The aim was to study the clinical significance in the preservation of the left colic artery (LCA) and superior rectal artery (SRA) for the laparoscopic resection of sigmoid colon cancer (SCC).
A total of 316 patients with SCC were divided into two groups. Group A received D3 resection with preservation of LCA and SRA, whereas Group B ligatured artery at the root of the inferior mesenteric artery. The operation time, number of resected lymph nodes, blood loss and anastomotic leakage rate were compared.
In Group A, the average operation time was 283.02 ± 51.48 min, the average blood loss was 111.81 ± 77.08 ml and the average lymph node dissection was 14.8 ± 7.7. There was no statistical significance in blood loss and number of resected lymph nodes between Group A and B (P > 0.05). Longer operating time were observed in Group A as compared to Group B (P < 0.05). The anastomotic leakage rate had statistical significance between these two groups (P < 0.05).
Preservation of LCA and SRA was safe and feasible for the laparoscopic surgery of SCC, which could reduce anastomotic leakage rate.
本研究旨在探讨保留左结肠动脉（LCA）和直肠上动脉（SRA）在腹腔镜乙状结肠癌（SCC）切除术中的临床意义。
316例SCC患者分为两组。A组行保留LCA和SRA的D3根治术，B组在肠系膜下动脉根部结扎动脉。比较两组手术时间、切除淋巴结数目、术中出血量及吻合口漏发生率。
A组平均手术时间为283.02±51.48分钟，平均出血量为111.81±77.08毫升，平均清扫淋巴结数为14.8±7.7枚。A组与B组术中出血量及切除淋巴结数目差异无统计学意义（P>0.05）。A组手术时间较B组长（P<0.05）。两组吻合口漏发生率差异有统计学意义（P<0.05）。
保留LCA和SRA用于腹腔镜SCC手术安全可行，可降低吻合口漏发生率。
