In recent years, with the successful implementation of the concept of precision surgery, the use of laparoscopy-endoscopy cooperative surgery in early gastric cancer has proven to be safe and effective. Among these techniques, laparoscopy-assisted endoscopic full-thickness resection combined with indocyanine green fluorescence-guided lymph node dissection is a function-preserving procedure that enables patients to achieve a long-term prognosis comparable to that of radical resection. It offers advantages such as minimally invasive surgery, guaranteed horizontal and vertical resection margins, maximal preservation of the normal gastric wall, and full-thickness suturing to ensure primary healing and the restoration of gastric function. With the growing trend towards personalised and precision surgical treatment of cancer, this procedure is bound to see further development.
