Abstract    Several large-scale clinical studies have confirmed the safety and effectiveness of laparoscopic surgery for colorectal cancer，and laparoscopy has become the main modality of colorectal cancer surgical treatment in China.Nowadays，laparoscopic colorectal surgical techniques are still being continuously optimized and improved，and its key techniques are mainly reflected in the following three aspects：（1）complete surgical resection range，（2）appropriate lymph node dissection range，（3）safe digestive tract reconstruction. Rectal cancer surgery should adhere to the principles of total mesorectal excision (TME), ensuring the integrity of the mesorectum and negative circumferential margins. Selective resection of the root of the superior rectal artery and lateral lymph nodes should be based on the depth of tumor infiltration and metastasis. Colon cancer surgery should follow the concept of complete mesocolic excision (CME), involving the complete separation of the colonic visceral fascia from the parietal fascia, clearing up to the third-tier lymph nodes, thereby increasing lymph node retrieval rates and reducing local recurrence rates. The extent of colon resection in colon cancer should meet the requirements of clearing the area of metastatic lymph nodes, following either the Western '10 cm principle' or the Japanese '10+5' principle. Personalized decisions regarding lymph node dissection should consider factors such as tumor location, staging, metastasis, and preoperative imaging. Gastrointestinal tract reconstruction is a crucial component of laparoscopic colorectal cancer surgery. Standardized reconstruction plays a significant role in improving surgical success rates, reducing the incidence of surgical complications, and promoting postoperative patient recovery. Advancing standardized surgical practices, establishing scientific surgical technique assessment tools, and conducting high-quality clinical research are crucial for elevating the standardization level of laparoscopic colorectal cancer surgery in our country.
