"The complex anatomical structure of the lateral rectum increases the difficulty of intraoperative localisation and dissection.\"},{\"question\":\"How was ICG used in the study?\",\"answer\":\"Patients received ICG guidance during intraoperative lateral lymph node dissection, using ICG fluorescence imaging to trace lymph nodes.\"},{\"question\":\"What were the main results of ICG-guided laparoscopic LLND?\",\"answer\":\"All 11 patients successfully completed ICG-guided laparoscopic LLND with good lateral lymph node imaging, and the study concludes it is safe and feasible.\"}]","Preliminary study of indocyanine green-guided laparoscopic lateral lymph node dissection for rectal cancer | PDF",1790031841,28]
