Comparative clinical efficacy of three surgical modalities for the treatment of malignant tumours of the left hemicolon

There were no significant differences between procedures in the number of lymph nodes cleared or OS, and all procedures successfully achieved radical dissection of the malignant tumors. HALS had lower hospitalization costs and shorter postoperative recovery time of gastrointestinal function, and CLS performed between HALS and RAS. Different surgical procedures have varying impacts on the length of postoperative hospital stay and the degree of postoperative inflammation, so selection should be individualized to each patient.
