Kết quả sớm ứng dụng indocyanine green trong phẫu thuật nội soi ung thư biểu mô tuyến dạ dày tại Bệnh viện Đại học Y Hà Nội

Abstract

Laparoscopic surgery is the primary radical treatment for localized gastric cancer, however, determining resection margins and ensuring thorough lymph node (LN) dissection remain challenging. Recently, Indocyanine Green (ICG) has been applied in laparoscopic gastrectomy to enhance surgical precision through tumor localization and lymphatic mapping. This study aimed to evaluate the efficacy of LN dissection and early outcomes of ICG-guided laparoscopic gastrectomy compared to conventional laparoscopy. A comparison of 41 patients (21 in the ICG group, 20 in the non-ICG group) revealed that the ICG group had a significantly higher number of harvested lymph nodes (23.5 vs 17.6, p = 0.038). ICG also facilitated the detection of lymph nodes beyond the D2 station in 14.3% of cases. Additionally, there were no significant difference between the two groups regarding operative time, blood loss, postoperative complications, or recovery progress. Conclusion: ICG-guided laparoscopic gastrectomy is safe and significantly improves the number of harvested lymph nodes while maintaining similar early postoperative complication rates.
