腹腔镜在乙状结肠癌手术中已被广泛运用，在腹腔镜下行乙状结肠癌根治术也同样经历了长期的发展和改进。在腹腔镜下行乙状结肠癌根治术的治疗要点和注意事项众多，主要包括手术解剖学层面、营养血管的结扎和淋巴结清扫、手术入路的选择及消化道的重建方面；经自然腔道腹腔镜乙状结肠癌根治术在临床也得到了一定程度的运用，但其伦理性和安全性还有待进一步的探讨；在临床上，乙状结肠癌常合并其他良(恶)性疾病，针对这些问题，笔者主要分别探讨合并急性肠梗阻、其他原发恶性肿瘤、胆囊结石及子宫肌瘤时的处理方法和原则；最后探讨腹腔镜减孔操作，尤其是单孔操作下的注意事项及要点。该综述有望为今后乙状结肠癌腹腔镜下的规范化治疗提供有力的支持。

Laparoscopy has been widely used in sigmoid colon cancer, and radical resection of sigmoid colon cancer under laparoscopy has also experienced long-time developments and improvements. There are many treatment points and precautions for laparoscopic radical resection of sigmoid colon cancer, including four major aspects: surgical anatomy, nutrient vessel ligation and lymph node dissection, surgical approach selection, and digestive tract reconstruction; through natural cavity laparoscopic radical resection of sigmoid colon cancer has also been used clinically, but its ethics and safety need to be further explored; clinically, sigmoid colon cancer often merges with other benign and malignant diseases. These problems are mainly discussed separately. The treatment methods and principles of acute intestinal obstruction, other primary malignant tumors, gallbladder stones and uterine fibroids are discussed. Finally, the precautions and points of laparoscopic hole reduction operations, especially single port operations, are discussed. The above results are expected to provide strong support for the standardized treatment of sigmoid colon cancer under laparoscopy in the future.
